As air pollution decreases in the western Northern Hemisphere, several new climate simulations suggest tropical cyclones in the Atlantic may increase. The forecast is troubling, though not necessarily a surprise. When tiny aerosols like dust, soot, and sulfates are airborne, they create smog that can dim sunlight and cool Earth’s atmosphere and surface. Broadly speaking,

All heatwaves today bear the unmistakable and measurable fingerprint of global warming, top experts on quantifying the impact of climate change on extreme weather said Wednesday. Burning fossil fuels and destroying forests have released enough greenhouse gases into the atmosphere to also boost the frequency and intensity of many floods, droughts, wildfires, and tropical storms,

In a warmer world, rising sea levels could render many coastlines, beaches, and reef islands uninhabitable, or destroy them altogether. The 1.09℃ Earth has warmed since pre-industrial times has already heightened seas by 20 centimeters. But curiously, research shows some coastlines and even low-lying coral reef islands are actually growing rather than eroding in the

Tiny parasites could be hitchhiking on microplastics floating in the ocean and then hopping to ocean life. Under laboratory conditions, researchers have shown three common germs – Toxoplasma gondii, Giardia, and Cryptosporidium – are more than capable of adhering to synthetic microbeads and microfibers. This may not be happening in the real world, but the

Australia’s spectacular Great Barrier Reef is suffering “mass bleaching” as corals lose their color under the stress of warmer seas, authorities said Friday, in a blow widely blamed on climate change. The world’s largest coral reef system, stretching for more than 2,300 kilometers (1,400 miles) along the northeast coast of Australia, is showing the harmful

Record-breaking heatwaves hit both Antarctica and the Arctic simultaneously this week, with temperatures reaching 47°C and 30°C higher than normal. Heatwaves are bizarre at any time in Antarctica, but particularly now at the equinox as Antarctica is about to descend into winter darkness. Likewise, up north, the Arctic is just emerging from winter. Are these

Eastern Antarctica has recorded exceptionally high temperatures this week, more than 30 degrees Celsius above normal, say experts. The Concordia research base at Dome C of the Antarctic, which is at an altitude of 3,000 meters (9,800 feet), on Friday registered a record -11.5 degrees Celsius (11.3 Fahrenheit), Etienne Kapikian, a meteorologist from France-Meteo tweeted.

The Great Barrier Reef has again been hit with “widespread” bleaching, authorities said Friday, as higher-than-average ocean temperatures off Australia’s northeast threaten the already struggling World Heritage site. Surveillance flights over the reef revealed damage due to heat stress ranging from minor to severe bleaching across the 2,300-kilometer (1,243-mile) network of corals, the Great Barrier

Hammered by climate change and relentless deforestation, the Amazon rainforest is losing its capacity to recover and could irretrievably transition into savannah, with dire consequences for the region and the world, according to a study published Monday. Researchers warned that the results mean the Amazon could be approaching a so-called “tipping point” faster than previously

Rising global temperatures bring dire threats, such as floods, heat-related injuries, water scarcity, and hunger, making up to 3.6 billion people – nearly half of the world’s population – highly vulnerable to climate change. That’s according to a major report, released Monday, from the Intergovernmental Panel on Climate Change – a UN body that recruits

Nearly 200 nations approved a major UN climate change report detailing the accelerating impacts of global warming on Sunday, at the end of a sometimes fraught two-week meeting overshadowed by Russia’s invasion of Ukraine. The Intergovernmental Panel on Climate Change (IPCC) confirmed that debates had concluded over the report’s crucial “Summary for Policymakers”, a 40-page

Every summer, as the sea ice surrounding Antarctica retreats, tens of thousands of tourists and scientists flock to the landmass by boat and plane. The remote continent is becoming increasingly accessible – during the 2019-20 season, the number of sightseeing visitors reached 74,000, with the vast majority traveling by ship. Scientific activities on the continent
