Heatwaves projected to double by 2020, study says
2013-08-15 14:28:00| Climate Ark Climate Change & Global Warming Newsfeed
Reuters: The areas of the world hit by heatwaves are set to double in size by 2020 and continue to grow in coming decades, as heat-trapping greenhouse gases warm the global climate, scientists in Germany and Spain said on Thursday. The projections, based on new computer models and reviewing what the scientists said was an "exceptional number of extreme heatwaves" in the past decade, are more alarming than the conclusions of the U.N. panel of climate scientists last year. That report by the Intergovernmental...

Heatwaves will make crops produce smaller grains

Guardian: "The wheat is usually green at this time, but its already gone brown," says Laurence Matthews, overlooking a bone-dry and dusty field on his 3,000-acre farm near Dorking in Surrey. "It's like a tinderbox: there's a real risk of fire." The summer heatwave is having a dramatic effect on his crops. "Without water, the plants just shut down," he says. But it is the twists and turns of increasingly erratic weather that is making farming more difficult, Matthews says. "In spring 2012, it was unbelievably...

Global warming drives more nighttime heatwaves
2013-07-23 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Summit Voice: A trend of more frequent nighttime heatwaves in the Pacific Northwest may not portend killer temperatures and withering crops, but it is another sign that global warming will have a profound effect on regional climate and weather. Scientists with the Oregon Climate Service at Oregon State University documented 15 examples of nighttime heat waves from 1901 through 2009. Ten of them have occurred since 1990 and five were during a four-year period from 2006-09. The research shows that the region...

Gimme swelter: we explain the UK and US heatwaves
2013-07-20 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
New Scientist: After the cold, the heat. High pressure spreading across the UK from Siberia last spring brought record cold temperatures. Now more high pressure, this time from the tropical Atlantic, is bringing a sweltering heatwave. These high-pressure zones are blocking the jet stream which usually brings the country's normal changeable weather. "Blocking highs" are an increasing theme of North American weather reports too, bringing concern of a long-term shift. New Scientist looks at the issues. What's going...

Pakistan can expect worse heatwaves to come, meteorologists warn
2013-06-17 10:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Guardian: Near-record temperatures in Pakistan have claimed hundreds of lives and devastated crops in the third major heatwave in four years. But as temperatures on Friday dipped to under 38C (100F), signalling the end of nearly four weeks of blistering heat, leading meteorologists warned that the country could expect longer, more intense and more frequent events in future. Qamar-uz-Zaman Chaudhry, a vice-president of the World Meteorological Organisation (WMO) and former director of Pakistan's Met Office,...
