You know, if global warming is caused by man, then we have to try and repair the damage. I'm sure no one disagrees with that, but what about if it's not caused by man? Should we just go ahead and let it happen or just accept that it's not our fault and ignore it. If so, why don't we just ignore it anyway?

We adapt. The reasons why we can't just ignore global warming is because it effects every aspect of our life. If the climate changes, most farmers will need to start planting new crops, ecosystems will change and maybe fail, weather patterns will change, etc.

So even if it's just a natural course of events we should try to stop it?

Yes Ali, we should try to change the natural course of the planet.

We can't stop it. I am saying that climate change is unpreferable so we should try to limit what we are doing. If we do have an impact on the environment, we should try to limit it but that is all we can do. Climate change is happening and we need to adapt. It is starting to happen and I do know people in that business, they will have great job security soon.

Climate change is always happening...and human beings survived it before without all the technology we have now.

I am building an underground bunker, anyone want to join me?

Will there be sugary stuff in it? lol

Yes, but our global economy wasn't as dependent on the climate as it is now. One major drought can effect billions.

or flood, or icestorm, or heatwave...

As you said, humans adapt. If they don't they die.

I'd like a ticket merc - please

Bolding mine.
Doesn't mean it was pleasant. Also doesn't mean we can survive the next one. We know more, but we also put a lot more stress on the planet these days.

As with every global change there will be bad things AND good things that come of it. We never hear about the good things.

Bad: sections of the planet become unlivable.
Good: other sections of the planet become livable!

Bad: sea level rise.
Good: Manhattan streets finally clean!

Bad: no ice platforms for polar bears to fish from.
Good: overfishing is a problem anyway!

Bad: change in ocean currents put Britain into permafrost.
Good: George Galloway finally shuts up!

Bad: Alaskan caribou lose homeland.
Good: We can finally drill for oil there!

Hahahahaha

You know, regardless of whether or not human beings are playing a part in global warming (which I believe we definitely are), there are other reasons to try to curtail our output of co2, like health reasons. My god, it used to sicken me driving on the freeway in LA. The smell of all that burning gasoline made me literally ill. And I can smell it here in Savannah too. So it isn't just big cities where there is this impact.

In addition, what about that huge spill at the coal plant last month? Or the oil spills in the oceans? Or the strip mining, which releases all kinds of heavy metals into the environment?

The truth is, as a species, we are not very efficient at getting our needs met in a way that isn't harmful. Don't you all want clean air to breathe? And fresh water to drink, and nutritious food to eat? We NEED to reduce our impact on the environment.
