Why is good weather not blamed on Global Warming?

Parts of south-east England currently have a climate similar to the Champagne region in the 1970s (when some of the finest vintages were produced) and millions are being invested in vineyards. That is a benign or even positive effect of global warming. But I'm not sure that mitigates the unbearably hot summers in parts of the mediteranean or destruction of property by wildfire.

Man-made climate change is responsible for mellowing of some harsh climates such as in the Sahara Desert. You don’t hear about that as much (especially if Faux News is your primary source) for the obvious reason that that’s not a problem. Climate change is causing weather that is bad for humans in many more places throughout the world, and that is a very significant problem for humanity.

However, the climate of the Sahara is not getting better quickly enough to be hospitable to human life anytime soon.

Because blaming only the bad weather on GW is the party line.
