Abrupt Climate Change In The Arctic (And Beyond) An Update

AGU Fall Meeting 2013: Our understanding of future Arctic change is informed by the history of past changes, which often have been both large and abrupt. The well-known ice-age events such as the Younger Dryas show how sea-ice changes can amplify forcing to produce very large responses, with wintertime sea ice especially important. These changes…

Global Warming Underestimated by Half

Uploaded on YouTube Aug 21, 2013: Coverage bias in the HadCRUT4 temperature series and its impact on recent temperature trends. Cowtan & Way (2013) Stefan Rahmstorf at RealClimate: A new study by British and Canadian researchers shows that the global temperature rise of the past 15 years has been greatly underestimated. The reason is the data gaps in…

NASA: IPCC Projections of Temperature and Precipitation in the 21st Century

Published on YouTube Sep 27, 2013: New data visualizations from the NASA Center for Climate Simulation and NASA’s Scientific Visualization Studio show how climate models — those used in the new report from the United Nations’ Intergovernmental Panel on Climate Change (IPCC) — estimate how temperature and precipitation patterns could change throughout the 21st century.…

Climate Extremes and the Carbon Cycle

A new study (doi:10.1038/nature12350) published in nature, explores the impacts of extreme weather events on the carbon cycle. By Bobby Magill / Wunderground, published: August 15, 2013: Devastating drought in the Southwest, unprecedented wildfire activity, scorching heat waves and other extreme weather are often cited as signs of a changing climate. But what if those extreme…

Heat Waves to Become Much More Frequent and Severe

Science Daily Aug. 15, 2013 — Climate change is set to trigger more frequent and severe heat waves in the next 30 years regardless of the amount of carbon dioxide (CO2) we emit into the atmosphere, a new study has shown. Extreme heat waves such as those that hit the US in 2012 and Australia…

Heat stress reduces labor capacity under climate warming

NOAA study about heat stress and projected labor impact: John P. Dunne, Ronald J. Stouffer, and Jasmin G. John. Journal: Nature Climate Change. DOI: 10.1038/nclimate1827 Key Findings Due to projected increases in temperature and water vapor in the atmosphere: Labor capacity losses related to heat stress are projected to double globally by 2050 with a warming climate. Global…

NASA: Wildfires, Smog – Particulate Matter Will Only Get Worse (August 2013)


August 10, 2013 – NASA Research is showing due to the increase in the earth’s temperature, we can expect to see more wildfires, and fires in areas that normally don’t see fires. NASA scientists talked to The Weather Channel about the latest research.

NASA: The Future of Fires in Perspective to Future Emissions Scenario’s (August 2013)

Published on Aug 8, 2013 by NASA: With climate change, certain areas of the United States, like the great Plains and Upper Midwest, will be at a greater risk of burning by the end of the 21st-century. Areas like the Mountain West that are prone to burning now will see even more fires than they…

NASA: Projected U.S. Temperature Changes by 2100

NASA: The average temperature across the continental U.S. could be 8 degrees Fahrenheit warmer by the end of the 21st century under a climate scenario in which concentrations of the greenhouse gas carbon dioxide rise to 800 parts per million. Current concentrations stand at 400 parts per million, and are rising faster than at any…

Most Comprehensive Paleoclimate Reconstruction Confirms Hockey Stick

By Stefan Rahmstorf via Scilogs The past 2000 years of climate change have now been reconstructed in more detail than ever before by the PAGES 2k project. The results reveal interesting regional differences between the different continents, but also important common trends. The global average of the new reconstruction looks like a twin of the…

May 2013 Earth’s 3rd Warmest May; Central European Floods Cost $22 Billion

By Jeff Masters / Wunderground: May 2013 was the globe’s 3rd warmest May since records began in 1880, according to NOAA’s National Climatic Data Center (NCDC). NASA rated it the 10th warmest May on record. The year-to-date period of January – May has been the 8th warmest such period on record. May 2013 global land…

Heatwaves blamed on Global Warming

Unusually high frequency points to human influence | NASA climatologist James Hansen made headlines during the US heatwave of 1988, declaring in testimony to Congress and during interviews on prime-time television that a build-up of greenhouse gases was increasing the probability of weather extremes. Now, as much of the United States sizzles through another torrid…

Central West Antarctica among the most rapidly warming regions on Earth

There is clear evidence that the West Antarctic Ice Sheet is contributing to sea-level rise. In contrast, West Antarctic temperature changes in recent decades remain uncertain. West Antarctica has probably warmed since the 1950s, but there is disagreement regarding the magnitude, seasonality and spatial extent of this warming. This is primarily because long-term near-surface temperature…
