Angus, local climates change. They can vary at the limits of the norm. Whether it's warming or cooling, man is powerless to change that. Rather than waste trillions attempting to prevent something out of our control, the resources need to be spent adapting to the changes. Climate is never truly static.
Adapt or die... A basic rule of nature.

Round we go.
We know that mankind can change climate. In a flash, by going into a total nuke war.
However it's must tougher to say what our daily activities do. But here goes:
We know we can change and have changed the surface and vegetation of our planet by quite some measure. And we know as well, that capturing warmth is related to the surface.
We also know that we can and have changed the composition of the atmosphere by some bit, and we steadily carry on. And we do know, that the composition of the gases in our atmosphere does affect the temperature.
All we have done has a push towards causing warming. It is but a question of by how much and not if.
Sadly, this has gone into the trenches of propoganda, fake, paranoia, denialism, populism and money grabbing.
In the meantime, guys like myself, who is very dependant on both weather and climate, try to conclude something from our own heads. And the "local" climate I am looking into is on a very BIG "local" area.
BTW, GW would not leat to every zone on the earth warming.
So, I do hope that the measurements carry on, and some real truth will see the daylight.
Meanwhile, I look forward to growing rapeseed for oil, and Exxon gets the drill-grease ready for new ventures in new ice-free zones.
