-From pizzly bears to strange fish, here’s why hybrid animal sightings are on the rise [[https://kraken12web.com|kraken официальный сайт]]
+UK project trials carbon capture at sea to help tackle climate change [[https://kra34c.cc/|kra34.cc]]
-The bear scientists shot in the Canadian arctic in 2016 was a biological mystery. It looked like a grizzly bear, complete with long claws and a prominent snout, but most of its fur was white.
+The world is betting heavily on carbon capture — a term that refers to various techniques to stop carbon pollution from being released during industrial processes, or removing existing carbon from the atmosphere, to then lock it up permanently.
-Call it a pizzly or maybe a grolar bear. Either way, scientists determined the animal was the rare offspring of a polar bear that mated with a grizzly, and as the Arctic melts and polar bears increasingly move on land, sightings of these hybrids are on the rise.
+The practice is not free of controversy, with some arguing that carbon capture is expensive, unproven and can serve as a distraction from actually reducing carbon emissions. But it is a fast-growing reality: there are at least 628 carbon capture and storage projects in the pipeline around the world, with a 60% year-on-year increase, according to the latest report from the Global CCS (Carbon Capture and Storage) Institute. The market size was just over $3.5 billion in 2024, but is projected to grow to $14.5 billion by 2032, according to Fortune Business Insights.
-Pizzly bears aren’t being born en masse, said Charlotte Lindqvist, a biology professor at the University of Buffalo whose lab focuses on evolutionary genetics. The accounts of the bears are mostly anecdotal, and it’s unclear how widespread the phenomenon is.
+Perhaps the most ambitious — and the most expensive — type of carbon capture involves removing carbon dioxide (CO2) directly from the air, although there are just a few such facilities currently in operation worldwide. Some scientists believe that a better option would be to capture carbon from seawater rather than air, because the ocean is the planet’s largest carbon sink, absorbing 25% of all carbon dioxide emissions.
-For instance, eight of the bear hybrids were found to be the children of a particular female polar bear with a seeming proclivity for male grizzlies.
+In the UK, where the government in 2023 announced up to £20 billion ($26.7 billion) in funding to support carbon capture, one such project has taken shape near the English Channel. Called SeaCURE, it aims to find out if sea carbon capture actually works, and if it can be competitive with its air counterpart.
-But as global temperature rises and Arctic ice melts, polar bears will have more chances to encounter – and mate with – other bear species.
+“The reason why sea water holds so much carbon is that when you put CO2 into the water, 99% of it becomes other forms of dissolved carbon that don’t exchange with the atmosphere,” says Paul Halloran, a professor of Ocean and Climate Science at the University of Exeter, who leads the SeaCURE team.
-“This might just be the beginning,” Lindqvist told CNN. “The pressure is on, and we can clearly see in certain areas polar bears are spending more time on land as the sea ice is disappearing. Brown and black bears are encroaching on more Arctic habitat. And I think that’s just going to expand.”
+“But it also means it’s very straightforward to take that carbon out of the water.”
+Pilot plant
+SeaCURE started building a pilot plant about a year ago, at the Weymouth Sea Life Centre on the southern coast of England. Operational for the past few months, it is designed to process 3,000 liters of seawater per minute and remove an estimated 100 tons of CO2 per year.
+“We wanted to test the technology in the real environment with real sea water, to identify what problems you hit,” says Halloran, adding that working at a large public aquarium helps because it already has infrastructure to extract seawater and then discharge it back into the ocean.
+The carbon that is naturally dissolved in the seawater can be easily converted to CO2 by slightly increasing the acidity of the water. To make it come out, the water is trickled over a large surface area with air blowing over it. “In that process, we can constrict over 90% of the carbon out of that water,” Halloran says.
