Know there is a thread on this (sort of) but read this and was interested in what the 'true facts' are as far as we can tell?
Here's the deal. Global Warming Alarmism and keeping the lie alive is now a massive industry. If the IPCC gets its way, it will become the single biggest industry on the planet consuming significant financial resource and killing many other industries. Globally there are already hundreds of thousands of jobs at stake entirely dependent on this lie. The scientists, IPCC, lobbyists, green energy, Govt agencies were the first to feast in this trough. Now with emissions trading schemes, etc. on the horizon the money involved will rapidly escalate from the tens of billions to the tens of trillions of dollars. With those numbers coming, we now see the greediest pigs of all getting involved - the bankers and financiers.
How did we get to this? Well the average person is essentually stupid and has virtually no understanding of science and physics. If a message is repeated enough by people they trust they will eventually believe it is true despite all the evidence, data and facts that show otherwise. That's why we still have religions and belief in god and gods, and accepted that WMDs existed without any proof at all.
It is simple IQ test.
Belief in Man-made Global Warming = total idiot
