Here’s an excerpt from a cautiously optimistic article in response to all the end-times weather we are having worldwide.
From climate change writer Paul Gilding’s blog, The Cocaktoo Chronicles :

Paul Krugman wrote in The New York Times recently: “The evidence does, in fact, suggest that what we’re getting now is a first taste of the disruption, economic and political, that we’ll face in a warming world. And given our failure to act on greenhouse gases, there will be much more, and much worse, to come.”

But don’t panic. We will wake up soon. Not because the ecosystem is showing signs of major breakdown. Not because people are drowning. No, we will wake up because something much more important to us is now clearly threatened. When you try to create infinite growth on a finite planet, only two things can change: Either the planet gets bigger, which seems unlikely, or the economy stops growing. It’s the end of economic growth that will really get our attention.

There is surprisingly good news in all of this. We as humans have long been very good in a crisis. We ignore our health issues until the heart attack; our unwise lifestyle choices until the cancer diagnosis. We ignore our badly designed financial system until the economic crisis; or the threat of Hitler until the brink of war. Again and again, we respond to problems late, but dramatically – and, crucially, effectively. Slow, but not stupid.

This is a good attribute, given what’s coming. We’re going to have to transform our economy very rapidly, including our energy, transport and agricultural systems. This transition – to a zero net CO2 economy – will soon be underway and the business and economic opportunities for those who are ready (and risks to those who aren’t) are hard to overstate.
