>See: the "hockey stick graph," that deliberately cut out the medieval warming period.

Even if you add the Medieval Warm Period, the data doesn't significantly change.

>The whole thing is an elitist doomsday cult that demands that peasants give up luxuries (like air travel and reliable electricity) best reserved for their betters (who fly to climate conferences in 5-star hotels and live in mansions on the coasts; which according to them should be underwater as of last year).

Politicians being dicks means nothing about climate science. This is a worthless criticism.

When the Earth comes out of an ice age, the warming is not initiated by carbon dioxide but by changes in the Earth's orbit. The warming causes the oceans to release carbon dioxide. The carbon dioxide amplifies the warming and mixes through the atmosphere, spreading warming throughout the planet. So carbon dioxide causes warming and rising temperature causes carbon dioxide levels to rise. Overall, about 90% of the global warming occurs after the carbon dioxide increase.
