The problem is, its like asking the question should we prepare fpr a devastation meteor impact? many say it will not happen in our lifetime so why worry. But then it could. We just dont know. We havent surveyed every Earth crosser that can threaten us.
Going on past climate records re. climate change may not help. You see, never in the history of the Earth has a life form appeared that is capable of burning most of all the hydrocarbons in the Earth.s crust. Thus, the long term result of this is not known.
My person belief is that climate change on a massive scale is being held back by Earths natural thermostats, the oceans, the fact that warmer temps. mean more evaporation hence more cloud which reflects some heat away. However like any thermostat, it has limits and when it "runs out of adjustment" things may get bad real quick.
Ironically Im a person with least to lose with climate change, as I dont have children who must face the consequences of this climate change.
Anyway climate change may be a moot point if worldwide economies collapse because of the ongoing rise in oil prices. How would Australia cope if petrol was $3/litre, what about $5/litre?
When I go to work (on the bus) I see car after car zipping past with only 1 person in them, and many of them are larger cars as well. Fancy needing a shell of 1 or 2 tonnes of metal to move you around, powered by technology developed 100 years ago. Instead there should be electric vechicles weighing no more than 500 kg powered by the latest lithium chemestries, offering 500km+ ranges, 110 kph speed and thousands of charge/discharge cycles, charged either from solar arrays on our houses or using cheap off peak power overnight. Imagine speding only a few dollars a week in travelling expenses.
They talk of Moores Law in computers wheer one day they will stop getting faster and better because the circuits cannot be made any smaller. Well moors law of transport has stopped already, as our cars arent getting any better. They are instead getting heavier and more powerful, not more efficient.
