Benefits of Maximizing Southern Exposure for Home Designs

For people planning to build a home and the idea is to have Green Home that offers the owners the chance to make use of renewable resources to save money, then proper orientation of the new home is important. Orienting a new structure to accept the warmth provided by the sun during winter months while avoiding extreme heat in the summer is actually not a new thing. Ancient Roman and Greek homes were oriented and then built with the idea of seasonal exposure. Certain facts influencing building orientations never change. The sun rises still in the east and it sets still in the west. By midday during winter the sunlight is at low angle and at high angle during summer. These are facts that do not change; therefore they should be taken advantage in planning for home building. It is important to position a new structure accordingly so that the daily, as well as the seasonal, motions of the sun can be used in increasing indoor comfort while significant reduction of cooling and heating expenses is also possible.


Benefits of Maximizing Southern Exposure

Sunlight is natural and it is a great source of free warmth. Since daylight is free and sustainable there is no reason why anybody should ignore its power that is readily available. By positioning your home properly according to the movements of the sun you will be able to save energy while creating a healthier and more comfortable living space for you and your family.

Affordability is indeed a good advantage and the cost of trying to maximize sunlight is going to depend on what measures you are going to take. For instance, rearranging your furniture is free and all it takes is some efforts on your part. Other measures can be really inexpensive like painting your wall with lighter reflective paint. Some measure though may require a bit more investment (like installation of light shelves and retrofitting skylights and windows), but will surely pay off in the long run. Harnessing the natural energy from the sun by using solar-powered lighting in illuminating paths and landscapes is also a recommended measure to take.

Maximizing the ability of using a valuable resource like sunlight is indeed helpful in keeping the lights off at daytime and in saving money every minute.

When you make use of the sun’s power to warm and light your home, you are also saving the environment from total destruction. Use of daylight doesn’t need electricity generation and it eliminates greenhouse gasses emission, thus you are making it possible to save the Earth. Additionally solar power utilization involves very little product resource manufacturing, extraction or shipping.

What Should Be Done

For New Homes

Basically, the steps are simple. One good measure to consider is facing the front side of the structure within twenty degrees on the true south. This positions windows that are south-facing and will give them the ability to effectively collect solar energy that will bring in heat inside the home during the cold winter months. It is important though to know that not all windows facing south are going to be effective solar collectors. The degree measurement and the size of the window are important factors. Large windows that are facing extremely to the southwest may overheat the home interior during summer months, and structures that are positioned extremely to the southeast may not get the required sunlight and warmth when winter comes.

Dispersing the light is important and this can be achieved by a properly positioned south-facing window that can illuminate the area from 20 up to 100 times more. When you disperse the light, you reduce glare and heat while you also reduce overhead lighting use.

Painting your ceilings and walls in reflective light colors is also a good idea as well as use of sky tubes or solar lights. You would also benefit well from the power of the sun by installing light shelves that can be useful in reflecting light deeper inside large rooms.

For Existing Homes

For an existing home the best way to take full advantage of the benefits of the sunlight is to start on making renovations. Renovations usually equate high costs but that shouldn’t be the case if you know what to do. The first thing that should be done is to use the resources available. It is also a recommended step to consult a home designer or contractor that is experienced and skilled in passive solar, heating/cooling and electrical design techniques.

It is a good idea to adjust Venetian blind angle so that the light can be aimed where it is needed. When you angle the blind towards your ceiling, light is reflected downwards with no heat gain. Using blinds is ideal because it can reduce the entry of unwanted glare and heat, while you can still benefit from the warmth and the light of the sun.


There are a lot of things to take into consideration if you want to maximize the benefits that can be provided by the power of sunlight. Maximizing southern exposure is one significant consideration. This is a measure that will provide your home with needed shade during sunny summer days. Additionally, proper orientation is going to give you the opportunity to take advantage of sunlight so your home is provided with the required warmth and light during the dark and cold winter days.

