Solar panels will make the earth cooler?

Solar panels to produce electricity, there by reducing the use of fossil fuel emissions of greenhouse gases, and thus combat global warming. At the same time, they can block the light from the sun as Earth's. This additional block should also be able to combat climate change, because less solar radiation means cooler Earth, right?

 

However, scientists recently in "Nature - Climate Change" magazine reported that things are not so simple. Research confirms that solar panels actually let some places hotter. The researchers simulated an idealized scenario: a desert and urban areas completely covered with solar panels Earth. Since the weather depends on many factors, so the team had to simulate an extreme case, to confirm that they really observed changes caused by solar panels.

 

Analog display, additional shielding let are covered area becomes cool, but temperatures drop to change local weather patterns. For example, after installing the solar panels of about 50 years, eastern India and Australia due to the reduced precipitation becomes warmer. Meanwhile, the northwestern United States because of changes in wind patterns have become warmer.

 

Nevertheless, the benefits of solar panels still exceeds the disadvantages. In reality, covering large-scale solar panels, make some areas less than 0.5 degrees Celsius warming. This is much lower than predicted in the next century the global temperature will rise a few degrees, provided that human beings continue to burn fossil fuels. However, the authors suggested that studies have shown that large-scale installation of solar panels should not be the only alternative to fossil fuels.
