United Kingdom: On Thames, centuries of history tell a less apocalyptic flood story
2014-02-16 01:16:00| Climate Ark Climate Change & Global Warming Newsfeed
Guardian: A British fixation with the weather seems to link readily with a pessimistic view of our vulnerability to flooding. This has been underlined through an outstandingly wet winter, with often protracted floods. For those directly affected, in Somerset especially, this has been a harrowing experience, and the impact on transport, agriculture and commerce has been severe. Many believe that the cluster of major floods in the early years of the 21st century herald much worse as global temperatures continue...

After Four Centuries, Southwest US Irrigation System Faces Decline
2014-02-14 02:31:00| Climate Ark Climate Change & Global Warming Newsfeed
Nature World: Dwindling snowmelt runoff, combined with social and economic factors favoring modernism over tradition, has lead to the decline of communal irrigation systems known as acequias that have sustained farming villages in the arid southerwestern US for centuries, according to a Dartmouth College study. The study, which appears in the journal of Global Environmental Change, reflects similar changes seen around the world in which isolated communities become integrated into a larger economy. This integration...

Ocean crust could store many centuries industrial carbon dioxide
2013-12-04 16:31:00| Climate Ark Climate Change & Global Warming Newsfeed
ScienceDaily: Researchers from the University of Southampton have identified regions beneath the oceans where the igneous rocks of the upper ocean crust could safely store very large volumes of carbon dioxide. The burning of fossil fuels such as coal, oil, and natural gas has led to dramatically increasing concentrations of CO2 in the atmosphere causing climate change and ocean acidification. Although technologies are being developed to capture CO2 at major sources such as power stations, this will only avoid...

Carbon in atmosphere 'could warm planet for centuries'
2013-11-24 19:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Telegraph: Carbon dioxide which is already in our atmosphere could continue warming the planet for centuries even if new emissions were entirely halted, scientists claim. A new analysis of future carbon emission scenarios found that it may take significantly fewer emissions for global temperatures to reach unsafe levels than previously thought. Carbon dioxide, the most important greenhouse gas, has long-term effects because it can remain in the atmosphere for centuries after it is emitted. To understand...

Solar activity heads for lowest low in four centuries
2013-11-01 19:45:00| Climate Ark Climate Change & Global Warming Newsfeed
New Scientist: The sun's activity is in free fall, according to a leading space physicist. But don't expect a little ice age. "Solar activity is declining very fast at the moment," Mike Lockwood, professor of space environmental physics at Reading University, UK, told New Scientist. "We estimate faster than at any time in the last 9300 years." Lockwood and his colleagues are reassessing the chances of this decline continuing over decades to become the first "grand solar minimum" for four centuries. During a...
