Limiting global warming now can preserve valuable freshwater resource

November 29, 2022211 Views

Study highlights wide-scale carbon mitigation strategies to maintain snowpack throughout Americas Snowcapped mountains not only look majestic – They’re vital to a delicate ecosystem that has existed for tens of thousands of years. Mountain water runoff and snowmelt flows down to streams, rivers, lakes, and oceans – and today, around a quarter of the world depends on these natural “water towers” to replenish downstream reservoirs and groundwater aquifers for urban water supplies, agricultural irrigation, and ecosystem support. But this valuable freshwater resource is in danger of disappearing. The planet is now around 1.1 degrees Celsius (1.9 degrees Fahrenheit) warmer than pre-industrial levels, and mountain snowpacks are shrinking. Last year, a study co-led by Alan Rhoades and ...

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 ...

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 ...

Marine scientists’ letter in the journal Science urges preservation of one of the last coral refuges from climate change An international group of marine scientists led by Karine Kleinhaus, of Stony Brook University’s School of Marine and Atmospheric Sciences (SoMAS), has published a letter in Science that is a call to action for policy makers, government agencies and ocean conservation groups to take major steps to preserve Egypt’s 1800 km of coral reefs– a massive section of the Red Sea’s reef system. Egypt’s reefs generate billions of dollars annually from tourism and tourism-related commerce. The reefs of the northern Red Sea are especially valuable as they constitute one of the world’s few marine refuges from climate change. Almost the entire western coastline of this ref...

More than 100 environmental activists wearing white suits stormed into an area where private jets are kept at Amsterdam's Schiphol Airport on Saturday and stopped several aircraft from departing by sitting in front of their wheels. The protest was part of a day of demonstrations in and around the airport organised by environmental groups Greenpeace and Extinction Rebellion to protest over greenhouse gas emissions and other pollution caused by the airport and aviation industry. Climate activists protest against environmental pollution from aviation at Amsterdam's Schiphol Airport, in Schiphol, Netherlands November 5, 2022.

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...

October 2022 is set to be the hottest month of October in France since records started in 1945, national weather agency Meteo-France said in a statement. With an average temperature close to or even just above 17 degrees Celsius (63 Fahrenheit) - three to four degrees above normal levels - last month was far warmer than the previous record in October 2001, when temperatures averaged 16.3C.
