David Hall’s letter, (December 12) saying ‘the [climate] science is certainly not settled’, with reference to scientists on YouTube, implies the view that a few recalcitrant non-expert, and often non-scientists, constitutes a strong and accurate source of information.
The tobacco industry sowed doubt in the minds of many eventual cancer victims for decades. Now the $10 trillion (annually) fossil-fuel profiteers are repeating the ruse. Apparently, special annual doubt-marketing expenditures are increased when the IPCC goes public around this time every year.
Despite what doubt-merchants say, it’s a statistical fact that by 2014 97 per cent (+/- 1 per cent) of climate experts agreed the dominant cause is greenhouse gases. The consensus is even stronger now. These thousands of scientists state that all other sources of heat do not explain our massive growing thermal anomaly.
Natural climate variability is far less than human-caused global warming, which is now more than 20 times faster than any natural climate changes.
There is an objective reality out there and it’s beginning to smash civilisation. Vulnerable people continue to fall foul of the distortions and untruths pumped out by the greedy fossil fools. Facebook and YouTube should take responsibility for fact checking based on objective science, not fantasyland.
