May 2013 Earth’s 3rd Warmest May; Central European Floods Cost $22 Billion

By Jeff Masters / Wunderground: May 2013 was the globe’s 3rd warmest May since records began in 1880, according to NOAA’s National Climatic Data Center (NCDC). NASA rated it the 10th warmest May on record. The year-to-date period of January – May has been the 8th warmest such period on record. May 2013 global land…

Bacteria outbreak due to ocean warming

Warming in Baltic Sea linked to Vibrio infection cases +++ Number of cases may rise as oceans warm, become less saline By Nina Chestney Reuters On July 22, 2012: Manmade climate change is the main driver behind the unexpected emergence of a group of bacteria in northern Europe which can cause gastroenteritis, new research by…

Lesson: Arctic Sea Ice Decline

Jennifer Francis, Rutgers University – assesses the broad topic of the Arctic Sea Ice Decline and explains seasonal impacts. Observations, especially since the 1950’s, explain how the “Arctic Amplification” leads to rapid sea ice changes during the summer month. Much more ridging in North America during the winter. And this affects weather patterns, because a…

Catastrophic sea levels ‘distinct possibility’ this century

A breakthrough study of fluctuations in sea levels the last time Earth was between ice ages, as it is now, shows that oceans rose some three meters in only decades due to collapsing ice sheets. The findings suggest that such an scenario — which would redraw coastlines worldwide and unleash colossal human misery — is…

Central West Antarctica among the most rapidly warming regions on Earth

There is clear evidence that the West Antarctic Ice Sheet is contributing to sea-level rise. In contrast, West Antarctic temperature changes in recent decades remain uncertain. West Antarctica has probably warmed since the 1950s, but there is disagreement regarding the magnitude, seasonality and spatial extent of this warming. This is primarily because long-term near-surface temperature…

West Antarctic rapid glacier retreat may be exceptional during the Holocene

Ice loss from the marine-based, potentially unstable West Antarctic Ice Sheet (WAIS) contributes to current sea-level rise and may raise sea level by ≤3.3 m or even ≤5 m in the future. Over the past few decades, glaciers draining the WAIS into the Amundsen Sea Embayment (ASE) have shown accelerated ice flow, rapid thinning, and…

Climate Change Puts Even ‘Safe’ Species at Risk

By Tim Redford, Climate News Network: LONDON—Climate change doesn’t just threaten species that are already vulnerable – it could have alarming consequences for a huge range of birds, corals and amphibians that no-one had considered in danger of extinction before, according to a new study. Wendy Foden of the International Union for the Conservation of…

Carbon Dioxide Is ‘Driving Fish Crazy’

Science Daily: Jan. 21, 2012 — Rising human carbon dioxide emissions may be affecting the brains and central nervous system of sea fishes with serious consequences for their survival, an international scientific team has found. Carbon dioxide concentrations predicted to occur in the ocean by the end of this century will interfere with fishes’ ability…

In Ancient Ice, Clues That Scientists Are Underestimating Future Sea Levels

By John Mahoney / Popsci: The skies do strange things at the NEEM camp, a remote ice-drilling and research facility on the northern Greenland ice sheet. Midnight sunshine. Low clouds of sparkling ice crystals known as “diamond dust.” But when rain fell instead of snow last summer, complete with a rainbow arcing over the camp,…

Video: Lake El’gygytgyn, Pleistocene super-Interglacials and Arctic warmth

John Mason / Skeptical Science: Here is a must-see 2012 presentation by Julie Brigham-Grette of the University of Massachusetts Amherst, covering the research her team has been doing into Lake El’gygytgyn (pronouned El-Guh-Git-Kin), a water-filled meteor crater in Arctic Russia that came into being after the impact of a ~1km diameter space-rock, 3.6 million years ago.…

“Climate Change Is Real” – Former NY Army Corps Commander John Boulé

5/16/13: At the WNET Sandy town hall, the former commander of the New York District, Army Corps of Engineers, John Boulé warns New Yorkers to stop ignoring climate change and start preparing for higher sea level rise and more frequent and more powerful storms.   Brad Johnson: At a May 16 televised forum on the recovery from Superstorm…
