Earth risks losing 40% of glacial mass if it doesn’t give up fossil fuels, projection warns | Climate News

If humanity continues to invest in fossil fuels, more than 40 percent of Earth’s ice mass could disappear, a brand new projection warns.

The bleak scenario would mean that more than two-thirds of the total number of glaciers would disappear by the end of this century, leading to continued sea level rise worldwide.

Lead researcher David Rones, an assistant professor of civil and environmental engineering at the Pittsburgh College of Engineering, led an international effort to develop the new projection.

Even in this best-case scenario, Prof Rones’ team found that around 50% of glaciers would disappear, accounting for more than 25% of the total ice mass by 2100.

A previous study warned that Earth Already set for a 1.5C temperature rise..

Although most of the glaciers lost by Professor Rounce’s estimate are small by global standards, measuring less than one square kilometre, many of these glaciers will increase in size as they disappear.

The devastating glacier damage is already being felt around the world.

last year, Switzerland’s glaciers have shrunk by half in less than a century. – and the country’s oldest glacier had to be covered with a special white blanket to prevent it from melting.

The meltdown was so intense that a Sky News team was able to observe the wreckage of the 1968 plane. which re-emerged without warning in the Swiss Alps when the snow covering it began to melt.

Melting glaciers also contributed to last summer’s devastating floods in Pakistan.which is home to more glaciers than anywhere outside the Arctic and Antarctic.

Located in the northern Himalayas, Pakistan has around 7,000 glaciers, and rising temperatures – which are expected to reach around 50C (122F) in Nawabshah city in 2022 – are causing them to melt and form glacial lakes. .

Scientists have also issued warnings about the melting of Antarctica’s so-called “doomsday glaciers”, whose complete collapse could raise sea levels by up to 60cm.

The impact will be so far-reaching. It would also have “serious consequences” for Britain..

But Prof Rones warned that even a complete halt to global emissions would not appear at the rate that glaciers are disappearing for decades – possibly 100 years.

He describes glaciers as “very slow-moving rivers”, which take time to feel their effects.

Major glaciers will be gone by 2050.
