In their earliest reports the IPCC conceded that up to 2C of warming was beneficial. Current realistic estimates are that doubling CO2 will warm by less than that, which has left the IPCC with the problem of how to justify their anti-industry measures. They have responded (just as they morphed ‘Global Warming’ to ‘Climate Change’ when the 1998–2013+ Pause in warming happened) by changing the target to 1.5C, hoping nobody would remember their earlier 2C statement.
I heard a rumour that it is the sun that affects global temperature the most. But what do I know? I am not a government-funded scientist with a mortgage and pension to protect.

Teachers need to encourage children think for themselves. Set a class project:
Here is a ruler, measure global sea level changes to within 0.05″.
Describe how you allow for fluctuations caused by waves, tides, wind and movements of continental plates.
A statement that global sea levels have risen by 0.3″ is impossible to corroborate by any means known to man.
