Global warming is a good thing. .....more water and more wind! : )

Don't forget. Also warmer. <img src="http://www.catsailor.com/forums/images/graemlins/grin.gif" alt="" />

But do those "pros" outweigh the long list of "cons"?

1) Increased evaporation
2) Extreme Weather
3) Destabilization of local climates
4) Rise in sea levels, temperatures, acid rain, and decrease/shutdown of thermo-circulation
5) Change in ecology
6) Glacier retreat
7) Methane release from melting permafrost
8) Forest fires
9) Polar Icecap Melt
Those are just environmental issues related to the potential effects of Global warming.

Economic:
1) Decline in agriculture
2) Insurance
3) Flood defense
4) Migration
5) Water scarcity

Health wise we get in to the potential for new strains of disease and more people with such issues as asthma.

I’m currently a student at a university that is very dedicated to sustainable development and environmental issues. I get the opportunity to watch debates about environmental problems including global warming on a regular basis and the issue should of concern to the world. Some believe its just a gimmick and such. But scientists and researchers really to believe its slowly creeping up on us and when it does start to affect us personally at a higher degree it will be to late to take action.

I don’t want to get in to details but those are just my 2 cents.

The thing that bothers me most about the nay sayers is that; even if there is no global warming we still benefit from "green" technology.

The benefits of clean air and water should be self-evident. Saving money at the gas pump or on home heating and cooling should be no brainers.

I don't argue that global warming isn't happening, what I argue is the severity, and the actual cause. Any one who takes up a cause is doing so to make themselves feel better. Global warming is just the latest of trendy, feel good, crusades for people to take up. Save the rain forrest, what ever happened to that?

rise in sea level, glacial retreat, polar ice cap melt all sound like the same thing?
You do realise I was joking???
THe point is this. Permafrost in the Ukrain is melting.
The weather is changing. It does not matter why now. This train is not going to be stopped by an economic attitude that will take too long to help. It is now about what we do to survive. These temperature changes have been tracked in the old ice patterns etc. They do not take thousands of years as was once thought. One hundred years from now, maybe fifty the World will be a very different place. Will our electronics etc survice the crazy weather???? Agriculture etc etc.

20 foot rise. A 2 foot rise would do it. The level is not so much the problem. It is the temperature and where the currents take those tempuatures.

I don't care. I have no children and will have been looking at the lid a long time by then.

Sail now, sail fast.

That would require capitalism out and socialism in. no chance. If the man can make millions out of dirty tech and build a big weather proof home he will.
I am all right Jack.
Do we sailors care about the envioroment because we use it? Maybe more sailing would help. I will go out now and do my bit.

Hers a good doco from Nat Geo the times and dates for viewing are for the Australian and NZ market only.

Very interesting veiwing with some merit and good evidence to support thier claims.

12.00pm The Big Freeze

Earth has plummeted into periods of intense cold, time after time. Some of these drops in global temperature are caused by volcanic eruptions. Despite only lasting a few years, they have the power to cause huge social and political upheaval across the entire world. But the oceans can trigger far bigger, thousand-year freezes. These have the power to trigger mass extinctions and global catastrophes. Worryingly, recent evidence suggests we might be heading towards one of these freezes and, in a bizarre twist, the thing that could trigger it is global warming.

So which is worse -- a big freeze or a big thaw?

Both would be just as bad for different reasons...

If I have to explain it, you wouldn't understand.

You and your infantile avatar are why the ignore button was invented.

It's pretty much accepted as a possibility that there is potential that several symptoms of global warming could impact the ocean currents (sudden inflow of fresh water from melting ice reducing the salinity of the ocean water near the poles is one theory I've heard repeatedly). If the currents were to change or shut down, it will dramatically impact global temperatures servicing to make the middle of the earth hotter and the poles exceptionally colder.

This is a quick read and will 'splain a lot.

Oh boy, I'm so in your face aren't I. Here, I'll change the avatar just for you, or are the penguins to intusive to you?

Thank you.

So, how would you know what makes me feel good?

Global warming, destruction of rainforest and general habitat degradation aside. What do you have against saving money at the gas pump? Or saving money to cool and heat your home?

Either I'm going blind or you posted a Rorschach Test.

i have only read a small part of this, but just because somthing is annoying dousent make it untrue, i get annoyed by rich middleclass men who drive big cars, flying round the world telling us not to fly and drive big cars but the science fairly overwelming, we don't need to stop enjoying our selves just be a bit more sensible with pur enegy use, and invest in low carbon tecnologies
