Since pre-industrial times, the atmospheric concentration of greenhouse gases has grown significantly…[CO2]increased 31%, [CH4] increased 150%[NO] increased 16% (Watson et al 2001)
The present level of CO2 concentration (around 375 parts per million) is the highest for 420 000 years, and probably
the highest for the past 20 million years.
Growing waste volumes…Waste composition will keep changing...
