If climate heating continues apace and the planet goes on warming, then up to a third of Antarctica’s ice shelf could tip into the sea. And tip is the operative word, according to a separate study: at least one Antarctic glacier could be about to tip into rapid and irreversible retreat if temperatures go on rising. And rise they could: evidence from the past in a third research programme confirms that at the end of the last Ice Age, Greenland’s temperature rose by somewhere between 5°C and 16°C in just decades, in line with a cascade of climate change events. And ominously a fourth study of climate change 14,600 years ago confirmed that as the ice retreated, sea levels rose at 10 times the current rate, to 3.6 metres in just a century, and up to 18 metres in a 500-year sequence.

In the picturesque mountain village of Lete, flanked by the soaring Himalayan peaks of Annapurna and Dhaulagiri in central Nepal, Som Pariyar saw a snake for the first time last year. “We were shocked. Even our elders had never seen a big snake in the village in their lifetimes,” said the 38-year-old trekking guide. “Everyone can feel the change. We have mosquitoes and flies now, even at this altitude. Last June, I saw a swarm of locusts in the village for the first time.” In Lete, which sits at 3,100 metres above sea level, the ancient routines of village life are rapidly changing. Shifting weather patterns and rising temperatures across the Himalayas have seen a host of birds, animals and insect species appear at higher altitudes than ever before, some expanding into new, warmer climes, others seeking survival from the onset of climate change. Mountain villages have also found themselves exposed to new diseases for the first time in their history, as mosquitoes ascend on the warmer air. Villages in Mustang now endure regular outbreaks of malaria and dengue in a region where the diseases were previously unheard of. A 2016 report found that almost 10,000 cases of malaria had been reported since 1988 in high mountain districts where the disease was once non-existent.