If you are building a new house or planning on renovations, getting professional help is a good idea. Professional designers can make your residence a structure that is more affordable to cool and heat. Aside from being energy-wise, proper orientation of your home is also going to give an abode that is highly comfortable and healthier to live in.

Make day-lighting an essential concern in your home building or renovation project by maximizing southern exposure. Daylight is free and it is abundant. It offers natural light and warmth that will give you the chance to save energy, save the Earth and save you and your family’s health.

Zero Energy Building and Benefits

Amid rising concerns regarding the increasing energy prices, the popularly-discussed climate change impact, and the growing global energy independence, reports show that buildings are the main energy consumers in most parts of the world. This fact emphasizes the significance of targeting energy use of the buildings as a key to lessening energy utilization.

The building industry can considerably decrease energy use through the incorporation of energy-efficient strategies and methods into the new buildings’ design, planning, construction, and the operation. Another thing to do is to undertake retrofits to develop the efficiency and effectiveness of the existing buildings. This can result to significant reduction of the fossil fuel dependence due to the increase in the usage of both off-site and on-site renewable energy resources.

From research and discussions, the concept of zero-energy building is turning into reality. The main idea is to ensure that a building will have the ability to produce the same amount of energy it will be using for a year. Currently, there are buildings that are constructed to be highly energy efficient and they are meeting the Net Zero criteria. The number of such buildings may be low as of now, but the fact that the objective is being reached only signals that the world is soon going to be filled with zero energy buildings and the old ones are going to be the thing of the past.

As an outcome of the current construction technology advancements along with intensive academic research and improved systems on renewable energy, creating a zero energy building has become more feasible than before. And despite the fact that there are different metric sets for zero energy, many people agree that zero energy buildings have the following:

  • Excellent building design aimed to reduce energy consumption requirements
  • Effective renewable energy technologies meeting the minimized energy needs

A building called zero-energy is one that consumes almost zero energy from the grid, because it can produce its own required energy. Generally the sum amount of the energy utilized by these building on a yearly basis is about the same amount of the renewable energy generated on the location. Zero-energy buildings though are not totally free from the grid at the start, since most of them still have to depend on the government power sources when the weather will not permit the use of the renewable energy sources. This happens during cloudy days or on winter months and conventional power sources become the main sources of energy. Being zero-net energy though does not mean that a building is no longer responsible for carbon emission. Due to the unavailability of the renewable energy sources at certain times of the year, usage of power from the grid makes a zero-energy building emit greenhouse gases. When a building can eventually generate as much energy as it needs, it will be grid independent successfully, and it will no longer be responsible for the global warming.

The Principle Behind Zero Energy Buildings

The principle behind the construction of zero energy buildings is to have structures that do not emit greenhouse gases and to lessen the need to rely on the use of non-renewable fossil fuels. When a building turns zero-energy it basically becomes a responsible structure that helps in saving the environment from destruction.

Most of the zero-energy buildings still make use of electrical grid for their energy storage; some though are totally independent of the grid. Usually, energy is harvested on-site with the utilization of a permutation of energy-producing technologies like wind and solar, while decreasing the total usage of energy with very efficient HVAC and other lighting and electrical technologies. The goal of zero-energy is becoming the more practical option especially since there is significant decrease in the costs of alternative and renewable energy technologies while there is a more significant increase in the costs of non-renewable fossil fuels.

Benefits of Zero Energy Building

The development of zero-energy buildings turned out to be possible not just through the improvement made in construction and energy techniques and technologies, but it also has been improved significantly through academic research, which gathers accurate energy performance figures on conventional and experimental building structures and offers performance restrictions for complex computer models in predicting the efficiency of the engineering plans.

Saving the Planet

By reducing the dependence of the entire world on non-renewable fossil fuels, which include coal-fired electricity, it is very much possible to reduce the emission of greenhouse gases causing the global warming.

