"Climate change means we must change"

Cuban permaculturist Roberto Perez, one of the keynote speakers at the Climate Change|Social Change conference organised by Green Left Weekly in Sydney April 11-13, explains how the world can learn from how Cuba confronted its "Peak Oil" crisis in 1991.

Damn...he got fat!

[JonThm]

New Scientist said 3.7 ppm. I say do molecular nuclear fusion, power with no CO2: Don't you aggree? So no globla warming, but the next ice age is with us anyway. Or don't you look out of the window very often?

[KingMucktoad]

More Co2 does not equal more life on earth test show that mor Co2 makes plants less grow less healthy, which disrutps the food chain.

Humans do put out very little Co2, however all other sources have found an equalibruim with the planet, ie. oceans take out what they put in.

its not 3.7 parts per million it's 370 parts per million.

"We should get all our power from molecular nuclear fusion"

Absolutly we should then we wouldn't have to have this discussion, would we?

[JonThm]

There is 3.7 parts per million of CO2 in the air, whic his pegged by plant growth. More CO2, more life on Earth. We should get all our power from molecular nuclear fusion - getting power vfrom water, with no CO2. So man puts out0.0000000000% CO2. Even CO2 is not that potent! Infact, it isn't potent at all!

[JonThm]

Things change! Man should do molecular nuclear fusion, and generate power with no CO2! Just a whiff of He, like the deep does so much! So no GW: Adn man is off the hook for climate change - nature does it, we cope with it!

[KingMucktoad]

its acctually .0037% co2, not .00037% but you missed the most important part.

our atmosphere is:

78% nitrogen

21% oxygen

.9% Argon

Thats 99.9% of our atmosphere right there and heres the kicker.

None of those 99.9% are greenhouse gasses.

So a little bit of Co2 goes a long way, hence the problem.

excellent, thanks for this video

I don't think you read my comment. I wasn't even going to get caught up in the 'climate change/warming' debate. There are a million of those going on, i couldn't be bothered. You said we do not make the weather, i said we have a large impact on it. Ask a Haitian if humans had an impact on their climate.

I have picked up the salty, sandy earth in Lebanon, Jordan, Egypt, areas that were once the fertile crescent, what are they now? We did that.

That is one part of my academia.

[JonThm]

Histroy shows that CO2 tracks the weather, it does not cause it. THere in 0.00037% CO2 in the air, 2000 times to little to have any effect: Data learned on a PhD. What academic level are you, or do you just believe the media?

[cmurkar]

what are you talking about? Firstly, I didnt hear him mention nuclear power. Second, humans have a very large impact on the weather. Even if you dont want to admit, or discuss fossil fuels, at least realize that when we deforest large parts of the world, we are impacting the climate. Learn at least the basics of ecology, the functions/impact of trees/forests on the weather, and then stop posting such absurd comments.
