Remember the idea of dumping tons of iron filings in the oceans to encourage phytoplankton blooms? See 'iron filings to remove CO2'.
Well, now an Australian company is planning a similar exercise, as reported in the Telegraph today, using hundreds of tons of Urea, a substance found in some quantity in urine. Urea contains a high proportion of Nitrogen, an element critical to the development of phytoplankton.
The thing is, none of these geo-engineering solutions to climate change is proven, and nobody knows just what problems, or even dangers, might result.
Perhaps it will work, or perhaps it literally will be nothing more than a p*ss in the ocean!

I believe in freedom of speech. But I also don't like bullies on blogs, even verbal ones, as they can drive away those with something valid to say... or offer.
Subjective is fine, but well argued and substantiated is even better. Calm and polite tops. Anything that crosses my personal line will not go up. There may be reasons given, but not guaranteed.
I'm not too keen on 'Anon' as a handle (and the content usually explains why), so if that's what you opt for it may not make it. Sorry.
