Record floods, submerged Fenghuang ancient town, Hunan province – July 2014

Severer storms caused record floods in the ancient Chinese town of Fenghuang (Hunan province),  Guizhou province and Jiangxi province. Today (Saturday 18th, July 2014) Rammasun, a super typhoon is approaching the China coast, considered the strongest storm to target China in 40 years.

Tropospheric Ozone in the Anthropocene: Are We Creating a Toxic Atmosphere?

Published on Feb 19, 2014: Jack Fishman explains how elevated ozone levels damage plants, affecting crop yields. Factors among ozone levels include, precipitation and temperature. Further studies found that yields present a consistent function depending on the ozone concentrations. Laboratory simulations suggest that the findings of the yield decline are a trend, which is projected…

Methane explosion investigated as cause for mysterious Siberian sink hole (Update)

Salon: According to Anna Kurchatova, with the Sub-Arctic Scientific Research Centre, the hole could have to do with the thawing of Siberia’s permafrost, a consequence of global warming. The rapid release of gas previously trapped in the ice, she said, could have combined with sand beneath the surface to form an underground explosion. The Siberian…

The California drought and climate disruption

ClimateProgress covered the jet stream connection on Monday: It will be unseasonably chilly in the eastern part of the United States this week, due to a peculiar weather pattern that’s causing deep waves in the jet stream. One of those big waves is bringing cool air down from the northeast Pacific and the Arctic. This…

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…

Climate Effects on Human Evolution

This article explores the hypothesis that key human adaptations evolved in response to environmental instability.  This idea was developed during research conducted by the Smithsonian’s Human Origins Program. Natural selection was not always a matter of ‘survival of the fittest’ but also survival of those most adaptable to changing surroundings. By the Smithonian  Background Paleoanthropologists – scientists who…

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…
