"What – you mean we aren’t controlling the climate?"Correlation of Net CO2 emissions with climate properties shows that the growth in CO2 may be natural
Story Submitted by WUWT reader Steve Brown
"... The narrative of the catastrophic anthropogenic global warming has been challenged at many levels but this presentation by Professor Murry Salby, Chair of Climate at Macquarie University rips up the very foundations of the story..."
He elegantly shows that there is a solid correlation between natural climate factors (global temperature and soil moisture content) and the net gain (or loss) in global atmospheric content when the latter is averaged over a two year period. The hanging question remains, if natural factors drive more than 90% of the growth in CO2 how significant is the contribution of human generated emissions. The answer is simple… not very.
Murry Salby finds CO2 rise is natural
What the science says...
Salby's carbon cycle confusion
"current CO2 values are 380pmmv"(parts per million by volume)
"Net annual emission has an average increase of about 1.5ppmv per year. We're on the right planet. That's the annual average increase you just saw. But it varies between years, dramatically by over 100%. From nearly zero in some years to 3ppmv in others. Net global emission of CO2 changes independently of of the human contribution"
Q&A time - try not to shoot yourself in the foot!
"I think it's a pitfall that people look at the ice proxy of CO2 and take it literally. It's not atmospheric CO2, and I don't believe it's CO2 that was even in the atmosphere when that piece of snow was layed down"
"CO2 after the turn of the (21st) century continued to increase, in fact if anything slightly faster, but global temperature didn't. If anything it decreased in the first decade of the 21st century. Now I'm confident the IPCC (Intergovernmental Panel on Climate Change) will come up with an explanation, in fact they've come up with several"
