Protected areas serve as climate change refugia

November 3, 2022709 Views

Provide thermal buffer to biodiversity, besides habitat Climate change is emerging as a top threat to biodiversity according to the latest Global Assessment Report on Biodiversity and Ecosystem Services. Plant and animal species face greater risks of thermal stress as climate change pushes temperatures beyond their thermal tolerance. A new study, published in Science Advances on Nov. 2, shows that terrestrial protected areas not only provide habitat, but also offer a thermal buffer against climate change, thus serving as climate change refugia for biodiversity. This study was led by scientists from the Institute of Atmospheric Physics of the Chinese Academy of Sciences, in collaboration with colleagues from China's Nanjing University of Information Science and Technology, the...

Climate Migration: Nomads move to towns in warming Ladakh

For decades, Konchok Dorjey grazed the world’s finest cashmere-producing goats in the arid, treeless Kharnak village in India’s Ladakh region, a high mountainous cold desert that borders China and Pakistan. But a decade ago, the 45-year-old nomad gave up his pastoral life in search of a better future for his family. He sold off his animals and migrated to an urban settlement in the outskirts of a regional town called Leh. Dorjey now lives with his wife, two daughters and a son in Kharnakling, where scores of other nomadic families from his native village have also settled in the last two decades.

As winters shorten, tiny ticks threaten state’s mighty moose

Shorter winters in Maine’s woodlands have created a huge problem for the state’s iconic moose, in the form of tiny blood-sucking ticks that thrive in warmer weather and which last year killed nearly 90% of Maine moose calves. Now the northern New England state is studying a counter-intuitive solution to the climate-driven problem: can Maine help its moose population by allowing big game hunters to kill more rather than less of them each autumn? “We’ve seen that areas with lower moose density tend to have healthier moose with fewer ticks,” said state Moose Biologist Lee Kantar, who is running the study. “The ticks can’t survive without a host.” Maine’s messy dilemma reflects how climate change is transforming biospheres the world over by expanding the northward range of parasi...

Emperor penguins now a threatened species due to climate change

Antarctica’s emperor penguin is at risk of extinction due to rising global temperatures and sea ice loss, the U.S. government said Tuesday as it finalized protections for the animal under the U.S. Endangered Species Act. The U.S. Fish and Wildlife Service said emperor penguins should be protected under the law since the birds build colonies and raise their young on the Antarctic ice threatened by climate change. The wildlife agency said a thorough review of evidence, including satellite data from 40 years showed the penguins aren’t currently in danger of extinction, but rising temperatures signal that is likely. The agency's review followed a 2011 petition by the environmental group Center for Biological Diversity to list the bird under the Endangered Species Act. FILE PHOTO: Emp...

Months after floods, Brazil’s Amazon faces a severe drought

Just months after enduring floods that destroyed crops and submerged entire communities, thousands of families in the Brazilian Amazon are now dealing with severe drought that, at least in some areas, is the worst in decades. The low level of the Amazon River, at the center of the largest drainage system in the world, has put dozens of municipalities under alert. The fast-decreasing river water level is due to lower-than-expected rainfall during August and September, according to Luna Gripp, a geosciences researcher who monitors the western Amazon’s river levels for the Brazilian Geological Survey.

Future emissions from ‘country of permafrost’ significant

Greenhouse gases emitting from Arctic must be factored into global climate targets By the end of this century, permafrost in the rapidly warming Arctic will likely emit as much carbon dioxide and methane into the atmosphere as a large industrial nation, and potentially more than the U.S. has emitted since the start of the industrial revolution. But that’s only one possible future for the vast stores of carbon locked in the formerly perennially frozen but now-thawing ground in the Arctic. Using more than a decade of synthesis science and region-based models, a new study led by Northern Arizona University and the international Permafrost Carbon Network and published in Annual Review of Environment and Resources forecasts cumulative emissions from this “country of permafrost” through 2...

Sea level rise now menaces even a Viking bastion of uplifted land

About 1,000 years ago, a Viking woman named Ingrid built a wharf to load ships at a bay on the Swedish coast and commemorated the site with a looping runic inscription on a grey boulder. Today Ingrid’s harbour, surrounded by birch and pine trees, is high and dry, on land 5 metres (16 feet) above sea level and 20 kms (12 miles) inland from coastal Stockholm, on the Baltic Sea. Land across much of the Nordic region has been rebounding since the end of the Ice Age about 12,000 years ago, as a heavy smothering of ice up to 3 km (1.9 miles) thick melted away. That rise should make the region an unlikely candidate to suffer problems from a global rise in ocean levels as seas warm and glaciers melt - a threat for low-lying nations and coastal cities around the world, from Shanghai to Mi...

Half of the world’s coral reefs may face unsuitable conditions by 2035

Researchers assess the dire consequences of climate change under a business-as-usual scenario There’s more bad news for planet earth if climate change continues unabated. New research published on October 11th in the open access journal PLOS Biology by researchers at the University of Hawaiʻi at Mānoa, United States reveals that, under a worst-case scenario, half of coral reef ecosystems worldwide will permanently face unsuitable conditions in just a dozen years.

As Himalayan glaciers melt, a water crisis looms in South Asia

Warmer air is thinning most of the vast mountain range’s glaciers, known as the Third Pole because they contain so much ice. The melting could have far-reaching consequences for flood risk and for water security for a billion people who rely on meltwater for their survival. Spring came early this year in the high mountains of Gilgit-Baltistan, a remote border region of Pakistan. Record temperatures in March and April hastened melting of the Shisper Glacier, creating a lake that swelled and, on May 7, burst through an ice dam. A torrent of water and debris flooded the valley below, damaging fields and houses, wrecking two power plants, and washing away parts of the main highway and a bridge connecting Pakistan and China. Pakistan’s climate change minister, Sherry Rehman, tweeted vide...

Missing snow puts famed New Zealand ski areas on precipice

New Zealand’s Tūroa ski area is usually a white wonderland at this time of year, its deep snowpack supporting its famed spring skiing. This season, it’s largely a barren moonscape, with tiny patches of snow poking out between vast fields of jagged volcanic boulders. The ski area was forced to close for the season this week, three weeks earlier than planned. Rain repeatedly washed away the snow, and the ski area’s 50 snowmaking machines proved no match against balmy temperatures. Climate change appears to be a significant factor, after New Zealand experienced its warmest winter on record — for the third year in a row.
