It is 40 years since I wrote my first essay on climate change.

It is now more than 40 years since I wrote my first school assignment on climate change and related environmental issues.
Nothing has changed, except for atmospheric CO2 which keeps rising.
The elephant in the room is still being ignored by people who claim to be climate change believers. (no, its not coal or oil)
Diabetics are no different.
They too stubbornly refuse to do the maths.

Doctors and climate skeptics alike play the not-enough-evidence card without actually thinking. If a randomized trial is the only thing that will make doctors change their mind, then it is not surprising that their patients are not doing so well.
