In this week’s post at The Daily Blog — Up a blind alley (without a paddle) — I ruminate further on the message to be gleaned from last week’s flooding in Christchurch, and how ignoring the shape of things to come makes for bad government and worse politics:
What happened in Christchurch was not a consequence of climate change (though the heavy rainfall is something expected to increase in a warming world), but an early warning of what will happen to coastal cities as sea level rise takes its toll over coming decades. With CO2 nudging 400 ppm, the planet can expect the sea to eventually stop rising when it is 15-20 metres higher than today. It might take a few hundred years to get there, but if we don’t act to reduce atmospheric carbon it’s not just a distant threat, it’s a long term certainty.
With another storm bearing down on the country from the tropics and severe weather on the cards for much of the country over the weekend, the government may well have to confront another flood emergency. We can only hope they learn something more than how to deploy the prime ministerial mop.
