IPCC Report AR5 September 2013 (WG1) “The Pause”

On September 27 2013 the IPCC released the WG1 report of the IPCC AR5 assessment. UN Secretary General Ban-Ki Moon addressed the IPCC at Stockholm on 27 September. He stated that “the heat is on. We must act”. US Secretary of State John Kerry responded to the report saying “This is yet another wakeup call: those who deny the science…

Plant Productivity Reduction with Climate Change

NASA: Drought Drives Decade-Long Decline in Plant Growth published 08.19.10 by Kathryn Hansen | Source Earth has done an ecological about-face: Global plant productivity that once flourished under warming temperatures and a lengthened growing season is now on the decline, struck by the stress of drought. NASA-funded researchers Maosheng Zhao and Steven Running, of the…

Earth Energy Imbalance

James Hansen explains Earth energy imbalance from anthropogenic forcing and the urgency to act, because of the climate inertia. Earth’s Energy Imbalance By James Hansen, Makiko Sato, Pushker Kharecha and Karina von Schuckmann — January 2012   Deployment of an international array of Argo floats, measuring ocean heat content to a depth of 2000 m,…

NASA Finds ‘Amazing’ Levels Of Arctic Methane And CO2, Asks ‘Is a Sleeping Climate Giant Stirring in the Arctic?’

By Joe Romm / Climate Progress – on Jun 13, 2013: A NASA science team has observed “amazing and potentially troubling” levels of methane and CO2 from the rapidly warming Arctic. Given the staggering amount of carbon trapped in the permafrost — and the fact that methane is a very potent heat-trapping gas — the…

Does Freshwater Runoff in the Arctic change Ocean Circulation to Unlock Methane Hydrate in the Deep Ocean?

Recently freshwater intake into the Arctic Circle have changed ocean currents, in the following a collection of related science, and what if freshwater currents drive warmer water into the deep ocean and unlock methane hydrates? Mechanism have been identified recently. Arctic freshwater input into the North Pacific could serve as a catalyst for methane hydrate…

NASA: Projected U.S. Temperature Changes by 2100

NASA: The average temperature across the continental U.S. could be 8 degrees Fahrenheit warmer by the end of the 21st century under a climate scenario in which concentrations of the greenhouse gas carbon dioxide rise to 800 parts per million. Current concentrations stand at 400 parts per million, and are rising faster than at any…

Most Comprehensive Paleoclimate Reconstruction Confirms Hockey Stick

By Stefan Rahmstorf via Scilogs The past 2000 years of climate change have now been reconstructed in more detail than ever before by the PAGES 2k project. The results reveal interesting regional differences between the different continents, but also important common trends. The global average of the new reconstruction looks like a twin of the…
