Global warming 1/4 of what we expected: UN

The New York Post reports:

The world has warmed 0.05 degrees Celsius (0.09 degrees Fahrenheit) per decade over the past 15 years, a fraction of the 0.2ºC (0.36ºF) per decade rate confidently predicted by the U.N. six years ago, according to a leaked copy of the foremost climate report in the world.

That report, which is updated every six years by the U.N.’s Intergovernmental Panel on Climate Change (IPCC), is called the Assessment Report, and the fifth version (AR5) will be released Sept. 27. FoxNews.com has obtained a leaked copy of the first part of AR5 — and data in it appears to acknowledge that the world’s temperatures haven’t skyrocketed as many had feared.

“The rate of warming over the past 15 years (0.05°C per decade) is smaller than the trend since 1951 (0.12°C per decade),” the draft report states.

  1. That means the “DENIERS” have been correct during the “OMG WE’RE GONNA DIE” global warming era.

  2. The average global temperature is pretty much a mythical number. It is certainly pretty noisy and should have a pretty significant standard deviation. They then generate something called an “anomally” by using these noisy numbers and generate “data” to 2-3 decimal places without looking at standard deviations. From this they get trends? So, how is 0.05°C/decade statistically different from 0? For that matter, how is 0.12°C/decade stastically different from 0? Could someone point me to a description of how this is done? It appears to me that they are implying measurement precision they just don’t have.

  3. 1. Warming in the last decade is 25% of what was “confidently” predicted.
    2. CO2 has increased during that period.
    3. CO2 has a negligible effect on warming, one that is overwhelmed by other forcings.
    What part of that is wrong? And if it’s right, what part of the AGW agenda is right?
