Climate denial is so passé
Climate 'hockey stick' is revived
A new study by climate scientists behind the controversial 1998 "hockey stick" graph suggests their earlier analysis was broadly correct. Michael Mann's team analysed data for the last 2,000 years, and concluded that Northern Hemisphere temperatures now are "anomalously warm". Different analytical methods give the same result, they report in Proceedings of the National Academy of Sciences. The 1998 hockey stick was a totem of debates over man-made global warming. The graph - indicating that Northern Hemisphere temperatures had been roughly constant for 1,000 years (the "shaft" of the stick) before turning abruptly upwards in the industrial age - featured prominently in the Intergovernmental Panel on Climate Change's (IPCC) 2001 assessment.
Another plank of climate denial theory comes crashing down, a bit like their 32 000 ‘scientists’ who signed that global warming isn’t man made on-line petition, because when you look at the listed professions of the 32 000 ‘scientists’ it boils down to 1.6% who actually study any climate science who don’t believe global warming is man made. Hardly as impressive as the 32 000 ‘scientists’ claim is it? Those wacky climate deniers, when will we stop tolerating them blocking the debate for real sustainable change? Add to this the methane issue and the non-linear warming event methane can create by pushing temperatures up by 10 degrees in a short period of time which I’ve been blogging about since I started blogging and we are inch by inch moving towards those tipping points from which we can’t change direction on climate change.
Methane Discharges In The Arctic Pose Threat To Earth's Climate
VLADIVOSTOK, Aug 20 (Bernama) -- Methane discharges in the permafrost break-up process in the Arctic pose a threat to the entire terrestrial climate, Russian news agency, Itar-Tass, reported. This hypothesis, put forward by scientists at the Pacific Oceanology Institute (POI) of the Far Eastern Branch of the Russian Academy of Sciences is being corroborated by this year's research, Igor Semiletov, participant in a research expedition, and staff member of the POI Arctic Research Laboratory, reported by telephone from board the hydrographic research vessel "Yakov Smernitsky" on Wednesday.
