I think there are bigger issues. In 1920 the world population was close to 2 billion, just 100 years later it's close to 8 billion. Scientists have estimated that Earth resources could be enough for 9-10 billion people. We are going to get close to that number in the not too distant future , and then go past it.
interestingly there is a link between the warming of the planet and the greening of the planet and the fact that the greener the planet the more food available as the sugars needed for human life become more abundant.
There is a lot more to it than that of course and not all green plant is good for the environment and human land us and cropping also means more food as well which quickly realise CO2 back into the atmosphere.
A question of balance I suggest but it is generally true that the warmer the planet the better conditions for food production but many would argue if it gets too warm there are other repercussions.
Still a lot to research and understand about the correlation and otherwise regarding food production and its impact on the climate.
my view is there are bigger issues for humanity to address than climate change as an issue on its own and mans impact on the temperature on the planet in order to survive and prosper.
if emissions can be effectively reduced without massive cost to the poor namely through private investment and a relatively seamless transition of work and type of work with less regulation and and less government directive to the citizen then its worth pursuing.
Reducing emissions from man made activity is a worthy endeavour to pursue.
Emission reduction as an end to itself without a proper debate on the impact on the environment , food production , taxes , subsidies , land use , farming , energy generation and work and more importantly on terrestrial beings to name but a few may not prove fruitful when all is said and done.
We must never forget terrestrial life is based on carbon and co2 and we cannot change that.
