Its getting tougher for glaciers to recover from climate warming

May 10, 2022330 Views

A team of scientists from Stockholm University and University of California Irvine investigated whether the Petermann Ice Shelf in northern Greenland could recover from a future breakup due to climate change. They used a sophisticated computer model to simulate the potential recovery of the ice shelf. “Even if Earth’s climate stopped warming, it would be difficult to rebuild this ice shelf once it has fallen apart”, says Henning Åkesson, who led the study at Stockholm University. “If Petermann’s ice shelf is lost, we would have to go ‘back in time’ towards a cooler climate reminiscent of the period before the industrial revolution to regrow Petermann”, Åkesson says. A crack In Petermann Ice Shelf observed by an international team of scientists during the Oden Expedition in 2019. ...

Future super cyclones would expose more people to extreme flooding

Research shows, devastating impact on people in South Asia in future years At a time, when India’s east coast is bracing for cyclone Asani, a new study has revealed that super cyclones, the most intense form of tropical storm, are likely to have a much more devastating impact on people in South Asia—including India and Bangladesh—in future years. The international research, led by the University of Bristol, looked at the 2020 Super Cyclone Amphan – the most costly cyclone to make landfall in South Asia – and projected its consequences in different scenarios of sea level rise due to global warming. Its findings, published in the Royal Meteorological Society journal Climate Resilience and Sustainability, showed if the release of greenhouse gases into the atmosphere continues at...

Global bird populations steadily declining

May 8, 20221093 Views

Study conclusion mirrors shocking losses previously shown in North America Staggering declines in bird populations are taking place around the world. So concludes a study from scientists at multiple institutions, published in the journal Annual Review of Environment and Resources. Loss and degradation of natural habitats and direct overexploitation of many species are cited as the key threats to avian biodiversity. Climate change is identified as an emerging driver of bird population declines. "We are now witnessing the first signs of a new wave of extinctions of continentally distributed bird species," says lead author Alexander Lees, senior lecturer at Manchester Metropolitan University in the United Kingdom and also a research associate at the Cornell Lab of Ornithology. "Avian d...

Emperor Penguin at serious risk of extinction due to climate change

The emperor penguin, which roams Antarctica's frozen tundra and chilly seas, is at severe risk of extinction in the next 30 to 40 years as a result of climate change, an expert from the Argentine Antarctic Institute (IAA) warned. The emperor, the world's largest penguin and one of only two penguin species endemic to Antarctica, gives birth during the Antarctic winter and requires solid sea ice from April through December to nest fledgling chicks. If the sea freezes later or melts prematurely, the emperor family cannot complete its reproductive cycle. "If the water reaches the newborn penguins, which are not ready to swim and do not have waterproof plumage, they die of the cold and drown," said biologist Marcela Libertelli, who has studied 15,000 penguins across two colonies i...

Scientists identify the most extreme heatwaves ever recorded globally

May 6, 2022537 Views

A new study has revealed the most intense heatwaves ever across the world – and remarkably some of these went almost unnoticed decades ago. The research, led by the University of Bristol, also shows heatwaves are projected to get hotter in future as climate change worsens. The western North America heatwave last summer was record-breaking with an all-time Canadian high of 49.6 °C in Lytton, British Columbia, on June 29, an increase of 4.6 °C from the previous peak. The new findings, published today in Science Advances, uncovered five other heatwaves around the world which were even more severe, but went largely underreported. Lead author, climate scientist Dr Vikki Thompson at the University of Bristol, said: “The recent heatwave in Canada and the United States shocked the...

Dangerous New Mexico wildfire menaces historic city

Hundreds of households in the historic New Mexico city of Las Vegas were told to evacuate on Monday as fierce winds and drought pushed the largest active wildfire in the United States closer to town. The blaze has scorched more than 121,000 acres (49,000 hectares), or more than half the area of New York City, tearing through centuries-old settlements and vacation homes in forested mountains 30 miles (48 kilometers) northeast of Santa Fe.

'Arcadia Earth' is an immersive environmental art exhibit in New York City that uses augmented reality to spread awareness about the impact of climate change, said the museum's founder, Valentino Vettori.

Roselle Chen/REUTERS As visitors wander throughout the rooms filled with immersive installations, such as one made of 44,000 plastic bags - the amount used in New York state every minute before the plastic bag ban - they wear an AR headset that brings the installations to life, teaching environmental facts.

Vast forest losses in 2021 imperil global climate targets, report says

The world lost an area of forest the size of the U.S. state of Wyoming last year, as wildfires in Russia set all-time records and Brazilian deforestation of the Amazon remains high, a global forest monitoring project report said on Thursday. Global Forest Watch, which is backed by the non-profit World Resources Institute (WRI) and draws on forest data collected by the University of Maryland, said in a report that roughly 253,000 square kilometers (97,683 square miles) of forest were lost in 2021.

Worsening thaw-spurred landslide curtails access to Alaska’s Denali park

April 26, 2022468 Views

For 50 years, visitors to Alaska's Denali National Park were ferried by shuttle buses along a 92-mile road to take in sweeping vistas, watch rambling bears, moose and caribou and gaze at the snowy flanks of North America's tallest peak. Not this year. This summer and next year, the park's sole road will remain closed at its halfway point, victim to a warming climate that has triggered the collapse of a mountain slope. The site, called Pretty Rocks, is at a high point on the unpaved road. Since last August, it has been considered unsafe for public travel. The landslide there used to be gradual and measured in inches per year, but it has accelerated dramatically, hastened by thawing of the underlying layers of once-perpetually frozen soil known as permafrost.

Scientists have successfully bred a threatened species of coral as part of a project that hopes to restore damaged reefs off the coast of Florida that are under threat by a relatively new disease, a coral rescue organization has said. Reefs in Florida and the Caribbean are facing growing threat of destruction by the Stony Coral Tissue Loss Disease that strips coral of its color and ultimately its life altogether. Baby rough cactus coral (Mycetophyllia ferox) is seen in a tank at the Florida Coral Rescue Center in this undated handout photo released by Seaworld.
