Asteroids, Polar Bear Cannibalism Lead to Global Warming, or, uh, Something Bad

Why do we spend so much time and effort discussing an event that "may" happen (global warming) and so little time and effort discussing an event that "will" happen (a very large object from outer space) hitting earth? I could be wrong, but is seems to me far more humans will die as a result of a large object from space hitting earth.

I vote that we send ALL the liberal researchers and "global warming" crowd out to stop that large object from outer space. Why with their hot air and blovating , they should be able clear all that stuff from space.

Well, both dangers are real. But the danger from global warming is the one that isn't an "if". It's the one that will for sure happen if we don't change our fossil fuel habits.

We do have some asteroid sky searches going. We know where most of the big asteroids are, and we've plotted their trajectories forward a few centuries. None of the ones we know about are going to hit us any time soon.

As these searches continue, we will find a few more big ones and a bunch of somewhat smaller ones. Finding all the bus-size ones will take a long time and the job may never be completed.

We also have devised ways to deflect an asteroid if one would be on a path that would hit us in 20 years, say. That far in advance, any little bump to the asteroid will cause it to miss. It's like a tipped pass. Just a little deflection suffices.

Send a rocket out and just slam into the asteroid.

If it's an enormous asteroid, we cannot deflect it with 20 years lead time. But with a century or so, there are other tricks. Paint it white, say. The pressure of the sun's light on its surface will be increased because it reflects rather than absorbs, and that will subtly alter its orbit. Over time, that adds up and can cause it to miss. Or build a solar powered mass driver on its surface and let the machine shoot lumps of asteroid off.

Actually, there are plans to deflect such objects!

I would be in favor of firing Liberals from cannons towards the asteroids in hopes of eliminating at least one of the problems.

Silly goose! If we spend enough money and give enough money to endangered nations that will suffer grievously from the global warming we're causing, we can STOP global warming in its tracks.

There's no way we can stop large objects from space hitting earth.

Yeah, and it is easier. We can stop global warming caused by man by doing nothing at all. Or, we can do something. It doesn't matter which, as far as global warming is concerned.

Silly If we give enough money to countries that will suffer we will stop what....If we help the countries that will suffer from climate change we will do just that we will help them. We can do allot of things that will further clean the air and water and reduce our CO2 but we are but one polluter. Not that CO2 is a pollutant but we do surely pollute..How about India and China, nothing to see there huh?? If we fail to learn from history we will be condemned to repeat it.

Its called climate change for a reason...We don't know the facts really, we only know what we can dig up and we can monitor temps from space and learn. Maybe we will be able to change the climate someday but it will do it all by itself.

Two different topics. No one, and I mean no one, knows which climate cycle we are really in - global warming, maybe long term cooling may be in the works. After all, the little Ice Age that ended in the early 1930s had breaks in some places and warmed, while in others it grew much colder. Maybe we are on the verge of abe a change to cooling. Today, the evidence for long term global warming is not THERE!

The most pathetic part of the whole episode was that I knew that I would find it is soon as I saw the headlines and read the stories.

“A meteor streaked across the sky and exploded over central Russia on Friday,” reported Reuters, “sending fireballs crashing to earth which shattered windows and damaged buildings, injuring more than 500 people. People heading to work in Chelyabinsk heard what sounded like an explosion, saw a bright light and then felt a shockwave, according to a Reuters correspondent in the industrial city 950 miles east of Moscow.”
