NOTE ON POPULAR POSTS

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.)

OCEANS NOW ABSORBING CO2 MORE SLOWLY

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.

NASA SEES UNEXPECTED ANTARCTIC ICE-LOSS

ScienceDaily reports satellite measurements by NASA showing an unexpected, and large, loss of ice in East Antarctica, an area that holds 90% of the world's fresh water, and was previously thought stable.

West Antarctica is losing 132 gigatonnes of ice a year. Now East Antarctica is estimated to be losing 57 gigatonnes a year. (A gigatonne is a billion metric tons.)

CARBON-DIOXIDE EMISSIONS UP 29 PERCENT

A report in ScienceDaily says that atmospheric CO2 emissions have risen 29% since 2000 and 41% between 1990 and 2008. 1990 is the reference year for the Kyoto Protocol...

Another report, on a study that has for the first time measured the greenhouse-strength of a range of other chemicals, some of which last for thousands of years in the atmosphere, found that they have far greater heat-trapping power than carbon-dioxide.

HOTTER AMERICA AND GREENLAND MELTING FASTER

Two reports from ScienceDaily show that the Greenland icesheet is losing mass at an accelerating rate, and that record high temperatures across the United States are far outpacing lows.
