A nice bit of anti-warmist propaganda for your Friday. Annoy your easily panicked friends by passing it along!
On the matter of rapid climate change not caused by humans, consider this passage from Nicholas Wade's riveting book about the pre-history of homo sapiens, Before the Dawn: Recovering the Lost History of Our Ancestors (bold emphasis added):
The Pleistocene did not depart quietly but in a roller coaster of climatic swings. After the Last Glacial Maximum, of 20,000 to 15,000 years ago, came a warming period known as the Bolling-Allerod Instadial, during which plants, animals and people were able to move northward again. But the Bolling-Allerod warming, which lasted from 15,000 to 12,500 years ago, was a false dawn. A second cold period, particularly challenging because it began so abruptly, established its grip on Eurasia. Within a decade, it had sent temperatures plummeting back to almost glacial levels and soon had converted to tundra the vast forests of northern Europe. This deadly cold snap is known as the Younger Dryas, after a dwarf yellow rose, Dryas octopetala, that grew amid the tundra.
The Younger Dryas lasted for 1,300 years and ended as suddenly as it began, also in a decade or so, according to the cores drilled from through the Greenland ice cap that serve as an archive of global climate. By 11,500 years ago the world was launched on the Holocene, the inter-ice period that still prevails.
Wade is a science reporter for the New York Times, believe it or not.
More on the Younger Dryas here.
This is nice presentation, and worth watching.
Small point: It says scientists have dismissed (1) variance in sunlight intensity as a cause, but suggests (2) variance in cloud cover might be a cause. But some scientists are suggesting that (1) might be the driver of (2).
I want an Oscar and a Nobel Prize!
Watts Up With That?
"A debunking of the left’s global warming agenda, from Roy W. Spencer, former NASA climatologist and climate expert."
I am shocked, shocked, to read that a global warming denier worked at NASA.
I thought James E. Hansen was the only global warming qualified NASA scientist.
