Petition Tag - gas emissions
March 22, 2006
There is an urgent need to tackle Global Warming. The concentration of greenhouse gases in the air is increasing rapidly. The main greenhouse gas, carbon dioxide has increased it's concentration by 35% since the industrial revolution and its concentration is rising at over half a per cent per year. As a result the earth has warmed by half a degree Celsius in the last thirty years.
The Arctic is warming much faster than the rest of the world.
The warming is caused by the emissions by human society of greenhouse gases, primarily carbon dioxide, which absorb infra red light in the lower atmosphere.
Continuing emissions of these gases are causing a grave danger that the Arctic will warm sufficiently to cause the sea ice to melt completely in late summer leading to a runaway greenhouse event.
The best way of avoiding this future is to make huge reductions in greenhouse gas emissions immediately. There should be an immediate global reduction in the emissions of greenhouse gases, particularly carbon dioxide, by 35%, but assuming the world will not agree to this Britain should take the lead and make these reductions unilaterally by taxing carbon emissions. Hopefully the rest of the world, especially nations with high per capita emissions of greenhouse gases will follow our example.
Even deeper cuts will have to follow so that global greenhouse gas emissions are reduced over the next few years by 75%.
Australia's greenhouse gas emissions have increased 16.9% in the past decade. The year 2000 saw the highest annual increase in emissions since 1990. It now seems nearly impossible for Australia to reach its Kyoto targets.
Already there is evidence of widespread coral bleaching and unless there is urgent action, we face losing large areas of the Great Barrier Reef within the next 40 years.
