An explosion of car use has made fast-growing Asian cities the epicentre of global air pollution and become, along with obesity, the world's fastest growing cause of death according to a major study of global diseases. In 2010, more than 2.1m people in Asia died prematurely from air pollution, mostly from the minute particles of diesel soot and … Read More
Women pregnant during heat waves face a higher risk of giving birth to babies with a rare defect causing blindness, according to new research. The study, surveying 15 years of birth defect records in New York state, offers troubling implications for a warmer climate. … Read More
For a couple of years now, climate scientists have agreed that to avoid the most serious consequences of global warming we need to cap the planet’s average temperature at no more than 2 degrees C (or 3.6°F) above where it stood in the 1800s. The temperature has already risen by about 1°C -- the longer we wait to rein in greenhouse-gas emissions, th… Read More
After another week of low rainfall and high temperatures in the Midwest and Great Plains, it is all but guaranteed that this year will end with more than half of the area in the lower 48 states still under drought conditions. Now, as the drought is poised to enter 2013, climatologists expect its impacts to worsen as it lasts through the winter. … Read More
While the total number of billion dollar natural disasters is down from 2011, when there were a record 14 such events, costing a total of about $60 billion, the economic losses this year are expected to exceed last year, largely due to the massive economic toll caused by Hurricane Sandy and the widespread drought… Read More
It was only a year ago that there was record flooding along the Mississippi River and many of its tributaries. Heavy rainfall combined with spring snowmelt to cause the mighty Mississippi to overflow its banks, damaging towns and farmland that line the waterway.… Read More
Summer and fall are hurricane season, but for the storms known as polar lows, prime time falls in the dead of winter, when frigid air blows off sea ice to collide with warmer, moister air in the North Atlantic. Polar lows are a lot smaller and weaker than hurricanes, they’re generally shorter-lived, and the only danger they generally pose is to… Read More
November was the 333rd month in a row with a global average surface temperature that was above the 20th century average, a clear sign of the warming trend that scientific evidence shows is very likely due in large part to manmade emissions of greenhouse gases, such as carbon dioxide.… Read More
