o really? how/where/when did they verify what happened 100,000 years ago?
unfortunately, science isn't about "safe assumptions", it's about observable facts and reproducible lab results
Hmm, having read that report the last line was interesting, Howard claiming that it was impossible to run the country's power on solar energy! That sounds like bullshit to me, as altho it might be extremely expensive and difficult to set up, surely you could just cover the outback in massive solar panels?
