Scientists at the University of Hawaiʻi at Mānoa have projected an increased frequency of heavy rainfall events, but a decrease in rainfall intensity during the next 30 years (2011–2040) for the southern shoreline of Oʻahu, according to a recent study published in the Journal of Geophysical Research.

Chase Norton, a Meteorology Research Assistant at the School of Ocean and Earth Science and Technology (SOEST) at UH Mānoa, and colleagues (Professors Pao-Shin Chu and Thomas Schroeder) used a statistical model; rainfall data from rainfall gauges on Oahu, Hawaiʻi; and a suite of General Circulation Models (GCMs) from the Intergovernmental Panel on Climate Change (IPCC) to project future patterns of heavy rainfall events on Oʻahu. GCMs play a pivotal role in the understanding of climate change and associated local changes in weather. (more…)

Thawing Permafrost Could Release Vast Amounts of Carbon and Accelerate Climate Change by the end of this Century

*New computer modeling study, led by a Berkeley Lab scientist, could help revise understanding of permafrost’s role in global warming*

Billions of tons of carbon trapped in high-latitude permafrost may be released into the atmosphere by the end of this century as the Earth’s climate changes, further accelerating global warming, a new computer modeling study indicates.

The study also found that soil in high-latitude regions could shift from being a sink to a source of carbon dioxide by the end of the 21^st century as the soil warms in response to climate change. (more…)

A leading academic at the University of Exeter has played a central role in compiling a report which could be vital for global efforts to tackle climate change.

Professor Catherine Mitchell, part of the University’s Energy Policy Group based in Cornwall, was one of only two experts from the UK to contribute to the ‘Special Report on Renewable Energy Sources and Climate Change Mitigation’ (SRREN). (more…)
