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…

Life found in the sediments of an Antarctic subglacial lake for the first time

Video: What Lies Beneath: NASA Antarctic Sub Goes Subglacial NASA / JPL February 28, 2013: When researcher Alberto Behar from NASA’s Jet Propulsion Laboratory in Pasadena, Calif., joined an international Antarctic expedition last month on a trek to investigate a subglacial lake, he brought with him a unique instrument designed and funded by NASA to help…

The Ocean Is Going To Start Confusing Fish And Dissolving Seashells

Climate Progress August 27, 2013: Ocean acidification driven by increasing atmospheric carbon levels is a substantial threat to marine life, a new study has confirmed. The study, published in the journal Nature Climate Change, analyzed 167 studies on the effects of ocean acidification on corals, crustaceans, mollusks, fishes and echinoderms, a group which includes starfish…

Climate Extremes and the Carbon Cycle

A new study (doi:10.1038/nature12350) published in nature, explores the impacts of extreme weather events on the carbon cycle. By Bobby Magill / Wunderground, published: August 15, 2013: Devastating drought in the Southwest, unprecedented wildfire activity, scorching heat waves and other extreme weather are often cited as signs of a changing climate. But what if those extreme…

Mass Extinctions Cause Evolutionary Bottlenecks

Science World Report, Aug 14, 2013: Extinctions are occurring at a phenomenal rate these days. As our climate changes and environments are altered, species are disappearing from our planet. Now, scientists are examining mass extinctions more closely. They’ve discovered how after these events in the past, species and ecosystems managed to recover in the aftermath. About…

The Late Triassic Extinction, Persistent Photic Zone Euxinia, and Rising Sea Levels

Böttcher, Pierre LeMetayer, Apratim G. Dastidar and L. Felipe Opazo doi:10.1130/G34183.1 Abstract The Late Triassic mass extinction event is the most severe global warming-related crisis to have affected important extant…

New diseases threatening Britain’s livestock and crops because of global warming

The Independent – June 19, 2013: Bleak assessment of climate change means world was facing ‘a lot more unanticipated events’ Britain faces a wave of deadly new animal and plant diseases that threaten to wipe out crops and livestock as a direct result of global warming, the World Bank’s top agricultural expert has warned. The…

Soil carbon and climate change: from the Jenkinson effect to the compost-bomb instability

Study: Long-term warming equivalent to 10°C per century could be sufficient to trigger compost-bomb instability in drying organic soils Wiley: First generation climate–carbon cycle models suggest that climate change will suppress carbon accumulation in soils, and could even lead to a net loss of global soil carbon over the next century. These model results are qualitatively…

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…

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…
