We calculate that the sub-Antarctic hydrate inventory could be of the same order of magnitude as that of recent estimates made for Arctic permafrost. Once thought to be devoid of life, the ice-covered parts of Antarctica are now known to be a reservoir of metabolically active microbial cells and organic carbon. The potential for methanogenic…Details
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…Details
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…Details
Winter seas are usually free of jellyfish, but scientists warn rising sea temperatures in far north Queensland are prolonging the stinger season.
The Guardian: Meteorologists are debating our role in bizarre weather events. We have the technology for change, but not the political will On Monday, Amory Lovins, physicist, environmentalist, and unassuming colossus of the green movement, appeared in London to talk about energy use. I mention this in the context of the Guardian’s story that meteorologists…Details
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…Details
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…Details
This September 16, 2012 image released by NASA shows the amount of summer sea ice in the Arctic, at center in white, and the 1979 to 2000 average extent for the day shown, with the yellow line. By Eric Alterman | May 30, 2013: In a blog post titled, “Scientists agree on climate change. So…Details
Kevin Anderson presenting at the EcoCities conference at the Bridgewater Hall, Manchester on 14 May 2012.
The release of huge quantities of previously stored “multiyear/deep layer” carbon deposite and equivalent greenhouse gases (CO2/CH4/N2O, from soil and water) can act like a trigger to boot the earth systems. This boot begins initially with a transition phase depending on the rate of emissions and in further development creates several large scale carbon excursions…Details
EurekAlert British Antarctic Survey Jul 25 2012: Scientists have discovered a one mile deep rift valley hidden beneath the ice in West Antarctica, which they believe is contributing to ice loss from this part of the continent. Experts from the University of Aberdeen and British Antarctic Survey (BAS) made the discovery below Ferrigno Ice Stream,…Details
Livescience: When iceberg chunks break off of floating ice shelves, it can serve as dramatic proof of melting — and this traditionally has been considered the main way that these expanses of Antarctic ice become smaller. But new research reveals a disconcerting finding that is invisible to the naked eye: These ice shelves primarily melt…Details
