Energy from renewable resources—wind, water, the sun, biomass and geothermal energy—is inexhaustible and clean.

The costs of technologies to capture that energy are rapidly falling and becoming economically competitive with fossil fuels, while reducing the risk of climate change. Investing in renewable energy creates jobs, fosters economic growth, and improves energy security for countries that lack domestic fossil fuel resources.

Global Warming: 1880-2011

Submitted by glenshewchuck on Wed, 02/08/2012 - 12:26

Global temperatures have warmed significantly since 1880, the beginning of what scientists call the "modern record." At this time, the coverage provided by weather stations allowed for essentially global temperature data. As greenhouse gas emissions from energy production, industry and vehicles have increased, temperatures have climbed, most notably since the late 1970s. In this animation of temperature data from 1880-2011, reds indicate temperatures higher than the average during a baseline period of 1951-1980, while blues indicate lower temperatures than the baseline average.