Buildings have big impact on the environment, particularly regarding carbon emissions and energy consumption. Surveys and researches report that in the United States, 48 percent of total energy consumption of buildings is the big contributor to greenhouse gas emissions. Averagely, a household can release about 10 metric tons of carbon dioxide in a year from fossil fuel and electricity use. Since a zero energy building has zero net use of energy, it does not release carbon emissions. This is the ultimate benefit for all mankind, to have a planet to live at for a very long time.

Say Goodbye to Energy Bills

One of the woes of building owners is how to pay the monthly consumption bills. This is true to both commercial and residential building owners. With a building successfully planned and constructed to be Net Zero, energy bills will be non-existence. A zero energy building id effectively designed and built with several features for energy efficiency such as, triple pane window and thicker walls. These features are responsible for creating as much amount of energy from renewable resources – like the solar panels – that it can produce all the electricity it requires.

A zero energy building takes advantage of the power given by natural resources like the sun and the wind. This means there is no need to depend on the grid when it comes to powering up the building and the appliances. In most cases, energy efficient buildings become energy bill-free eventually.

Affordable Homes

If you want a home that is environment-friendly and affordable at the same time, a zero energy home is what you should go for. Though it is a fact that the energy saving features may cost a lot (about 5 to 10 percent more) – which may contribute to a bigger budget in building a zero energy home than a conventional home – perfect planning and smart construction will ensure the affordability of the zero energy homes.

The affordability of a zero energy home will be very evident once it is lived in. This is when the savings from the energy efficient features will be of great use. It will be definitely more affordable to live and work in a building that is not consuming power from the grid.

More Comfortable and Healthier Buildings

People working and living in zero energy buildings can attest to the fact that they are more comfortable. Production is increased and harmony is an everyday luxury. An airtight building can provide the healthiest benefits because:
It provides better air quality indoors through ventilation systems that filter and clean the air. This results in reduced allergens and pollutant, while heat is retained inside the building.

It prevents build up of moisture that result in common mold issues causing major health problems.
It creates a highly comfortable home and work environment with few or zero drafts, minimal dust, plus quiet and reliable cooling or heating.

It creates a peaceful environment because of the thick walls that keep the outdoor noise out.
It has no harmful fumes from propane or natural gas appliances.

Wise Investment

For a standard home or building owner, one of the most common desire is to own a good property investment. A zero energy home or building is said to be the smarter investment for many reasons:

  • A zero energy building’s energy cost remains zero and this is the reason why the value of the property increases.
  • Reports say that foreclosure rate for energy efficient buildings are lower.

More people are now on the lookout for energy efficient homes and they are even willing to pay more.
Zero energy buildings are rot-free buildings due to the double walling. This is another reason why value is increased making a zero energy home a really good investment.

Ideal for Different Types and Sizes of Buildings

Zero energy can work for different sizes and types of buildings. Reports show that offices, universities and K-12 schools are now among the many zero energy buildings in the US. Even low-rising apartments and laboratories are now being constructed to be zero energy buildings. The sizes can go from 50 thousand to 100 thousand square feet.

From Zero Energy Buildings to Zero Energy Communities

Aside from individual buildings, a new trend is coming out and that is of zero net communities. This is indeed a great initiative as a community that is zero net energy can definitely offer a better and healthier living option to people. Who wouldn’t want to walk around a community that is surrounded by great houses and buildings that do not emit carbon dioxide? Wouldn’t it be better to breathe in fresh air day in and day out?
How will the concept of zero energy building translate to zero energy communities? Reaching zero energy from individual building to community level indicates the need to maximize the energy efficiency of every building and structure in the community – these buildings include the existing ones – and to meet the remaining required energy with use of renewable energy.

Providing renewable energy element can be an easier task at community level since sites are characteristically on hand to accommodate high-efficiency and larger-scale solar photovoltaic installations. Further than that, zero energy in the communities can be easily managed eventually.

