Tropical lizards safe from climate change forced extinction

Some good news from Dartmouth College Climate change may have little impact on tropical lizards Dartmouth study contradicts predictions of widespread extinction A new Dartmouth College study finds human-caused climate change may have little impact on many species of tropical lizards, contradicting a host of recent studies that predict their widespread extinction in a rapidly…

Natural Variability in the Widths of the Tropics

Guest Post by Willis Eschenbach In my previous post, “Does This Analysis Make My Tropics Look Big?“I discussed a paper called “Recent Northern Hemisphere tropical expansion primarily driven by black carbon and tropospheric ozone”, by Robert Allen et al, hereinafter A2012. They use several metrics to measure the width of the tropics—the location of the…

UAH Global temperature, up in April

UAH Global Temperature Update for April 2012: +0.30°C By Dr. Roy Spencer The global average lower tropospheric temperature anomaly increased again in April, 2012, to +0.30°C., with warming in both Northern and Southern Hemispheres, but slightly cool conditions persisting in the tropics (click on the image for the full-size version): The corresponding April anomaly from…

UAH global temperature anomaly – still below the zero line

UAH Global Temperature Update for February 2012: -0.12 deg. C By Dr. Roy Spencer The global average lower tropospheric temperature anomaly cooled a little more in February, 2012, again not unexpected for the current La Nina conditions in the tropical Pacific Ocean (click on the image for the full-size version): The 3rd order polynomial fit…
