Climate scientists close to forecasting near-term global warming impacts

Climate scientists close to forecasting near-term global warming impacts

Science
Jan. 22 (UPI) -- One of the biggest challenges of modeling climate change is making near-term and localized predictions. But according to a new study, published this week in the journal Nature Climate Change, scientists are finally starting to accurately simulate the influence of long-term climate change on short-term seasonal forecasts. "There is a lot of work still to do, but just as weather forecasts became a regular operational activity in the 20th century, we are now approaching a similar point for near term climate predictions and these are now being made at a number of scientific institutes worldwide," Adam Scaife, professor at the University of Exeter and a climate scientist with the Met Office, said in a news release. By building climate models from the ground up, using real-time...
Climate change: Huge costs of warming impacts in 2018

Climate change: Huge costs of warming impacts in 2018

Science
Extreme weather events linked to climate change cost thousands of lives and caused huge damage throughout the world in 2018, say Christian Aid.The charity's report identified ten events that cost more than $ 1bn each, with four costing more than $ 7bn each.Scientists have shown that the chances of heat waves in Europe were influenced directly by human-related warming.Other events, say the authors, are due to shifts in weather patterns, said to be a consequence of climate change.According to the report the most financially costly disasters linked to rising temperatures were Hurricanes Florence and Michael, with costs said to be around $ 17bn for the former, and $ 15bn for the latter. Research published at the time showed that the ...
Climate change: Failure to tackle warming 'suicidal'

Climate change: Failure to tackle warming 'suicidal'

Science
The UN secretary-general has warned negotiators at a major meeting that failing to increase efforts on climate change would be "not only immoral but suicidal" for the planet. Antonio Guterres has flown back to Poland to try and push COP24 to a successful conclusion. At the UN talks, a group of countries have said they will enhance their climate plans before 2020.The EU and others say they are responding to the urgency of science.Some observers believe that the return of Mr Guterres to these talks is a sign that significant progress is not being made. In his remarks to the conference, he underlined that fact, imploring the delegates to speed up the pace of negotiations and to be open to compromise.He said that key political issues...
Scary warming at poles showing up at weird times, places

Scary warming at poles showing up at weird times, places

Technology
Scientists are seeing surprising melting in Earth's polar regions at times they don't expect, like winter, and in places they don't expect, like eastern Antarctica. New studies and reports issued this week at a major Earth sciences conference paint one of the bleakest pictures yet of dramatic warming in the Arctic and Antarctica. Alaskan scientists described to The Associated Press Tuesday never-before-seen melting and odd winter problems, including permafrost that never refroze this past winter and wildlife die-offs. The National Oceanic and Atmospheric Administration Tuesday released its annual Arctic report card, detailing the second warmest year on record in the Arctic and problems, including record low winter sea ice in parts of the region, increased toxic algal blooms, which are no...
Climate change: Warming made UK heatwave 30 times more likely

Climate change: Warming made UK heatwave 30 times more likely

Science
Climate change has significantly boosted the chances of having summer heatwaves in the UK.A Met Office study says that the record-breaking heat seen in 2018 was made about 30 times more likely because of emissions from human activity. Without warming the odds of a UK heatwave in any given year were less than half a percent. But a changing climate means this has risen to 12%, or about once every eight years. The blazing summer of 2018 was the joint warmest for the UK,It tied with 1976, 2003 and 2006 for being the highest since records began in 1910.The steep temperatures that sustained across most parts of the UK, peaked on July 27 when 35.6C was recorded at Felsham in Suffolk. Now researchers have analysed the observed data using...
