Are the costs to cultivate and convert biofuels too great? Is it worth all the additional energy, transportation and time?
What’s more important, fuel or food?

Global warming has been in the headlines lately and i have a question. Why is global warming being pinned on people and cars, power plants etc. When global warming trigures an ice age. If thats the case weve already had several ice ages. so couldnt global warming just be a cycle. Cus honestly unless a trex was driving around in a himmer wouldnt an ice age just be a earth cycle?

I read about how the soil of tropical rainforests cannnot sustain intensive farming since they are not as fertile as arable land. It suggests that instead we should now maximise yields on existing arable land instead of clearing tropical rainforests. I would like to ask why can arable land sustain agriculture for so long since the soil has been cleared of its trees anyway and decomposition no longer occurs as frequently which makes the soil degenerate eventually too. Therefore why is it suggested that we should maximise on existing arable lands since by logic they will like the not very fertile soils of tropical rainforest eventually degenerate unless arable land can somehow regenerate nutrients which tropical rainforest soil cannot.

weather or not water vapour is beeing taken into account. Also recently in the artic the highes ammount of snow and ice since records started have been measured.
What does that tell us, that mans impact on the enviroment isnt as big as we thought, or that mans contribution, depsite beeing small in % when compared, is enough to have a major impact on the enviroment, to the point of raising the sea level ?

The snow reflects much of the heat sent by the Sun...

Why are so many people screaming about how the common person should be the one altering there lives to reduce carbon outputs? I would bet that reducing Airline travel would signifigantely reduce carbons so the the coomon citizen would not even have to change their lifestyle. Am I wrong here? I mean, God forbid that Britney Spears wouldn't be able to fly somewhere to get her coffee in the morning.

I've seen so many questions and answers by people who can't seem to understand the difference, and most seem to be believers in global warming at that. Is that significant?

Before you start thinking I'm a weirdo, I live in AZ and the fire control guys have started doing controlled burns up on the mountains for the fall season. WOW, it smells SO GOOD! It's like a big fireplace or a mesquite barbecue and it's making me hungry for a charcoal grilled steak.

Luckily, we had no forest fires in my area this year--last year, there were several--and we had more rain, so the firefighters got a bit of a break. Who else lives in a fire-prone region?

I just saw a fascinating show the other day about Global Dimming, the phenomenon that occured when we were pumping "DIRTY" smoke into the air from our powerplants and cars before catalitic converters and cleaners to reduce polution. The effect of this smoke was a COOLING effect, but it also caused acid rain, and serious health problems.

What the show pointed out was that the reason warming has really sped up in the past 30 years is because of all the steps we have taken to clean up air polution. This cleaning does nothing to the CO2 produced, so the warming started.

Couldn't we develop a safe additive for powerplants that has the same dimming effect as the polution from years ago but doesn't cause acid rain and health problems?

Peak Oil is that piont when half of all the world's oil resources have been used up, and as it gets rarer and more difficult to obtian the price will just go up and up, crippling the economy and causing profound changes that cannot be predicted with any great certainity.

There is no alternative to oil that is not really a derivative of oil, nothing as dense or as energy rich.

After peak oil there will be Peak gas, and without gas you can't process the oil sands and tars to liberate the oil in those. Besides, you need a lot of water for the process, and most of the tar sands are in deserts. Without oil, how do you truck in the water?

Nuclear is not the answer as you can't put nuclear power in a petrol tank, and there is already a shortage of Uranium.

Without oil, how do you build and fit the 32,000 wind turbines you would have to build and fit every year for at least 50 years,
or build and fit the 91,000,000 solar panels needed every year for 50 years. Hydrogen? No.

Our town has just put in a small one and it's very nice, once the Persil suds drain away and the supermarket trolley is taken back to Tescos. In Paris, public fountains abound and all those hegative ions really makes a difference to the atmosphere.

Looking for some sort of Market Analysis. Who are their competitors, market cap, sales figures,etc. They sell wind turbines. IS that a hot product now with the trendy-ness to "Go green" especially in the US?

Zach Goldsmith's plans for 'green taxes' have a fatal flaw, which both he and Calamity Dave Cameron would have discovered had they the wit to carry out any research.

Global warming is a lie!

In fact there is an ongoing offer of a $100,000 reward to anyone who can prove that man made activities contribute to climate change.

There have been no takers.

Polar bears, are doing very nicely, according to The World Wild Life Fund.

CO2 levels follow changes in temperature and therefore cannot cause it.

It was warmer in the middle ages when the Vikings farmed Greenland, and much colder in Victorian times when the Thames used to freeze over.

David Bellamy, Christopher Monkton are just two of the 17,000 scientists who have dismissed global warming as junk science based on computer models that are less reliable than wetting your forefinger and holding it in the air to see which way the wind is blowing.

The Gulf Stream is fine, there has been no abnormal fluctuations in the Earth's climate.

Think about it, we find oil in the deserts, coal and oil and gas under the ice caps, oil and gas under seas, so at some stage in these areas, ( which are either desserts now or snow covered ice caps ) there was once trees and vegitation, for coal to compact, oil to form and gas to be trapped in large pockets. So who caused global warming then ? Wot U Think ?

It would save on energy and would help with polution, why is this not more of a trend? We could do it , and it would be kind of like recycling. The government could give tax breaks 4 this. What do you think. i know not all jobs could do this, but there r a lot that could.

My take is this is hype! I dont see how warming the earth and the resultant increase in water vapor/cloud formation reduces water availability. It may be redistributed but the failing crops etc is mostly hype.
