The levels of greenhouse gases in the atmosphere hit a new high in 2011.

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.

    It’s laughable that the World Bank is predicting a 4 degree C rise by the end of the century. We haven’t seen anything near that in the past 200 years. Shrill, very shrill language.

      And they are not alone. Here is a report from PricewaterhouseCoopers titled “Too Late for 2 Degrees?” Some points that got my attention:
      1. In order to hit that target of only a 2 degree increase, carbon intensity must be reduced by 5.1% each year til the year 2050.
      2. The world has not hit that rate of decarbonization in the last 50 years, and now (according to PWC) we will have to do it for 39 straight years.
      3. Even if we double our current rate of decarbonization we hit a 6 degree temperature increase.

      Now, I know PWC is a tax, auditing, and consulting firm. But they have been releasing reports on this topic for a number of years, and this is the first one I have seen that pessimistic. Since they represent a large number of the world’s Fortune 500 firms, their interest is in business sustainability.
      And, since I am an alumni of Coopers and Lybrand, I can tell you they avoid shrill like the plague. Shrill, in tax, auditing, and consulting is a loser. If they are advising their clients that this is something to be concerned about, they certainly do not want to be on the wrong end of their forecast. It would be bad for business for one of the world’s largest TAC firms.

  • I think the Mann-like CO2 emissions about climate change, now blanketing the earth, are a prime cause.
