Dr Roy Spencer explains about the icy coldness now gripping parts iof Canada and US: "For as long as we have had weather records (extending back into the 1800s), lobes of cold air rotating generally from west to east around the polar vortex sometimes extend down into the U.S. causing wild winter weather and general unpleasantness.....We used to call this process 'weather'. Now it’s called 'climate change'”.


Australian climate analyst, David Archibald, explains in full detail at WentworthReport.com, how the global warming myth was conjured up in 1980, and why, and rebuts the false claims by warmist propagandists. As Archibald says: "There is only one true path. This is dictated by physics, chemistry, and economics." THIS IS A MUST-READ.


Bob Tisdale posts at WattsUpWithThat: "This is a long post: 3500+ words and 22 illustrations. Regardless, heretics of the church of human-induced global warming who frequent this blog should enjoy it. Additionally, I’ve uncovered something about the climate models stored in the CMIP5 archive that I hadn’t heard mentioned or seen presented before. It amazed even me, and I know how poorly these climate models perform. It’s yet another level of inconsistency between models, and it’s something very basic. It should help put to rest the laughable argument that climate models are based on well-documented physical processes."


Emeritus Professor Geoff Duffy writes: "The GHG concentration of the actual atmosphere is 1.028% of the total atmosphere, based on water vapour being 1% (200C, 75% Relative Humidity). The main gases from possible agricultural sources (methane and nitrous oxide) total only 0.02% of all the GHG, or 0.00021% of the total atmosphere......Hence, it can be concluded from all the available evidence that their contribution to any potential change in weather is miniscule".

Extract from a reply by astronaut Harrison Schmitt on climate change: "Right now, in my profession[geology], there is no evidence. There are models. But models of very, very complex natural systems are often wrong. The observations that we make as geologists, and observational climatologists, do not show any evidence that human beings are causing this. Now, there is a whole bunch of unknowns."
