I keep seeing articles about 'rebuilding trust in science'

They all focus on changing how science is carried out, but mistrust in science isn't the result of what scientists do - it has been manufactured by the science denialism industry

Science isn't the problem, the forces of anti-science are

If someone tells you the CO2 is coming out of the sea, they try to fool you. We know exactly where it comes from and where it goes. We emit CO2, about half of that stays in the atmosphere, and a quarter each is taken up by oceans and forests.
Measured facts!
