UN Study Shows Record-High Increases For Atmospheric CO2 In 2013

Figures released Tuesday by a United Nations advisory body reveal that 2013 saw new recorded highs for both carbon dioxide and methane, as well as the largest year-over-year rise in carbon dioxide since 1984, reflecting continuing worldwide emissions from human sources but also the possibility that natural sinks (oceans and vegetation) are near their capacity for absorbing the excess. From the Washington Post's account: The latest figures from the World Meteorological Organization’s monitoring network are considered particularly significant because they reflect not only the amount of carbon pumped into the air by humans, but also the complex interaction between man-made gases and the natural world. Historically, about half of the pollution from human sources has been absorbed by the oceans and by terrestrial plants, preventing temperatures from rising as quickly as they otherwise would, scientists say. “If the oceans and the biosphere cannot absorb as much carbon, the effect on the atmosphere could be much worse,” said Oksana Tarasova, a scientist and chief of the WMO’s Global Atmospheric Watch program, which collects data from 125 monitoring stations worldwide. The monitoring network is regarded as the most reliable window on the health of Earth’s atmosphere, drawing on air samples collected near the poles, over the oceans, and in other locations far from cities and other major sources of pollution. The new figures for carbon dioxide were particularly surprising, showing the biggest year-over-year increase since detailed records were first compiled in the 1980s, Tarasova said in an interview. The jump of nearly three parts per million over 2012 levels was twice as large as the average increase in carbon levels in recent decades, she said.

Indeed, in a few years, they'll be emitting as much per capita as Germany 9.5t, the UK 7.7t and the US 17.5t

t=tonnes of CO2 per annum per capita..

I'm no fan of China's pollution 7t record but it seems odd to single them out.

Ocean acidification is scary

[MyNicknameSucks]

Higher acidity [CO2 dissolved in water forms an acid] in seawater is known to disrupt the life cycles of many marine species — from reef-building corals to shellfish beloved by humans — by interfering with the creatures’ ability to use sea-borne calcium to build their shells.

This bit should be scaring the pants off us. Not because we'll suddenly not be feasting on oysters, but because of zooplankton that form delicate calcium-based shells. If those critters go bye-bye, we will likely see the collapse of more ocean fisheries as food sources dry up.

And, in something of a double-whammy, coastal regions in the tropics are often protected by reefs from the ravages of some tropical storms. If those reefs slow down their growth (that replaces damaged reefs structures), or start dissolving, we're going to be have a tidal wave (bad pun!) of starving refugees.

You don't need to believe in global warming to see those two issues becoming problems. You need enough empathy to see this as being a problem, even if it's not in your own backyard.

If you do believe in global warming, it's a crapshoot as to whether or not the oceans will rise high enough to wipe out their homes before acidification lays a licking on marine ecosystems.
