Climate change caused by remote cities, says research

Scotsman: HEAT generated by large cities can alter the climate thousands of miles away, research suggests. The waste heat from buildings, factories and vehicles disrupts atmospheric systems that affect the weather over great distances, it is claimed. This is said to have a significant regional impact, raising or lowering seasonal temperatures by up to 1C. The effect may explain why some parts of the northern hemisphere are experiencing more winter warming than had been predicted by climate change...

Wasted heat from large cities affects temperatures in distant regions
2013-01-27 23:49:00| Climate Ark Climate Change & Global Warming Newsfeed
Independent: The waste heat generated by large cities can affect temperatures in areas hundreds of miles away by changing wind patterns in the upper atmosphere, a study has found. Scientists have estimated that the heat released into the atmosphere from buildings, cars and factories could play a significant role in the warming and the cooling of locations in other countries. Using computer models of how heat is transported around the globe, the study published in the journal Nature Climate Change says that...

Waste Heat From Cities May Be Altering Weather Patterns
2013-01-27 22:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Climate Central: The carbon dioxide that belches from tailpipes and smokestacks is a proven greenhouse gas that has been driving global temperatures more or less steadily upward over the past century. But the heat that leaks directly into the environment from hot exhaust pipes, boilers and chimneys has also contributed to temperature increases in some places, according to a study published Sunday in Nature Climate Change, especially in winter-- not directly, but rather because the waste heat may be altering the flow...

Heat from North American cities causing warmer winters, study finds
2013-01-27 20:30:00| Climate Ark Climate Change & Global Warming Newsfeed
Guardian: Those who wonder why large parts of North America seem to be skipping winter have a new answer in addition to climate change: big city life. A study, published in the journal Nature Climate Change, found that the heat thrown off by major metropolitan areas on America's east coast caused winter warming across large areas of North America, thousands of miles away from those cities. Winter warming was detected as far away as the Canadian prairies. In some remote areas, temperature rose by as much...

Big cities' heat can change temperatures a continent away: study
2013-01-27 19:02:00| Climate Ark Climate Change & Global Warming Newsfeed
Reuters: The energy big cities burn - mostly coal and oil to power buildings, cars and other devices - produces excess heat that can get into atmospheric currents and influence temperatures thousands of miles (km) away, a new study found. The so-called waste heat that leaks out of buildings, vehicles and other sources in major Northern Hemisphere cities makes winters warmer across huge swaths of northern Asia and northern North America, according to a report published on Sunday in the journal Nature Climate...
