I have an inter-school science fair coming up and I need to make a project on "Energy conservation". I really don't think that making something like a solar cooker will help me win, as my teacher needs something "big". Can you please help??? Do you know any sites that will help?

The predictions say that in about only 100 years the poles are going to melt. Everyone will loose their homes, animals will extinct and plants will disappear... Carbon Dioxide will heat up the earth, weather will change, with no plants oxygen will decrease, how will be survive? There is no other planet capable to sustain life to go! even with the technology it is impossible, 100 years are just around the corner, I am 23 years old + 100 years = 123, I wont see it, but I will witness the beginning of the 8th mass extinction episode of earth... my kids will live on it, and my grandchildren will have to live through it. Why we keep killing our planet and our future generations... this is murder!!!!! STOP! Green house gasses...lets put a end...

Me and my friend are wondering if anyone thinks global warming is true. If you think it is give us some feed back on why it is. Thanks

I can't find any recycled (made of old papers) office paper (A4 paper sheets) in Swedish shops. As an environmentally concerned person and a member of a university environmental group, I want to influence the university's departments to start using recycled paper for their printing purposes. But if there's not recycled paper on the market, how can we make it happen?

Seeing That the Howard govenment has its head in the sand of the last 11 years, should the average Coastel residents be worried about the violent storm's that will be the norm if there is nothhing done to combat this change, I do know that it is global, but someone has to make a stand before its too late,No amount of money is going to change conditions of the planet if there is nothing being done by the most Industry rich countries, they should be the first do it, and not wait for someone else,

If the storms that are appearing now , and coastel cities will bear the brunt of such wild weather that has never been seen before, The sea will rise, and no amount of protection on the area where they live will not protect them.

If the sea turns nasty anyone living on those area's will be hit hard , and very Hard at that. soil erosion , where will their houses go, reclaimed by the sea, it will rise you know,

With such wild wearther that is appearing of late .should you be worried

On possible drivers of Sun-induced climate changes
de Jager C, Usoskin I
J. Atm. Solar-Terr. Phys. 68: 2053-2060 2006
Abs: We tested the validity of two current hypotheses on the dependence of climate change on solar activity. ... Therefore, we can conclude that in so far as the Sun-climate connection is concerned tropospheric temperatures are more likely affected by variations in the UV radiation flux rather than by those in the CR flux.

Aerosol nucleation over oceans and the role of galactic cosmic rays
Kazil J, et al.
Atmos. Chem. Phys. 6: 4905-4924 2006
Abst: We investigate formation of sulfate aerosol in the marine troposphere from neutral and charged nucleation of H2SO4 and H2O. ... the variation of ionization by galactic cosmic rays over the decadal solar cycle does not entail a response in aerosol production and cloud cover via the second indirect aerosol effect that would explain observed variations in global cloud cover.

I have an essay due in science about renewable energy. Just like to gather some opinions on these topics, please do contribute, even if its only saying "I agree with so and so" :)

What are some advantages and disadvantages of using:
1) solar cells (photovolitiacs), which use semiconductor materials to convert sunlight into electric current
2) wind turbines
3) biofuels, such as green diesel and lignin

What steps do you think can be taken to increase the use of renewable energy sources? How would these steps help accomplish the goal?

Thanks so much, your opinion helps! As I said, please answer even if you're only agreeing with someone else! I need all the feedback I can get! :)

Several Alaskan villages are falling into the sea. This is mostly due to global warming. The permafrost (ground that was permanantly frozen) is melting and the buildings are sinking. Rivers are overflowing. The ice that would form on the shore and protect it from storms is forming later each year.

Here is an example - look at the two pictures, the first taken before a storm and the second one after a storm. They were taken from different angles, so it is hard to look at the shoreline and see the change. Look at how close the metal trashcan is to the edge in each picture.
http://www.arctic.noaa.gov/detect/human-shishmaref.shtml

The cost to relaocate the 3 villages that are not expected to last 10 years:
Shishmaref, ~600 people, up to 200 million dollars
Newtok, ~315 people, up to 130 million dollars,
Kivalena, ~380 people, ~125 million dollars.
These are just the most serious cases.

An oft-used AGW skeptic argument is that humans and SUVs weren't around hundreds of thousands of years ago to cause prior climate changes, therefore we can't be causing the current change.

Another skeptic recently commented that it's "an eye roller" to think that this is the first time climate change has been initiated by an "unnatural" cause (human GHG emissions).

The first argument is obviously illogical - the fact that humans have not caused climate change in the past does not mean we can't be causing it now.

The second argument puzzles me. The fact that our greenhouse gas emissions have been skyrocketing since the Inudstiral Revolution seems to me that they're a logical potential cause of the current climate change. The fact that according to natural cycles we should be in a cooling period right now, combined with the rapid acceleration in both human GHG emissions and global warming seems to make this an obvious candidate.

So why is this theory "an eye roller"?

The Holocene maximum peaked about 6000 years ago. It was much warmer than it is now and it lasted for about 4000 years, but the ice cores show that Ice existed on those continents for more than 500,000 years.

Personally I don't know of any liberal AGW skeptics. I'm sure they exist, but I've never met one. There are certainly a lot of conservatives who agree with the AGW theory (famous ones like Bush and Gingrich and Huckabee, even some who frequent Y!A), so I wonder why this isn't the case for the opposing viewpoint.

So I'm curious if anyone here knows a liberal who is skeptical of the AGW theory. If not, why do you think the theory is so universally accepted among liberals while there's so much of a divide on the issue among conservatives?

Go to junkscience.com and prove scientifically that man is causing global warming.
Should be easy unless.......

that theory is just capitalist hating idiots exploiting brainless blind faithers.
