FREAKY FACTS... The heat is on

1) Everything we do now towards reducing the greenhouse gases heating up our planet won’t be felt for another 30 years. This is called the climate commitment.
2) The world has already been heating up for 30 years, with global temperatures increasing 0.6 degrees Celsius overall. We now face another three decades of fast warming, with temperatures expected to again rise 0.6 degrees.
3) The main greenhouse gases caused by people’s activities are carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), chlorofluorocarbons (CFCs) and ozone. Water vapour is also an important greenhouse gas.
4) About 64% of the warming effect of greenhouse gas increases over the last 200 years is due to carbon dioxide, produced mainly because of human activities through using fossil fuels, deforestation and agriculture.
5) Records show that 11 of the last dozen years were among the 12 warmest on record worldwide – and it’s getting warmer.
