Carbon in the atmosphere is increasing, at the same time the two biggest natural processes that capture carbon from the atmosphere: biomass production, and the ocean sink, are falling down on the job.
I'm not getting a happy feeling over this news.
That sinking feeling in my stomach, I'm not sure enough people share it yet.
There is a lot of hot air while politicians weasel out from under the most modest of CO2 caps... (I'm not even speaking of the Dutch who are so deep in denial they need snorkels!)
Human activities are releasing carbon dioxide faster than ever, while the natural processes that normally slow its build up in the atmosphere appear to be weakening. These conclusions are drawn in a new study in the early online edition of the Proceedings of the National Academy of Sciences,* October 22-26. The report states that “together, these effects characterize a carbon cycle that is generating stronger-than-expected climate forcing sooner than expected.”
Between 2000 to 2006, human activities such as burning fossil fuels, manufacturing cement, and tropical deforestation contributed an average of 4.1 billion metric tons of carbon to the atmosphere each year, yielding an annual growth rate for atmospheric carbon dioxide of 1.93 parts per million (ppm). “This is the highest since the beginning of continuous monitoring in 1959,” states the report. The growth rate of atmospheric carbon dioxide is significantly larger than those for the 1980s and 1990s, which were 1.58 and 1.49 ppm per year, respectively. The present atmospheric concentration of carbon dioxide is 381 ppm, the largest concentration in the last 650,000 years, and probably in the last 20 million years.
While the worldwide acceleration in carbon dioxide emissions had been previously noted, the current analysis provides insights into its causes. “The new twist here is the demonstration that weakening land and ocean sinks are contributing to the accelerating growth of atmospheric CO2,” says co-author Chris Field, director of the Carnegie Institution’s Department of Global Ecology.
Changes in wind patterns over the Southern Ocean resulting from human-induced global warming have brought carbon-rich water toward the surface, reducing the ocean’s ability to absorb excess carbon dioxide from the atmosphere. On land, where plant growth is the major mechanism for drawing carbon dioxide out of the atmosphere, large droughts have reduced the uptake of carbon.
Emissions from the burning of fossil fuels constituted the largest source of anthropogenic carbon, releasing an average of 7.6 billion metric tons each year between 2000 and 2006, a significant jump from 6.5 billion tons in the 1990s. Emissions generated by land-use changes such as deforestation have remained constant, but shifted in geographic focus.
The study also shows that the carbon intensity of the global economy (kilograms of carbon per dollar of economic activity) has increased since 2000 at about 0.3% per year, reversing a 30-year decline of about 1.3% per year. Because practically all proposed scenarios for managing future emissions postulate improvements in carbon intensity in the global economy, this deterioration of carbon intensity presents a serious challenge in stabilizing atmospheric carbon dioxide and mitigating climate change.

There is no easy way around this. A few light bulbs and hybrid cars won't cut it.
We need harsh measures and we need to curtail industry.
Who will tell industry this, you think?
Who will ever be able to enforce this?
No politician, that's for sure. The democratic system of elections make this quite much impossible to do. I'm rather attached to democracy, I'd not want to see it go.
I really don't see a way out.
