Climate Regulation - April 2007

Newsletter Issue 2, March 2007


A stable global climate has been a critical factor in human evolution. Reliable and regular weather patterns are the keystone of successful agricultural production and the civilizations it supports. Complex natural systems have maintained climatic equilibrium by cycling carbon released by fires and volcanoes into the atmosphere back into sediments buried under the surface of the earth, via plankton, trees and plants. It's geo-sequestering of carbon done the old fashioned and time-tested way.

Unfortunately, the large amounts of green house gasses (carbon dioxide, methane, etc) emitted during the Industrial era has been combined with an assault on the tools that nature uses to regulate the climate: forests, soil and the ocean. So we find ourselves in a downward spiral, driven by carbon emissions, and with diminishing resistance from the weakened natural systems that provide our only defense against a hot and unpredictable global climate.

The actions below relate directly to two ways we can assist nature to regulate our climate and halt global warming. Firstly, we must rapidly reduce our carbon emissions. Secondly, we must assist those natural systems that store carbon.

Actions to rapidly reduce our carbon emissions
Buy renewable electricity
Ride a bike
Adopt a vegetarian diet
Embrace energy efficiency
Public transport
Buy local & seasonal food
Car pool
Eat less meat

Actions to assist natural systems that store carbon
Join a revegetation group
Reduce & offset car emissions
Adopt a vegetarian diet
Buy paper & wood responsibly
Eat Organic Produce
Help Protect our Waterways

Valuing climate regulationClimate
The value of a natural service can be estimated by calculating what it would cost for use to manufacture this resource artificially.

To calculate the cost for us to rapidly stop carbon emissions and implement an efficient technical method to withdraw excess green house gasses from the atmosphere is beyond my knowledge. However, the Stern Report identified a likely cost to most economies of between 1 – 20 % of GDP. Hence, we could value the natural service of Climate Regulation at between A$6.66 to $133 billion per annum.