By balancing options for renewable energy and the energy efficiency cost-effectiveness, communities will be able to discover a minimum-cost path to zero energy. There are different financial mechanisms that are existing today to help in the payment for incremental cost. Bigger asset values, improved comfort, energy independence, lower energy and maintenance costs and the probability for costs for lower life-cycle are among the many reasons why there are many communities that are considering going zero energy.

Zero Net Energy in Existing Buildings

According to reports, about a quarter to the verified zero energy buildings reported has been renovated existing buildings. This only means that it is possible to make old building, not just energy efficient, but also zero net energy.

This concept is ideal for communities aiming to go net zero. Instead of planning and constructing new buildings, existing buildings should be checked and valuated for their potentials in being turned net zero. The fact that many building are now energy efficient is a big bonus because there will be no need to design new power sources. The existing solar panels can be simply improved to ensure the best results.

The first step in turning existing buildings into zero energy buildings in the community level is to find the maximum energy efficiency of the existing buildings. This means to make a detailed analysis of each building and to audit the possible energy savings. The analysis should then be aggregated at community level. Measures for the energy efficiency need to be planned with the use of integrative design standards, analyzing not only the efficiency benefits from every individual measure, but also evaluating the interactions between the building systems and any qualifications for implementing each energy saving source.

Though the idea of zero energy building is still quite uncommon in some countries – even some developed nations – it is being discussed and the benefits being considered. In fact, the popularity and importance of zero energy buildings are booming worldwide. Some countries may not yet able to produce these buildings, but they are interested and looking forward to planning and construction in the future. If the concept of zero energy can reach every nation of the world, this planet is going to be a better and healthier place for everyone.

Solutions for Heat Island Effects

The heat island effect is a phenomenon that results in a dome of gathered heat over a certain location. In most cases, this phenomenon only occurs in urban and industrial areas. This effect is very evident because the heat temperature in that affected locations is significantly higher than that of the surrounding rural areas.

It is a well known fact that the population of Earth is exponentially increasing. Along with population increase, rapid technological development is happening as well. Population pressure is a main cause of both direct and indirect environmental impacts. One unknown, but usually neglected, effect is the unmanageable growth of heat islands. The formation of these temperature phenomena is mainly due to the materials used for the constructions of the city buildings. The fast-paced development of cities also considerably contributes to the heat island effects being felt in urban areas.

Heat island effect can intensify intense hot weather proceedings, which can eventually cause heat stroke that could also lead to certain diseases like organ damage, physiological disruption, and even death. –Higher temperatures accelerate chemical reaction which produces smog or the ground-level ozone. This is a big threat to public health, natural environment and in some communities; it will be harder to meet demands for good air quality.
Heat island effect affects climate change in two ways. First, it contributes to the overall global warming. Second, it constitutes a systematic partiality to monitoring of the global thermal surface, because several network thermal sensors are positioned in areas within heat island effects.

Causes of Heat Island Effect

Heat island effects are consistent parts of the modern urban landscape. These are noticed because of the steep temperature difference between that specific area and the cooler surrounding rural locations. The temperature variation can be as high as ten degrees Fahrenheit.

If you have been living in a rural area and working in the nearby urban town, you have surely noticed that big difference between the two locations heat temperature. The most common reason why heat islands happen in urban cities is because of the need to cut down trees and vegetation to make room for the cities. This kind of practice has significantly changed the temperature of the areas, making them a little warmer than locations that have been left untouched by civilization and technology.

Another reason why heat island effect occurs in a specific area is the modern day activities being performed in that location. For instance, if a city is full of industrial plants, it can only be expected that the air will be filled with greenhouse gasses emissions from the factories.

And as mentioned above, the materials used for building construction also contribute to the increase of this phenomenon. Asphalt and concrete, for instance, are construction materials that absorb enormous amounts of heat, which results in increased surface temperatures in the cities.

Tall buildings are also considered as culprits to the heat islands. They often hinder the air circulation in specific areas, which results in wind speed reduction and lessened natural cooling effects.

