Inconvenient: New paper finds the last interglacial was warmer than today – not simulated by climate models

[Reposted from the Hockey Schtick] A new paper published in Climate of the Past compares temperature reconstructions of the last interglacial period [131,000-114,000 years ago] to climate model simulations and finds climate models significantly underestimated global temperatures of the last interglacial by ~0.67C on an annual basis and by ~1.1C during the warmest month. This…

Claim: study published in Nature shows that small variations in the climate system can result in dramatic temperature changes

Has the puzzle of rapid climate change in the last ice age been solved? Bremerhaven, Germany, August 19th, 2014.  Over the past one hundred thousand years cold temperatures largely prevailed over the planet in what is known as the last ice age. However, the cold period was repeatedly interrupted by much warmer climate conditions. Scientists…

‘unexpected link between solar activity and climate change’ found in Greenland ice

Lund University have published a reconstruction of solar activity vs snow accumulation in Greenland, which indicates a strong correlation between solar minima and a colder climate. ‘The study shows an unexpected link between solar activity and climate change,’ Dr Muscheler said in a press release. ‘It shows both that changes in solar activity are nothing…

SNAP: ‘Data says global cooling, physical model says it has to be warming’

A global temperature conundrum: Cooling or warming climate? From the University of Wisconsin-Madison MADISON, Wis. — When the Intergovernmental Panel on Climate Change recently requested a figure for its annual report, to show global temperature trends over the last 10,000 years, the University of Wisconsin-Madison’s Zhengyu Liu knew that was going to be a problem.…
