“Ocean acidification could cause fish to become “fatally attracted” to their predators, according to scientists.
A team studying the effects of acidification – caused by dissolved CO2 – on ocean reefs found that it leaves fish unable to “smell danger”.
Young clownfish that were reared in the acidified water became attracted to rather than repelled by the chemical signals released by predatory fish.” “Acid oceans leave fish at more risk from predators“
“Melting of the Arctic sea ice due to global warming is diluting surface waters and this is endangering some species of shellfish which need minerals in the water to form their shells and skeletons, scientists have found.
In a paper published in Science, they warned that this has serious implications for ecosystems in the Arctic.
“Organisms that are likely to be affected are from the family of pteropods, also mussels and clams on the sea floor,” said Fiona McLaughlin, research scientist at Canada’s Institute of Ocean Sciences’s department of fisheries and oceans. …
“It puts the food chain at risk. These organisms are a food source for fish that are a food source for seals and bears. The food chain in the Arctic is quite a short one, so it’s quite vulnerable,” she told Reuters by telephone.” “Melting Sea Ice Dilutes Water, Endangers Sea Life“
“Global warming is happening faster than expected and at worst could raise sea levels by up to 2 meters (6-1/2 ft) by 2100, a group of scientists said on Tuesday in a warning to next month’s U.N. climate summit in Copenhagen.
In what they called a “Copenhagen Diagnosis,” updating findings in a broader 2007 U.N. climate report, 26 experts urged action to cap rising world greenhouse gas emissions by 2015 or 2020 to avoid the worst impacts of climate change.
“Climate change is accelerating beyond expectations,” a joint statement said …” “Climate Change Quickens, Seas Feared Up 2 meters“
“Since the 1997 international accord to fight global warming, climate change has worsened and accelerated — beyond some of the grimmest of warnings made back then.
As the world has talked for a dozen years about what to do next, new ship passages opened through the once frozen summer sea ice of the Arctic. In Greenland and Antarctica, ice sheets have lost trillions of tons of ice. Mountain glaciers in Europe, South America, Asia and Africa are shrinking faster than before. …
Even the gloomiest climate models back in the 1990s didn’t forecast results quite this bad so fast.
“The latest science is telling us we are in more trouble than we thought,” Janos Pasztor, climate adviser to UN Secretary General Ban Ki-moon.” “Warming’s Impacts Sped up, Worsened Since Kyoto“
“The effects of climate change have driven women in communities in coastal areas in poor countries like the Philippines into dangerous work, and sometimes even the flesh trade, a United Nations official said.
Suneeta Mukherjee, country representative of the United Nations Food Population Fund (UNFPA), said women in the Philippines are the most vulnerable to the effects of climate change in the country.
“Climate change could reduce income from farming and fishing, possibly driving some women into sex work and thereby increase HIV infection,” Mukherjee said during the Wednesday launch of the UNFPA annual State of World Population Report in Pasay City.” “‘Climate change pushes poor women to prostitution, dangerous work’“
