  1. This is a waste of time

  2. It’s probably been explained somewhere- but why a 30 year average? It seems arbitrary.

    1. Because if you use a shorter time frame you could get a decreasing trend. A 30 year average still gives a slight increase, even thought there has been no warming for close to 20 years.

      1. Lies, Damned Lies, and Statistics.

      2. “even thought there has been no warming for close to 20 years.”

        Not quite correct, but close. This is from a prior AGW article by Bailey.

        “The IPCC report obliquely refers to an August study in the journal Nature Climate Change finding that the observed rate of warming during the last 20 years was half of what a representative sample of the models relied upon by the IPCC projected. Looking at just the last 15 years, the models were four times hotter than the actual trend in the average global temperature.”

        Even the IPCC is will to admit the models don’t match the data. They refuse to admit that the models are wrong or even severely flawed.

        1. Even the IPCC is will to admit the models don’t match the data. They refuse to admit that the models are wrong or even severely flawed.

          Look. The models can’t be wrong. You see, human activity is harming the planet. How could it not? There is no way that burning all these fossil fuels and belching all these gasses into the atmosphere could not be harmful. Thus when something out of the ordinary happens with regards to the climate, it must be caused by humans. How could it not? Prove that it’s not. You can’t.

          The nice thing about using your conclusion as your premise is that you cannot be proved wrong.

          Fallacies for the win!

  3. I’m sorry – could you tell me again what is the ideal temperature, and are we moving away from or closer to it?

    I get so confused by all the BULLSHIT, I forget sometimes.

    1. The ideal temperature is that which makes climate “scientists” get more funding, allows governments to grab more money and freedom from their citizens, and ushers in global government fastest.

  4. It doesn’t say so I’m assuming it’s the 3rd hottest September ever.

  5. Reminds me of the Harvard Law of Biology:

    Under carefully controlled conditions of light, temperature, atmosphere, and nutrients, the organism will do whatever the hell it wants.

    I think there is a climate-based corollary…
