Global warming will bring more U.S. lightning strikes
2014-11-14 15:50:00| Climate Ark Climate Change & Global Warming Newsfeed
LiveScience: A 50 percent increase in the number of lightning strikes within the United States can be expected by 2100 if temperatures continue to rise due to greenhouse gas emissions, a new study claims. Researchers found a 12 percent increase in lightning activity for every 1.8 degrees Fahrenheit (1 degree Celsius) of warming in the atmosphere, according to the study, published on Nov. 13 in the journal Science. Without emissions cuts, scientists expect this century to end with global temperatures that are...

Study: Global warming worsening watery dead zones
2014-11-10 17:59:00| Climate Ark Climate Change & Global Warming Newsfeed
Associated Press: Global warming is likely playing a bigger role than previously thought in dead zones in oceans, lakes and rivers around the world and it's only going to get worse, according to a new study. Dead zones occur when fertilizer runoff clogs waterways with nutrients, such as nitrogen and phosphorous. That leads to an explosion of microbes that consumes oxygen and leaves the water depleted of oxygen, harming marine life. Scientists have long known that warmer water increases this problem, but a new...

Fight fiercely, Harvard, against global warming, alumnus says
2014-11-05 23:08:00| Climate Ark Climate Change & Global Warming Newsfeed
Sydney Morning Herald: 'Fight fiercely, Harvard', a favorite college's song, doesn't seem to apply to climate change, an alumnus says. More than 40 years ago, as a Harvard sophomore, I sat in the classroom of Professor Roger Revelle, who was teaching a course on human population. We learned about Malthus, Norman Borlaug and the green revolution. Revelle, in his heavily stained necktie, would entertain us with mental calculations he'd performed while taking a shower earlier in the morning. Over the course of the semester,...

Climate change: no quick fix for global warming 'without cutting down carbon emissions'
2014-11-05 15:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Business Times: Short-term fixing of the global climate will not help, says a new interdisciplinary study by showing how long-term emissions of carbon dioxide and short-lived climate pollutants like methane and sulphur dioxide are related. Soot particles, methane and fluorocarbons originating from fossil fuels, coal mines, cows and diesel engines are called short-lived climate forcers (SLCF) due to their brief lifetime of a few days to a decade. On the other hand carbon dioxide lasts thousands of years in...
Global warming will make our winters colder
2014-10-27 01:32:00| Climate Ark Climate Change & Global Warming Newsfeed
Independent: Britain can expect twice as many severe winters as usual over the coming decades, according to a study supporting the counterintuitive idea that global warming could lead to colder weather in some parts of the world. Climate scientists believe they have found evidence to suggest that the loss of floating Arctic sea ice in the Barents and Kara seas north of Scandinavia can affect the global circulation of air currents and lead to bitterly cold winds blowing for extended periods in winter over Central...