There are also many city buildings that have been painted with dark surfaces. What most people do not understand is that a dark surface can absorb more heat and light energy than light-colored surfaces. Dark surface are responsible for making the buildings warmer. This is especially true for buildings that have brick roofing and walls that are painted with dark coatings. For buildings with dark surfaces, the heat is transferred inside the building and then radiated back into the air, adding to the dome of heat island effect over the city.

Use of air conditioning is another cause of the heat island effect. When buildings have dark surfaces, they heat up more quickly, thus they entail more cooling from their air conditioning units. This practice will require more use of energy from the power plants, and this will cause more pollution. Air conditioners also exchange heat with the atmospheric air, which will cause additional local heating. Therefore a cascade effect is in evidence and this contributes to the heat island effect expansion.

Other contributors to the heat island effect are the continued use of non-renewable fossil fuels and the expansion of modern day transportation systems. These contribute significantly to the warmer temperature being felt in the urban areas.

How to Reduce Heat island Effect

One way to effectively reduce the heat island effect is to start anew – like going back to the beginning. This means to go green and plant new trees and grow vegetation. Nothing can be a better solution than to really turn back to nature. This should be done now before it is too late. Planting trees is still possible because the Earth is still nurturing all living things. The importance of trees is in the fact that they provide natural shade. They also enhance the overall appeal of the environment. They provide fruits and they help provide fresh air. If there are more trees in the urban areas, it can only be expected that the air moving around will somehow be fresher and cleaner.

Additionally, it has been shown that plants and trees can help in the reduction of the surrounding temperatures through evapotranspiration – it is a process that occurs when water from plants and the ground is released effectively into the air. This process allows the air to form natural humidity, as well as to create a pleasant, cooling effect. On its own, this process has the ability to reduce hot temperature or heat by at least two to nine degrees Fahrenheit.

However, it is not really that simple to solve the issue of the increasing heat island effects. Planting trees is a process that is actually easier said than done, if the areas to be planted to are the cities. Though it is possible for an individual to plant and grow plants and trees in his own backyard, it is not that easy to do the same task in a bigger location.

In order to significantly reduce the impact of the heat phenomenon, it is essential to strategically plant the trees and vegetation in specific areas to black as much of the sun’s heat as possible during the hottest parts of a day. For instance, trees may be planted on the building’s east side to provide it with a shade from the early morning heat from the sun. Planting on the west side is going to provide the building with enough protection from the scorching afternoon sun.

Some experts will even pronounce that there are certain trees that should be used depending on a specific region. For instance, in Greece, in the city of Chania, it has been proven that the Indian laurel fig is the best tree to plant for fighting against the city’s heat and climate change problems. In a research done in this particular city, five trees have been used for comparison. Humidity and temperatures have been measured in shaded and sunny areas. Then the evapotranspiration rate was determined along with measurement of the Discomfort Index – the level of discomfort the heat supplies to the people. It was the Indian laurel fig that has been discovered to have the highest rate of evapotranspiration. The other four trees used for this experiment are; Canary Island date, stone pine, olive tree and the bitter orange. The relatively high humidity under fig trees contribute significantly to a more pleasant and good micro-climate through higher evapotranspiration rates, which is about 6.9 mm in a day – this results in fairly lowered temperatures.

Areas that are planted with different trees are averagely cooler by about 87 degrees Fahrenheit than open and sunlit pavements. Trees and plants are considered to be the most cost-effective means of aiding the decrease in the heat temperatures being experienced in the urban areas. This is cheaper than installing cooling fans and sun awnings.

Aside from reducing the heat island effect, the use of greenery offers other positive benefits. With trees that surround buildings provide shade that will minimize the need for use of air conditioning. This results in less need for energy to keep these areas cool during the hottest days. Air quality is always better when there are trees around because plants have the ability to effectively store enough carbon dioxide. Green vegetation also reduces greenhouse gases emissions. Lastly, plants and trees make the areas better looking.


