by Marion THIBAUT Agence France Presse Churchill, Canada (AFP)– Sprawled on rocky ground far from sea ice, a lone Canadian polar bear sits under a dazzling sun, his white fur utterly useless as camouflage. It’s mid-summer on the shores of Hudson Bay and life for the enormous male has been moving in slow motion, far from the prey that keeps him alive: seals. This is a critical time for the region’s polar bears. Every year […]
SINGAPORE, Singapore (AFP) — Singapore said Monday it would impose a carbon tax from next year to cut its greenhouse gas emissions and make companies more competitive as global agreements on climate change take effect. Finance Minister Heng Swee Keat said the tax would be levied on all facilities producing 25,000 tons or more of greenhouse gas emissions a year. The tax, to be applied to all sectors, will be Sg$5.0 ($3.8) per ton of […]
PARIS, France (AFP) — Mammals and birds stand the best chance of all animals of surviving Earth’s rapidly changing climate, researchers said Monday. An analysis of how nearly 11,5000 species fared over 270 million years of hot-and-cold fluctuations showed that warm-blooded creatures cope better with change than reptiles and amphibians, a team reported in the journal Nature Ecology & Evolution. “We see that mammals and birds are better able to stretch out and extend their […]
by Marlowe HOOD Agence France Presse PARIS, France (AFP) — Geoengineering schemes designed to deflect some of the Sun’s planet-warming rays would backfire if suddenly discontinued, wiping out species and entire ecosystems, a study published Monday warns. “Rapid warming after stopping geoengineering would be a huge threat to the natural environment and biodiversity,” said co-author Alan Robock, a professor at Rutgers University in New Jersey. Half-a-century’s worth of warming could rebound in a handful of […]
by Marlowe Hood Agence France Presse PARIS, France (AFP) — Earth’s surface will almost certainly not warm up four or five degrees Celsius by 2100, according to a study released Wednesday which, if correct, voids worst-case UN climate change predictions. A revised calculation of how greenhouse gases drive up the planet’s temperature reduces the range of possible end-of-century outcomes by more than half, researchers said in the report, published in the journal Nature. “Our study […]
by Marlowe HOOD Agence France Presse PARIS, France (AFP) — Climate change will sharply boost the frequency of lethal heatwaves even if humanity caps global warming at two degrees Celsius (3.6 degrees Fahrenheit), the core goal of the Paris Agreement, scientists said Monday. Fulfilling that 196-nation pledge would, by 2100, still leave nearly half the world’s population exposed at least once a year to bouts of heat and humidity that have proven deadly in the […]
PARIS, France (AFP) — The world added a record 138.5 gigawatts of renewable power capacity in 2016 despite a 23 percent drop in investment, reflecting the falling cost of clean energy, the United Nations announced Thursday. The new energy — mainly from wind and solar installations, but not including large hydro projects — was up eight percent from the previous year, on global investment of $242 billion (227 billion euros). Investment in fossil fuel-based energy […]
by Maria ANTONOVA MOSCOW, Russia (AFP) — Russia’s practice of leaving massive wildfires to burn out of control in sprawling stretches of Siberia puts at risk a key global resource for absorbing climate-warming emissions: its trees. The blazes are consuming millions of hectares of pristine Boreal forests in Russia, which are second only to the world’s tropical jungles in capturing planet-warming carbon emissions. At the same time, the drier and harsher conditions associated with a […]
