Scientists remember the years between 2014 and 2017 as a particularly bad time for coral reefs. Elevated temperatures fueled by an El Niño climate pattern harmed about three-quarters of the…
As human activities have pushed many animal species to the margins of former habitats, some protected areas may not be located in the right places, especially as frequent extreme temperatures shrink their ranges further.
KATHMANDU — Climate change is likely to expand the habitat of leopards in the Nepal’s high mountain regions, potentially increasing conflict with humans and competition with snow leopards, a new…
BISSIL, Kenya — Heat waves are on the rise globally, and countries least culpable suffer the worst effects. While temperatures continue to rise worldwide, new research published in the journal…
Climate change-induced higher temperatures, shifting seasons, extreme drought and precipitation events, extended heat waves and fires are all impacting insects, with resonating effects on habitats, other wildlife and humanity.
KATHMANDU — Hindus in Nepal marked Tihar this past week, the festival of lights that takes place at the same time as the better-known holy day of Deepavali. But for…
As Arctic sea ice begins melting out fully in summer, the frequency of strong El Niños could increase by 35% by century's end, causing extreme weather events to increase, says recent modeling study.
Sea ice extent didn’t reach record lows this summer, but air temps over Greenland and ocean temps in some Arctic seas were extraordinarily high. Polar warming also likely continues influencing global extreme weather events, scientists say.
BARINGO COUNTY, Kenya – Last December in the town of Marigat, in Kenya's central Baringo county, Paul Chepsoi had to excuse himself from a dinner of nyama choma (roasted goat)…
The Mediterranean is a cradle — of civilization, of agriculture, of history. But the region, stretching across southern and southeastern Europe, the Middle East, and North Africa, is also a…
The world still has a fighting chance to keep temperatures below 2° Celsius over pre-industrial levels, if all countries meet their commitments to curb global warming, scientists say. In a…
The Great Barrier Reef is experiencing a sixth mass bleaching event, the marine park’s authority confirmed today after completing aerial surveys of the region. This is the fourth time the…
In 2010, an influx of cold air blew over the lower Florida Keys, chilling the subtropical waters to temperatures as low as 11° Celsius, or 52° Fahrenheit. The coral reefs…
Arctic sea ice extent continued its trending decline in winter 2022, while the Antarctic saw a record low summer minimum extent. Both regions also saw extraordinarily high temperatures for this time of year.
The fires were still several miles away, but Talía Zamboni and her colleagues wanted to work fast. Early in the morning on Feb. 23, they traveled to San Alonso Island…
Initiatives to inject billions of aerosol particles into the stratosphere to deflect solar rays and cool Earth are too risky to go forward; governments must act fast to rein in potentially disastrous planetary-scale solar geoengineering, say critics.
The crew of the M/V Arctic Sunrise, an icebreaker vessel owned by Greenpeace, were sailing through Antarctica’s Weddell Sea this month when they saw something they didn’t expect. “One of…
The ocean is now warmer than it’s ever been in recent history, according to a new study. And this isn’t the first time such a record has been set. For…
The largest and most accurate set of simulations done to date project dramatic crop productivity declines for low-latitude staples like corn in the next ten years and through 2100.
Though September sea ice extent appeared to offer a short-term recovery this fall, “that’s not the full story,” says one Arctic scientist, with low ice concentration seen in 2021, and lack of multiyear ice setting a new record.
A huge debate has raged among climate modelers for decades as to how climate change will alter clouds, making Earth cooler or warmer. New research using a machine learning model agrees with the majority view: Clouds will make for a warmer world.
The year 2021 is a La Niña year, and La Niña events typically lead to droughts in southeastern Brazil where São Paulo, the world’s fourth largest city, is located. La…
Nearly half of Brazil’s savanna biome has already been lost to agriculture. Scientists say further deforestation may bring biodiversity collapse and disastrous drought, putting Brazil’s water supply and agricultural economy at grave risk.
Researchers are seeking to pinpoint climate change “tipping points,” but defining what that means exactly, when it will come, and what makes it happen, is unimaginably difficult when faced with the chaotic complexities of a vast Earth biome.
Sea ice fell to its lowest extent on record for this time of year, while new studies find Arctic coastal ice may be receding 70-110% faster than thought, winter ice is failing to regrow fully, and last multi-year ice refuge is under assault.
New research finds that ice in both polar regions, and especially sea ice, is disappearing at a quickening rate, while in the Arctic the last stronghold of multiyear ice is under assault from warming.
Tropical trees have shorter life spans than trees in other parts of the world, living, for example, just over half as long as temperate trees. A new analysis suggests that,…
The Arctic is setting records for low sea ice extent for this time of year, with the 2020 refreeze now 500,000+ square kilometers behind a record set in 2019 — a sign the region may be entering a new climate regime.
2020 didn’t eclipse all-time record-holder 2012, but it came pretty close; also, the Arctic’s growing heat is likely intensifying Asia’s extreme weather, while waters just beneath the ice are getting increasingly warm.
By 2070, rising soil temperatures could cause germination failure in 20% of tropical plants, and reduced rates in more than 50%, with the potential to disrupt and alter tropical ecosystems.
