The Arctic tundra is undergoing a dramatic transformation, driven by frequent wildfires that are turning it into a net source of carbon dioxide emissions after millennia of acting as a carbon…Continue readingArctic tundra is now emitting more carbon than it absorbs
Lying just off the Canadian mainland, Qikiqtaruk is a mass of sediment and permafrost piled up during the last ice age. Despite its small size, the island is packed with immense…Continue reading‘The land is tearing itself apart’: life on a collapsing Arctic isle
Seasonal change in the north is rapid and, for local people, summer marks a brief reprieve from months of bitter cold. But a heatwave that is currently hovering over the community…Continue reading‘It’s devastating’: summer in Canada’s Arctic region brings severe heatwaves
Dozens of rivers and streams in Alaska are turning rusty orange, a likely consequence of thawing permafrost, a new study finds. The Arctic is the fastest-warming region in the globe, and…Continue readingWarming climate is turning rivers rusty with toxic metals
Most people expect that if a system, like someone’s body, an ecosystem, or part of the climate system, becomes stressed, it’ll respond fairly predictably—double the pressure, double the impact, and so…Continue readingClimate tipping points are nearer than you think. Our new report warns of catastrophic risk.
Many of the gravest threats to humanity are drawing closer, as carbon pollution heats the planet to ever more dangerous levels, scientists have warned. Five important natural thresholds already risk being…Continue readingEarth on verge of five catastrophic climate tipping points, scientists warn
By Christoper Ketcham The Intergovernmental Panel on Climate Change has assumed Nordhaus is to be trusted. The integrated assessment models used at the IPCC are based on Nordhausian visions of adaptation…Continue readingWhen Idiot Savants Do Climate Economics
The Arctic is getting wetter and rainier Arctic precipitation is on the rise across all seasons, and these seasons are shifting. As sea ice rapidly declines, more open water is exposed,…Continue readingArctic Report Card
It was when the US Bureau of Indian Affairs built schools in Alaska, as part of an effort to assimilate Indigenous peoples into white culture, that the community was forced to…Continue readingAlaska Native community relocates as climate crisis ravages homes
More and more scientists are now admitting publicly that they are scared by the recent climate extremes, such as the floods in Pakistan and west Africa, the droughts and heatwaves in…Continue readingWhy scientists are using the word scary over the climate crisis
Global warming is responsible for bigger and bigger fires in Siberia, and in the decades ahead they could release huge amounts of carbon now trapped in the soil. Researchers fear a…Continue readingArctic fires could release catastrophic amounts of carbon dioxide
