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…

Mass Extinctions Cause Evolutionary Bottlenecks

Science World Report, Aug 14, 2013: Extinctions are occurring at a phenomenal rate these days. As our climate changes and environments are altered, species are disappearing from our planet. Now, scientists are examining mass extinctions more closely. They’ve discovered how after these events in the past, species and ecosystems managed to recover in the aftermath. About…

Climate Crisis as a Political Issue

John Hofmeister discusses with Greg Dalton how the global climate crisis is a problem that needs political help to be solved. Hofmeister states that since the political system runs on 2 year intervals, it is difficult to solve the climate crisis our planet is suffering from.

Each degree of global warming might ultimately raise global sea levels by more than 2 meters

By PIK: 07/15/2013 – Greenhouse gases emitted today will cause sea level to rise for centuries to come. Each degree of global warming is likely to raise sea level by more than 2 meters in the future, a study now published in the Proceedings of the National Academy of Sciences shows. While thermal expansion of…

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. http://www.nasa.gov/mission_pages/fires/main/index.html

NASA: Potential Evaporation in North America Through 2100 (August 2013 in HD)

Published on Aug 9, 2013 by NASA: This animation shows the projected increase in potential evaporation through the year 2100, relative to 1980, based on the combined results of multiple climate models. The maximum increase across North America is about 1 mm/day by 2100. This concept, potential evaporation, is a measure of drying potential or…
