CO2 Rise - Do the "Greens" Really Want To End It
His argument is that it would only be if there was a high climate sensitivity to such changes and that since, as the standstill in warming over the last 18 years shows, that sensitivity must be, at most, fairly small.
Fair enough - I agree.
But I previously showed a graph of plant growth to CO2 levels. This Canadian one:
Which suggests that plant growth, which also means crop growth, has improved by about 50% overall since the Industrial Revolution. Now growth in food production has been well beyond that due to the improvements in technology but that 1/3rd of all world food production is down to CO2 increase certainly looks like a very strong counter argument to all the doomsaying on the subject.
Are the "environmentalists" seriously in favour of that sort of collapse in world food production?
