Bangladesh has been swept up in the massive heat wave scorching large parts of Asia, with temperatures among the highest in six decades. The country’s capital, Dhaka, saw the temperature…
New research finds that a record Arctic sea ice melt season in 2007 initiated a “regime shift” to thinner, more transient ice that may be “irreversible”; another study shows that atmospheric rivers from the south are warming the Arctic in winter.
KATHMANDU — The South Col in the Sagarmatha (Mount Everest) region faces blasts of unrelenting winds that sweep away almost everything in their path, including snow. Located nearly 8,000 meters (26,000…
Analysis of 40 years of climate temperature data shows a connection between Amazon tree loss and Tibetan snow decrease via a 20,000-kilometer oceanic and atmospheric pathway. West Antarctica is also impacted.
Warmer temperatures could significantly diminish the ability of tropical forests to siphon carbon from the atmosphere by intensifying dry seasons, according to a recent study. The tropics pack away an…
Collecting core samples from the Greenland ice sheet is no easy task. During a recent expedition, scientists and drilling experts boarded a ski-equipped aircraft and flew to a site at…
Brazilian scientist Antonio Donato Nobre has long been a student of the Amazon Rainforest. An agronomist with a master's degree in tropical biology and a Ph.D. in Earth science, Nobre…
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.
