Remarkable correlation of Arctic sea ice to solar cycle length

This is interesting, especially since Solar Cycle 23 was quite long. The Hockey Schtick writes: A paper published by the Danish Meteorological Institute finds a remarkable correlation of Arctic sea ice observations over the past 500 years to “the solar cycle length, which is a measure of solar activity. A close correlation (R=0.67) of high significance (0.5…

Hot weather and climate change – a mountain from a molehill?

Guest essay by Steve Goreham Originally published in The Washington Times On Sunday, Death Valley temperatures reached 129oF, a new June record high for the United States, according to the National Weather Service. Temperatures at McCarran International Airport in Las Vegas reached 117oF, tying the previous record set in 1942 and 2005. National Geographic, NBC…

Global Warming theory has failed all tests, so alarmists return to the ‘97% consensus’ hoax

 Guest essay by Joseph D’Aleo, CCM, Weatherbell Analytics National Academies of Science defines a scientific theory as “a well-substantiated explanation of the natural world that can incorporate facts, laws, inferences, and tested hypotheses.” Dr Richard Feynman, Cornell Physicist in a lecture explained how theorys that failed the test of data or experiment are falsified (“wrong”)…

Briffa, Yamal, reputational damage, and all that

Keith Briffa has just published a new paper using the Yamal-Urals regional chronology data, something long sought after via FOIA requests. That data was withheld, citing it wasn’t cooked done with yet, and that releasing it would damage the reputation of CRU scientists. After Climategate in 2009, I’m not sure how CRU’s reputation could be…

Michael Mann says climate models cannot explain the Medieval Warming Period – I say they can't even explain the present

Ice core data shows CO2 levels changed less than 10 parts per million from 1600-1800 during the MWP. From the Hockey Schtick:  A new paper from Schurer et al (with Mann as co-author) finds that climate “models cannot explain the warm conditions around 1000 [years before the present, during the Medieval Warming Period] seen in some…

Evidence for a Global Medieval Warm Period

From CO2Science: Medieval Warm Period (Antarctica) — Summary Was there a Medieval Warm Period somewhere in the world in addition to the area surrounding the North Atlantic Ocean, where its occurrence is uncontested? This question is of utmost importance to the ongoing global warming debate, for if the Medieval Warm Period is found to have…

AGW Proponents Fight Rearguard Action As Political Climate Science Fails

Guest post by Dr. Tim Ball Proponents of the anthropogenic global warming (AGW) hypothesis are cornered. They made a political choice to prove rather than disprove the hypothesis, as the scientific method requires. It failed, as IPCC projections (range of predictions?) indicate, but instead of abandoning or modifying the hypothesis, as normal science requires, they’ve…
