The Arctic is warming on average twice as fast as the global average, but in places the warming is double even this rate. Implications are immense as the Arctic is literally the worlds air conditioner, or at least most of the world as most of the world’s land is in the Northern Hemisphere. Thaw out…
First published on Truthout, February 11, 2015. The last time we had this discussion was 2013, remember? Before that it was 2010. Before that it was 2005 and everything started with the Super El Nino in 1998. Statistically, saying that 2014 was the hottest year ever is a very valid thing and if you understand…
Varying reports reveal that “tens of thousands” of individuals died in Europe in the 2003 heat wave with 15,000 in France alone. Reporting today still use the inaccurate estimates from the day. The European Union sponsored a study that laid to rest the speculation but this study’s results are so astonishing the numbers are still…
This work out of the Department of Global Ecology, Carnegie Institution for Science, reduces the lag in warming from CO2 emissions from 30 to 50 years to 10. But their constraints are quite different from what we have come to know as the temperature lag. This experiment looked at 6,000 model runs of a 100…
Earth has warmed about 0.9 degrees C on average and the Arctic on average has warmed two to three times as much as the average. Daily temperature variation and annual temperature variation make a difference. Climate scientists have been warming us for over a generation that climate change would mean greater insect infestations on a…
This installment discusses challenges with our ability to collect valid ocean warming data and how these challenges have systematically underestimated the role that our oceans have played in keeping our atmosphere cooler than the models say it should be. One thing that the climate deniers get right, maybe the only thing, is that we still…
Work from the Climate Change Research Centre, UNSW (The University of New South Wales), Australia Shows what temps would be like without anthropogenic interference—including aerosols in the mid 20th century! These researchers used the latest generation of climate model simulations to investigate the occurrence of hiatus periods in the past and under two future scenarios….
First Published on Truthout, August 27, 2014 (link) The fundamental climate change policy question today is not how much we should reduce carbon dioxide emissions by when, but what will currently proposed carbon dioxide emissions reductions do to our climate in the near-term? In addition, what are the ramifications of short-lived climate pollutants that are…
Why is the warming “pause” happening? Carbon dioxide emissions continue to skyrocket. Is it because of natural cycles or because climate scientists have a conspiracy agenda? Or are they simply wrong? The temperature rise has slowed slightly when looking at the short-term, but only slightly. Deniers however say that since 1998 it hasn’t changed at…
Climate change projected by the IPCC 2013 report under the business as usual scenario (RCP8.5) projects climate change in the next 100 years to be as big as the Paleocene/Eocene Thermal Maximum extinction event 56 million years ago. Changes today however are happening 100 times faster than the PETM. The PETM was likely a methane…
New work out of the University of York in the UK and the University of Ottowa in Canada has pretty much patched another hole in perceived temperature flattening myth. We live and we learn. This story has two parts. One is about the UKs temperature dataset and the other about the main US data set…
A study in Geophysical Research Letters has found moss beneath a recently melted glacier on Baffin Island that dates back 44,000 to 120,000 years using radiocarbon-14 dating. This technique uses the radioactive decay rate of carbon-14, a rare but predictable version of a normal carbon atom, to date things that were once alive. The radioactive…
When will we completely leave our old climate? When will our new climate be 100 percent different than our old? When will the normal temperature in the our new climate be warmer than anything in our old climate? It’s called Climate Departure and it is coming soon to a planet near you. On the path…
Much is being said about the IPCC report telling us that there has been a pause in warming. It says no such thing. Not only does it say no such thing, it says that that Earth systems warming (atmosphere, land and ocean) has continued unabated. August was the fourth warmest August ever recorded globally, September…
In early May, after a late season cold front the temperature was a bit chillier than normal. We set four new record lows. It was the 10th coolest May in the record, yet it was only 0.9 degrees cooler than average. After the record lows we set two new record highs. At the same time,…
From the Catalan Institute of Climate Sciences, one of the largest scientific institutes in southern Europe, the French National Meteorological Service and the Catalan Institution for Research and Advanced Studies (Catalonia is basically one of the 17 states in Spain). The predominant part of the “global warming has stopped myth” is based on the concept…
The details of the temperature record are a lot more extreme than the National Weather Service averages reveal. Their current January average for Camp Mabry is 2.1 degrees above normal, but it’s nearly 5 degrees warmer than the 1980 average. Is this just the normal chaos of weather? The annual average Austin temperature has increased…
After twenty years of the D & D game climate change is much worse than it would have been if we had of started reducing emissions as the Kyoto Protocol, and nearly every single climate scientist on the planet suggested was prudent. First published on the Rag Blog, August 8, 2012. Before I tell you…

The UAH temperature record is touted by the D&D crowd as being proof that global temperature is not rising. This paper corrects some fundamental issues with the UAH dataset. Here’s the latest scientific explanation of global temperature and why there is contention on how much it has warmed. The data below represents the consensus post…
