There is a growing strand of opinion (excuse the pun) that suggest
that there are some considerable benefits to be seen from more CO2
in the atmosphere and this article adds to this.
Good point and well done.

It's been known for years that plant growth is encouraged by higher
levels of CO2. This, and the warmer conditions that additional CO2
produces may well ensure crop yields are higher.

However the downside of all this is that the climatic bands will all
shift northwards, leading to enormous disruption to farming, not to
mention the stress on the ecosystem.

All that luverly rich tundra

Tundra is froxen swamp, underlain by ice that built up over the millenia,
and covered by a think layer of moss and lichen. Nothing worth farming even
if the melting doesn't put it under water.
