Should We Be Worried?

Guest Post by Willis Eschenbach I chanced to plot up the lower tropospheric temperatures by broad latitude zones today. This is based on the data from the satellite microwave sounding unit (MSU), as analyzed by the good folks at the University of Alabama at Huntsville. Here are the results, divided into tropical, extratropical, and polar.…

Global Temperature Report: December 2013

2013 was 4th warmest year in the satellite era From University of Alabama, Hunstville. Global climate trend since Nov. 16, 1978: +0.14 C per decade December temperatures (preliminary) Global composite temp.: +0.27 C (about 0.49 degrees Fahrenheit) above 30-year average for December. Northern Hemisphere: +0.27 C (about 0.49 degrees Fahrenheit) above 30-year average for December.…

UAH Global Temperature Report: September 2013 – up

While NASA GISS is offline, there’s no shutdown at UAH. From Dr. Roy Spencer: The Version 5.6 global average lower tropospheric temperature (LT) anomaly for September, 2013 is +0.37 deg. C (click for larger version): The global, hemispheric, and tropical LT anomalies from the 30-year (1981-2010) average for the last 21 months are:

The 200 months of 'the pause'

By Christopher Monckton of Brenchley A commenter on my post mentioning that according to the RSS satellite monthly global mean surface temperature dataset there has been no global warming at all for 200 months complains that I have cherry-picked my dataset. So let’s pick all the cherries. Here are graphs for all five global datasets…

About that missing hot spot in the upper troposphere

Climate Dialogue about the (missing) hot spot by  Marcel Crok Over at the Climate Dialogue website we start with what could become a very interesting discussion about the so-called tropical hot spot. Climate models show amplified warming high in the tropical troposphere due to greenhouse forcing. However data from satellites and weather balloons don’t show much…

Global Temperature Report: May 2013

by Philip Gentry, UAH and Dr. Roy Spencer   Global climate trend since Nov. 16, 1978: +0.14 C per decadeMay temperatures (preliminary) Global composite temp.: +0.07 C (about 0.13 degrees Fahrenheit) above 30-year average for May.

UAH Global temperature up slightly in September

UAH V5.5 Global Temp. Update for Sept. 2012: +0.34 deg. C By Dr. Roy Spencer As discussed in my post from yesterday, the spurious warming in Aqua AMSU channel 5 has resulted in the need for revisions to the UAH global lower tropospheric temperature (LT) product. Rather than issuing an early release of Version 6,…

May UAH Global Temperature – unchanged

UAH Global Temperature Update for May 2012: +0.29°C By Dr. Roy Spencer The global average lower tropospheric temperature anomaly for May 2012 (+0.29 °C) changed little from April (+0.30 °C), with some warming to near-average temperatures in the tropics being balanced by a little cooling in the Southern Hemisphere (click on the image for the…
