Solved: CO2 emissions 93% correlated with temperature and soil moisture, NOT human activity!
Carbon cycle questions

I just finished listening to Murry Salby’s podcast on Climate Change and Carbon. Wow.
The abstract for his talk is here:
PROFESSOR MURRY SALBY
Chair of Climate, Macquarie University
Atmospheric Science, Climate Change and Carbon – Some Facts
Carbon dioxide is emitted by human activities as well as a host of natural processes.
...
Andrew Bolt has some reactions in the Herald Sun:
Salby’s argument is that the usual evidence given for the rise in CO2 being man-made is mistaken. It’s usually taken to be the fact that as carbon dioxide concentrations in the atmosphere increase, the 1 per cent of CO2 that’s the heavier carbon isotope ratio c13 declines in proportion. Plants, which produced our coal and oil, prefer the lighter c12 isotope. Hence, it must be our gasses that caused this relative decline.
But that conclusion holds true only if there are no other sources of c12 increases which are not human caused. Salby says there are – the huge increases in carbon dioxide concentrations caused by such things as spells
of warming and El Ninos, which cause concentration levels to increase independently of human emissions. He suggests that its warmth which tends to produce more CO2, rather than vice versa – which, incidentally is the story
of the past recoveries from ice ages.

New research: warmth produces these carbon dioxide concentrations
Professor Murry Salby, chair of climate at Macquarie University, has inleashed on global warming alarmism in a lecture this week to the Sydney Institute.
Salby has worked at leading research institutions, including the US National Center for Atmospheric Research, Princeton University, and the University of Colorado, and is the author of Fundamentals of Atmospheric Physics, and
Physics of the Atmosphere and Climate, due out in 2011.

I’ve summarised this from just a rushed hearing of his lecture, not having access to his notes or the charts he produced on the evening. His findings, he says, have been peer reviewed and accepted for publication, so more will
follow.
Some other highlights of his talk:
He said he had an “involuntary gag reflex” whenever someone said the “science was settled”.
“Anyone who thinks the science of this complex thing is settled is in Fantasia.” The climate models used by global warmists suggest we should have twice the warming we’ve actually seen recently.

Here is an idea, why don’t we eliminate this moron’s carbon foot print from the face of the earth. This idiot is the type of individual who would turn off the heat and set fire to the classroom so as to eliminate the use of those mean, awful energy companies raping the earth.