Heat island effect refers to city air and urban surface temperatures that are comparatively higher than those in the nearby rural locations. Many suburbs and cities have air temperatures that are up to two to ten degrees Fahrenheit warmer than neighboring rural areas. Elevated environment temperatures can significantly impact communities in a lot of ways; by increasing demands for energy use, increasing costs for air conditioning, increasing pollution levels, and increasing illnesses and mortality.

Different solutions have been put forward for the effective reduction of heat island effect in urban areas. It is up to the communities and local governments to either follow or ignore the proposed solutions. The choices include: planting more trees and plants; painting building surfaces with white; use of sustainable energy resources; and decreased use of air conditioning systems.

What does Eco Design Mean?

Eco design basically means designing for a building or product that will result in the most positive impact on the environment. It is a design style that eliminates the possibility of increasing global warming impact and greenhouse gasses emissions.

In the construction and building industry, many contractors are now incorporating sustainable designs into the options that they offer. Some construction companies are even concentrating on designing green and staying away from tradition building techniques that use traditional, non-renewable and costly materials. Going Green means going natural and if your building is built with natural materials you can only expect the best living and working conditions inside and outside.

Construction designers are now taking on Eco Design concept throughout the designing process; from choosing the materials, to the preferred energy system to be used, and to waste disposal system.

Use of Eco Materials

By using materials sourced naturally, the environment is being saved from losing the supply of non-renewable resources. This is very important in the objective to save the earth from total destruction. Local raw materials are less costly and they reduce environmental shipping costs, greenhouse gasses commissions and fuel consumption.
Aside from using natural materials, use of recycled materials is also an important aspect of eco designing. It is essential though to keep in mind that using recycled and recyclable materials must not generate waste during the manufacturing process or once the materials life cycle has reached its end.

Materials that can be reclaimed and reused include timber or wood and stones. These materials can be obtained from junkyards of directly from the construction site. In most cases, wood and timber are used as support beams for new buildings or to be used as furniture. Stones gathered from excavation sites are useful as retaining wall. When these reclaimed items are used there is less energy consumed because no new products are made and a new natural quality is successfully achieved.

Water Recycling System

Eco Design is also about making sure that water system within the site is sustainably achieved. This is where water recycling comes in and the best way to do this is by installation of rainwater tanks that will harvest water that can be used in many purposes.

Use of grey water is also a good way of avoid wastage of drinking water. In households, it has become essential to use grey water in order to lessen the stresses on the water supplies, reduce the costs and usage of home water, and to support the blooming landscapes. Fresh water is very precious and it is very wise to know how to properly use it so that it can be reused in the objective to live sustainably. That is why it has become essential for Eco design to incorporate effective water recycling systems.

Off-Grid Structures

One of the best ways to achieve sustainable living is to live off-grid. This means not having to rely on electricity power from big companies that make use of power from non-renewable resources. If your home or commercial building has its own power source system, you get to save money on utility bills while living healthier and saving the environment.

Off-grid electricity if clean electricity and it can be achieved by harnessing passive or active energy systems.
Passive Energy

Passive energy system has the ability to heat up a structure with the use of non-mechanical methods, which means optimized use of the natural resources. By using the power of daylight a building can be effective heated up during the cold winter months, which will result in less energy consumption due to less reliance on electric heating systems. By positioning the building according to the position of the sun, your home can have natural heating when you need it.

Installation of green roof is another way to use passive energy and this is achieved by covering your roof with vegetation to create insulation for the regulation of outside temperature. Your green roof is your best weapon in controlling how much heat and coolness enters your home. Additional a green roof is also useful in retaining water and sound proofing your home.

Active Energy

Active energy system aims to provide power for the buildings by using the resources that are readily available like the heat of the sun and powers of wind and water.

One way to use active energy is to use solar power. Today, solar power is the most commonly known renewable energy resource. Solar power can be obtained by using Photovoltaic panels or thermal solar panels. A Photovoltaic panel converts solar radiation into electric current that can provide power for home appliances. A thermal solar panel, on the other hand can significantly reduce diesel and gas consumption and greenhouse gasses emissions.

