I really wanted to carry on the discussion about Global Warming that started in the Open Forum, but it kind of gave birth to itself smack in the middle of a discussion on Victoria's boulders.
I think Global Warming is pertinent to the subject of Space Exploration because of remote sensing from Space, and also the possibility that if things really start to heat up, we may be faced with the prospect of finding an alternative habitat. So Richard might just forgive me for starting this topic here rather than allowing it to continue on the Open Forum.
I'm concerned that people think that there is a debate regarding Global Warming when all professional climatologists and oceanographers have no doubt that Global Warming is largely due to Human activity.
I am aware of a lot of the hype that goes on, and I think a lot of it has to do with the fact that it's a complex subject, and the general public are looking for simple answers, preferably an answer that makes them feel comfortable.
There have been a number of excellent talks on Global Warming (Let's call it for what it is) on the ABC here in Australia. Robin Williams' Science Show is known for its objective take on many scientific matters.
Here is a short interview with Ralph F. Keeling of the Scripps Institution of Oceanography University of California, one of the world's foremost authorities on Global Warming.
You can see that his refusal to even debate those who are skeptical can easily be taken the wrong way. Scientists are unfortunately not the best communicators.
The whole system is exceptionally complex, and we are just finding out now what the signs of Global Warming will be. The atmospheric content of CO2 has been steadily rising since the late 18th Century. That has been established through many very accurate techniques which I can discuss in as much detail as you'd like.
