On May 11, 2007, the Earth Observatory published Global Warming, a fact sheet outlining the basic principles behind the science of global warming. This follow-up article of questions and answers is based on questions from readers and other common questions about global warming. Many scientists and writers contributed to this article.

Over the last five years, 600 scientists from the Intergovernmental Panel on Climate Change sifted through thousands of studies about global warming published in forums ranging from scientific journals to industry publications and distilled the world’s accumulated knowledge into this conclusion: “Warming of the climate system is unequivocal.”
This is a NASA satellite image of the LarsenB Iceshelf in 2002 as the previously stable shelf of 3,250 square kilometres, anchored on the sea floor and attached to the glaciers that fed it, split up and floated off in about 35 days.
Over the 5 years leading up to this, the Larsen B lost a total of 5,700 sq km above normal iceburg carving events.
