From raw measurements we know that in recent years the oceans seem to take up a smaller percentage of the CO2 we emit. Analysing available data a group of three researchers finds in part of the North Atlantic this is … Continue reading
The cumulative effect of environmental threats like climate change, ocean acidification and overfishing, brings the world’s interconnected ocean close to a phase of extinction of marine species that is ‘globally significant’ and unprecedented in human history, an international panel of … Continue reading
For the layman paleoclimatology is ‘proof’ that any climate change is natural. For educated thinkers the lessons from the long ago contain the biggest warnings for the current artificially created state of our planet.
And already suffer biodiversity losses during the decline from pH 8.1 (preindustrial) to 7.8. That latest number is the expected acidification for the end of this century according to IPCC 4AR, a theoretical scenario and a dangerously often quoted underestimation … Continue reading
1998: 58% coral reefs threatened 2011: 75% coral reefs threatened 2030: 90% coral reefs threatened 2050: 100% coral reefs threatened
There is some big climate news under way. Negotiators in Cancún however can consider themselves fortunate that it will be at least another month before NASA scientists can announce their findings: 2010 will be the hottest year on record.
Cold water absorbs more CO2, so it is around the Poles that the consequences of ocean acidification are first felt. Pteropods – tiny swimming Arctic sea snails – have difficulty building their shells at CO2 levels very close to the … Continue reading
A publication in next week’s edition of PNAS magazine elaborates on the effects of continued acidification of ocean waters on shellfish. Larvae of two species of shellfish commonly found along the American East Coast (Northern quahog and Atlantic bay scallop) … Continue reading
