Greenhouse gases rise to record high in 2010: UN
The amount of global warming-causing greenhouse gases in the atmosphere rose to a new high in 2010, and the rate of increase has accelerated, the UN weather agency said on Monday.
Levels of carbon dioxide -- a greenhouse gas and major contributor to climate change -- rose by 2.3 parts per million between 2009 and 2010, higher than the average for the past decade of 2.0 parts per million, a new report by the World Meteorological Organisation found.
"The atmospheric burden of greenhouse gases due to human activities has yet again reached record levels since pre-industrial time," said WMO Secretary-General Michel Jarraud.
Greenhouse gases trap radiation within the earths atmosphere, causing it to warm.
The last two decades have seen a 29 percent increase in radiative forcing -- the warming effect -- from greenhouse gases, the report said.
Scientists attributed the continuing rise in levels of carbon dioxide, which contributes about 64 percent to climate warming, to fossil fuel burning, deforestation and changes in land use.
Methane, produced by cattle-rearing and landfills, is the second most important greenhouse gas after carbon dioxide, followed by nitrous oxide.
The WMO's annual Greenhouse Gas Bulletin said methane levels rose 5 parts per billion or 0.28 percent in 2009-2010 after a period of relative stabilisation from 1999 to 2006, possibly due to the thawing of the Northern permafrost and increased emissions from tropical wetlands.
Nitrous oxide, emitted into the atmosphere from natural and man-made sources, including biomass burning and fertiliser use, rose 0.8 parts per billion to 323.2 in 2010 -- 20 percent higher than in the pre-industrial era, defined as the period before 1750.
Its impact on the climate over a 100-year period was said to be 298 times greater than equal emissions of carbon dioxide.
"Even if we managed to halt our greenhouse gas emissions today -- and this is far from the case -- they would continue to linger in the atmosphere for decades to come and so continue to affect the delicate balance of our living planet and our climate," said Jarraud.
"Now more than ever before, we need to understand the complex, and sometimes unexpected, interactions between greenhouse gases in the atmosphere, Earths biosphere and oceans."
The seventh Greenhouse Gas Bulletin comes ahead of a new round of UN climate talks in South Africa next Monday, testing global resolve to tackle what scientists warn is a time bomb with an ever-shorter fuse.
Analysts say the UN process is still traumatised by the near-collapse of the 2009 Copenhagen Summit and, in Durban, faces a bust-up over the Kyoto Protocol, the only agreement setting legal curbs on greenhouse gases.
Data from the US Department of Energy released earlier this month showed carbon emissions from burning fossil fuels made their biggest ever annual jump in 2010, led by China, the United States and India.

More likely it will fund vast institutions of social control to prepare the poor nations for concerted domination and scientifically planned resource extraction.
Anyone delusional enough to expect altruism and humanity from this band of jackals should be the first to submit to their "population control" regimes.
For years the mad-hatter climate kooks were merely a sad offshoot of anti-human nihilism until the big money groups figured out how to turn their hysteria into a fast track for global domination.
For us to accept these plans would be to utterly abandon our reason.

The Co2 is higher Co2 residence in the atmosphere is between 5 and 15 years, the temperature increase has stalled since 1998. even the most alarmist warmist doom and gloomier scientist agree with this, that's why they now want a 17 year stable or slight cooling before acknowledgement of a cycle warm cool or static.
Ben Santer, said that tropospheric temperature records must be at least 17 years long to discriminate between internal climate noise and the signal of human caused changes.
Whats magic about 17 years instead of 15? From their point of view,
it would give the alarmists at least two more years of grace before they had to admit the giant computer models are a total failure.
That might be enough time to re-elect Obama.

How long until it gets to that point where it can contain no more? Probably never.
When we consider that CO2 was in levels of several 1000s ppm in the distant past, and life figured out a way to deal with it, I see no reason why that cannot happen again.
There is no way that mankind will ever be able to burn everything that became buried as they cannot get to it all (a lot of it has been subducted under continental plates many times over), so the levels will never reach that height again from man's burning of fossil fuels. It is a physical impossibility.
The oceans held it in, then. They will most likely do it again, with the additional support of not having the levels of the gas raised as high as they were by humans.

Snow cover will vary from year to year.

It boggles the mind that you still fail to comprehend the very basics of the science you endeavor to criticize and reject.

This is fallacy. Your not getting the big picture here Skepticus. The reason why we would like to keep Co2 to 450ppm preferably less is this only amounts to a global average temperature rise of 1.7C from 1990. If you double that, then models predict doubling of the temp. Why you and I can probably "put up" with a 2C increase, trees, plants, animals, fish, reefs and whole ecosystems could easily be wiped out. There is no guarantee your going to like the results.
If you look at the projections (yeah computer models to the deniers) it does not look good for man kind. Even cooler climates could be susceptible to man effects of a warmer environment.

You are assuming that the models are correct. So far, they have been way off. If you take the land temperatures only, it has not warmed significantly since 2001. If you take the land and sea global average temperatures, there is a slight downward trend since 2001. Either way, the warming has not been significant for the entire decade. In addition, the models were off, reality being only 40% of what was predicted by the models.
When I see a real warming trend, it will then be time to calculate risk premiums and so forth. We will have to wait and see what happens over the next two to three decades to be sure about anything relative to temperatures. That it how long it will take to see whether we are on target for long-term cooling or we have no more than noise as part of a long-term warming. I believe in patience rather than alarmism.

The models have been inaccurate. You should do some experiments with CO2. I have several for you to try, all of which have one or more controls. I have yet to replicate empirically what the models say will happen. I and friends have been trying to get as many people to try to do these experiments as possible. The one thing that has been a constant is that nearly every alarmist who does the experiments gets angry and refuses to share their results with either us or the public.

Overall, using global average combined land and sea surface temperatures, it hasn't really warmed since 2001. What is there to explain? And, don't try to invoke BEST. That data only covers land data and does not include anything else--which makes it not so global a data set, considering that the earth is about 70% ocean.
The models in AR4 were not correct. Reality is at only just under 40% of what the models predicted. That leaves a margin of error of over 60%. That is why research is ongoing to improve the models and include weather and climate elements that are not accurately portrayed in the models. You need to keep up with the flow of information, and read some papers. You might need a paid subscription for some of them, however. Not all of them are available for free.

I forgot to address this. Just so you know in advance, I have been told by someone I know that there are groups who have been studying ocean pH, following up in oceans where samples were previously taken that showed declines in pH in published papers. I cannot say much in public about this other than to mention that it is happening.
The only thing I will say further about this is that a number of samples in several locations taken this year are showing increases in pH since the samples were last taken. That is all I am saying about it. When the work is finished and the work completed, I am sure that all will be made public eventually. You can then read more about it then.
Who knows, maybe overall the data still will lean toward supporting your side of the argument. We'll see. :)

The media has made it a concern. The trouble is, if more samples turn up a higher pH in a wider array of samples, thus showing increasing pH of the various oceans being tested, the whole idea of ocean acidification goes out the window.
And, who cares what the oil companies think? I certainly don't.
No, not for the last decade and are stagnating rather than accelerating. The data entire globe together and there is no accelerated warming for the last decade.
