Lean times lie ahead for fishermen in California and Oregon. Last week, US regulators decided to cancel the entire salmon season for this year. The long-term prospects for the salmon themselves are unclear. In the long term, however, the future of the salmon, and the people that rely on them, may depend on climate change.
Ocean acidification in response to rising atmospheric CO2 partial pressures is widely expected to reduce calcification by marine organisms. From the mid-Mesozoic, coccolithophores have been major calcium carbonate producers in the world's oceans, today accounting for about a third of the total marine CaCO3 production. Here, the researchers present laboratory evidence that calcification and net primary production in the coccolithophore species Emiliania huxleyi are significantly increased by high CO2 partial pressures.
Almost 6 years ago, a paper in Science warned of an unheralded environmental peril. Melted snow and ice seemed to be reaching the base of the great Greenland ice sheet, lubricating it and accelerating the sheet's slide toward oblivion in the sea, where it was raising sea level worldwide (12 July 2002, p. 218). Now a two-pronged study-both broader and more focused than the one that sounded the alarm-has confirmed that meltwater reaches the ice sheet's base and does indeed speed the ice's seaward flow. The good news is that the process is more leisurely than many climate scientists had feared.
Past atmospheric methane concentrations show strong fluctuations in parallel to rapid glacial climate changes in the Northern Hemisphere, superimposed on a glacial
When people talk about catastrophic climate change, there's a fair chance that Greenland is on their mind. If they use the term 'tipping point', then it is pretty much a sure thing. One-twentieth of the world's ice is locked up atop that island, and if it were to melt completely, global sea levels would rise by seven metres. The collapse of the Greenland ice sheet is in the front rank of potential climate catastrophes.

Planet Ark April 15, 2008 Melting Mountains A "Time Bomb" For Water Shortages AUSTRIA: April 15, 2008 VIENNA - Glaciers and mountain snow are melting earlier in the year than usual, meaning the water has already gone when millions of people need it during the summer when rainfall is lower, scientists warned on Monday. "This is just a time bomb," said hydrologist Wouter Buytaert at a meeting of geoscientists in Vienna.
