African wildlife parks face climate, infrastructure threats

August 14, 20221108 Views

Africa’s national parks, home to thousands of wildlife species such as lions, elephants and buffaloes, are increasingly threatened by below-average rainfall and new infrastructure projects. A prolonged drought in much of the continent’s east, exacerbated by climate change, and large-scale developments, including oil drilling and livestock grazing, are hampering conservation efforts in protected areas, several environmental experts say.

Rapid warming in the Gulf of Maine reverses 900 years of cooling

Rapid 20th century warming in the Gulf of Maine has reversed long-term cooling that occurred there during the previous 900 years, according to new research that combines an examination of shells from long-lived ocean quahogs and climate model simulations. The warming is “likely due to increased atmospheric greenhouse gas concentrations and changes in western North Atlantic circulation,” according to the paper, “Rapid 20th century warming reverses 900-year cooling in the Gulf of Maine,” published in Communications Earth & Environment, an open access journal from Nature Portfolio.

A lose-lose game: animals are under threat as the climate gets warmer and more variable

How has climate change affected your life? Maybe torrential rains have flooded part of your town, or your city has had to contend with longer heat waves every year. Maybe you kept your attention on the news for days at a time to find out if a wildfire would change its direction and come toward you, or if a hurricane would be strong enough that you should evacuate. Climate change will continue to affect the world around us in complex and tragic ways. Increasing temperatures are causing rising ocean levels, shifting weather patterns, and threatening the survival of animals and plants. But along with increasing temperatures, the climate is also becoming more variable, and more extreme. The brown anole (Anolis sagrei) is one of the species studied by the Logan Lab and could provide valu...

13 of the 19 glaciers in Alaska show substantial retreat

New study calculates loss of glacier edges in Kenai Fjords National Park As glaciers worldwide retreat due to climate change, managers of national parks need to know what’s on the horizon to prepare for the future. A new study from the University of Washington and the National Park Service measures 38 years of change for glaciers in Kenai Fjords National Park, a stunning jewel about two hours south of Anchorage. The study, published Aug. 5 in The Journal of Glaciology, finds that 13 of the 19 glaciers show substantial retreat, four are relatively stable, and two have advanced. It also finds trends in which glacier types are disappearing fastest. The nearly 670,000-acre park hosts various glaciers: some terminate in the ocean, others in lakes or on land. Bear Glacier, shown here i...

Fiji, moving villages inundated by rising seas, wants big emitters to pay

Boats moor next to living rooms on Fiji's Serua Island, where water breaches the seawall at high tide, flooding into the village. Planks of wood stretch between some homes, forming a makeshift walkway as saltwater inundates gardens. Village elders always believed they would die here on prized land where their chiefs are buried. But as the community runs out of ways to adapt to the rising Pacific Ocean, the 80 villagers face the painful decision whether to move. Local resident Rapuma Tuqio, 67, looks out at seawater flooding around his home at high tide in Veivatuloa Village, Fiji, July 16, 2022. He has lived in the village for around 20 years, including 12 or 13 years in that seaside home. REUTERS/Loren Elliott Semisi Madanawa, raising three children who wade through playgroun...

High temperatures unleash marine heatwave in Mediterranean Sea

High temperatures across Europe this month have unleashed a prolonged marine heatwave in the Mediterranean Sea that could ravage ecosystems and kill off several species in the coming weeks, scientists have warned. The extreme heat in recent weeks has already sparked wildfires and led to thousands of heat-related deaths in Europe, but that warmth hasn't been limited to the land. The warmer air along with shifting ocean currents and a stable sea surface have warmed coastal Mediterranean waters several degrees Celsius beyond the average temperature of 24°C to 26°C for this time of year.

Climate change and vanishing islands threaten brown pelicans

Sliding off the side of her small boat, seabird biologist Bonnie Slaton wades through waist-high water, brown pelicans soaring overhead, until she reaches the shores of Raccoon Island. During seabird breeding season, the place is a raucous symphony of noise and motion — and one of the few remaining refuges for the iconic pelicans. The crescent-shaped island is the final sliver of land separating Louisiana from the Gulf of Mexico — a natural speed bump against storms that roll in from the sea. An hour’s boat ride from the mainland, the barrier island’s remoteness allows birds to nest on mangroves and sandy beaches a safe distance from most predators. Raccoon Island, a Gulf of Mexico barrier island that is a nesting ground for brown pelicans, terns, seagulls and other birds, is see...

Glaciers vanishing at record rate in Alps following heatwaves

From the way 45-year-old Swiss glaciologist Andreas Linsbauer bounds over icy crevasses, you would never guess he was carrying 10 kg of steel equipment needed to chart the decline of Switzerland's glaciers. Normally, he heads down this path on the massive Morteratsch Glacier in late September, the end of the summer melt season in the Alps. But exceptionally high ice loss this year has brought him to this 15-square-kilometer (5.8-square-mile) amphitheatre of ice two months early for emergency maintenance work. The measuring poles he uses to track changes in the depth of the pack are at risk of dislodging entirely as the ice melts away and he needs to drill new holes. Glaciologist Andreas Linsbauer and assistant Andrea Millhaeusler stand on a border moraine of the Pers Glacier near...

Mideast nations wake up to damage from climate change

Temperatures in the Middle East have risen far faster than the world’s average in the past three decades. Precipitation has been decreasing, and experts predict droughts will come with greater frequency and severity. The Middle East is one of the most vulnerable regions in the world to the impact of climate change — and already the effects are being seen. In Iraq, intensified sandstorms have repeatedly smothered cities this year, shutting down commerce and sending thousands to hospitals. Rising soil salinity in Egypt’s Nile Delta is eating away at crucial farmland. In Afghanistan, drought has helped fuel the migration of young people from their villages, searching for jobs. In recent weeks, temperatures in some parts of the region have topped 50 degrees Celsius (122 Fahrenheit). ...

Polar bears scavenge on garbage to cope with climate change

Hungry polar bears are turning to garbage dumps to fill their stomachs as their icy habitat disappears. On Wednesday, a team of Canadian and U.S. scientists warned that trash poses an emerging threat to already-vulnerable polar bear populations as the animals become more reliant on landfills near northern communities. This is leading to deadly conflicts with people, the report published in the journal Oryx said. Polar bears scavenge for food at a dump in Churchill, Canada, in this handout image dated circa 2003. In 2005, the community permanently closed its dump and now stores garbage in a secure facility. Dan Guravich/Polar Bears International/Handout via REUTERS "Bears and garbage are a bad association," said co-author Andrew Derocher, a biologist at the University of Alberta. ...
