Comet ISON appears to be toast – goes "poof" in video, then comes back to life

Note: See updates below for the ISON ISOFF ISON nature of this comet that has everybody guessing. Picture at right also updated to reflect the new “zombie” status of this comet. Looks like ISON has disintegrated during its turn around the sun. Given the radiation (estimated temperature 5,000F/2,760C – hot enough to vaporize rock), solar…

New paper: climate models short on 'physics required for realistic simulation of the Earth system'

I’m pleased to have had a chance to to review this new paper just published in the Journal of Climate: An Evaluation of Decadal Probability Forecasts from State-of-the-Art Climate Models Suckling, Emma B., Leonard A. Smith, 2013: An Evaluation of Decadal Probability Forecasts from State-of-the-Art Climate Models*. J. Climate, 26, 9334–9347. doi: http://dx.doi.org/10.1175/JCLI-D-12-00485.1 The lead…

Lakes discovered beneath Greenland ice sheet

From the University of Cambridge The subglacial lakes are the first to be identified in Greenland The study, published in Geophysical Research Letters, discovered two subglacial lakes 800 metres below the Greenland Ice Sheet. The two lakes are each roughly 8-10 km2, and at one point may have been up to three times larger than…

A call to action – give #ClimateThanks

Another Internet campaign that could go horribly wrong… Tom Nelson advises me that the Yale Project on Climate Change Communications decided to prod readers into giving “Climate Thanks” this Thanksgiving on Twitter. A silly idea for sure, but certainly better than advocating eating “tofurkey” to lessen climate change. I’m sure WUWT readers have lots to…

Video: Comments on Human-Induced Global Warming – Episode 1 – The Hiroshima Bomb Metric

With much fanfare from the faithful (a grand total of 15 comments as of this writing), SkepticalScience recently released their 4-Hiroshima-Bombs-per-second widget. Their claimed intent is to “raise the awareness of global warming”. Nonsense. Their intent is to scare people—children and adults—into believing that something must be done about global warming. It’s nothing but propaganda—plain…

CO2 in the air, CO2 in the seawater

Guest Post by Willis Eschenbach [See updated graph] Inspired by some comments on another thread, I decided to see what I could find in the way of actual measurements of the amount of CO2 in the surface layer of the ocean. I found the following data on the Scripps Institute web site. What they did…

Spectacular video: Comet ISON imaged from a Langrange point in space

NASA’s Solar Terrestrial Relations Observatory, or STEREO, is monitoring Comet ISON as it approaches the sun. NASA’s twin Solar Terrestrial Relations Observatory (STEREO) spacecraft are parked in Langrange zones, known as the L4 and L5 Lagrangian points, each centered about 93 million miles away along Earth’s orbit. The latest movie from the STEREO-A spacecraft’s Heliospheric…
