The concerns regarding the global warming and the damage sustained by the environment as a result of increased carbon production are on rise. This situation is very detrimental to our eco-system and our environment and of course the ozone layer. The focus is now being shifted to ways of energy production that is environment friendly, cheap and efficient.

Go Green

Solar energy popularity and awareness is on the rise, ample information is now available about it everywhere from internet to magazines and papers. Solar cells and panels are easily available, with the advancement in solar technology, solar panel size has actually reduced and now it does not need a very big space to be installed. If looked after properly the solar panel may have a life that may spread over many years, so it would be one time investments and the profit would be reaped over for many years.

Go Green

You can contribute to the betterment of the environment by making optimum use of the solar energy, help save earth precious and fast depleting resources, controlling pollution and the carbon production. By helping in controlling the environmental damage you will also help yourself save a lot amount in lieu of energy bill and your dependence on the power supplying company will be greatly reduced.

The Solar Panels Available In the Market

A search on the internet shall bring you across a lot of websites that are offering residential energy alternatives, so your dependence on the electric companies may be minimized and the heavy amount that you pay them may be saved.

Today a green home has become a fashion for most of the people. This trend is rapidly increasing because people frequently hear about global warming and other environmental issues. Thus people have to switch to alternative power sources which could not affect the climate.

Understanding about the “DIY” will help you get solar power kits, which are one kind of the alternative to other power sources. Let’s discuss the DIY solar power kits in detail.

Solar power is an energy source that has become increasingly usable due to its many advantages. Some well-known characteristics of DIY solar power kits are:

Globle warming

Pure Energy Provider

As we mentioned above, the global warming and environmental issues are rapidly increasing now-a-days. So people have to search for alternatives which have not an adverse effect on the environment. Solar energy is a new source and yet the best alternative. Solar panels convert solar energy into electric energy, so they are considered a clean source of energy.

Easily Obtainable

Solar power kits are available at every where. Imagine you are purchasing them from your nearest hardware or online store.

Global Warming: Seasons Now Arrive 2 Days Earlier

BERKELEY — Not only has the average global temperature increased in the past 50 years, but the hottest day of the year has shifted nearly two days earlier, according to a new study by scientists from the University of California, Berkeley, and Harvard University.

Just as human-generated greenhouse gases appear to the be the cause of global warming, human activity may also be the cause of the shift in the cycle of seasons, according to Alexander R. Stine, a graduate student in UC Berkeley’s Department of Earth and Planetary Science and first author of the report.

"We see 100 years where there is a very natural pattern of variability, and then we see a large departure from that pattern at the same time as global mean temperatures start increasing, which makes us suspect that there’s a human role here," he said.

Although the cause of this seasonal shift – which has occurred over land, but not the ocean – is unclear, the researchers say the shift appears to be related, in part, to a particular pattern of winds that also has been changing over the same time period. This pattern of atmospheric circulation, known as the Northern Annular Mode, is the most important wind pattern for controlling why one winter in the Northern Hemisphere is different from another. The researchers found that the mode also is important in controlling the arrival of the seasons each year.

The Four Seasons

Whatever the cause, Stine said, current Intergovernmental Panel on Climate Change (IPCC) models do not predict this phase shift in the annual temperature cycle.

Details are published in the Jan. 22 issue of the journal Nature.

Temperatures at any given time of the year can be very different on land than over the ocean, Stine said, and a change in the strength and direction of the winds can move a lot of heat from the ocean onto land, which may affect the timing of the seasons. However, this seems to be only a partial explanation, he said, because the relationship between this pattern of circulation and the shift in the timing of the seasons is not strong enough to explain the magnitude of the seasonal shift.

The researchers also found that the difference between summer and winter land temperatures has decreased over the same 50-year period, with winter temperatures warming more than those in summer. They found that in non-tropical regions, winter temperatures over land warmed by 1.8 degrees Celsius and summer temperatures increased by 1 degree. Ocean warming has been somewhat less.

Stine noted that the study limited its focus to non-tropical regions because the seasons are more pronounced outside the tropics.
