How Bad is the Situation

Summary

We should separate what we know from what we suspect and fear

We know

1. Carbon Dioxide has reached its highest level in the atmosphere for 400,000 years and the damage that will be caused is only beginning to be understood.
2. The oceans are absorbing greenhouse gases and becoming less alkaline. As understanding of the damage to phytoplankton and the whole food chain becomes clearer this is becoming the most serious short term effect.

If we compare what we know of CO2 levels and what we know of CO2 emissions it looks like this.

This is quite enough to make us want to act.

We Fear

The following events may be linked to a greater or lesser extent with the Carbon Dioxide levels, the levels of other greenhouse gases, and other human activities.

1. The polar icecap is shrinking faster than scientists predicted, the Arctic Ocean is warming and Greenland is being affected dramatically.
2. Gulf Stream is slowing and may have stopped for 10 days in 2004
3. Loss of ocean species diversity may cause the collapse of the biggest carbon cycle.
4. Forests are becoming less effective in absorbing CO2 and may decline rapidly due to increased forest fire risk. Canadian Forests Now Generate CO2 2009
5. The first hurricane ever reported has been experienced in the South Atlantic
6. Antarctic problems due to warmer water streams undermining and causing loss of ice shelves. The long term effects are difficult to estimate.
7. Past the tipping point? A ten year window closing?
8. Drought threatens to make poor nations suffer and become more militant. Economic refugees will increase 11/03/08
9. Warming will continue long after humans stop burning fossil fuels.
10. Other significant risks have been identified by the insurance industry.
11. No satisfactory global solution has been proposed.

Our task is to find out as quickly as we can what damage we are causing and how we can put it right. Please help us.
