But you see, you do not have a valid argument in "consensus." Not after the various cases of fraud that have came up. Not after the hockey stick debacle. Not after the email releases. And not after twenty years of no warming.
The scientific consensus is a perfectly valid argument to regular people who want to know what the science says. Can you mention any respected scientific organizations that reject global warming? If not, why not? Are respected groups like famous journal "Nature" taking part in a massive conspiracy?
What cases of fraud?
The hockey stick has been independently verified plenty of times.
What e-mails? The ones in the fake controversy "Climategate" where the science-opponents had to resort to fake quotes and such to create a fake controversy?
It has been warming in the past 20 years as well, sorry.
