What is Global Warming? - National Wildlife Federation

What is Global Warming? - National Wildlife Federation:

"Global warming is...happening now
The Earth's atmosphere has already warmed by 1.5 degrees Fahrenheit since 1900. This warming signal is also found in ocean temperatures, soil temperatures, melting glaciers and melting polar ice caps. It has been linked to widespread impacts on ecosystems around the planet. This preponderance of evidence all points to the conclusion that our planet is warming and natural systems are struggling to keep up. Read more...

Global warming is...human caused
The role of atmospheric carbon dioxide (CO2) in warming the Earth's surface was first demonstrated by Swedish scientist Svante Arrhenius more than 100 years ago. Scientific data have since established that, for hundreds of thousands of years, changes in temperature have closely tracked with atmospheric CO2 concentrations. Since the Industrial Revolution, the burning of coal, oil and natural gas has emitted roughly 500 billion tons of CO2, about half of which remains in the atmosphere. This CO2 is the biggest factor responsible for recent warming trends. Read more...

Global warming is...accelerating"

The popular late night radio show "Coast to Coast AM" presents, in my view, about 80% pseudo-science and nonsense. But the other 20% makes for cutting edge discussions you won't find elsewhere. Last night's program was such a night, with Art Bell, the show's semi-retired founder, stepping in to interview the head of the National Wildlife Federation about various environmental issues facing us today. Bell, unlike the show's replacement host, trusts science. He believes global warming is a fact, not a hoax. He is terrified of the consequences and rightly so. So last night was a sobering look at our bleak future.

I don't see the situation turning around. One way or another, Nature wins, and if this means catastrophe for our species, so be it.

This may become an issue in the next presidential election. If so, one side may be saying that the cure for all our ills is divine intervention.

So this is what we've come to.
