Climate change: Warming to drive ‘robust increase’ in UK flooding

Climate change: Warming to drive ‘robust increase’ in UK flooding

Science
Coastal areas in the UK and Northern Europe will experience an increase in "compound flooding" in coming decades say researchers. These events, where storm surges and heavy rainfall combine, will become more common thanks to rising global temperatures. Devon, Cornwall and the Bristol channel may become "hotspots" with events seen more than once every six years. The study is published in the journal Science Advances. Researchers say that floods on the Avon in Bristol in 2014 and in Ravenna in Italy in 2015 are both good examples of compound events that have caused significant losses to people and property.These events are marked by a combination of storm surge and heavy rainfall, sometimes driven by the same low pressure system. Storm surges can be made wo...
Climate change: Electrical industry’s ‘dirty secret’ boosts warming

Climate change: Electrical industry’s ‘dirty secret’ boosts warming

World
It's the most powerful greenhouse gas known to humanity, and emissions have risen rapidly in recent years, the BBC has learned. Sulphur hexafluoride, or SF6, is widely used in the electrical industry to prevent short circuits and accidents. But leaks of the little-known gas in the UK and the rest of the EU in 2017 were the equivalent of putting an extra 1.3 million cars on the road. Levels are rising as an unintended consequence of the green energy boom.Cheap and non-flammable, SF6 is a colourless, odourless, synthetic gas. It makes a hugely effective insulating material for medium and high-voltage electrical installations. It is widely used across the industry, from large power stations to wind turbines to electrical sub-station...
Wind shifts caused by human-induced global warming cause of West Antarctic’s melting ice

Wind shifts caused by human-induced global warming cause of West Antarctic’s melting ice

Science
Aug. 16 (UPI) -- Human-caused climate change has triggered wind shifts in Antarctica, according to a new study, driving accelerated melting across the continent's west coast. The research -- published this week in the journal Nature Geoscience -- is the first to draw a direct link between human-induced global warming and Western Antarctica's rapidly melting glaciers. Scientists have previously shown that influxes of warm coastal water are driving the loss of ice among Western Antarctica's largest glaciers. Previous research has also shown that variable wind patterns dictate the movement of warm and cold water masses. For the latest study, scientists used satellite observations and climate model simulations to analyze how these wind patterns have changed since 1920. The data showed the wi...
Scientists consider ‘human-made volcano’ to slow global warming

Scientists consider ‘human-made volcano’ to slow global warming

Science
Aug. 5 (UPI) -- Throughout Earth's history, volcanic eruptions have periodically cooled Earth. Though most eruptions aren't big enough to influence global climate patterns, especially large eruptions can have a global impact. When a large amount of ash is spewed into the atmosphere, the particles reflect the sun's rays back toward space, lowering the temperature on Earth. In a new paper, published this week in the journal Geophysical Research Letters, scientists considered the possibility of replicating the cooling effects of a volcanic eruption -- a "human-made volcano" to combat climate change. "Nobody likes the idea of intentionally tinkering with our climate system at global scale," Ken Caldeira, researcher at the Carnegie Institution for Science, said in a news release. "Even if we ...
