Worst melt year on record for Swiss glaciers

September 28, 2022502 Views

Swiss glaciers have recorded their worst melt rate since records began more than a century ago, losing 6% of their remaining volume this year or nearly double the previous record of 2003, monitoring body GLAMOS said on Wednesday. The melt was so extreme this year that bare rock that had remained buried for millenia re-emerged at one site while bodies and even a plane lost elsewhere in the Alps decades ago were recovered. Other small glaciers all but vanished.

Mangroves have been capturing carbon for 5,000 years

Unusual forests on stilts mitigate climate change, Mexican research shows Researchers have identified a new reason to protect mangrove forests: they’ve been quietly keeping carbon out of Earth’s atmosphere for the past 5,000 years. Mangroves thrive in conditions most plants cannot tolerate, like salty coastal waters. Some species have air-conducting, vertical roots that act like snorkels when tides are high, giving the appearance of trees floating on stilts. A UC Riverside and UC San Diego-led research team set out to understand how marine mangroves off the coast of La Paz, Mexico, absorb and release elements like nitrogen and carbon, processes called biogeochemical cycling.

100 years after compact, Colorado River nearing crisis point

The intensifying crisis facing the Colorado River amounts to what is fundamentally a math problem. The 40 million people who depend on the river to fill up a glass of water at the dinner table or wash their clothes or grow food across millions of acres use significantly more each year than actually flows through the banks of the Colorado. In fact, first sliced up 100 years ago in a document known as the Colorado River Compact, the calculation of who gets what amount of that water may never have been balanced.

Rocky path revealed between Swiss glaciers in extreme melt season

A rocky Alpine path between two glaciers in Switzerland is emerging for what the local ski resort says is the first time in at least 2,000 years after the hottest European summer on record. Hikers walk past the newly uncovered Zanfeluron path, as a split of the Sex-Rouge and the Zanfleuron Glacier revealed the path for the first time in 2000 years due to this summer heatwave, at Glacier 3000 in Les Diablerets, Switzerland, September 11, 2022. REUTERS/Denis Balibouse The ski resort of Glacier 3000 in western Switzerland said this year's ice melt was around three times the 10-year average, meaning bare rock can now be seen between the Scex Rouge and the Zanfleuron glaciers at an altitude of 2,800 metres and the pass will be completely exposed by the end of this month. "About 10 yea...

Four major climate tipping points close to triggering

September 9, 2022431 Views

Even if the world somehow manages to limit future warming to the strictest international temperature goal, four Earth-changing climate “tipping points” are still likely to be triggered with a lot more looming as the planet heats more after that, a new study said. An international team of scientists looked at 16 climate tipping points — when a warming side effect is irreversible, self-perpetuating and major — and calculated rough temperature thresholds at which they are triggered. None of them are considered likely at current temperatures, though a few are possible. But with only a few more tenths of a degree of warming from now, at 1.5 degrees Celsius (2.7 degrees Fahrenheit) warming since pre-industrial times, four move into the likely range, according to a study in Thursday’s journal...

World Cup fans to put Qatar’s green goals under pressure

The Middle East's first ever soccer World Cup promises boom time for Dubai hotels this November, with thousands of fans expected to descend on the Gulf city due to limited accommodation in neighbouring host nation Qatar. But the environmental costs of transporting those visitors nearly 400 km (249 miles) for match days, overwhelmingly by plane, raises further doubts over Qatar's pledge last year to host the first ever carbon-neutral World Cup. FILE PHOTO: Flag raising ceremony for the last three teams to qualify for the 2022 World Cup - Doha, Qatar - June 16, 2022 General view during the ceremony REUTERS/Mohammed Dabbous While more than a million soccer fans are expected to attend the tournament, Qatar had just 30,000 hotel rooms as of March. More are due to be added before the t...

East Mediterranean especially at risk as world heats up

September 6, 2022231 Views

The eastern Mediterranean and Middle East are warming almost twice as fast as the global average, with temperatures projected to rise up to 5 degrees Celsius (9 degrees Fahrenheit) by the end of the century if no action is taken to reverse the trend, a new report says. The region will experience “unprecedented” heat waves, more severe and longer-lasting droughts and dust storms and rainfall shortages that will “compromise water and food security” for the region’s 400 million people, according to a summary of the report released Tuesday. The eastern Mediterranean and the Middle East are more susceptible to warming trends because of their unique natural characteristics, like large desert expanses and lower water levels, the study said.

Renowned date palms in Africa’s hottest oasis are threatened

In an oasis notorious as the hottest place in Africa, Tunisian farmers say they are fighting a losing battle with drought and disease that is driving many to abandon plantations where they grow some of the world's finest dates. The date palm orchards at Kebili oasis used to form green, fertile islands in an arid landscape. But now many of the trees are dying, and dry, bare and fruitless trunks stretch up into a clear blue sky.

Zimbabwe moves 2,500 wild animals due to climate change

A helicopter herds thousands of impalas into an enclosure. A crane hoists sedated upside-down elephants into trailers. Hordes of rangers drive other animals into metal cages and a convoy of trucks starts a journey of about 700 kilometers (435 miles) to take the animals to their new home. Zimbabwe has begun moving more than 2,500 wild animals from a southern reserve to one in the country’s north to rescue them from drought, as the ravages of climate change replace poaching as the biggest threat to wildlife. About 400 elephants, 2,000 impalas, 70 giraffes, 50 buffaloes, 50 wildebeest, 50 zebras, 50 elands, 10 lions and a pack of 10 wild dogs are among the animals being moved from Zimbabwe’s Save Valley Conservancy to three conservancies in the north — Sapi, Matusadonha and Chizari...

Weather whiplash: Summer lurches from drought to flood

Parts of northern Texas, mired in a drought labeled as extreme and exceptional, are flooding under torrential rain. In a drought. Sound familiar? It should. The Dallas region is just the latest drought-suffering-but-flooded locale during a summer of extreme weather whiplash, likely goosed by human-caused climate change, scientists say. Parts of the world are lurching from drought to deluge. The St. Louis area and 88% of Kentucky early in July were considered abnormally dry and then the skies opened up, the rain poured in biblical proportions, inch after inch, and deadly flooding devastated communities. The same thing happened in Yellowstone in June. Earlier this month, Death Valley, in a severe drought, got a near record amount of rainfall in one day, causing floods, and is still in...
