Few mangrove species likely to reduce and shift landward

November 15, 2022428 Views

Decline in habitat to impact mangroves in east coast and west coast of India Certain mangrove species in Chilika and Sundarbans along the east coast and Dwarka and Porbandar along the west coast of India is likely to reduce and shift landward by 2070 due to decline in suitable habitats in response to precipitation and sea level changes, said a study based on a prediction model. The study can help identify highly suitable areas for conservation and management and develop conservation strategies for the future. Mangroves support numerous ecosystem services and help reduce coastal ecological risks, yet they are one of the severely endangered ecosystems declining rapidly due to climate change, sea level fluctuations, and human activities. A limited understanding of mangrove spatial ...

Climate reshapes life for tenacious gannets on Quebec isle

On Quebec’s Bonaventure Island, the ghosts of human habitation from years past and the birds that breed there now in extraordinary numbers tell the same story: of lives lived hard in a place of fairy-tale beauty. You see this from the tender ages on the family gravestones of islanders who scratched out a living from the late 1700s to when Bonaventure went entirely to the birds a half century ago. A northern gannet flies above the colony on Bonaventure Island in the Gulf of St. Lawrence off the coast of Quebec, Canada's Gaspe Peninsula, Tuesday, Sept. 13, 2022. (AP Photo/Carolyn Kaster) You see it from the tenacious colony of 100,000-plus northern gannets as they plunge into the sea for prey, soar back to their nests and fight at the least provocation, sometimes to the death, for ...

As climate shocks loom, a race to document Namibia’s rock art

Among the rambling herd painted onto the rocks of Namibia's Erongo mountains, some creatures are easy to spot - the long necks of giraffes, the spikes of antelopes' horns. Other animals have faded beyond recognition. Local guide Johannes Ikun Nani had only seen his ancestors' rock art in books, until a job took him to the country's central region, where the ancient rock paintings and engravings have become a growing tourist attraction over the years. Nani counts himself lucky to have witnessed his heritage firsthand - especially because archaeologists say climate change may be accelerating its disappearance. Johannes Ikun Nani stands in front of a boulder displaying ancient San rock at the Omandumba farm in the central region of Namibia, September 30, 2022. Thomson Reuters Founda...

Some of the world's most famous glaciers, including in the Dolomites in Italy, the Yosemite and Yellowstone parks in the United States and Mount Kilimanjaro in Tanzania are set to disappear by 2050 due to global warming, whatever the temperature rise scenario, according to a UNESCO report. FILE PHOTO: Visitors near Glacier Point wait for the sun to rise in Yosemite National Park, California, U.S. July 2, 2021. REUTERS/Tracy Barbutes The United Nations cultural agency UNESCO monitors some 18,600 glaciers across 50 of its World Heritage sites and said that glaciers in one third of World Heritage sites will disappear by 2050 regardless of the applied climate scenario. While the rest can be saved by keeping global temperature rise below 1.5 degree Celsius (2.7 Fahrenheit) relative to...

Protected areas serve as climate change refugia

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. Nomadic women milk their hardy Himalayan goats that produce cashmere in the remote Kharnak village in the cold desert region of Ladakh, India, Saturday, Sept. 17, 2022. (AP Photo/Mukhtar Kh...

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...
