Even if the world were to cut emissions in line with the Paris Agreement, winter temperatures in the Arctic would rise 3-5°C by 2050 and 5-9°C by 2080, devastating the region and unleashing sea level rises worldwide, UN said.

If only combating global warming were as simple as collecting the CO2 in the air and burying it forever. But a European company thinks that it is just the strategy that would work against climate change
More than a third of the glaciers in the Hindu Kush Himalayan (HKH) mountain range, the "water tower" of Asia, will vanish by the end of this century even if global warming is contained at 1.50 Celsius in the best case scenario, warns a report compiled by 210 experts.
