The Amazon is evolving, but not adapting as fast the climate is changing

Science
Nov. 8 (UPI) -- According to a new survey of the Amazon, the planet's largest forest is shifting its composition in response to climate change. Unfortunately, the research suggests the Amazon isn't evolving fast enough. The climate is changing faster than the Amazon can adapt. Most noticeably, scientists found moisture-loving tree species are dying off faster than they can be replaced by species that can withstand drier conditions. Droughts during the last decades have damaged large portions of the Amazon. "The ecosystem's response is lagging behind the rate of climate change," Adriane Esquivel Muelbert, geographer at the University of Leeds, said in a news release. "The data showed us that the droughts that hit the Amazon basin in the last decades had serious consequences for the makeup ...
Melting glacier in China draws tourists, climate worries

Melting glacier in China draws tourists, climate worries

Technology
The loud crack rang out from the fog above the Baishui No. 1 Glacier as a stone shard careened down the ice, flying past Chen Yanjun as he operated a GPS device. More projectiles were tumbling down the hulk of ice that scientists say is one of the world's fastest melting glaciers. "We should go," said the 30-year-old geologist. "The first rule is safety." Chen hiked away and onto a barren landscape once buried beneath the glacier. Now there is exposed rock littered with oxygen tanks discarded by tourists visiting the 15,000-foot (4,570-meter) -high blanket of ice in southern China. Millions of people each year are drawn to Baishui's frosty beauty on the southeastern edge of the Third Pole —— a region in Central Asia with the world's third-largest store of ice after Antarctica...
Climate change: Low cost, low energy cooling system shows promise

Climate change: Low cost, low energy cooling system shows promise

Science
Researchers in the US have scaled up a new low-cost system that could provide efficient cooling for homes while using very little electricity.The team has developed a roof-top sized array, built from a highly reflective material made from glass and polymers.In tests, the system kept water around 10C cooler than the ambient air when exposed to midday sunlight in summer. The approach could also be scaled up to cool power stations and data centres.The system is based around what's termed a cooling meta-material, which is essentially an engineered film not found in nature. Last year, researchers at CU Boulder in the US published research on the extraordinary properties of the new film, which reflects back almost all incoming light fr...
Anti-plastic focus 'dangerous distraction' from climate change

Anti-plastic focus 'dangerous distraction' from climate change

Science
The anti-plastic "fervour" sweeping across the UK is weakening the fight against climate change, the founder of an organic food company has said.Guy Singh-Watson, a prominent green entrepreneur and campaigner, said more focus should be put on cutting carbon. PM Theresa May has pledged to ban all avoidable plastic waste by 2042.Environmental experts have said that the anti-plastic movement showed the public could be "mobilised" for action on green issues.There has been growing awareness of the damage caused by single-use plastics after TV series Blue Planet II highlighted the issue last year.But Mr Singh-Watson, founder of Riverford Organic Farmers, which supplies about 47,000 boxes of vegetables to homes in the UK each week, sai...
Six climate questions for 'Green GB'

Six climate questions for 'Green GB'

Science
Scientists say we must keep global temperature rise under 1.5C - so what does that mean for the UK?Next week, ministers are likely to ask their advisers how Britain can reduce carbon emissions in line with that target.They’ve declared what they're calling Green GB Week – a celebration of the UK’s achievement as a world leader in tackling climate change whilst increasing the economy.But will they make the huge carbon cuts still needed on these six key issues? TransportOverall, the UK’s CO2 emissions have been falling, but transport emissions have gone UP by 4%. People are buying bigger cars after the Treasury removed the fuel duty incentive for low-pollution hybrids.Drivers have also turned away from diesel vehicles, which create f...
