I do however worry about the accidental introduction of invasive species and diseases, which seems to be accelerating (see: citrus greening disease).
That's funny! I was going to start my post with the exact same sentence!
But for a totally different reason: I'm now convinced that there is no stopping the massive destruction of the natural environemnt. A much MUCH bigger problem than that of the climate alone.
I'm not a "doomer", I'm a "realist". It's clear at this point that the world's ownership class is NOT going to allow any significant mitigation of petroleum use.
The situation will continue unabated until all of the worst predictions, and many more not foreseen, come to bear.
So, I've learned to take this in stride, like with gun ownership: most gun deaths in the US are suicide. As more and more gun owners shoot themselves, this is the only mitigation to this crisis.
This will be the same for industrial distruction of our environment, including the climate. The only way it's going to mitigate is when the natural consequences come to bear and destroy a good part of the world population.
Of course, there's always "citrus greening disease" to worry about 8-)
The excuses people are willing to tell themselves will prevent any meaningful responce to the crisis... Thus, the natural consequences will occur...
"We" - the Western voting public broadly, but also much of East Asia too - are the owning class. If you actually removed everything in our lives that depend on petroleum products, it would be a riot before the end of the month. I don't think people quite realize how much of our lives are propped up by the downstream products of oil. It's not just moving people in cars and most of electricity generation and wrapping our food in plastics; it's most of our food production (from fertilizer to mechanization), most of our biochem stuff (so much starts as natural gas), most of our infrastructure.
Without oil, the West is shivering in the cold, the shelves are empty, there's nothing to do, nowhere to go (or really, way to get there anyway) and practically no healthcare.
You square that circle, you let the rest of us know. But we won't (and should not) accept any future like that.
