Hurricane Sandy was not just a storm. It was a stark illustration of the power that climate change can deliver – today – to our doorsteps.
Ask the homeowners along the New Jersey and New York shores still homeless. Ask the local governments struggling weeks later to turn on power to their cold, darkened towns and cities. Ask the entire north-east coast, reeling from a catastrophe whose cost is estimated at $50bn and rising. (I am not brave enough to ask those who've lost husbands or wives, children or grandparents).
I bring up these facts sadly, as one who has urged us to heed the scientific evidence on climate change for the past 25 years. The science is clear: climate change is here, now.
