Military: Climate Strategy Vital, Not Political Chicken Game

A panel of extraordinary military leaders—16 men and women generals and admirals, including prior commanders, commandants, and members of the Joint Chiefs of Staff—came to a pretty devastating conclusion recently about climate strategy. The Military Advisory Board of the Center for Naval Analyses, a 70-year-old federally funded think tank, says that current actions by the […]

The Arctic's 'Ticking Carbon Bomb' – State of Thawing Permafrost: 'Actual Situation is Worse'

New analyses of stored carbon in permafrost presented at last week’s annual American Geophysical Union (AGU) meeting are causing greater concern amongst climate scientists. One of the new analyses (Hugelius et al) of soil carbon in permafrost utilized data from both new field work and archival records, totaling over 400 sites. The analysis estimates that

Extreme Ice Sheet Melting Does Not Need Extreme Heat

New research has provided evidence to suggest that massive melting of ice sheets like the Greenland ice sheet does not need corresponding record temperature highs, rather, just persistent warm weather over several years. Such results suggest that glaciers and ice sheets could undergo a self-amplifying cycle of melting and warming simply if there is persistently

Climate Variation During Greenhouse Conditions

Researchers from the National Oceanography Centre in Southampton, England, have concluded that man-made global warming would probably not greatly change the influence had on the environment by inter-annual climate instances such as El Niño – Southern Oscillation (ENSO) or the Arctic Oscillation/ North Atlantic Oscillation (AO/ NAO). “Even in the warm Cretaceous period, the patterns

Link Found Between Ancient Climate Change and Mass Extinction

New research led by researchers at the California Institute of Technology, Caltech, have discovered new details that support the idea that the mass extinction that took place approximately 450 million years ago, known as the Late Ordovician mass extinction, was linked to a cooling climate. During the Late Ordovician mass extinction more than 75 percent

Is Our Hot Past Representative of Our Future

An analysis by National Center for Atmospheric Research (NCAR) scientist Jeffrey Kiehl published in the most recent edition of the journal Science in the ‘Perspectives’ section has concluded that the sheer scale of climate change during Earth’s ancient history points to temperatures rising far more than expected in Earth’s immediate future. Kiehl brought together several

Gradual Warming Not Entirely Responsible for Greenland Icesheet Flow

A new study to come out of the University of British Columbia has shown that sudden changes in the amount of meltwater contributes more to the acceleration, and thus the eventual loss, of the Greenland ice sheet than the gradual increase of temperature, reversing previously thought views on the matter. “The conventional view has been
