Debono, if you are not convinced now then you never will be. There is a campaign of doubt being waged by, in some cases, the same organisations that took on the science that tobacco smoking was bad for your health. This campaign was originally very successful. Many of these same shadowy think tank organisations have been funded by organisations like Exxon in order to give the impression there is doubt about the science and thereby allow them to continue making huge profits with impunity. They sell doubt and you have been sold!

There is a lot of scientific evidence and analysis that says we need to stabilise the amount of CO2 (and other GHG's) in the atmosphere in order to keep the global temperature rise below 2 degrees celcius. The only doubt about this is whether the CO2 level needs to be at 450ppm or 550 ppm - some are even suggesting as low as 350ppm which we are well above already! Some of the uncertainty arises with the feedback loops - for example as clathrates in the ocean and permafrosts on land melt, large amounts of methane will be released into the atmosphere. Methane is a much stronger greenhouse gas than CO2 so it will amplify the warming.

I support Cate Blanchett's stance. I am a signed up GetUp member and as far as I am concerned they are doing the right thing.

The constant fear mongering, anti-science tirades and general lack of insight I read here on HC is always very disturbing to me.
