At present, the sun is at its quietest. However, Dikpati and her colleagues have calculated that its activity will not only start to rise later this year, culminating in maximum activity around 2010 and 2011, but that this maximum will be one of the most intense every experienced.

'The next sunspot cycle will be 30 per cent to 50 per cent stronger than the previous one,' she said

Suns activity is much more active then it has been. Some scientists have speculated it hasnt been this active for a couple milenia. The increased solar radiation would be enough to massively impact earths eco system, but we also have much more CO2 in the air. So the heat doesnt escape into space. Kinda a perfect storm.

It used to be warm enough in england that you could grow wine. Considering we just came out of a minor ice age (1300-1850) its not odd that glaciers are receding. I often find it odd that people mention the glaciers in the alps are receding when they had massively expanded during that minor iceage. At some points they were growing fast enough to swallow up a couple villages.

Personally i'm not too worried about global warming. Technologies are advancing at such a rate that massively polluting energy sources are being replaced quickly. Look at ireland and their massive wind farms. The rapid advancement in nanotechnology are making solar pannels smaller and 100's of times more productive. Once the sun calms down also the temperature will start to ease. What dislike though is goverment not imposing more regulations on industry to pollute less. Industry's that use coal can reduce CO2 emissions by 95%+ now so there should be no reason to be sending out so much CO2.

Many volcanoes are getting ready to erupt. The massive one near the phillipines (forget the name, cuased the year of no summer) has regrown to the size it was before, and looks like it might go off soon. Once the sun calms down also the temperature will start to ease. Sure things might get a bit bumpy for awhile but it will calm down and cool. Nature is like a bucking bronco, you just got to know when to let go.

Me neither- I try not to worry about things I cant change. You make some good points btw.

did you know that cows create more methane than land rovers create co2 and since methane is potentially a more harmful greenhouse gas then i have come to the conclusion that vegitarians are trying to kill the enviroment

seriously though i too have noticed the total lack of snow... i live in the south west of england so i probably wouldn't get much snow anyway but we used to get about an inch during the winter... now it has been about 2 years since we have had anything more than a slush that melted in about an hour

Vegetarians eat cows?


I think the solution is less "stop all pollution now" and more "find a better way to do things". Pollution is bad whether or not global warming is occurring.

No, the point he was making is precisely the opposite... They don't. :p

We all make methane but I believe CO2 is a more much powerfull green house gas than methane. Before there were Chlorophyta the whole atmosfere existed out of N2, CH4,... The sky was even red because of the big amount of CH4.

Methane is worse. Hence why rainforests pumping the stuff out turns the 'rainforests keep greenhouse gas levels down' thing upside down.

Methane is 23 times more powerful as a greenhouse gas than CO2.

You don't have to be too knowledged about Global Warming to prevent it. Try using products with CFC's less and you'll help.

Can't people live without spray deodorant or hair spray?

CFCs don't cause global warming. CFCs have largely been removed from aerosols.

Well how come that while now there's about 0.032% CO2 in the atmosphere that it's as warm as before chlorophyta while then the sky would have seen red because of the methane. The sky couldn't be looking red from (0,
032/23=0.00139) only 0.00139% of methane, would it?
(I'm not saying you are wrong just find it curious.) of course there's still methane in atmosphere, about 0.00016 if I remember correctly. As 0.00016*23 would be 0.00368. That means the effect of methane on the global warming is about 10 smaller as CO2. But that would also mean that the only a small increase of CH4 would mean a much bigger effect than CO2 would. SO why are all those scientist worrying about CO2? (ofcourse you also have NOx and H2O)

Its been droping in strength since the 1400's. There's about 200 years left at this rate till there is either a shift or we lose all magnetic polarty. Which would turn earth into a frying pan. It isnt certain weather it will switch this time or just die, but since it has happened many times in the past it probably will. Also the reduced magnetic field combined with the increased solar radiation produced by the sun is helping to increase the tempature on earth.

