New ice core analysis shows sharp Greenland warming spike

January 20, 2023958 Views

A sharp spike in Greenland temperatures since 1995 showed the giant northern island 2.7 degrees (1.5 degrees Celsius) hotter than its 20th-century average, the warmest in more than 1,000 years, according to new ice core data. Until now Greenland ice cores -- a glimpse into long-running temperatures before thermometers -- hadn’t shown much of a clear signal of global warming on the remotest north central part of the island, at least compared to the rest of the world. But the ice cores also hadn’t been updated since 1995. Newly analyzed cores, drilled in 2011, show a dramatic rise in temperature in the previous 15 years, according to a study in Wednesday’s journal Nature. “We keep on (seeing) rising temperatures between 1990s and 2011,” said study lead author Maria Hoerhold, a glaciol...

Climate change likely to uproot more Amazon trees

New study connecting extreme thunderstorms and tree deaths suggests the tropics will see more major blowdown events in a warming world Tropical forests are crucial for sucking up carbon dioxide from the atmosphere. But they’re also subject to intense storms that can cause “windthrow” – the uprooting or breaking of trees. These downed trees decompose, potentially turning a forest from a carbon sink into a carbon source. Members of NGEE-Tropics visit what they named “Blowdown Gardens,” an area that experienced windthrow near one of their field sites in the Amazon. Photo Credit: Jeff Chambers/Berkeley Lab A new study finds that more extreme thunderstorms from climate change will likely cause a greater number of large windthrow events in the Amazon rainforest. This is one of the fe...

Last year tied as world’s fifth-warmest on record, scientists say

Last year was the world's joint fifth-warmest on record and the last nine years were the nine warmest since pre-industrial times, putting the 2015 Paris Agreement's goal to limit global warming to 1.5C in serious jeopardy, U.S. scientists have said. Last year tied with 2015 as the fifth-warmest year since record-keeping began in 1880, NASA said. That was despite the presence of the La Nina weather pattern in the Pacific Ocean, which generally lowers global temperatures slightly. The world's average global temperature is now 1.1C to 1.2C higher than in pre-industrial times.

Record-high winter temperatures swept across parts of Europe over the new year, bringing calls from activists for faster action against climate change while offering short-term respite to governments struggling with high gas prices. Hundreds of sites have seen temperature records smashed in the past days, from Switzerland to Poland to Hungary, which registered its warmest Christmas Eve in Budapest and saw temperatures climb to 18.9 degrees Celsius (66.02°F) on Jan. 1. In France, where the night of Dec. 30-31 was the warmest since records began, temperatures climbed to nearly 25C in the southwest on New Year's Day while normally bustling European ski resorts were deserted due to a lack of snow.

Skiing over Christmas holidays no longer guaranteed – even with snow guns

For many people, holidays in the snow are as much a part of the end of the year as Christmas trees and fireworks. As global warming progresses, however, white slopes are becoming increasingly rare. Researchers at the University of Basel have calculated how well one of Switzerland’s largest ski resorts will remain snow reliable with technical snowmaking by the year 2100, and how much water this snow will consume. The future for ski sports in Switzerland looks anything but rosy – or rather white. Current climate models predict that there will be more precipitation in winter in the coming decades, but that it will fall as rain instead of snow. Despite this, one investor recently spent several million Swiss francs on expanding the Andermatt-Sedrun-Disentis ski resort. A short-sighted decis...

Nomad Tsering Angchuk vows to stay put in his remote village in India’s Ladakh region. His two sons and most of his fellow villagers have migrated to a nearby urban settlement but Angchuk is determined to herd his flock of fine cashmere-producing goats in the treeless Kharnak village, a hauntingly beautiful but unforgiving, cold mountainous desert.

Limiting global warming now can preserve valuable freshwater resource

Study highlights wide-scale carbon mitigation strategies to maintain snowpack throughout Americas Snowcapped mountains not only look majestic – They’re vital to a delicate ecosystem that has existed for tens of thousands of years. Mountain water runoff and snowmelt flows down to streams, rivers, lakes, and oceans – and today, around a quarter of the world depends on these natural “water towers” to replenish downstream reservoirs and groundwater aquifers for urban water supplies, agricultural irrigation, and ecosystem support. But this valuable freshwater resource is in danger of disappearing. The planet is now around 1.1 degrees Celsius (1.9 degrees Fahrenheit) warmer than pre-industrial levels, and mountain snowpacks are shrinking. Last year, a study co-led by Alan Rhoades and ...

Major glaciers, including Dolomites and Yosemite, to disappear by 2050 – U.N. report

Some of the world's most famous glaciers, including in the Dolomites in Italy, the Yosemite and Yellowstone parks in the United States and Mount Kilimanjaro in Tanzania are set to disappear by 2050 due to global warming, whatever the temperature rise scenario, according to a UNESCO report.

REUTERS/Tracy Barbutes The United Nations cultural agency UNESCO monitors some 18,600 glaciers across 50 of its World Heritage sites and said that glaciers in one third of World Heritage sites will disappear by 2050 regardless of the applied climate scenario. While the rest can be saved by keeping global temperature rise below 1.5 degree Celsius (2.7 Fahrenheit) relative to...

For decades, Konchok Dorjey grazed the world’s finest cashmere-producing goats in the arid, treeless Kharnak village in India’s Ladakh region, a high mountainous cold desert that borders China and Pakistan. But a decade ago, the 45-year-old nomad gave up his pastoral life in search of a better future for his family. He sold off his animals and migrated to an urban settlement in the outskirts of a regional town called Leh. Dorjey now lives with his wife, two daughters and a son in Kharnakling, where scores of other nomadic families from his native village have also settled in the last two decades.

October 2022 is set to be the hottest month of October in France since records started in 1945, national weather agency Meteo-France said in a statement. With an average temperature close to or even just above 17 degrees Celsius (63 Fahrenheit) - three to four degrees above normal levels - last month was far warmer than the previous record in October 2001, when temperatures averaged 16.3C.
