TDB today: up a blind alley (without a paddle)

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.

Lost in the flood

This morning’s NASA Earth Observatory image of the day shows the impact of last week’s heavy rain in Christchurch and Banks Peninsula on the sea around. The light blue colours show sediment washed off the land. If you visit the EO page, they provide a helpful reference image: the region snapped from space in late February, when there’s no sign of any sediment at all.

Sign up: Wise Response group petitions parliament to take climate, sustainability seriously

The Wise Response group, set up a year ago to build public and political awareness of the need for a serious review of New Zealand’s future policy directions on climate change, economics and sustainability, has launched a petition to persuade parliament that a “national risk assessment” is urgently required. From the Avaaz petition page:

This petition therefore calls on Parliament as a whole to see funds allocated for an assessment of NZ’s critical risks in 5 key areas:

  1. Economic / Financial Security: the risk of a sudden, deepening, or prolonged financial crisis.
  2. Energy and Climate Security: the risk of continuing our heavy dependence on fossil fuels.
  3. Business Continuity: the risk exposure of all New Zealand business, including farming, to a lower carbon economy.
  4. Ecological / Environmental Security: the risks in failing to genuinely protect both land-based and marine ecosystems and their natural processes.
  5. Genuine Well-Being: the risk of persisting with a subsidised, debt-based inequitable economy, preoccupied with maximising consumption and GDP.

For more information on the petition — which is to be delivered to parliament in early April — see the Avaaz.org petition page, and for background on Wise Response see their web site, or this post at Southern Energy and Resilience.

I’ll support anything that forces the powers that be to revisit their attitudes to planning for climate change, building a resilient and sustainable economy and increasing the health and well-being of New Zealanders. I’ve signed. I hope you will too.

Living in a warmer world

This year really has started with a bang. An unusual concatenation of weather extremes — Britain’s stormy and wet winter – the wettest since records began, 250 years ago – the warm winter in Russia and Alaska, drought in California and Australian heatwaves — has caused many people to consider the role that climate change might have played in driving those weather events. For once, public debate has moved away from the tired old is it/isn’t it happening frame and into concern about what living in a warming world might actually mean for us all. This makes Jim Salinger’s latest book, Living In A Warmer World – How a changing climate will affect our lives (Bateman NZ, 2013) especially welcome.

Salinger has drawn on all the relationships he has built up over a 40 year career as a climate scientist, including a spell as president of the WMO Commission for Agricultural Meteorology, to bring together some of the world’s leading experts on climate impacts. Each is given a chapter to look at what might be coming down the road, and it makes for essential, if sobering reading.

TDB Today: through the looking glass into the world of climate denial

In my post this week at The Daily Blog — Investigating climate change deniers and their spin against global warming — I take a look at the PR campaign being run against action on climate change and one of their most important tactics, creating a smokescreen to hide the reality of climate change:

The resulting exchanges provide an object lesson in life through the looking-glass, that alternative world where warming isn’t happening, climate scientists are colluding in a giant hoax, and the poor old free market is being threatened by gangs of rampant watermelons — great wagon loads of fruit against freedom, leeks against liberty, and carrots against capitalism.

As seen on blogs everywhere, all the time, produced by the willing foot soldiers of climate denial.
