New Study claiming global temps highest in 4000 years, contradicted by previous studies
Global warming activists and media outlets are hyping a new study published in Science that claims the Earth is experiencing unprecedented temperatures. See: New York Times: Global Temperatures Highest in 4,000 Years & Associated Press: HEAT SPIKE UNLIKE ANYTHING IN 11,000 YEARS
But the new media touted study is "based on 'reconstructed data' from 73 data sites, pretended to cover space-time of 196 million sq. mi. and 11,300 years"
Another way to view the same claims are as follows: Earth Cooler Today Than 28% of the Past 11,300 Years: 'This is a paper that was bound to cause lurid headlines along lines that Earth is warming faster than at any time during past 11,000 years'
The new study is also counter to a preponderance of existing peer-reviewed studies showing the Medieval Warm Period and the Roman Warming were both as warm or warmer than today without benefit of modern emissions or SUVs.
Penn State Professor Michael Mann has made similar claims of modern temperatures being the warmest, but such "Hockey Stick" temperature claims have been demolished in the scientific literature.
The latest research clearly reveals that the Medieval Warm Period (used to be referred to as the Medieval Climate Optimum) has been verified and was in fact global, not just confined to the Northern Hemisphere. The Center for the Study of Carbon Dioxide and Global Change reported in 2009 that the “Medieval Warm Period was: (1) global in extent, (2) at least as warm as, but likely even warmer than, the Current Warm Period, and (3) of a duration significantly longer than that of the Current Warm Period to date.”
In addition, The Science and Public Policy Institute reported in May 2009: “More than 700 scientists from 400 institutions in 40 countries have contributed peer-reviewed papers providing evidence that the Medieval Warm Period (MWP) was real, global, and warmer than the present. And the numbers grow larger daily.”
Climate Depot has assembled a small sampling of peer-reviewed studies, data and analyses that refute Michael Mann's Hockey Stick temperature claims of unprecedented 20th century warmth.

the warmist decade
since they've kept
accurate records was
the 1930's
and the warmist years
1936-7
nothing recently has been
warmer tnan that
not even 1988-9
which was the warmist in memory
of most people alive now
The Arctic’s 1.5-degree surface temperature anomaly was larger than the global average anomaly. This difference confirms what global climate models were projecting as far back as 30 years ago: that the Arctic region would warm faster than the rest of the planet due to long-term climate change.
The past 6 years in the northern polar region (above 60°N in the Northern Hemisphere) have been the warmest in the historical record. The city of Barrow, located in the northernmost region of Alaska, had a record summer run of 86 consecutive days with minimum temperatures at or above freezing, beginning on June 30. The previous record was 68 days set in 2009.
The warmth is transforming the Arctic. There is less sea ice in the summer, and it is thinner than it used to be, decreasing habitat for polar bears and other marine mammals. Meanwhile, plant productivity — both on land and in the ocean — is increasing. Glaciers and ice sheets are rapidly losing mass, and the melting is freshening the Arctic Ocean.
The Arctic’s 1.5-degree surface temperature anomaly was larger than the global average anomaly.
And again, back 30 years ago, they blamed ozone depletion because of CFC's for THAT problem, which was later debunked.
Quote:False. It's been the warmest on satellite records,which started in the 1970's, which is not exactly thousands of years, which scientists are now seeing evidence of places like Greenland being warm enough that it had TREES! growing there.
Quote:False. there's actually a recent study that showed that the polar bear population actually increased.
Quote: the last time I checked, our food comes from plants, so that would be a GOOD thing.
