Breaking Waves: Ocean News

As the UK climate changes, many species are marching towards cooler climes – but trees are being outpaced. Some ecologists say assisted movement is the answer At the top of an ancient oak at Knepp estate in West Sussex, a white stork has made a scruffy nest. The birds made headlines in 2020 when, after an absence of centuries in the UK, the first chick hatched. Alongside bison, beavers and white-tailed eagles, the storks are one of many species reintroduced to Britain in recent decades in an effort to restore animals to ecosystems where they had been wiped out. The oak tree, by contrast, has been here continuously for 12,000 years. But ecologist Charlie Gardner is worried one of them may not have a future here – and it’s the oak. By 2050, London’s weather could resemble that of Barcelona, with long stretches of summer drought. These ancient trees were not designed to thrive in such conditions. “More and more individual trees will die and reproductive success will fall,” says Gardner. Around the world, millions of creatures facing unprecedented temperatures and habitat loss are on the move. The climate crisis is causing a vast array of species – from algae to butterflies, woodlice to birds – to shift northwards. Species are travelling north at a median rate of 17km a decade, according to 2011 research. That average equates to 20cm an hour – two to three times faster than previous estimates.

While tourists flock to the Italian island in greater numbers, a water crisis is intensifying for its rural population For the first time in four generations of his family’s farming history, Vito Amantia’s threshers have lain silent this year. The 650,000kg of wheat that his farm would usually produce in a year has been lost, parched and withered under the scorching sun and relentless drought. “A seasoned farmer doesn’t need to check the weather forecast to understand what the weather will be like,” says Amantia, 68, who farms on the Catania plain in eastern Sicily. “Already last January, I knew it would be a disastrous year. The wheat seedlings that normally reached 80cm stopped at 5cm. Then they dried up.” Continue reading...

The death of a young woman falling from the famous – and ever more popular – Half Dome in Yosemite ignites debate In 1974, Scott Crollard, a teen on a church youth group trip, casually climbed cables to help reach the lofty summit of Half Dome, whose name describes a unique rock formation in California from which you can see the Yosemite Valley some 5,000ft below. “I remember sitting on the edge of the lip of Half Dome with my buddy and just gazing over the edge. And when he got off, he kind of nudged me, and I darn near fell off the thing just because we were so nonchalant about it,” said Collard, now a 65-year-old retired emergency room physician in St Louis who again ascended Half Dome in 2017 with more appreciation for its magnitude.

Travel companies are reporting a surge of interest in people wanting to get away from light pollution and into nature For the campers at the Dark Skies site near the Cambrian mountains in Wales, the blackness of the pitches is an important draw. “When people come, they are blown away by the night sky,” said Tanya Jordan, who owns the site and holiday cottages nearby. “We get people who know about it and come for that reason.” Continue reading...
