New Report
-- On Thin Ice: How Cutting Pollution Can Slow Warming and Save Lives
Dear
Climate-L Colleagues-
We would
like to bring to your attention a new report, detailing how changes in the
cryosphere – regions of snow and ice – are occurring around the world as a
result of climate change. The report
also features new modeling that indicates how actions to address common
pollution sources can help lower the risks of these changes while benefiting
health and development.
These are
the dual messages of warning and promise from On Thin Ice: How Cutting
Pollution Can Slow Warming and Save Lives, which reviews the most recent
research on the impacts of climate change in cryosphere regions around the
globe – the Arctic, Antarctica, Himalayas, Andes and East Africa – building on
research since the International Polar Year.
The report, released today by the World Bank and International
Cryosphere Climate Initiative (ICCI), then goes on to explore which actions --
in addition to cuts in carbon dioxide emissions -- might help slow these
changes; through the efforts of an international team of modelers focusing on
traditional air pollution sources.
The report
notes the reality of cryosphere warming today: twice the rate or more of the
global average. This rapid warming then
increases the risk of other impacts, such as higher sea level rise, and release
of methane and CO2 from permafrost and near-coastal regions off Siberia. Loss of Arctic sea ice by the middle of this
century could speed warming further.
These possibilities, and even more uncertain events such as greater
Greenland melt or the collapse of the West Antarctic Ice Sheet, all are risks
that increase as temperatures in the cryosphere rise.
Over a year
in the making, the report and modeling involved an extensive review of
cryosphere research, and the work of an international team of modelers from
NASA, the EC’s Joint Research Centre, the University of Reading, Stockholm
Environment Institute, Istanbul Technical University and University of
California-Berkeley. It built
extensively on the earlier Assessment by the United Nations Environment
Programme and World Meteorological Organization.
