Apparently, 4 degrees spells climate doom

One has to wonder though, since CO2 residence time has been said to be anywhere from  five year to hundreds, or even thousands of years, with no solid agreement yet, how they can be so sure of themselves? From the … Continue reading

CO2 causes earthquakes, is there anything it can’t do?

From the University of Texas at Austin  and the “if a small earthquake happens in the boonies, does anyone care?” department comes this press release that the anti-frackers will most certainly seize upon. Note the word “probably” in the headline … Continue reading

Claim: simulated satellite data back to 1860 proves global warming caused by humans

This is just nuts, sorry, I just don’t have any other words for it. Computer modeling and simulations are not hard data nor empirical proof, especially when trying to hindcast the upper atmosphere temperature back to 1860, well before radiosonde … Continue reading

Earth’s self regulation of Carbon Dioxide is remarkably stable

From CSIRO: “What we learned is that in spite of droughts, floods, volcano eruptions, El Niño and other events, the Earth system has been remarkably consistent in regulating the inter-annual variations in atmospheric carbon dioxide levels,” Tropical ecosystems regulate variations … Continue reading

Schellnhuber thinks he can forecast El Niño a year in advance

From the Potsdam Institute for Climate Impact Research (PIK) where breakthroughs happen even before they have a proven track record. It appears he was able to predict one event last year in 2012 from the method run in 2011, but … Continue reading

Plants that got buried during the Little Ice Age come to life again

From the University of Alberta, this news release is making the rounds, but what many of the alarmists don’t get (Joe Romm for example) is that these plants had to have a warm environment to grow in first, then they … Continue reading

“Canadian oil sands pollute nearby lakes. Report is blow to Keystone pipeline.” (Or Not)

The only “blow to the Keystone pipeline” is in the exaggerated reporting of the science… The “report” (Kurek et al., 2013) did find slight elevations (relative to 1950) of polycyclic aromatic hydrocarbons (PAH) in five lakes in the vicinity of … Continue reading

Climate negotiations relying on ‘dangerous’ thresholds to avoid catastrophe will not succeed

From the University of Gothenburg , some appearance of sanity. The identified critical threshold for dangerous climate change saying that the increase in global temperature should be below 2 degrees Celsius seems not to have helped the climate negotiations so … Continue reading

Fresh water flea panic – so it must be happening in the oceans too

From York University   – quite possibly the most poorly written science by press release I’ve seen this year. The leaps of “may” are profound, and the footbal team analogy is designed to elicit sympathy. I suppose if Daphnia populations were … Continue reading

Texas A&M says freshwater hurricanes grow stronger
