Welcome to Gaia! ::

-----------------------

I recently saw "An Inconvenient Truth" and I have stronger beliefs of global warming. There are more and more TV shows coming out about global warming like 6 degrees can change the world and The day after tomorrow and even books like The Final warning. The ice caps are melting rapidly and by 2010, almost all will be gone. What do you think about global warming?

-----------------------

Global warming is a serious issue that nobody completely understands given the enormous scope of the earth-system and huge time spans involved. It is also countered by other major earth-changes. Global dimming, in a way is the opposite of global warming, being that industrial pollution blocks sunlight and cools parts of the earth. I saw a television special describing how pollution from North America and Europe blows over the oceans, decreasing solar evaporation and reducing the monsoon rains in Africa and Asia, therefore contributing to drout and human starvation. Another interesting point of the issue is the CO2 itself. I have heard before that scientist believed that increased CO2 might simple be seized by faster plant growth, since CO2 is a relatively small component of atmosphere by percentage. But then the Discovery channel had a special on dinosaurs where a paleontologist explained how core samples from Jurassic period sediments revealed CO2 concentrations far higher than we see today. This scientist tested a hypothesis where he grew plants of the same type in identical soil, but one group in an atmosphere of artificially high CO2. The result was that the plants exposed to higher CO2 concentrations did indeed grow faster and larger, but at the expense of being "less nutritious" meaning it contained more cellulose plant fiber and less protein and other organic substances animals need from food. This supported his theory that high CO2 concentrations (in this case probably from volcanic erruptions) caused plants to grow larger and less nutritious and required animals to in turn become larger to consume enough of them. In short, it was elevated atmospheric CO2 that ushered in the age of dinosaurs! The Earth is resiliant to change, but can respond in unpredictable ways.

Global warming is a definite issue that needs to be addressed by governments and companies.

However, how much of global warming is man-made remains to be determined, but of course it's still bad the envirioment, and us....Anyone been to Los Angelas lately? Smog is horrid....and that was when I went there 3 years ago.....
Natural cooling and warming trends have always happened in the Earth's history, and it normally corresponds with things such as the Milankovich theory. This theory states that the overall temperature of the Earth is dependent upon Earth's non-constant eliptical orbit, the time at which the earth's seasons are during the distance from the sun, and tilt of the Earth which is also non-constant, Earth wobbles between I think 24 and 22 degrees every couple of hundred thousand years. We are in the 23.56 tilt degree right now I do believe...I'm pretty sure at least.

But of course there are many different contributions to the climate of course, Volcanic gases cooling the Earth, Changes in ocean currents, ect.

In fact that is one of my largest concerns about Global warming, the melting of Arctic Ice changes Salinity densities which therefore changes the overall densities of ocean water disrupting up welling and down welling cycles that would essentially affect many deep ocean currents. The Gulf stream for example my change course, or just dissipate altogether. Altering the climate of western Europe, as many know the gulf stream brings warm water from the gulf of mexico to Europe, and this warm water helps this warming effect....without that warm water, England and other countries will be as cold and snowy as places like Canada and parts of Russia. This could affect food supplies, worsening food shortages and increasing prices.

And that's just one possibility.



That royaly sucks, Gas here is just under $4, yeah, the Oil Companies and their Greed is really getting on my nerves. I'm just gonna get an electric unicycle and be done with it, max of 40mph, but I donn't plan on leaving the areas I live in very often so....Which on a side note, if you guys haven't seen that thing, it looks kind of like a segway on steroids(different maker though)and it works like a Segway as well, lean forward to accel. and lean back to slow down, then lean to the left to make a left turn. It's cool.

Global warming is not something that happens overnight, and due to the large number of people who die at any given time for any given reason, it is unlikely 'some people dying' will draw anyones attention. Besides global warming doesn't kill. Environmental changes due to global warming may.

We just had the worst lightning storm of the decade and I strongly belive it has to do with global warming. The lightning and tornado got way too personal for me not to do anything about global warming. (Lightning hit our house and shattered the windows from the pressure jump. It caught the house nearby on fire too.)

I don't believe in Man-made glo-bull warming either....go ahead burn me as a witch..."oh noez!!!!!1" Logical Evidence...So evidence that shows warming is logical and if it doesn't its crap....Oh my! Whatever happened to people who actually used the Scientific Method. I would rather be thick and obtuse than be thick and be square. Us skeptics do not deny global warming....It is happening...we just don't think that man is causing it because the sun and natural fluctuations are much more powerful. Also the medieval warm period was warmer than now and resulted in fewer diseases, longer growing seasons, and overall a healthier world.....I could go on but everyone in the world that clings blindly to what has basically become a fake religion will ignore me....."How stupid they'll feel when the world yet to come is no different"-Directorio99, My friend and a certified Climatologist.

I most certainly hope you didn't base this off his faith. There will be none of that in here.



Wait a sec. doesn't your other thread on this subject testify that the earth is cooling?
