Is it plausible that polar bears are 4-5 million years old? Part 3, sea ice | polarbearscience

Miller et al.’s estimation of polar bear population size over time in no way mirrors the dramatic changes in climate that have occurred over the last one million years

GOP Rep Tipton Won't Acknowledge Human-Caused Climate Change Because It Would 'Divide America' | ThinkProgress

In an interview with ThinkProgress, Scott Tipton (R-CO) conceded that climate change exists, but argued that it’s caused by natural climate cycles rather than humans. “Here in the state of Colorado as our tree rings demonstrate, we’ve had droughts long before there were very many people here,” the Tea Party freshman argued. Acknowledging that humans can affect the climate is futile because it would “divide America,” said Tipton.

THE HOCKEY SCHTICK: New paper shows sea temperatures near Antarctica were about 10°C warmer 12,000 years ago

According to a press release from the British Antarctic Survey, temperatures of the Antarctic peninsula were 1.3°C warmer than today 11,000 years ago. Examination of a graph from the paper [below] also indicates nearby sea surface temperatures were up to a remarkable 10°C warmer than the 1961-1990 mean 12,000 years ago as the Earth emerged from the last major ice age. The graph also indicates the Antarctic peninsula warmed at a much faster rate from 13,000 to 12,000 years ago than over the past 1000 years. Greenhouse gases could not possibly explain this radical climate change, especially given the fact that there was little change in greenhouse gases during these periods and that infrared radiation from greenhouse gases cannot heat the oceans.

THE HOCKEY SCHTICK: Nature: New satellite study sparks fresh debate about the melting of Himalayan glaciers

To Lonnie Thompson, a glaciologist at Ohio State University in Columbus, there is an urgent need to understand why these satellite studies differ from each other and from some field measurements, what their sources of errors are, and how they can be better calibrated. “This is the only way to track changes in the 46,000 or so glaciers in the Himalayas and the Tibetan plateau,” he says.

THE HOCKEY SCHTICK: New paper finds global warming weakens South American monsoons

A paper published today in Climate of the Past finds that current South American "monsoon strength is currently rather weak in a 2000-yr historical perspective, rivaled only by the low intensity during the [Medieval Warming Period]." The paper also finds, contrary to warmist claims of increased storm activity from global warming, that the Little Ice Age was associated with the strongest monsoon intensity over the past 2200 years. The paper adds to the published work of over 1000 scientists indicating that the Medieval Warming Period and Little Ice Age were global phenomena, not local as claimed by con- artist Michael Mann.
