Warmer seas fuel Maine crab invasion, clammers say
2013-05-30 22:22:00| Climate Ark Climate Change & Global Warming Newsfeed
Reuters: An invasion of European green crabs, encouraged by rising ocean temperatures, is eating its way north through Maine's clam flats, threatening the state's third-largest fishery and an iconic summer treat for tourists. "If something isn't done soon, it will mean the death of the clam fishery," said Chad Coffin, president of the Maine Clammers Association. "I don't think people understand just how big a problem this is." The invasive crabs likely reached U.S. shores in the early 1800s after hitching...

Last time CO2 hit 400 ppm, temperature was 8C warmer, seas 40m higher than today

Guardian: Lake sediments recorded the climate of the Arctic during the last period when CO2 levels were as high as today The future of a globally warmed world has been revealed in a remote meteorite crater in Siberia, where lake sediments recorded the strikingly balmy climate of the Arctic during the last period when greenhouse gas levels were as high as today. Unchecked burning of fossil fuels has driven carbon dioxide to levels not seen for 3m years when, the sediments show, temperatures were 8C higher...
Warmer Climate Threatens Africas Vital Cassava Crop

Climate News Network: A plant which is a staple food crop for millions of people across Africa is at risk from disease as regional temperatures rise, scientists say. The plant, cassava, is a significant source of food and income, and is an important industrial crop, and there is concern that serious food shortages may result and poverty worsen. Experts say the spread of the disease could halve cassava production and threaten the diets of 300 million people. Experts say the spread of the disease could halve cassava...

Great tits unaffected by warmer springs
2013-04-28 19:46:00| Climate Ark Climate Change & Global Warming Newsfeed
Mongabay: The population of a widely dispersed bird species is relatively unaffected by warmer springs, indicating that some species may be adapting to shifts caused by climate change, reports a study published in the journal Science. The research assessed the impact of earlier springs on a well-studied population of great tits, a bird that ranges across Europe, the Middle East, Central and Northern Asia, and North Africa. The study found that while the availability of the main food source for great tit...

Warmer Seas May Impact Antarctic Clams Reproduction
2013-04-28 17:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Climate News Network: Antarctic clams (Laternula elliptica) play a vital role in the ocean ecosystem, drawing down carbon into sea-bed sediments and circulating ocean nutrients. Now a new study has found that the reproductive capacity of this long-lived and abundant species -- existing in the cold, oxygen-rich waters of the Antarctic -- could be seriously affected by rising ocean temperatures. The study, by scientists at the British Antarctic Survey (BAS) and from the University of Kiel and the Alfred Wegener Institute...
