What worries one of the world’s leading climate scientists the most?Heatwaves — and particularly the tendency of current models to underestimate the intensity of these bursts of deadly, searing temperature.This is one of the “major mysteries” science still has to unravel, c
Meteorologists were stunned this week when three successive thunderstorms swept across the icy Arctic from Siberia to north of Alaska, unleashing lightning bolts in an unusual phenomenon that scientists say will become less rare with global warming.“Forecasters hadn’t seen anything lik
As luck would have it, the air quality sensors that University of Utah researcher Daniel Mendoza and his colleagues installed in Park City, Utah in September 2019, hoping to observe how pollution rose and fell through the ski season and the Sundance Film Festival, captured a far more impactful nat
Two model studies document the probability of climate tipping in Earth subsystems. The findings support the urgency of restricting CO2 emissions as abrupt climate changes might be less predictable and more widespread in the climate system than anticipated. The work is part of the European TiP
A team of scientists has developed a new model for simulating both iceberg calving and the tsunamis that are triggered as a result. Their method can help improve hazard assessment in coastal areas and refine the empirical calving models used to evaluate rising sea levels.
Woods Hole Oceanographic Institution (WHOI) climate modeler Dr. Alan Condron and United States Geological Survey (USGS) research geologist Dr. Jenna Hill have found evidence that massive icebergs from roughly 31,000 years ago drifted more than 5000km (> 3,000 miles) along the eastern United Sta
Polynesian seafarers likely reached Antarctica hundreds of years before the Western explorers usually credited with discovering the frozen continent, a new study has concluded.
New Zealand researchers scoured so-called "grey literature" -- including oral records, historic indigenous artworks and
The administration of President Joe Biden on Friday announced it would restore protections under the Endangered Species Act, a law credited with saving iconic animals like the gray wolf and bald eagle, which were loosened by his predecessor Donald Trump.
Conservation groups welcomed the m
A catastrophic drop in atmospheric ozone levels around the tropics is likely to have contributed to a bottleneck in the human population around 60 to 100,000 years ago, an international research team has suggested. The ozone loss, triggered by the eruption of the Toba supervolcano located in prese
India’s eastern coast is on alert for a severe cyclone brewing in the Bay of Bengal, days after a powerful storm battered the western coast, killing at least 140 people.
Cyclone Yaas is expected to make landfall on Wednesday and could pack sustained winds of up to 165 kilometres per hour, t
A cyclone, known as Jobo, made landfall near Dar es Salaam in late April. By this point it had weakened to a tropical depression and impacts were, thankfully, minimal.
Land-falling tropical cyclones are rare in Tanzania so past events are outside the memory of most
A huge iceberg, the world's largest, has broken off from an ice shelf in Antarctica and is floating through the Weddell Sea, the European Space Agency said.
Called A-76 and roughly the shape of Manhattan but more than 70 times bigger, it was picked up on satellite images and is "currently the lar
Water in the high-mountain regions has many faces. Frozen in the ground, it is like a cement foundation that keeps slopes stable. Glacial ice and snow supply the rivers and thus the foothills with water for drinking and agriculture during the melt season. Intense downpours with flash floods and la
Some 127 people were missing Tuesday after a vessel adrift off Mumbai’s coast sank during Cyclone Tauktae, the Indian navy said as two ships and helicopters were deployed to assist in the search.The vessel was carrying 273 people when it started drifting on Monday as strong winds batte
The Earth's first forest fires appear to have occurred earlier than previously thought, pointing out a link between widespread wildfires and ancient tree evolution, according to researchers at The University of Alabama.
Although small wildfires of primordial vascular plants without le
It’s official. The Amazon has ‘flipped’ and now emits more carbon pollution than it soaks.
The dense rainforest that was long believed to be absorbing human-caused pollution, released nearly 20 per cent more carbon dioxide into the atmosphere over the last decade than it absorbe
Glaciers are melting at an accelerated rate, a new large-scale study has confirmed.
They are losing 31 per cent more snow and ice per year than they did 15 years earlier, according to three-dimensional satellite measurements of all the world’s mountain glaciers.
Scientists are pinning it o
Global sea level rise associated with the possible collapse of the West Antarctic Ice Sheet has been significantly underestimated in previous studies, meaning sea level in a warming world will be greater than anticipated, according to a new study from Harvard researchers.
