Sechstageregen bringt Europa schon das zweite „Jahrhunderthochwasser“ innerhalb von 12 Monaten

Deutscher Wetterdienst (Mai 2014): Das Weltzentrum für Niederschlagsklimatologie (WZN) im DWD hat Ähnlichkeiten und Unterschiede der hydro-meteorologischen Randbedingungen der Überschwemmungen auf dem Balkan im Mai 2014 mit dem Hochwasser in Deutschland im Juni 2013 untersucht. Die Bilder der Überschwemmungen an Donau und Elbe im letzten Jahr sind noch nicht aus dem Kopf, da wird Europa…

Studie:Klimawandel kann EU-Wirtschaft schaden

Von Lucian Haas (Deutschlandfunk), veröffentlicht am 7 Juli 2014. Was der Klimawandel die Wirtschaft kosten wird, kann niemand genau beziffern. Bisher gab es höchstens Prognosen für einzelne Länder, Regionen oder Wirtschaftszweige. Es fehlte eine europaweite Einschätzung. Die haben Wissenschaftler der gemeinsamen Forschungsstelle der EU nun mit einer umfangreichen Studie geliefert. Ende März dieses Jahres präsentierte…

Why is Antarctic sea ice expanding?

By Laura Naranjo (NSIDC), first published January 31, 2014. In the following  an edited version, reposted here with permission. Antarctic sea ice is ruled by very different systems than Arctic sea ice. The reasons behind this increase are complex, and several recent studies show that scientists are still trying to understand them. Ice and wind Atmospheric…

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…

Canada’s shocking oilsands operation (Aerial footage)

DeSmog Canada published a series of aerial photos from Canada Alberta. Alex MacLean is one of America’s most famed and iconic aerial photographers. His perspective on human structures, from bodies sunbathing at the beach to complex, overlapping highway systems, always seems to hint at a larger symbolic meaning hidden in the mundane. By photographing from above, MacLean shows…

Creepy at the EPA

In June of 2009, a story surfaced about the alleged suppression by the US EPA of information related to climate change. The source of the information was reported to be one Dr. Alan Carlin, who, although a real EPA analyst, was in fact, an economist, not a scientist. Distortions of the story, from the usual…

With further Arctic Amplification, How fast will Greenhouse Gas emissions accelerate in the Arctic Circle?

Introduction to Methane Hydrate “Methane Hydrates and Contemporary Climate Change” (2011) IDENTIFICATION This post “A Mechanism for Shallow Methane Hydrate Dissociation”, explores possible mechanism which could release vast quantities of shallow Methane Hydrate into the ocean and atmosphere.       CH4 Release The following studies explore the release of CH4 emissions in the Arctic region. OBSERVATION…

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…

The cost of living in the Anthropocene

What are the true cost of living in the Anthropocene? Wikipedia: The Anthropocene is an informal geologic chronological term that serves to mark the evidence and extent of human activities that have had a significant global impact on the Earth‘s ecosystems. The term was coined recently by ecologist Eugene F. Stoermer and has been widely popularized by the Nobel Prize-winning atmospheric chemist, Paul Crutzen, who regards the…

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…

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…
