I'm way out there. I believe when weather is warm human activity increases and creates co2.
fraudcurrents... you can't even find a list of nutter scientists who state man made co2 is causing warming. When asked to provide lists you provide political statements from groups... but no scientists actually saying it.
Even the main nutter Hansen says that co2 is said to be the cause... he does not say it is... when I read his statements.
Here you go. Take your meds and look over all of the info here. There is one scientist that clearly states it.
