US GDP is largely generated by financial activities. Whereas the Chinese GDP is based more on the sale of manufacturing products ... in the USA in particular, which also exploits them for the local GDP.

So for sure, there is distortion. But no graph is perfect.

Tssss ... it seems to me obvious that this statistic is piped up, when one agrees to look at the real standard of living of the Chinese (in terms of consumption means) as, for example, the possession of private vehicles:

If you add the principle of the carbon footprint to the polluter-payer (ie to the consumer ... And not the blow of the carbon tax at the EMISSION which seems to be there only to pounce real statistics on the wrong side of logic ... and hide the crap with the cat)

No, I am convinced that "We are responsible" largely carbon emissions (pollution inherent to the transport included) of China since imposed by our economic "model" consummerist! Which requires low production costs based on the "oil economy".

Instead of favoring local productions from renewable resources.

By looking well, in fact, we must find very "wasteful" small countries.

In this case, I compared the US with China ...

CO2 emissions up

July 18, 2012

CO2 emissions increased by 3% in 2011 worldwide, reaching the record level of 34 billion tonnes. But they are down in the countries of the Organization for Economic Co-operation and Development (OECD): in Europe, emissions have decreased by 3% and in the United States and Japan 2% by 2011, according to a study published on July 18 by the Dutch Environmental Assessment Agency (PBL).

The inhabitants of the United States remain among the biggest polluters of the planet, according to the report which specifies that an American issued an average 17,3 tons in 2011. The average carbon dioxide emission (CO2) per capita was, in 2011, similar in China and in Europe: in China, it increased by 9% to reach 7,2 tonnes of CO2 in 2011, a figure similar to the emissions per capita in Europe, 7,5 tons in 2011.

The general decline is mainly due to "weak economic conditions in many countries, a mild winter in several countries and high oil prices," according to the report. At the same time, China's CO2 emissions have increased rapidly, "due to the pace of economic growth and, above all, the high level of industrial activity." And this increase offset the effects of emission reductions in OECD countries.

It must also be remembered that many of the products consumed in Europe come from China, so that part of the tons per capita in China is actually to supply goods to people in Europe.

Another record for greenhouse gases

At the level of atmospheric concentrations of greenhouse gases years follow and are similar. The annual bulletin of the World Meteorological Organization (WMO) (1), published Tuesday November 20, indicates that the year 2011 marks a new record of concentration of greenhouse gases.
According to the WMO, the concentration of carbon dioxide (CO2) is 390,9 ppm (2), an increase of 0,51% over 2010. Similarly, for methane (CH4), the concentration is now 1813 ppb (3), an increase of 0,28% over 2010. As for nitrous oxide (N2O), its value measured in 2011 is 324,2 ppb, an increase of 0,31%.

These figures represent an absolute record since the beginning of measurements in 1750. It should be noted that the upward trend is not weakening and that the increase measured in 2011 is in the annual average of those recorded during the last decade. Despite international summits and declarations of good intentions by governments, global warming still seems to be ahead of him.

1- Established in Geneva, the World Meteorological Organization, which has 187 members, is the authorized scientific spokesperson of the United Nations system for all matters relating to the atmosphere and climate of our planet. The WMO coordinates the measurement of greenhouse gas concentrations via a network of observatories spread over more than 65 countries 2- ppm: initials of “parts per million”, ie the number of molecules of greenhouse gases for a million air molecules. 3- ppb: initials of “parts per billion”, ie the number of greenhouse gas molecules for one billion air molecules.

and the rate of increase for methane (middle curve) resumed after a 'break' in the 2005 - 2006 years.

In short: 400 ppm CO2 in the atmosphere planned for May!

By Delphine Bossy, Futura-Sciences

The atmospheric concentration of carbon dioxide is expected to reach 400 ppm in May 2013! As an indication, before the industrial era, it had not exceeded the threshold of 300 ppm on 800.000 years ...

The alert is launched: in May, the concentration of CO2 could well reach the symbolic value of 400 ppm in much of the northern hemisphere. The information comes from concentration surveys conducted at the Mauna Loa Observatory. The latter provides the longest series of continuous measurements of the concentration of CO2 in the atmosphere. The first measurement, performed by Charles David Keeling in March 1958, showed a concentration of 316 ppm. On the 800.000 last years, outside the industrial era, the concentration of CO2 never exceeded 300 ppm.

If these measurements only account for the evolution of the concentration over the last half-century, it is estimated that before the industrial revolution, the concentration of carbon dioxide did not exceed 280 ppm. According to Ralph Keeling, who took over his father's torch, if we continue at this rate, we should reach 450 ppm within a few decades. Scientists believe that the last high level of CO2 in the atmosphere dates back to the Pliocene, more than three million years ago.

If the forecasts are for May, it's because the Keeling curve is going up and down. The concentration of carbon dioxide is minimal in winter, and peaks usually occur in May. If the threshold of 400 ppm is symbolic, it serves as an alarm signal to remind that it is necessary to reduce greenhouse gas emissions now if we want to avoid the critical increase of 2 ° C for 2100.

indeed, Lessdewatt

The World Energy Outlook had formulated a scenario at 450 ppm as a reasonable limit not to exceed ... On the subject: The Sycamoree Announcement of 13 / 11 / 2009... is still relevant.

We risk crossing briskly this threshold, and plunge the whole planet into the climate unknown ...

The rate of CO2 in the air at the highest since more than 2,5 million years

The World | 06.05.2013
By Stéphane Foucart

A symbolic course is about to be crossed. For the first time since man appeared on Earth. And even for more than 2,5 million years ... The threshold of 400 parts per million (ppm) of carbon dioxide (CO2) atmospheric is expected to be reached in May, at the historical measurement point of the Mauna Loa station (Hawaii) ), where the first measurements of the modern era were conducted, from 1958, by the American Charles David Keeling.

The concentration of CO2 in the southern hemisphere, lower than that of the northern hemisphere, will reach the same level in several years.

At Mauna Loa, the concentration of CO2 was Friday, 3 May, at 399,29 ppm. The previous day, the World Meteorological Organization (WMO) released its climate report for 2012, noting the abundance and intensity of extreme events: droughts, floods, tropical cyclones, and so on.

It's still sad, these people who paper paste information without checking if they are correct, there is not even a personal comment.