That's what they think. But they can't completly predict how it would go. And it doesn't have to be completly gone for having effect. And yes it will help the world to warm up. But it won't be good for Sattelites, electricty networks, air travelling,...
It would also make a small increase in cancer. Tough this wouldn't be anything spectacular. But ofcourse if the Ozon layer will get more holes and get thinner it might have a 'lil more effect.

hey don't cause it, but they do deplete the ozone layer, which does in turn cause it. You may be right about the CFC's being removed from aerosols, I don't know. I haven't heard anything.

yes, CFC's do react with O3 and thinnen the ozon layer. And the ozon layer filters alot of radiantion but also short-wavelength light. And how more short-wavelength light reaches the earth surface how more light will be transformed into long-wavelenght light. And how more long-wavelength how higer the tempratures. And the increase of UVB and UVC radiation isn't to good either.

That means the effect of methane on the global warming is about 10 smaller as CO2. But that would also mean that the only a small increase of C2H6 would mean a much bigger effect than CO2 would. SO why are all those scientist worrying about CO2? (ofcourse you also have NOx and H2O)

Methane is, kg for kg, 23 times more powerful as a greenhouse gas than carbon dioxide, so if you were to release equal amounts of methane and carbon dioxide into the atmosphere, the methane would do much more damage. The total effect of all the methane is the atmosphere is most likely less than the total effect of all the carbon dioxide in the atmosphere, however.

[Moros]

There's a lot more carbon dioxide in the atmosphere than there is methane, which is why the total effect of all the methane is the atmosphere is less than the total effect of the carbon dioxide in the atmosphere. By my quick calculations, the total effect of the CO2 is very approximately ten times the total effect of the CH4.

yeah I figured that but doesn't tat also mean that a small increase of methane will cause much more effect then an increase of CO2?

Suns activity is much more active then it has been. Some scientists have speculated it hasnt been this active for a couple milenia. The increased solar radiation would be enough to massively impact earths eco system, but we also have much more CO2 in the air. So the heat doesnt escape into space. Kinda a perfect storm.

It used to be warm enough in england that you could grow wine. Considering we just came out of a minor ice age (1300-1850) its not odd that glaciers are receding. I often find it odd that people mention the glaciers in the alps are receding when they had massively expanded during that minor iceage. At some points they were growing fast enough to swallow up a couple villages.

Personally i'm not too worried about global warming. Technologies are advancing at such a rate that massively polluting energy sources are being replaced quickly. Look at ireland and their massive wind farms. The rapid advancement in nanotechnology are making solar pannels smaller and 100's of times more productive. Once the sun calms down also the temperature will start to ease. What dislike though is goverment not imposing more regulations on industry to pollute less. Industry's that use coal can reduce CO2 emissions by 95%+ now so there should be no reason to be sending out so much CO2.

Many volcanoes are getting ready to erupt. The massive one near the phillipines (forget the name, cuased the year of no summer) has regrown to the size it was before, and looks like it might go off soon. Once the sun calms down also the temperature will start to ease. Sure things might get a bit bumpy for awhile but it will calm down and cool. Nature is like a bucking bronco, you just got to know when to let go.

you must not forgetting that the magnetic strength of the earth is reducing too. That means the same sun storms will do much more damage to electric machines and an increase of radiation. that combined with less O3 and more CO2 and NOx, more sun activity. And yes Vulcanoes they will cause to earth to cool down for a while. But don't forget it were volcanoes who ended the two gloabel ice ages which covered the complete earth with snow.

But what I'm also worried about is the amount of nuclear waste in the seas. If you know that 2Kg of Plutonium properly spread can destroy life as we know it...

Quite simply, industries use coal because it's cheaper and doesn't use as much land as wind farms. It's all to do with the economics. Anyhow, coal is going to run out soon.

Is the volcano you're thinking about Mount Pinatubo?

Again, more "earth according to the Discovery Channel (BBC)" on my part. It states that magnetic north is moving again and before long we'll have another polarity shift.

Methane is 23 times more powerful as a greenhouse gas than CO2.

Sunlight breaks down Methane while plants consume CO2 and other pollution. Advanced Urban Planning techniques and bioengineering (which only advanced societies can develop) can help reduce both.

This is an opinion piece I read this morning: http://www.foxnews.com/story/0,2933,188176,00.html

Make all the Polish jokes you want but I’m sure the scientists referenced knows a lot more about CO2 levels than I.

I'd like to see your source on that. Coal is EVERYWHERE in the US.

Edit: oops.