Other active energy systems include Biomass (energy from organic materials), Geothermal energy (energy from harnessing ground heat) and Wind Turbine (generated energy from wind).

NASA Reports Continues Long-Term Global Warming

According to NASA scientists, 2014 is the warmest year recorded since 1880. There is video that displays the global temperature averages in five-year time series. As time passes by, the red color indicating warming can be seen increasing, meaning that the Earth is indeed getting warmer. The video shows the estimated changing global warmth from 1880 up to 2014.

NASA scientists continue to expect that the earth’s temperatures are going fluctuate year after year, but they are certain of one thing; the earth as a whole has definitely warmed up for up to 1.4 degrees Fahrenheit or 0.8 degrees Celsius since the records in 1880. This is a kind of trend that is significantly driven by the uncontrollable increase of greenhouse gas and carbon dioxide emissions into the earth’s atmosphere.


Global-Warming-1922-1926 Global-Warming-1946-1950 Global-Warming-1981-1984 Global-Warming-2001-2005 Global-Warming-2010-2014

The analysis given by NASA-GISS includes the measurements in temperature gathered from 6,300 weather stations worldwide, buoy-based and ship-based ocean temperature readings, as well as gathered data from the Antarctic research stations. Plugging the measurements into an algorithm allows for the proper estimation of average global temperature.

Warmest Years on Record

NASA scientists reported that as of 2014, the years 2006, 2009 and 2013 are on the same position as the seventh warmest since the year 1880. The record also disclosed that 2005 and 2010 are the warmest years ever prior to the warmest temperature recorded for 2014. This only means that the fluctuating temperatures are not really going down, but rather going to the extremes.

In 2013, it was recorded that the average earth temperatures was at 58.3 degrees Fahrenheit or 14.6 degrees Celsius. This temperature is warmer that the baseline for the mid 20th century of 1.1 degrees Fahrenheit or 0.6 degrees Celsius.

Since 1880, it has been recorded that the average global temperatures increased for about 1.4 degrees Fahrenheit or 0.8 degrees Celsius. This record was based on the analysis performed by the NASA-GISS.

Warmest Years Varied From One Region to Another

The relatively warm temperatures of 2013 were not really experienced around the world. For Australia, 2013 was the hottest year ever, while continental USA, recorded 2013 as the 42nd warmest year in history. The temperature analysis performed by GISS is collected from weather data from over one thousand meteorological stations from all over the world, sea-surface temperature complied through satellite observations and measurements through Antarctic research stations, considering the account station’s history along with the urban heat-island effects. In order to effectively compute the divergence between a given month’s surface temperature and the same place’s average temperature from the year 1951 to the year 1980. This 30 year period works as a foundation for the analysis, and according to the records, it’s been 38 years since a year with cooler than average temperature was recorded.

Regional temperature differences are more powerfully affected by the weather dynamics instead of global mean. For instance, in 2014 in the U.S. there are parts of the East Coast and Midwest that were uncommonly cool, while in Alaska California, Nevada and Arizona, the residents experienced the warmest year recorded.

Different Views and Opinions on the NASA Video

The video itself has received different reactions from different people. Some people mentioned that if you trust Thermometer temperature readings then you probably believe that Global Warming is true and that 2014 is indeed the warmest year recorded.

It was also commented that the video animation displays data from worldwide network of temperature observations. The succession towards greater coverage of the red colors in the course of time is an indication that there is indeed a long-term global warming occurring over the last century.

Another commenter noted that there is one glitch in the video and the description. It was specified that the temperature rise is distorted by the current and more accurate temperature measurements. The noted temperature rise is about similar as the variable. Basically, this means that old and new data do not really correlate, thus there is not much information that would either confirm or deny the claim that 2014 is the warmest year on record.

Out of the whole description, it was also noted that the fifth and the sixth paragraphs are the ones that really made sense. The commenter also mentioned that he never doubted that there are indeed some significant weather pattern changes, but he also does not think that the overall global warming is going to occur that fast.

