the change over the last two generations is little more than a statistical anomaly.
This is provably incorrect.
It has been calculated that there is a >99.999% probability that the global temperature rise "is directly attributable to the accumulation of global greenhouse gases in the atmosphere".

Atmospheric CO
2 has stayed within 2 standard deviations of the mean for the last 800,000 years at least. In the last 100 years, we have catapulted the levels up to over 5 standard deviations away from the mean. That means there is a less than 0.0000001% chance that this is a "statistical anomaly".
history has shown us that both humans and the world will survive.
The human race will survive, sure. But when sea levels rise, the land becomes too barren to farm and there is global famine and drought, billions will die.
