The world's largest tropical desert, the Sahara, has suffered a catastrophic collapse of its wildlife populations, a new study has warned.
The study assessed 14 desert species and found that a shocking half of those are regionally extinct or confined to one percent or less of their historical range.
We assess climate impacts of global warming using ongoing observations and paleoclimate data. We use Earth’s measured energy imbalance, paleoclimate data, and simple representations of the global carbon cycle and temperature to define emission reductions needed to stabilize climate and avoid potentially disastrous impacts on today’s young people, future generations, and nature. A cumulative industrial-era limit of ~500 GtC fossil fuel emissions and 100 GtC storage in the biosphere and soil would keep climate close to the Holocene range to which humanity and other species are adapted.
The year 2013 is currently on course to be among the top ten warmest years since modern records began in 1850, according to this WMO provisional statement on status of the climate.
Scientists have identified regions in Antarctica that could store information about Earth’s climate and greenhouse gases dating back to 1.5 million years, twice as old as ice core drilled to date.
This new scientific report released by World Bank shows that moving rapidly to reduce pollutants such as methane and black carbon, could slow warming in critical snow and ice-covered regions while benefitting human welfare.
"Climate Change 2013: The Physical Science Basis" is the contribution of Working Group I to the Fifth Assessment Report of the Intergovernmental Panel on Climate Change. This comprehensive assessment of
The opening in the earth's stratospheric ozone layer over Antarctica is closing slowly and should recover completely in the later half of this century, though its effect on global climate change is
Analysis of an Antarctic ice core has revealed that warming in the frozen continent began about 22,000 years ago, a few thousand years earlier than suggested by earlier records.
