Study: Climate change could be a boon for crayfish and other freshwater creatures

British rivers could be set for an explosion of crayfish and other crustaceans as global warming pushes up inland water temperatures, new research predicts.

While similar sea-based species are set to suffer from climate change, their freshwater counterparts are likely to benefit from a warmer habitat.

Previous research involving land-based vertebrae has found that the diversity of a species tends to increase with warming and that this is a general trend across habitats.

The new study by the University of Bath, however, is the first to find that the reaction of a species to climate change is dependent on its habitat.

The phenomenon could mean a bonanza for numbers of freshwater anomura.

This is the first research to suggest that species response to climate change, whether warming or cooling, could be habitat dependentDr Katie Davis, University of Bath

The white-clawed crayfish is the UK’s only native crayfish species and is currently protected by law because of an 80 per cent decline in the last 10 years due to the presence of invasive, non-native creatures such as the American Signal crayfish.

Otherwise known as freshwater lobster, the crustacean is frequently served in soups, bisques, etoufflees, where often only the tail portion is eaten.

The Bath researchers say the maritime equivalent species, such as hermit crabs, king crabs and squat lobsters, will not see a similar benefit from global warming.

This is because changing sea levels will negatively affect the amount of shelf habitat available to the creatures, which are predominantly shallow shelf dwellers.

Dr Katie Davis, who led the study, which is published in the journalNature Communications, said: “While other research found that species diversity increased with global warming, our findings suggest that this is not a universal rule.

“We find that the freshwater group follow this pattern, but their marine relatives show the opposite.

“This is the first research to suggest that species response to climate change, whether warming or cooling, could be habitat dependent.”

‘Global warming not the culprit’: Glaciers of Yosemite National Park are NOT disappearing from climate change

Yet Yosemite geologist Greg Stock and naturalist Pete Devine said their research does not show that global warming is behind the melting glaciers, despite increased greenhouse gases. Devine and Stock say the glaciers that still remain in the park—a remnant from the last glaciation over 15,000 years ago—are responsible for the park’s iconic landscapes. Over time, the glaciers have created such formations as El Capitan, the Half Dome, and the Yosemite Valley that brings in visitors from around the world.

During the last glaciation, 75 percent of Yosemite was covered by behemoth-sized glaciers, which carved up and scored the ground, chiseling out the park’s smooth granite. But the two largest glaciers, Lyell and Maclure, may be gone in few decades. Devine believes Lyell glacier, named after the eighteenth-century geologist Charles Lyell, will be a “corpse” in 20 years. But should natural changes in natureget blamed on global warming?

Disappearing Yosemite glacier becomes symbol of climate change

Lyell Glacier in Yosemite National Park has shrunk by 78 percent over the past 130 years, becoming a vivid example of the destructive effects of climate change.

Moving like a glacier

When Muir described the glaciers of Yosemite he was mocked by the ‘consensus’geologists who said he had only discovered ice fields and not actual glaciers. So Muir and Galen Clark, a Yosemite Park supervisor, devised a #Science project. They planted five stakes in Maclure Glacier and returned after a month and a half. Muir found all the stakes had moved and one had traveled nearly 47 inches. That was in 1875. Muir also noted the Lyell Glacier was less than a mile long and probably had an original length of over forty miles during the last glaciation.

Four years ago, Stock, Devine and Robert Anderson (a geologist) repeated Muir’s stake test in the Lyell and Maclure Glaciers. When they came back, there was no movement of the Lyell Glacier. But the Maclure Glacier was moving roughly one inch per day, the same speed John Muir wrote about in 1875. Despite the climate change hype, things were happening at the same speed as 150 years ago.

German Lawmakers Vote to Ban the Internal Combustion Engine

The modern internal combustion engine first came from Germany and now Germany wants to put a nail in its coffin. The Bundesrat has passed a resolution to ban the ICE beginning in 2030.

Germany’s Spiegel Magazin reported this morning that the country’s top legislative body was able to reach a bi-partisan agreement that hopes to allow only zero-emission vehicles on EU roads in 14 years. For the resolution to be instituted across Europe, it will have to be approved by the EU. But according to Forbes, “German regulations traditionally have shaped EU and UNECE regulations.”

Greens party lawmaker Oliver Krischer told Spiegel, “If the Paris agreement to curb climate-warming emissions is to be taken seriously, no new combustion engine cars should be allowed on roads after 2030.”…
