Oprah does climate change
I missed it, but apparently Oprah has moved into the climate debate.
Check out the hype on Jbruno'z blog:
Is there anything Oprah can't do
Two interesting things about this blog:
1) The hybrid car Toyota Prius: it saves on fuel when driving round the city, but burns it big time on highways. Apparently the corolla (gotta love em) does a lot better on the highway that the Prius (which switches to pure petrol burning at high-revs highway commuting). Apart from this, of course, electric cars need to be plugged in, thus are pulling electricity from some power station which is burning coal, which produces more CO2, and so is not really cutting down on greenhouse emissions.
2) Trees suck more water out of the ground, as well as CO2 out of the air. This is true. Its touted as a problem in this article. But in Australia, in places which have been denuded due to agriculture, the problem is the (saline) water table is too high, effectively salting the Earth. Plant some trees in these regions, the water table drops, and increasing salinity is less of a problem. Its a win-win, really.
In case you don't think salinity's a problem, check out the havoc it wreaks in Australia:
