European climate agency says this will likely be the hottest year on record — again

November 9, 2024181 Views

For the second year in a row, Earth will almost certainly be the hottest it’s ever been. And for the first time, the globe this year reached more than 1.5 degrees Celsius (2.7 degrees Fahrenheit) of warming compared to the pre-industrial average, the European climate agency Copernicus said Thursday. “It’s this relentless nature of the warming that I think is worrying,” said Carlo Buontempo, director of Copernicus. Buontempo said the data clearly shows the planet would not see such a long sequence of record-breaking temperatures without the constant increase of greenhouse gases in the atmosphere driving global warming. He cited other factors that contribute to exceptionally warm years like last year and this one. They include El Nino — the temporary warming of parts of the Pac...

Is climate change lighting a fuse under Iceland’s volcanoes?

Scientists are racing to find out whether the rapid retreat of glaciers could drive a surge in eruptions as magma builds under the island nation — and if so, whether the same might occur at ice-covered volcanoes around the world, putting many lives at risk. Toxic sulphurous gas, carrying the telltale reek of rotten eggs, wafted through vents in the steep walls of Iceland’s Viti crater, while carbon dioxide bubbled to the surface of the milky blue crater lake. Veils of steam wreathed the landscape of loose rock in eerie half-light. Through this forbidding terrain – “Viti” is derived from the Icelandic for “hell” – Michelle Parks, a volcanologist with the Icelandic Meteorological Office, picked her way toward the water’s edge one day last August. With a monitor strapped...

Vegetation is taking over snow in Antarctica

Lush landscape is spreading at an alarming rate in a place where temperatures are soaring A fast-warming region of Antarctica is getting greener with shocking speed. Satellite imagery of the region reveals that the area covered by plants increased by almost 14 times over 35 years — a trend that will spur rapid change of Antarctic ecosystems. “It's the beginning of dramatic transformation,” says Olly Bartlett, a remote-sensing specialist at the University of Hertfordshire in Hatfield, UK, and an author of the study, published recently in Nature Geoscience, that reports these results. From white to green Bartlett and his colleagues analysed images taken between 1986 and 2021 of the Antarctic Peninsula — a part of the continent that juts north towards the tip of South America.

Hottest oceans in 400 years endanger Great Barrier Reef, scientists say

Water temperatures in and around Australia's Great Barrier Reef have risen to their warmest in 400 years over the past decade, placing the world's largest reef under threat, according to research published on Thursday. The reef, the world's largest living ecosystem, stretches for some 1,500 miles (2,400 km) off the coast of the northern state of Queensland. A group of scientists at universities across Australia drilled cores into the coral and, much like counting the rings on a tree, analysed the samples to measure summer ocean temperatures going back to 1618.

The summer of 2023 was the hottest on record, according to data from the European Union Climate Change Service released on Wednesday. The three-month period from June through August surpassed previous records by a large margin, with an average temperature of 16.8 degrees Celsius (62.2F) - 0.66C above average. Last month was the also the hottest August on record globally, the third straight month in a row to set such a record following the hottest ever June and July, the EU said on Wednesday.

Florida’s rising temperatures raise concerns for humans as well as corals

Rising temperatures in Florida's waters due to climate change have sparked an extreme stressor for coral reefs causing bleaching, which has scientists concerned. Record global ocean heating has invaded Florida with a vengeance. Water temperatures in the mid-90s (mid-30s Celsius) are threatening delicate coral reefs, depriving swimmers of cooling dips and adding a bit more ick to the Sunshine State’s already oppressive summer weather. Forecasters are warning of temperatures that with humidity will feel like 110 degrees (43 degrees Celsius) by week’s end. If that’s not enough, Florida is about to get a dose of dust from Africa’s Saharan desert that’s likely to hurt air quality. Citizen scientist from Mote Laboratories replants corals on Florida's Keys vulnerable reefs, in Key West,...

Greece closed the ancient Acropolis during the hottest part of the day on Friday to protect tourists as southern Europe suffered in a fierce heatwave, while more than 100 million Americans also faced a prolonged spell of sweltering weather. Spain sweltered under an unrelenting heat wave Wednesday as temperatures started to build toward what is forecast to be a torrid weekend across southern Europe. The European Space Agency (ESA), whose satellites monitor land and sea temperatures, has warned that Italy, Spain, France, Germany and Poland are all facing extreme conditions.

Earth keeps breaking temperature records due to global warming On Monday, the global average temperature was the highest it’s ever been. It was even hotter on Tuesday. June was hottest June on record globally Global temperatures have smashed through records this week, underscoring the dangers of ever-increasing greenhouse gas emissions generated from burning fossil fuels. The average worldwide temperature reached 17C (63F) on Monday, just above the previous record of 16.9C in August 2016, according to data from the National Centers for Environmental Prediction. The threshold only lasted a day. On Tuesday, July 4, 2023, the average temperature hit 17.2C. This past June was also the hottest June globally on record in terms of sea and air temperatures, according to a statement by ...

Four major climate tipping points close to triggering

September 9, 2022418 Views

Even if the world somehow manages to limit future warming to the strictest international temperature goal, four Earth-changing climate “tipping points” are still likely to be triggered with a lot more looming as the planet heats more after that, a new study said. An international team of scientists looked at 16 climate tipping points — when a warming side effect is irreversible, self-perpetuating and major — and calculated rough temperature thresholds at which they are triggered. None of them are considered likely at current temperatures, though a few are possible. But with only a few more tenths of a degree of warming from now, at 1.5 degrees Celsius (2.7 degrees Fahrenheit) warming since pre-industrial times, four move into the likely range, according to a study in Thursday’s journal...

Firefighters from across Europe came to France's rescue on Friday to battle a massive wildfire, while fire also raged in Portugal and parts of England faced a severe drought, as successive heatwaves renewed the focus on climate change risks. Much of Europe has faced weeks of baking temperatures that have also depleted water levels of the Rhine River in Germany and seen the source of Britain's River Thames dry up further downstream than in previous years.
