What indeed? Writing in The Australian, earth sciences prof Ian Plimar says of global warming, "Bring it on!" Highlights:
- For about 80 per cent of the time since its formation, Earth has been a warm, wet, greenhouse planet with no icecaps. When Earth had icecaps, the climate was far more variable, disease depopulated human settlements and extinction rates of other complex organisms were higher. Thriving of life and economic strength occurs during warm times.
- Could Greenpeace please explain why there was a pre-Industrial Revolution global warming from AD900 to 1300? Why was the sea level higher 6000 years ago than it is at present? Which part of the 120m sea-level rise over the past 15,000 years is human-induced?
- During the past 30 years, the US economy grew by 50 per cent, car numbers grew by 143 per cent, energy consumption grew by 45 per cent and air pollutants declined by 29 per cent, toxic emissions by 48.5 per cent, sulphur dioxide levels by 65.3 per cent and airborne lead by 97.3 per cent. Most European signatories to the Kyoto Protocol had greenhouse gas emissions increase since 2001, whereas in the US emissions fell by nearly 1per cent.
