A century-scale rise in the average temperature of the Earth's climate system and its related effects
Multiple lines of scientific evidence show that the climate system is warming. Although the increase of near-surface atmospheric temperature is the measure of global warming often reported in the popular press, most of the additional energy stored in the climate system since 1970 has gone into ocean warming. The remainder has melted ice and warmed the continents and atmosphere.
- SJS / Siterunner: As many of us point to the 1960s and 70s for the beginnings of the modern environmental movement, and the first widely reported public debates over the science of global warming and climate change, the first reports of the potential danger of climate warming go back to the turn of the century and even further in terms of basic science. Take a look at this news report from Australia in 1912 (as verified by Snopes fact-checking) -- http://www.snopes.com/1912-article-global-warming/
National Climate Program Act, 1978
Looking to the beginnings of US study and action on climate change and global warming. Congressman George E. Brown, scientist-engineer, a chair of the House Science & Technology Committee with a thirty year Congressional career, authors a historic initiative...

James Hansen's Warning to Congress in 1988:
- Ten years after the National Climate Program Act was drafted by Representative Brown and the legislation's passage led by the Congressman began the federal government's study of climate change, impacts and risks.

What we’re doing to the Earth has no parallel in 66 million years, scientists say
"If you dig deep enough into the Earth’s climate change archives, you hear about the Palaeocene-Eocene Thermal Maximum, or PETM. And then you get scared.
"This is a time period, about 56 million years ago, when something mysterious happened — there are many ideas as to what — that suddenly caused concentrations of carbon dioxide in the atmosphere to spike, far higher than they are right now. The planet proceeded to warm rapidly, at least in geologic terms, and major die-offs of some marine organisms followed due to strong acidification of the oceans...."