Another important observation is that some global locations really change their average temperatures, but as the general air currents revolve with different minimal tracks, there still could be a very small change. Unless the world experiences a collective total global system disorder, with generally reversed shifts in magnetic, the climate change trend might still take many hundreds – if not thousands – of years.

This is another view regarding the video animation from NASA: Thermal surveys are a matter of coverage and resolution, while today’s instruments are giving us mounds of data, the very idea that we have produced sufficient coverage and resolution misses the mark. Convection makes surveys very difficult because heat exchange is a moving target. Cleaning up data needs to happen in order to increase the accuracy of a speculative survey. And that’s where we are at in climate science. No credible scientist will instruct the public to take data or algorithms as truth. Science does the best it can, and there is quite a bit of variability within the climate science community regarding the sensitivity of Co2 forcing.

One analysis is that no one really knows what the global temperature is. People can only theorize based on the measurements and the algorithms used in managing them. In order though, to properly perform thermal surveys, advanced technology is needed and it is important to spread the devices out in proportion to their peak coverage concentric. Measurement alone does little in helping the public understand anything about climate. Trial and error has no room for global climate.

Experts’ Views on NASA’s Claim

Experts disagree over the significance of the claim. It was noted however, that there is slight doubt that the fast warming during the 1980s and early the 1990s has slowed. It was added though that there was significant rise in greenhouse gas emissions.

The new figures only showed that the report of global warming stopping is nothing but a myth, probably wishful thinking on the part of some people. Global warming may have slowed down, but to say that it has stopped is something really close to impossible. It was analyzed that the trend for 0.12C global warming per decade is long-term and there is a chance of it picking up again unabatedly, in case there is continued rise in greenhouse gas emissions.

Other experts concluded that if there is a long-term rate of 0.12C per decade then it could only mean that the Earth would be 1C warmer when the century reached its end, and not 4C to 5C as previously claimed.
It was also insisted by climate skeptics that these new figures only showed the warming is at a pause as there was no significant statistic warming trend since 1997. This is because the complete rise over this time period was particularly smaller than error margin.

It was also added that a longer view should be taken since 15 years seems a bit too short. Natural fluctuations are expected, as well as different natural occurrences (like changes in solar output and volcanic eruption) that may increase the global warming rates.


Since the 1880, it has been recorded that the average surface temperature of the earth has significantly warmed by around 1.4 degrees Fahrenheit or 0.8 degrees Celsius. It is a trend mainly driven by the notable rise in carbon dioxide and greenhouse gas emissions into the Earth’s atmosphere.

Since 1880, Earth’s average surface temperature has warmed by about 1.4 degrees Fahrenheit (0.8 degrees Celsius), a trend that is largely driven by the increase in carbon dioxide and other human emissions into the planet’s atmosphere. The majority of that warming has occurred in the past three decades.

The series shown in the animation can be viewed as warm years’ series in warm decades’ series. The individual year’s ranking may have been affected by chaotic and disoriented weather patterns and the long-term warming trends can be attributable to the climate change triggers and these include mainly of the human greenhouse gas emissions.

While 2014 can still be claimed as the earth’s long-term warming trend, some scientists still anticipate that there will be year-to-year variations in the average global temperature caused by disastrous phenomena like the La Niña or the El Niño. These phenomena significantly cool or warm the tropical Pacific and are considered to play significant roles in flattening the long-term global warming trend for the previous 15 years. The 2014 record warmth however, occurred when there was El Niño-neutral year.

NASA monitors the planet’s vital signs from space, land and air using a fleet of satellites plus ground-based observation and airborne campaigns. NASA is constantly developing new ways of observing and studying the planet’s interconnected natural systems along with computer analysis tools and long-term data records for better viewing of how the Earth is changing. GISS shares this exclusive knowledge with the public as they vigilantly work with institutions around the globe, for the contribution of understanding and protection of planet Earth.
