The Intergovernment Panel on Climate Change (IPCC) believes that the influence human activity is overwhelming, their evidence is
The increase in global temperatures coincides with the increase in greenhouse gas emissions
If greenhouse gas emissions continue to rise the Arctic ice will melt (which has already begun)
Natural processes could not have produced all the changes taking process
What are the choices?
There are two main ways to deal with global warming - mitigation and adaptation
Policies (such as the Kyoto Protical in 1997) reduce or prevent further global warming are referred to as mitigation stratagies. These attempt to reduce the amount of carbon emissions and finding ways of dealing with excess greenhouse gases
Yet, CO2 has a life of 100 years so policies that deal with the now and needed. The world has to cope with the impacts that are already occuring, these are known as adaptation

Emissions have to be reduce immediately if the world is to avoid irreversible climate change - enviromentalists say that adaptation policies waste time as the world should concentrate on difusing the root problem: emission of greenhouse gases
Adaptation policies are supported by those who believe in the "fossil fuel society", so that "business as usual" continues. Unless this is challeneged, change will never happen
Carbon sinks (anything that absorbs more CO2 than radiates) can easily be achieved with the government planting trees (sidenote: trees give off more CO2 in their first 10 years of life than absorb)
Cutting emissions in the developed economies (transport, off-shore wind farms) is politically acceptable and gains support, so this should be encouraged more
Cutting greenhouse gas emissions in the growing economies, who are the biggest polluters (China and India) as the developed worlds emissions are falling whilst these couontries amount of pollution is increasing

It will take a long time to get all countries to agree to reduce carbon emissions
To purswade countries to agree to lower the amount of emissions, it must get worse before it gets better, we have to learn to cope when it gets worse
Even if we cut down on what we emit today, CO2 has a life of 100 years - we have to cope with these century long problems
Keeping greenhouse gases the same or even below current standards is unrealistic, with the emerging economies ever-growing it is bond to increase
