A recent heatwave in Siberia’s frozen wastes has resulted in outbreaks of deadly anthrax and a series of violent explosions

July 20, 2017 — Strange things have been happening in the frozen tundra of northern Siberia. Last August a boy died of anthrax in the remote Yamal Peninsula, and 20 other infected people were treated Continue reading All hell breaks loose as the tundra thaws

Multi-million dollar upgrade planned to secure ‘failsafe’ Arctic seed vault

Improvements aim to ensure the vault’s role as an impregnable deep freeze for the world’s most precious food seeds after a recent flooding by melting permafrost

June 13, 2017 — The Global Seed Vault, built in the Arctic as an impregnable deep freeze for the world’s most precious food seeds, is to undergo a multi-million dollar upgrade after water from melting permafrost flooded its access tunnel. Continue reading Multi-million dollar upgrade planned to secure ‘failsafe’ Arctic seed vault

No seeds were lost but the ability of the rock vault to provide failsafe protection against all disasters is now threatened by climate change

May 19, 2017 — It was designed as an impregnable deep-freeze to protect the world’s most precious seeds from any global disaster and ensure humanity’s food supply forever. But the Global Seed Continue reading Arctic stronghold of world’s seeds flooded after permafrost melts

Northern tundra’s autumn carbon dioxide emissions increased 70% between 1975 and 2015, researchers find, blaming warming temperatures

May 8, 2017 — Alaska’s soils are taking far longer to freeze over as winter approaches than in previous decades, resulting in a surge in carbon dioxide emissions that could portend a much faster rate of Continue reading Slow-freezing Alaska soil driving surge in carbon dioxide emissions

Global warming scientists learn lessons from the pause that never was

New study finds there never was an unexpected lull in climate change but says the science community needs to communicate better

May 4, 2017 — People don’t talk about how global warming has stopped, paused or slowed down all that much any more – three consecutive hottest years on record will tend to do that to a flaky meme. Continue reading Global warming scientists learn lessons from the pause that never was
