Definition A
safe climate is loosely defined as a climate in which major unexpected
changes such as the loss of the Arctic Icecap or the decimation of
forests are unlikely. At present this appears to be a global average
temperature half a degree below the present and ocean acidity somewhat
less than the present level. Safety can best be determined as being similar to past stable periods in the earth's recent history. The consensus of science may modify this up or down as more is known about the resilience of the land and ocean carbon cycle. | Means of Achievement The methods needed to achieve a safe climate must be studied for each country separately by the government of that country. The authors of Climate Code Red claim they must include
- Drastic reductions in carbon emissions to near zero
- Removal of CO2 from the atmosphere
- Some short term global cooling measures
- A national emergency will be required to achieve success
Measures
are likely to absorb a significant proportion of GDP ( say 10%) and
contribute very substantially to reflation after the credit crunch. Some
countries have contributed more to the present pollution and must bear
the major cost of the removal of CO2 from the atmosphere. The country plans combined need to be evalated to see how quickly they are likely to bring about a safe climate. |
