Global warming refers to the rising average temperature of Earth's atmosphere and oceans and its projected continuation. In the last 100 years, Earth's average surface temperature increased by about 0.8 ºC (1.4 ºF) with about two thirds of the increase occurring over just the last three decades.
Warming of the climate system is unequivocal, and scientists are more than 90% certain most of it is caused by increasing concentrations of greenhouse gases produced by human activities such as deforestation and burning fossil fuel. These findings are recognized by the national science academies of all the major industrialized countries.

Stop climate change
Faced with the choice of deadly, dirty, dangerous energy like coal, oil and nuclear power, or safe, clean and renewable power, what would you decide?
Renewable energy, smartly used, can and will meet our demands. No oil spills, no climate change, no radiation danger, no nuclear waste – simply energy we can trust. We can achieve a world with 100% renewable energy. Will you make that choice?
Climate Science
Climate change is a reality. Today, our world is hotter than it has been in two thousand years. By the end of the century, if current trends continue, the global temperature will likely climb higher than at any time in the past two million years.
Climate impacts
No one knows how much warming is "safe". What we do know is that climate change is already harming people and ecosystems. Its reality can be seen in melting glaciers, disintegrating polar ice, thawing permafrost, dying coral reefs, rising sea levels, changing ecosystems and fatal heat waves.

Energy [R]evolution
The Energy [R]evolution is the practical solution to our energy needs. It offers a sustainable path to quit dirty, dangerous fuels by transitioning to renewable energy and energy efficiency.
The Energy [R]evolution is based on five founding principles:
Increase human well-being without fossil fuels.
Fair energy access for all, including the 2 billion people that are left without power in our current fossil-fuel based energy system.
Respect for natural limits: use no more resources the Earth can provide us and don’t emit more than the Earth and the atmosphere can take back (in particular CO2 emissions).
Phase out dirty, dangerous fuels like coal and nuclear.
Use proven, existing renewable energy. Every technology described in the scenario already exists and has been proven to work.
Cool IT Challenge
The IT sector is uniquely positioned to help the world shift to a prosperous clean energy economy, and the Cool IT Challenge is urging IT companies to put forth innovation, mitigate their own carbon footprint, and advocate for significant policy changes in the mutual interest of business and the climate.
