Hmmmm food for thought. What happened to the ancient Egyptians?

Incidentally, were a billion of them involved? How fast did it all happen? I'd like to see those links.

Stay on-topic.

This isn't a global warming causation thread.

Post a single example demonstrating this specious statement.



You can't.

Haven't you heard? The Americans have decided global warming is a hoax and the Earth is actually cooling. If the American public has something to say about science, surely it must be true!

If all the ice on the planet disappeared over night, global warming would still be viewed as a leftist conspiracy in the only country that can lead the rest of the developed world by example.

Take a good look at those glaciers, or what's left of them, we're the last generation to lay eyes on them.

Sigh

Well gee, that's strange. I would have thought the Earth would actually be "cooling" since temperatures have actually been going "down" since 1998.

Or does "going down" mean "going up" now?

Do you mean the theory behind global warming and climate change is a hoax? If you claim this, then you must also be able to prove why it is. That is, what exactly is causing the warming. Aside from a nebulous "Oh, the earth has done this before" response, can you give solid proof? If not, it's not a hoax, it's a theory.

Abstract


Reconstructions of past environmental changes are critical for understanding the natural variability of Earth's climate system and for providing a context for present and future global change. Radiocarbon-dated lake sediments from Lake CF3, northeastern Baffin Island, Arctic Canada, are used to reconstruct past environmental conditions over the last 11,200 years. Numerous proxies, including chironomid-inferred July air temperatures, diatom-inferred lakewater pH, and sediment organic matter, reveal a pronounced Holocene thermal maximum as much as 5°C warmer than historic summer temperatures from 10,000 to 8500 cal yr B.P. Following rapid cooling 8500 cal yr B.P., Lake CF3 proxies indicate cooling through the late Holocene. At many sites in northeastern Canada, the Holocene thermal maximum occurred later than at Lake CF3; this late onset of Holocene warmth is generally attributed to the impacts of the decaying Laurentide Ice Sheet on early Holocene temperatures in northeastern Canada. However, the lacustrine proxies in Lake CF3 apparently responded to insolation-driven warmth, despite the proximity of Lake CF3 to the Laurentide Ice Sheet and its meltwater. The magnitude and timing of the Holocene thermal maximum at Lake CF3 indicate that temperatures and environmental conditions at this site are highly sensitive to changes in radiative forcing.
