Re: The bright side...
Correct. Asteroids will put up a bunch of dust into the atmosphere and block out the light. There is tons of evidence for this happening in the past. This is how all of the dinosaurs died.
Global warming is rather complex. It is caused by C02 and methane trapping heat in. As the heat gets trapped in the icecaps melt and the ocean rises. There are many who think the thermohaline belt (ocean conveyer belt) will then fail and cause temperate climate areas like Europe to freeze over. Europe ends up going into an ice age. Since Europe is now covered with ice, Europe turns into a mirror and starts reflecting all of the sunlight back into space.... Then a whole new mess of problems begin. National Geographic did a story on this a few months back, I highly recommend it. It's a great introduction into global warming.

It's official. It's going to miss us. 1/54,000 chance of hitting. It's still going to be very close though.

We are only watching a tiny fraction of the sky. That is the reason I posted the 2x Hiroshima asteroid. We didn't even notice it until it passed. And it flew under our satellites!

If NASA isn't going nuts.... [/ QUOTE ] Do you think this qualifies? http://www.b612foundation.org/ Look at the main page, it says We need to act now... and you can help.. They are pleading to the general public. Check this out: http://www.b612foundation.org/about/welcome.html For this reason the B612 Foundation, recognizing that national governments feel (to the extent that they have considered the matter) that they are not in a position to spend public money on mitigation, are taking the initiative now to begin this process with the use of private funds. We believe that there are adequate numbers of intelligent and concerned people to support the critical initial planning work that needs to be done to eventually reach an operational system to deflect incoming NEAs. Our conviction is that there is nothing more powerful to convince the public that this audacious challenge can be met than to actually do it. It's kind of sad when the best and the brightest of us aren't listened to. Situations like these make me wish I went into B-school.

Re: Asteroid flies under satellites. Big asteroid 1/60 odds to hit 20
Their slogan cracks me up.
B612 "Our goal is to significantly alter the orbit of an asteroid in a controlled manner by 2015" When they accomplish it, I hope they change it to: B612 "Significantly altering the orbit of asteroids in a controlled manner since 2015."

Re: Asteroid flies under satellites. Big asteroid 1/60 odds to hit 2029
Well they know a Tsunami comes every 40 years and kills 50,000 people - look how prepared we were for that........
