oh come on, ionus. Your cite does NOT support you, In fact it trashes your whole argument. Did you read antything beyond the headline? Apparently not. There is a difference between some slowing down of uptake, which it says may b e happening, and your position, which seems to be that the oceans are outgassing the carbon dioide they have taken in in the past. Read it again (or for the first time). It blows you out of the water (which the oceans aren't doing to CO2).
Quote: Atmospheric levels of carbon dioxide are rising at a record rate as fossil fuel consumption increases and the ability of the oceans to absorb the greenhouse gas diminishes, the World Meteorological Organisation said.
Average levels of C02 in the atmosphere rose almost 3 parts per million to 396 in 2013, accelerating from the 2.2 ppm increase in the previous year, the UN body said, citing data from 125 monitoring sites worldwide.
"The changes we're seeing are really drastic," Oksana Tarasova, a scientist and chief of the WMO's Global Atmospheric Watch program told The Washington Post. "We are seeing the growth rate rising exponentially."
Atmosphere levels of C02 are now 42 per cent higher than they were in 1750, before the industrial revolution and the subsequent surge in consumption of oil, coal and gas, and increased land-clearing for agriculture and other human activities.
The atmospheric CO2 concentration has not been this high in at least 800,000 years, with the warming effect on the climate rising 34 per cent since 1990, the WMO said.
Two other key greenhouse gases, methane and nitrous oxide are 253 per cent and 121 per cent higher, respectively, since 1750.
The WMO report also contained details on the increased acidification of the world's oceans, noting the level is "unprecedented" over the past 300 million years.
"The ocean's acidity increase is already measurable as oceans take up about 4 kilograms of CO2 per day per person," the report said.
Katrin Meissner, an oceanographer and climate modeller at the University of NSW, said physical and biological processes under way will curb the ability of oceans to absorb C02, leaving more of it in the atmosphere.
The warming of the ocean surface reduces its ability to take up more CO2 as does its increased acidity, Professor Meissner said.
Since the warmer surface waters are lighter, there is less exchange with the deeper ocean, which also reduces the absorption ability. In turn, the reduced mixing of waters will mean fewer nutrients will be brought to the surface, altering the ecology of the seas and reducing the biological uptake of carbon, she said.
"The prediction is that all three [processes] are going to slow down," Professor Meissner said.
Slowing uptake
Michael Raupach, formerly of the CSIRO and now at the Australian National University, said land and oceans take up about half of all CO2 emissions and help show the pace of global warming.
Despite some year-to-year variability, particularly on land, a pattern is emerging over decades suggesting the sinks "are not keeping pace with rising CO2 concentrations in the atmosphere", Professor Raupach said.
"This is partly a sign that the efficiencies of the all-important land and ocean CO2 sinks are weakening," he said.
You will notice, if you are honest, Ionus, that your cite says that global warming IS taking place. A position you have been denigrating. Good work, Ionus, your own sources prove you're more full of hot air than the changing atmosphere is. And that's a lot.
