WMO: Climate, water and weather extreme data (1970-2012)

The World Meteorological Organisation published the  Atlas of mortality and  economic losses from weather,  climate and water extremes  (1970–2012) on July 11, 2014. The Atlas summarizes the global impacts of the last four decades, based on extreme events such as droughts, extreme temperatures, floods, tropical cyclones and related health epidemics, and the related economic losses. From 1970 to 2012, 8835 disasters,…

New mechanism uncovered, causing potentially rapid Antarctic Glacier melt

An Australian-led research team found that sea levels may rise much faster than previously predicted by models, because changes by disruptive westerly winds, weren’t taken into account. Conservative estimates so far, projected irreversible melting in the course of a few centuries, depending on the temperature increase. Related Each degree of global warming might ultimately raise…

The Runaway Glaciers in West Antarctica

NASA/JPL press release, May 12, 2014: A new study by researchers at NASA and the University of California, Irvine, finds a rapidly melting section of the West Antarctic Ice Sheet appears to be in an irreversible state of decline, with nothing to stop the glaciers in this area from melting into the sea. The study presents…

IPCC Climate Change Report The Five Key Points

The Guardian recently summarized the five keypoints of the new IPCC AR5 Impact Report. The world faces threat to food supply, conflicts over water rights and growing inequality. The only option to is cut emissions By Suzanne Goldenberg (The Guardian): 1. Food threat Climate change is already taking a sizeable chunk out of global food supply…

Spot on! Michael Mann: The irreversible impacts from Climate Change

Mike Mann discusses his new piece in Scientific American, which outlines critical thresholds in climate warming in the not-too-far-off future, based on the sensitivity of Earth climate. Scientific American: Most scientists concur that two degrees C of warming above the temperature during preindustrial time would harm all sectors of civilization—food, water, health, land, national security, energy…

The Rate of Sea-Level Rise

A new study paper out in nature (Nature Climate Change / 2014 / doi:10.1038/nclimate2159), explores why the rise of sea-level has slowed in the last decade. Unsurprisingly the slow-down coincidences with the observed climate hiatus (IPCC AR5, Ocean heat content uptake). Because  heat is distributed differently, depending on the state of ENSO (between El Nino or La Nina). Abstract: Present-day sea-level…

Global Warming Speeds Up Methane Emissions from Freshwater

By Tim Radford (Climate News Network): Scientists think the amount of methane emitted to the atmosphere from freshwater ecosystems will increase as the climate warms, triggering further warming. LONDON, 20 March – British scientists have identified yet another twist to the threat of global warming. Any further rises in temperature are likely to accelerate the release of methane from…
