Replying to: steve_ (Jan 06, 2009 10:41 am) A 1C or few C rise in temperature would allow more organisms to thrive in wider parts of the globe. On the other hand the natural planet-killer events will wipe-out most large species either immediately, or make the climate harsh for years and kill the initial survivors that way. I have 0% chance of dying from GW in the next decades; my chances of dying from a planet-killer are similar to buying a lottery ticket each day. I'd prefer any GW-research-$ be used for scanning the skies, and developing technology to prevent impacts. |

Replying to: steve_ (Jan 06, 2009 11:45 am) If an asteroid hits, we won't have to worry about bark beetles, climate change or even another episode of Rosie O'Donnell's variety show.

Replying to: grbeck (Jan 06, 2009 12:40 pm)  You know NASA is going to solve the asteroid issue by putting a few hyperspace shooters in orbit. |

Replying to: steve_ (Jan 06, 2009 10:41 am) You miss the OP's point. To use you example, you're worrying how you car handles while it is going off a cliff. He was saying that there may be dangers to mankind that are magnitudes greater than GW (even if it is real). |

Replying to: steve_ (Jan 06, 2009 11:45 am) Trouble is, there are 10,000 out there.

Replying to: steve_ (Jan 06, 2009 11:45 am) And the millions of non-periodic comets that can come from the Oort cloud outside of the solar system? Or the comets of the Kuiper Belt by Neptune? Some of these comets are in thousand year orbits of the sun, like the Levy Shoemaker comets that hit Jupiter. If a comet comes from the other side of the sun, travelling at a typical 100,000 mph, you have a few days notice. NASA does not have any accounting of these millions of objects, nor really looks for them. And unless Bruce Willis has been training, we have no ready defense. Jupiter was hit just 20 years ago by comets that would have killed almost everything except cockroaches. Do you like playing a lottery. This issue is many times more important than the UN considering whether mankind can make a small change in what is a normally changing climate.

For North America this could take our minds of GW for a while. What does the earthquake swarm mean? It is our opinion, and in agreement with Dr. Robert Smith of the University of Utah, that the current events are more of a major seismic event rather than a major volcanic event. The Alert Status of Yellowstone continues, at this time, to remain at the Green Alert Level. We do not anticipate the Alert Level to be raised at this time. The CONSENSUS is a large part of the USA will be covered by volcanic ash if that volcano erupts. It is several times the size of Mt St Helens. Maybe now is the time for that extra coat of wax on the car. The crater atop Mount St. Helens is about 2 square miles. The Yellowstone "caldera" — a depression in the Earth equivalent to a crater top — is some 1,500 square miles. The 1980 Mount St. Helens eruption blew 1,300 vertical feet off the mountain, sent an eruption column 80,000 feet high in 15 minutes, ejected 1.4 billion cubic yards of ash detectable over 22,000 square miles, and killed 57 people. But the last major eruption at Yellowstone, some 640,000 years ago, ejected 8,000 times the ash and lava of Mount St. Helens. And that wasn't even the largest eruption in Yellowstone's prehistoric past. http://dsc.discovery.com/convergence/supervolcano/under/under.html |
