Extreme Cherry Ice

Over at WUWT someone posted a comment on Bob Tisdale’s post (see my post about that) drawing attention to my removal of the influences of el Niño, volcanic aerosols, and solar fluctuations from the temperature record. This didn’t sit well with some of their readers, particularly someone using the moniker “Javier,” who had this to say:

Global Temperature Update

NASA has just released their latest global temperature update. It’s still hot (the latest value is shown in red):

By Request: Validation

Per request, I’ve tested the model of global temperature with el Niño, volcanic aerosols, and solar variations. It was suggested using a 15-year time span as a “hold-out” period for validation, but I decided to use longer hold-out period. Hence the model was fit with data from 1951 through 1989, and the period from 1990 to the present to investigate whether or not the model could match data with which it was not trained. I also decided to do this test with the NASA GISS data set.

By Request: Adjusted Satellite (and Surface) Data

By request, I’ve computed the estimated influence of el Niño, volcanic aerosols, and solar variations on both surface temperature data and satellite data.

NPR Science Friday: the Madhouse Effect

Climate scientist Mike Mann will be a guest on NPR Science Friday (at about 2:40 pm today) to discuss, among other things, how crazy climate denial can get. You can find it online here.

Divergence between Bob Tisdale and Proper Analysis

Bob Tisdale has a new post at WUWT about a supposed “divergence” between temperature at Earth’s surface and in the lower troposphere.

Bait and Switch

A new post at WUWT claims to “debunk” claims that “human caused warming doubled western U.S. area burned since 1984.” It was in response to a story in the LA Times of new research in PNAS (Publications of the National Academy of Science).
