re: #438 LudwigVanQuixote

OK so the effects of DDT being horrible are so documented that I am shocked that anyone could possibly take up this line of reasoning. As to the ozone hole, bringing questions about that being a bad thing or caused by CFCs is also shocking. The Nobel prize in chemistry was handed out to the researchers that nailed that mechanism.

So you claim to love nature. OK

You were wrong about DDT.

You were wrong about CFCs and ozone. Your wait and see idea would have only made things much worse - and the science was well settled about that in the eighties.

You are currently wrong about AGW.

Dude you are 0-3 when it comes to doubting environmental science.

I did not make a claim about CFCs and ozone other than that there are other positions. I do not have a position of CFCs and ozone. Reread what I wrote.

As for DDT, do you think the WHO was wrong to start allowing it again? If not, then we agree on DDT. I clearly did NOT say it is harmless. I will say that its overuse was tragic too. Correct use is important. It is persistent (an advantage if used properly).

As for AGW, I take a moderate position. I still think we are not nearing a tipping point and, given China’s energy plans, we are going to find out. How long do I need to wait to find out if I’m wrong on that one? Some people were widely quoted at the beginning of Obama’s term as saying we only have 4 years until it’s too late on AGW. That was a political, not scientific, statement so I’m expecting you to be more measured. But seriously, how long?
