he speed of the melting ice and thawing permafrost and the risk of crossing thresholds and tipping points, which have increased with the continued rise in global greenhouse emissions. There is special concern about the ticking timebomb of melting permafrost and its potential to release vast quantities of methane, which is a powerful greenhouse gas.

It noted the “almost irreversible retreat of some 200,000 glaciers, located in Europe, Africa, Oceania, Asia and the Americas.”

The years 2021 and 2022 saw a massive loss in mountain glaciers, which on average was 20% higher than the previous decade.  It is already expected that at least half of these glaciers will be lost by 2100.

Surface temperatures have increased in the Arctic by up to four times the global average in the past forty years and a huge loss of ice sheets in Greenland and Antarctica. This loss has increased four-fold in 30 years, thus contributing to average sea levels rising at a faster rate.

October Antarctic sea ice extent was the lowest on record for the time of year for the sixth consecutive month, and has been accompanied by dramatic ecological changes, including catastrophic losses in Emperor Penguin populations.

Summit participants also warned about the impact of the retreat of high mountain glaciers. The food and drinking water security of two billion people depend on high elevation glaciers, and they will suffer from disastrous effects on the flow of rivers, agriculture and electricity production.

One person in ten lives in a coastal area and will be exposed to the effects of rising sea levels, which is half due to the melting of the cryosphere, at a rate which has been increasing since the 1990s.

“We human beings do have the ability to act in equitable ways to make a difference and avoid the worst impacts of climate change,” said Jim Skea, Chair of the Intergovernmental Panel on Climate Change.

We've lost 35% of 🌍 wetlands since 1970⚠️

Wetlands are key #ForNature & for cities as they are nature's filters, regulating ecosystems by cleansing pollutants & enhancing water quality

A rare cloud-free view over Iceland! ❄️

This @CopernicusEU #Sentinel3 image of Iceland was captured on 14 August 2020.

The biggest white area shows the Vatnajökull National Park. Vatnajökull Glacier is Europe's biggest glacier, covering an area of around 8400 sq km with an average ice thickness of more than 900 m!
