ScienceMag: Medieval Warm Period global, 0.65 °C warmer than present: ‘The largest ocean was 2 °C warmer than today when ancient civilizations exploded’

The authors argue that the Pacific temperatures used to be much warmer sometime during the Holocene (last 11,700 years). For example, some 6,000 years ago, we had the middle Holocene Thermal Maximum. That’s when the great civilizations were born and the Pacific waters near Antarctica and North Pacific were 2.1 °C and 1.5 °C warmer […]

New paper debunks claims that fossil fuel use could cause a mass extinction: Published in Palaeogeography, Palaeoclimatology, Palaeoecology finds that ‘The total amount of carbon needed [to cause a mass extinction] exceeds the modern fossil fuel reservoir’

New paper debunks claims that fossil fuel use could cause a mass extinction http://hockeyschtick.blogspot.com/2013/10/new-paper-debunks-claims-that-fossil.html Climate alarmists have claimed that Earth is on its way to the 6th mass extinction as a result of use of fossil fuels. However, a paper published today in Palaeogeography, Palaeoclimatology, Palaeoecology finds that “The total amount of carbon needed [to […]

New study finds the natural Pacific Decadal Oscillation controls tornado activity, not CO2 – ‘Higher CO2 is correlated with fewer severe tornadoes’

New study finds the natural Pacific Decadal Oscillation controls tornado activity, not CO2 http://hockeyschtick.blogspot.com/2013/10/new-study-finds-natural-pacific-decadal.html A new study finds that the severity and locations of tornadoes is strongly influenced by the natural Pacific Decadal Oscillation, with more severe tornadoes occurring during the warm phase and fewer during the cold phase. The cold phase of the 60-year Pacific Decadal […]

Polar Bear expert: September sea ice ballyhoo and why it doesn’t matter to polar bears – ‘It is the extent in June that is important to polar bear survival. June is the end of the critical spring feeding period for polar bears – healthy bears eat more seals over a shorter period of time from March to June than any other time of year’

September sea ice ballyhoo and why it doesn’t matter to polar bears http://polarbearscience.com/2013/10/20/september-sea-ice-ballyhoo-and-why-it-doesnt-matter-to-polar-bears/ The end of September sea ice summary from the US National Snow and Ice Data Center (NSIDC) finally became available late last week (October 3, “A better year for the cryosphere”). The summary figure NSIDC provides are the average ice extent for […]
