This articles demonstrates several things that I have long argued, but people said I was nuts. While global warming is scary its not the scariest thing going on. The globe should be cooling. By now we should down 1 degree faranheit (used throughout) at the equator and maybe 4 or 5 degrees at the poles. This discrepancy is really really frightening because it raises the chances that we will lose control entirely and the climate will “tip” or go haywire. And in fact you see a little of that already with the equator up a full degree but the poles are up 8 degrees in some places.
So instead of shrinking, our glaciers should be growing and our supply of fresh drinking water should go up as the cold rains fall as the oceans evaporate a tad. The ocean should be dropping a bit as should our food production (yah I know bummer). But tell that to Georgia, Florida, and Alabama. Why is this so dangerous. Well because the cooling that should be happening will not happen uniformly, there should be heat spikes and since the global cooling is being masked by the warming we won’t know in advance when that happens. But when it does in will exponentially hammer the environment.
In addition this article also makes the point that a warm ocean will cease to accept carbon. The single largest carbon sink we have, the bottom of the pacific ocean, will quit working and then, well, we are done. In fact, in the latest edition of National Geographic they claim that the Earth is currently at 380 parts/mill. of carbon above a baseline for the planet at about 250 parts/mill. It further argues that things will get really bad around 450 parts/mill. This article argues that we are ALREADY THERE!
Study: Carbon dioxide increasing faster than expected in atmosphere

WASHINGTON – Just days after the Nobel prize was awarded for global wanning work, an alarming new study finds that carbon dioxide in the atmosphere is increasing faster than expected.
Carbon dioxide emissions were 35 percent higher in 2006 than in 1990, a much faster growth rate than anticipated, researchers led by Josep G. Canadell, of Australia’s Commonwealth Scientific and Industrial Research Organization, report in today’s edition of Proceedings of the National Academy of Sciences.
Increased industrial use of fossil fuels coupled with a decline in the gas absorbed by the oceans and land were listed as causes of the increase.
“In addition to the growth of global population and wealth, we now know that significant contributions to the growth of atmospheric C02 arise from the slowdown” of nature’s ability to take the chemical out of the air, said Canadell, director of the Global Carbon Project at the research organization.
The changes “characterize a carbon cycle that is generating stronger-than-expected and sooner-than-expected climate forcing,” the researchers report.
Kevin Trenberth of the climate analysis section of the National Center for Atmospheric Research in Boulder, Colo, said the “paper raises some very important issues that the public should be aware of: Namely that concentrations of C02 are increasing at much higher rates than previously expected, and this is in spite of the Kyoto Protocol that is designed to hold them down in western countries.”
Alan Robock, associate director of the Center for Environmental Prediction at Rutgers University, added: “What is really shocking is the reduction of the oceanic C02 sink,” meaning the ability of the ocean to absorb carbon dioxide, removing it from the atmosphere.
The researchers blamed that reduction on changes in wind circulation, but Robock said he also thinks rising ocean temperatures reduce the ability to take in the gas.
“Think that a warm Coke has less fizz than a cold Coke,” he said.
Neither Robock nor Trenberth
was part of Canadell’s research team.
Carbon dioxide is the leading “greenhouse gas,” so named because their accumulation in the atmosphere can help trap heat from the sun, causing potentially dangerous warming of the planet.
While most atmospheric scientists accept the idea, finding ways to reduce greenhouse gas emissions has been a political problem because of potential effects on the economy.
Earlier this month, the Nobel Peace Prize was awarded to the United Nations Intergovernmental Panel on Climate Change and former Vice President Al Gore for their work in calling attention to global warming.
“It turns out that global warming critics were right when they said that global climate models did not do a good job at predicting climate change,” Robock commented: “But what has been wrong recently is that the climate is changing even faster than the models said.
In fact, Arctic sea ice is melting much faster than any models predicted, and sea level is rising much faster than IPCC previously predicted.”
According to the new study, carbon released from burning fossil
fuel and making cement rose from 7.0 billion metric tons per year in 2000 to 8.4 billion metric tons in 2006. A metric tons is 2,205 pounds.The growth rate increased from 1.3 percent per year in 1990-1999 to 3.3 percent per year in 2000-2006, the researchers added.
Trenberth noted that carbon dioxide is not the whole story — methane emissions have declined, so total greenhouse gases are not increasing as much as carbon dioxide alone.
Also, he added, other pollution plays a role by cooling.
There are changes from year to year in the fraction of the atmosphere made up of carbon dioxide and the question is whether this increase is transient or will be sustained, he said.
“The theory suggests increases in (the atmospheric fraction), as is claimed here, but the evidence is not strong,” Trenberth said.
The paper looks at a rather short time to measure a trend, Robock added, “but the results they get certainly look reasonable, and much of the paper is looking at much longer trends.”
