The levels of greenhouse gases in the atmosphere hit a new high in 2011.
The atmospheric concentration of carbon dioxide (CO2) – the single most important greenhouse gas – reached 390.9 parts per million in 2011 and is now 40% above the pre-industrial level of 280 ppm, the WMO reports in its new Greenhouse Gas Bulletin released today. Methane (1,813 parts per billion) and nitrous oxide (324 parts per billion) — both potent greenhouse gases — also reached new highs last year.
Mysteriously, however, there has been no measured rise in the temperature of the climate for the past sixteen years, even though every computer model predicted that this increase in greenhouse gases would force a temperature rise.
The conclusion? I have none, other than to point out once again that climate science remains a difficult and complex area of research, filled with large gaps in knowledge and many questions and uncertainties that remain unanswered.
However, we will never get these questions answered if we make believe they don’t exist. It is essential that the climate science community stop pretending that they know what is going on while simultaneously playing politics with the science. Do the research, ask the right questions, and focus on what we don’t know. And tell the politicians to shut up and keep out, as they are surely the last people to understand the science of climate.
That way, we might finally begin to understand what is happening and can deal with it rationally.
