Major sustainability push needed to protect habitat for endangered species
FRISCO — The growing global demand for rubber is threatening biodiversity in Southeast Asia, where expanding plantations are encroaching on protected areas, according to a new study from the University of East Anglia.
Ocean temperatures increasing steadily near West Antarctica
FRISCO — Warming seawater around parts of Antarctica is speeding the melting and sliding of glaciers, and that there is no indication that this trend will reverse, according to researchers with the University of East Anglia.
The study, published in the journal Science, tracked ocean temperatures in the shallow shelf seas of West Antarctica for the last 50 years. The findings also suggest the areas of warmer seawater are spreading, and that other Antarctic areas, which have not yet started to melt, could experience melting for the first time, which would increase the pace of global sea level rise.

“Governments meeting in Warsaw this week need to agree on how to reverse this trend. Emissions must fall substantially and rapidly if we are to limit global climate change to below two degrees. Additional emissions every year cause further warming and climate change,” said the Tyndall Centre’s Professor Corinne Le Quére, who led the global carbon budget report.
Loss of sea ice will eventually lead to decrease in global temperature variability
By Summit Voice
FRISCO — Climate scientists from the UK say their latest study paints a nuanced picture of global temperature variability, outlining recent geographical shifts and projecting an overall long-term decrease in variability as global temperatures rise.
“Fluctuations in annual average temperatures have shown very substantial geographical alteration in recent decades. However, to our surprise, when considered across the globe, total variability has been relatively stable,” said
lead author Dr. Chris Huntingford, with the Centre for Ecology & Hydrology (a joint program of the University of East Anglia and the University of Exeter).
New study projects percent of all plant species will lose half their climatic range
By Summit Voice
FRISCO — Plenty of relatively rare plants and animals have already been flagged because of threats from global warming, but even common backyard plants and animals are likely to decline this century as their climatic ranges shift.
Corrosive waters in Southern Ocean destroying pteropod shells
By Bob Berwyn
FRISCO — Numerous lab experiments have already shown that some shell-forming ocean species will likely suffer as the ocean absorbs atmospheric carbon dioxide and becomes increasingly acidic.
Now, a new study based on 2008 research in the Scotia Sea shows that the shells of tiny marine snails called pteropods are already being dissolved by ocean acidification where atmospheric CO2 being absorbed by the sea is exacerbating acidic conditions resulting from upwelling of cold water from deep below the surface.
The report was timed to precede the 18th UN Climate Change Summit, which starts Nov. 26 in Doha, Qatar. The findings suggest that delegations from some countries have increased in size over the years, while others have decreased, limiting poor countries’ negotiating power and making their participation less effective.
“The UN must recognize that these antiquated structures serve to constrain rather than compel co-operation on international climate policy,” said Dr. Helke Schroeder, with the University of East Anglia’s School of International Development. “The time is long overdue for changes to institutions and structures that do not support decision-making and agreements.”
