Heat wave, air pollution, mortality, and adaptation, a quick look

While summer currently gears up, during exceptional continued record global warming, temperatures are set to reach the highest so far this summer in many parts of the northern hemisphere – within the next few day’s (Germany, U.S. etc). Here we look at the past 2003 heat wave and what attributed to excess deaths during that extensive heat period…

AGU 2015: The impacts of heat stress on densely populated regions in the 21st century

Globally, heat kills more people than any other weather-related event. With temperatures and humidity expected to increase in the coming decades, heat stress is projected to have increasingly severe impacts on many regions of the world. Here, researchers estimate the global exposure to fatal heat stress throughout the 21st century and its effects on human…

Climate Effects on Human Evolution

This article explores the hypothesis that key human adaptations evolved in response to environmental instability.  This idea was developed during research conducted by the Smithsonian’s Human Origins Program. Natural selection was not always a matter of ‘survival of the fittest’ but also survival of those most adaptable to changing surroundings. By the Smithonian  Background Paleoanthropologists – scientists who…

Australia: Top temperature forecast to reach 46C | Heat stress | Power outages | Wildfires

Adelaide could break its 75-year-record for its hottest day – a searing 46.1C in January 1939 – after its warmest night in five years. The mercury only dropped to 29.9C just before 6:30am, with the temperature still above 35C at 2:00am. Acting regional director at the Bureau of Meteorology, John Nairne, says a new record…

Australia’s 2014 Heat Wave Picks Up Where 2013 Left Off

The U.S. may just be climbing out of the freezer, but Australia has been sweating through a major heat wave to start the year. Heat records fell across a large part of the country in the first week of the New Year. The warm weather is currently centered over sparsely populated Western Australia, but it could hit major population centers…

2013 was hottest year on record in Australia

Australia has just sweltered through its hottest year on record, according to the Bureau of Meteorology. Average temperatures were 1.20 degrees Celsius above the long-term average of 21.8C, breaking the previous record set in 2005 by 0.17C. Professor Karoly: “In the model experiments, it is not possible to reach such a temperature record due to natural climate…

Australia record-breaking heat wave bushfires rage as temperatures hit 54C

Published on YouTube Jan 2, 2014 Notice how the above video is not mentioning: – Record breaking temperatures were set – Australia just had the warmest Spring on record – The current heat wave is the largest ever recorded – 2013 was the warmest year on record John Nairn from the weather bureau says several…

Climate Change, Clashes and Riots

Are recent clashes and riots affected by climate change? And if so to what extent? An exhaustive study of a wide range of conflicts over thousands of years has found that rising temperatures are inevitably linked to an increase in violence. Stand by for more violence. As planetary temperatures rise, so does the likelihood of…

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 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.
