by Marlowe HOOD Agence France-Presse PARIS, France (AFP) — Even if humanity stopped emitting greenhouse gases tomorrow, Earth will warm for centuries to come and oceans will rise by metres, according to a controversial modelling study published Thursday. Natural drivers of global warming — more heat-trapping clouds, thawing permafrost, and shrinking sea ice — already set in motion by carbon pollution will take on their own momentum, researchers from Norway reported in the Nature journal […]
by Amélie BOTTOLLIER-DEPOIS Agence France Presse PARIS, France (AFP) — Long-dormant viruses brought back to life; the resurgence of deadly and disfiguring smallpox; a dengue or zika “season” in Europe. These could be disaster movie storylines, but they are also serious and increasingly plausible scenarios of epidemics unleashed by global warming, scientists say. The COVID-19 pandemic that has swept the globe and claimed over 760,000 lives so far almost certainly came from a wild bat, […]
by Maria ANTONOVA Agence France-Presse MOSCOW, Russia (AFP) — An unprecedented fuel spill that has polluted huge stretches of Arctic rivers was caused by melting permafrost, Russian officials said Friday, ordering a review of infrastructure in vulnerable zones. The spill — which has coloured remote tundra waterways with bright red patches visible from space — has highlighted the danger of climate change for Russia as areas locked by permafrost for centuries thaw amid warmer temperatures. […]
by Marlowe HOOD PARIS, France (AFP) — Permafrost in Canada, Alaska, and Siberia is abruptly crumbling in ways that could release large stores of greenhouse gases more quickly than anticipated, researchers have warned. Scientists have long fretted that climate change — which has heated the Arctic and subarctic regions at double the global rate — will release planet-warming CO2 and methane that has remained safely locked inside Earth’s frozen landscapes for millennia. It was assumed […]
TOKYO, Japan (AFP) — A warming climate is thawing permafrost and up to 70 percent of infrastructure in the Arctic region is at risk, including key oil and gas fields, a new study said Wednesday. Researchers used detailed information on infrastructure across the Northern Hemisphere permafrost zone to model with unprecedented detail just how many buildings, roads, railways and other construction could be at risk by 2050. “The magnitude of the threat was in a […]
by Maria ANTONOVA Agence France-Presse YAKUTSK, Russia (AFP) — Eduard Romanov points to a spot on a block of flats where a major supporting beam has sagged and begun to crack, destabilizing the nine storeys of apartments above. In Russia’s Siberian city of Yakutsk, one of the coldest on Earth, climate change is causing dangerous melting of the frozen ground, or permafrost, on which the buildings stand. “Since the year before last, the building has […]
by Patrick GALEY Agence France-Presse Global targets aimed at warding off runaway planetary warming could be breached sooner than expected, experts warned Monday, as gases released by melting permafrost threaten to undermine human efforts to avert climate disaster. Under the current rescue plan, outlined in the 2015 Paris climate treaty, countries have agreed to limit global temperature rises to “well below” two degrees Celsius, and 1.5C if deemed possible. That course of action assumes that […]
by Marlowe HOOD PARIS, France (AFP) — Frozen, sub-Arctic wastelands loaded with planet-heating greenhouse gases are more susceptible to global warming than previously understood, scientists warned on Monday. Even stabilising the world’s climate at two degrees Celsius (3.6 degrees Fahrenheit) above pre-industrial levels — the daunting goal laid down in the 196-nation Paris Agreement — would melt more than 40 percent of permafrost, or an area nearly twice the size of India, they reported in […]
