WMO figures show the levels of carbon dioxide in the atmosphere has reached a new high last year to 390.9 parts per million

The amount of carbon dioxide that trap heat in the atmosphere has reached a record high of 390.9 parts per million (ppm) in 2011, according to a report released Tuesday by the World Health Organization UN Meteorology (WMO). This is an increase of 40 percent over 1750 levels, before man began burning fossil fuels seriously.

Although CO2 is still the most greenhouse gas emissions important long-term levels of other heat-trapping gases have also reached record levels, according to the report. Methane, for example hit 1813 parts per billion (ppb) in 2011, and nitrous oxide have increased by 324.2 ppb. In total, the amount of heat that prevents leakage excess space was 30 percent higher in 2011 than it was as recently as 1990.

These are alarming, not because they surprise us, but rather because it is not. Scientists know the properties of heat-trapping CO2 since the 1800s. They documented the steady rise of CO2 is pumped in large part on exhaust pipes and chimneys since 1950.

However, despite this knowledge, the world has failed to act to reduce emissions. The best I can do in a climate meeting sponsored by the UN in Copenhagen in 2009 according to a non-binding target of limiting greenhouse gas emissions in the world suddenly increase the temperature of no more than 2 ° C (3.6 ° F) above pre-industrial levels in order to limit potential damage. Only a year later, it was clear that they would not approach what is.

Frustrated by the lack of global action, the World Bank published a report saying that Sunday without significant reductions in emissions, average global temperatures could rise by 4 ° C (7.2 ° F) since by 2060. The report highlighted the disastrous consequences for human health and safety -. Even dangerous rise in sea levels, heat waves and other extreme weather events

But potential disruption of persons and property are so huge that the report is that if there is a warning at least another attempt to revive world leaders after failed attempts during and stops.
Call not only by reducing CO2 emissions, but also an aggressive program to reduce other drivers that global warming might be easier to control, which includes not only the greenhouse emissions absorbers short but powerful, such as methane, but also heat, such as carbon black -. essentially soot
