If we cut CO2 emissions today...or Dunning and Kruger visit WUWT again

Update: See below for ABC news item on the horrid but expected decision of this new government to disband Australia's Climate Commission. (The website is still up here.)



Anthony Watts has a cartoon by Josh as part of an article (archived here) telling his readers about how PM Tony Abbott has shut down the Climate Commission.  The cartoon is this one:

(you wouldn't) Credit: Josh - who suffers a serious case of the Dunning Kruger Effect
Source: Home of the DuKEs - WUWT

The object of the cartoon is Professor Tim Flannery who chaired Australia's Climate Commission.  Tim Flannery is not a meteorologist but he knows more about climate than all the deniers at WUWT and elsewhere put together.

If you read the top and bottom of the quote, you'd see that Josh (and presumably Anthony Watts) don't understand much about CO2 or climate.  As you'll see if you don't already know, Tim Flannery is, of course, correct.

One gets the feeling that Josh and Anthony Watts believe that a mere cut in CO2 would result in a drop in temperature.  That's pretty silly of them.  Any old cut in CO2 won't drop temperature.  As long as more CO2 is being added to the atmosphere than leaves it, then energy in the earth system will increase and temperatures will keep going up.  CO2 is a greenhouse gas and what it does is absorb IR radiation.  The more CO2 there is the less quickly will earth radiate energy to space.  That's why earth is heating up.



What the science says about CO2 and future temperature


I thought it might be worth writing an article about what the science says if the world suddenly stopped emitting any and all CO2 and what would happen if we started to cut emissions.
