*The global warming phenomenon has attracted increasing attention among large numbers of the general public in recent years. Global climate researchers have discovered that the earth's average temperature has risen by 0.75°C over the course of the past century. There is some disagreement among researchers as to the causes of this phenomenon however, the view that mankind's activity has greatly contributed to accelerating global warming in recent years is widely accepted. 

The crux of the problem lies in the burning of fossil fuel materials, such as crude oil and coal, which emit greenhouse gases into the atmosphere, trapping heat close to the Earth.
This increased temperature causes weather changes and extreme weather throughout the world. Scientists point to phenomena such as glacial melting in the Polar Regions, continually increasing sea levels, consecutive years of drought and the outbreak of devastating storms. This phenomenon manifests in Israel in the form of decreasing annual rainfall, harm to water sources and the growth of desert areas in the country's southern region.

In an attempt to halt the global warming phenomenon, or at least slow its progress, researchers and entrepreneurs around the world are working diligently to develop alternative energy sources which will reduce the need to use fossil fuel, thus decreasing the greenhouse gases emitted into the atmosphere. Renewable and clean energy sources such as wind power, geothermal power and solar power are being especially emphasized.
