The reason some popular posts are tagged ‘no title’ is not because they have no title—they all do—but because the old Blogger embedded the title at the top of text, and the new software does not see that. You can see the titles in capitals at the start of each snippet. (It would be nice if Blogger introduced an upgrade program that could fix this little problem.)

A new study, reported in ScienceDaily has for the first time used hard data to measure the level at which the oceans are absorbing carbon-dioxided, and found a significant reduction.

"Researchers have used climate models that suggest the oceans have been absorbing less CO2, but this is the first study to quantify the change directly using observations," said the author of the study, Jeffrey Park, who is professor of geology and geophysics and director of the Yale Institute for Biospheric Studiesthe Park. "It strengthens the projection that the oceans will not absorb as much of our future CO2 emissions, and that the pace of future climate change will quicken."

He used data collected from atmospheric observing stations in Hawaii, Alaska and Antarctica to study the relationship between fluctuations in global temperatures and the global abundance of atmospheric CO2 on interannual time scales (one to 10 years). A similar study done 20 years ago found a five-month lag between interannual temperature changes and the resulting changes in CO2 levels. Park found that the lag has increased to at least fifteen months, a surprisingly large change, which indicates that the ability of the oceans to absorb carbon-dioxide is much reduced.
