Phew, this thread is sure contributing to global warming right now!
Alison, it's probably safer to refer to it as "climate change". I assume that when Palin talks about "global warming" she is referring to the acceleration in the pace of change of various climatic indicators.
I think she is being politically naive at best, and expediently dishonest (her oil interests) at worst. I'll think the best of her and assume it's the former.
Politically naive because right now the huge weight of scientific opinion is leaning towards the theory that man is "causing" climate change. For a major political figure to be blatantly out of line with that is simply foolish. She cannot KNOW whether she is right or not, and she would lose nothing by hedging her bets. It again smacks of a character who has the potential to shoot first and think later (too late maybe).
The fact is though that based upon evidence from, amongst many other sources, polar ice cores, the climate is changing as it has done in cycles over the millenia. This time however there is some evidence, growing stronger, that the rate of change is much faster. Many scientists are pointing to man's activities as the reason for this acceleration.
In my book, whether this is in fact the case, and whether in fact it even matters in the long-term (10,000 years +) or the very long term (millions of years +), is irrelevant to the fact that there are some things that man is doing now which he hasn't done on a such a huge scale ever before. For instance:
Emissions of certain well mediarized gases, rapid deforestation, intensive chemically based agriculture, playing with radioactive materials etc.
Whether or not these sort of activities are causing "harm", they are different. So even though a correlation may not yet be proven, why take risks?
I think I read somewhere that Palin is in fact encouraging some measures to mitigate some of the above problems. Perhaps you know about this?
And as I know you'll challenge me to say what I'm doing personally, I:
Reduce travel to an absolute minimum
Never travel by air even on business (cheap package holidays should be banned imo)
Am saving to buy a hybrid car within 12 months
Have planted 250 trees in the last 2 years
Never use chemicals in the garden
Use only organically derived products in the house that are biodegradable
Eat 80% organic and locally produced foods
Try to eat less meat (reduction of methane from cattle)
Switch off all appliances not in use (no standby)
Use eco washing cylces
Buy "green" electricity
Am installing wood burning stoves
Am converting to a wood pellet boiler and geothermal heat pump heating
Recycle and compost approx 95% of waste produce from the home
Compost all garden waste and grass clippings and reuse
Oppose most onshore windfarms
and lots more to do with insulation, solar recovery and ecological land management.
PS You can call me "darlin'" anyday btw, but could you add the "g", it sounds sooo much more refined - and, oh yes, just blown kisses please, I don't like my lipstick smudged.
