Emperor Penguin at serious risk of extinction due to climate change

May 6, 2022476 Views

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

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...

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. "The intention is to inspire people to c...

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, 2022479 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.

Breeding threatened coral species to restore reefs

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.

UCI researchers reconsider carbon storage with improved climate models, satellite data In a paper published in Nature Communications, a team led by scientists from the University of California, Irvine, using climate models and satellite data, reveal for the first time how protecting tropical forests can yield climate benefits that enhance carbon storage in nearby areas. Many climate scientists use computer simulations to mimic the planet’s climate as it exists today and how it may exist in the future as humanity keeps emitting greenhouse gases. Such models rely on accurate measurements all the moving parts of the climate system, from how much sunlight hits and warms the climate, to the response of forest biomass to changes in temperature, rainfall and atmospheric carbon dioxide leve...

‘Now or never’: Only severe emissions cuts will avoid climate extremes

UN IPCC releases last of its three part series report on Climate Change Drastic cuts to fossil fuel use. Growing forests and eating less meat. These are just some of the actions needed in this decade to contain global warming to 1.5 degrees Celsius above preindustrial temperatures, a major report by the U.N. climate science agency said Monday. Despite climate change warnings issued by the Intergovernmental Panel on Climate Change (IPCC) since 1990, global emissions have continued to rise in the last decade, reaching their highest point in history. The result: global emissions are on track to blow past the 1.5 degrees C warming limit envisioned in the 2015 Paris Agreement and reach some 3.2 degrees C by century's end.

Warmer summers and meltwater lakes are damaging the fringes A first-of-its-kind study looking at surface meltwater lakes around the East Antarctic Ice Sheet across a seven-year period has found that the area and volume of these lakes is highly variable year-to-year, and offers new insights into the potential impact of recent climatic change on the ‘Frozen Continent’. The research, led by Durham University (UK), used over 2000 satellite images from around the edge of the East Antarctic Ice Sheet to determine the size and volume of lakes on the ice surface, also known as supraglacial lakes, across seven consecutive years between 2014 and 2020.
