That’s why in the mid 80’s the idea of limiting carbon emissions was put forth. At the time scientists weren’t sure of the data or the full implications … but the possible consequences were severe. And climate being big, complex and poorly understood it only made sense to slow things down and buy some time and not depend on big interventions.

That’s why I was in support of carbon caps and trades even though I had doubts as to the nature and extent of anthropocentric warming.

But over 20 years have gone by since then, and we’ve exceeded the projections of that time … in short, I think it will be too late for passive approaches. We are going to have to intervene in our climate in an active and big way.

Once you have eaten from the apple you cannot return to the garden. Like it or not we are now the stewards and controllers of our planets climate.
