Brazil's market stock has a "kill switch" that turns off trading in cases such as these. If the stocks take a nose dive because of a computer glitch or
because of a human typo, the kill switch automatically closes the market for that day.
That would be a great feature to add to our stock markets here in the US.
You do realise the papers talked about in the climategate emails were published and did make it into the IPCC reports, right?
There's still the sticky matter of intent. Those emails make the intent clear. Now, maybe the people in question cooled down after the heat of the moment and didn't carry through on their threats. Or maybe they did, but failed due to obstacles in their path. We don't know from the emails, but it's showing more of that blatant and emotional anti-scientific bias that colored their thinking and probably their research.
The person who's taking you to lunch has no intention of paying.
