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

August 3, 2022905 Views

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.

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.

Cuban sea turtles can’t escape climate change, even on these far-flung beaches

On Cuba's far-flung Guanahacabibes peninsula, park guard Roberto Varela watches as a green sea turtle lumbers ashore and a ritual as old as the dinosaurs unfolds. "To see them lay their eggs and to know their nests will be protected, you get the sense you are making a difference," said Varela, who helps oversee turtle research in a national park that spans much of the peninsula. So far, efforts by Varela and fellow researchers at the park and University of Havana have been a success. Turtle nesting here, once threatened by poaching, has stabilized and increased in some cases, published studies show, even as it has fallen off elsewhere in the tropics.

Arctic temperatures are increasing four times faster than global warming

Analysis of observed temperatures finds two jumps over the past 50 years that were missed by most climate models A new analysis of observed temperatures shows the Arctic is heating up more than four times faster than the rate of global warming. The trend has stepped upward steeply twice in the last 50 years, a finding missed by all but four of 39 climate models. “Thirty years is considered the minimum to represent climate change,” said Petr Chylek, a physicist and climate researcher at Los Alamos National Laboratory and lead author of the study in Geophysical Research Letters. “We decreased the time interval to 21 years. At that smaller time scale and, contrary to previous investigations that found the Arctic amplification index increases in a smooth way, we observed two distinct st...

Top predators could ‘trap’ themselves trying to adapt to climate change, study shows

As climate change alters environments across the globe, scientists have discovered that in response, many species are shifting the timing of major life events, such as reproduction. With an earlier spring thaw, for example, some flowers bloom sooner. But scientists don’t know whether making these significant changes in life history will ultimately help a species survive or lead to bigger problems. A study published the week of June 27 in the Proceedings of the National Academy of Sciences shows for the first time that a species of large carnivore has made a major change to its life history in response to a changing climate — and may be worse off for it.

Climate change is driving 2022 extreme heat and flooding

Extreme weather events – from scorching heatwaves to unusually heavy downpours – have caused widespread upheaval across the globe this year, with thousands of people killed and millions more displaced. In the last three months, monsoon rains unleashed disastrous flooding in Bangladesh, and brutal heatwaves seared parts of South Asia and Europe. Meanwhile, prolonged drought has left millions on the brink of famine in East Africa. Much of this, scientists say, is what's expected from climate change.
