    Evidence for what? Global warming or man made global warming?

    Absolutely the climate is warming, but the big debate is whether its man made and what the long term effects are.

    I took a class entitled global climate change. There is definitely warming occurring and it is definitely being accelerated by humans, but currently the affects are not very significant. The real danger is in the accumulation and gradual effect on the atmosphere that will continue to get worse for years and years even if pollution were to stop immediately.

    As far as long term effects, the biggest problem is the ice melt. Not only is it effecting the cultures that live in the northern areas, but the resulting input of melted land ice into the ocean is causing a slow sea level rise. There are specific calculations that can be done regarding how high the oceans could rise based on the percentage of the ice sheet that melts. Right now there is a very small annual increase, but it is consistent and given the fact that the majority of the worlds populations live near the water, it is only a matter of time before it begins to effect our structures. The Navy is already going through some of this with their bases... Norfolk is in a lot of trouble.
    Secondly, the ozone hole gets bigger every year. This may not seem like a big deal, but it does a lot to protect us. The size of the hole is directly related to all of the gases that humans release into the atmosphere. The problem is that these chemicals react with the ozone causing depletion of the layer.

    The Earth's climate has changed drastically many times over it's life span. It will change many more. Hair spray or no hair spray.

    We could stop all our pollution right now and the global warming would continue at approximately the same pace...We prob'ly contribute less than 1/1000 of a percent to the warming trend so many people seem to think we are the root cause of. Mt St. Helens put more 'pollution' that contributes to global warming, into the air in ten minutes than all of the industry in the world put into the air in the previous ten years leading up to the eruption. Wonder how much the volcano in Iceland put into the air when it shut down europe for those few days in 2010?
    They say the ash fell out of the air fairly quickly but the water vapor was the main culprit for the airline travel etc. What about the gases emitted when burning whatever material to the amount of ash that was released and creating the huge amount of water vapor from melting glaciers?

    btw -You could argue that we have been warming since the year without a summer in 1816....but that would rule out the industrial revolution as the culprit.

    I personally am a believer of humans contributing significantly to climate change. Take a look at the arctic ice levels, its disappearing at record rates which = no more polar bears = \

    Wolvenkinde, you may not believe it, but science is behind it. all you have is your 1/1000 percent that you made up. And no we are arguing that its been going on for longer han 1816, its just been accelerating recently with all the polutions, CFCs, CH4, CO2, etc.

    you are fight the 1/1000th is a made up number...I am not going to do the math but what is the actual ratio when you compare the amount of emmisions from Mt St Helens to 10yrs worth of the industrial world(in the 1980s...with less polution controls than now). Sure seems to me that it makes 'our' contribution to the grand scheme of things pretty miniscule. The fact is that global warming has a snowball effect...as ice melts(and get this), it is exposing organic matter(where from? - from ancient plants that were there before the ice cap) that is being exposed to the elements/air and thereby starting to decompose, releasing CO2 and Methane into the system thereby exponentiating the global warming, as it thereby exposes more organic matter(that was covered by ice that was not there when the plants grew there originally)...and on and on. This btw is just one small section of the natural cycle leading to climate change. I am not saying we don't contribute but to have such grandiose ideas that we have so much impact or manipulate the climate is ridiculous.

    None of us are getting out of this alive. Don't believe all the hype.

    How about all the stuff that happened to the planet before we got here and so smart? Who's catching sh!t for creating the Grand Canyon? Native Indians?:) yeah!

    Over the last 4 Billion years, our planet has wamed and cooled multiple times.

    The problem with these global warming nuts, is that they are looking at such a short timeline for comparison. Our planet was in an ice age as recent as 10,000 years ago.

    Our axis wobbles, and our trip around the sun is elliptical in shape, and it is not always the same track from year to year. Solar climate impacts that path a bit as well.


    My philosophy- Try to do the right thing, do not abuse Mother Earth. When she is tired of us humans and our shenanigans, we will all be evicted. She will heal herself and move on.

    Actually, science is not behind global warming being man made. Quite the contrary.

    My sons science teacher definately isn't behind it. My son told me last night he said we are coming out of another ice age and just like everytime before, it gets warmer.:)

    Keep in mind that a lot of teachers are quite liberal in their political and social beliefs. A professor at the University of Wisconsin was even allowed to teach that 9/11 was entirely orchestrated by our government and President Bush as an inside job. Not everything you hear from teachers or read on the internet is true.

    The polar bear population decrease is incorrect. Its just used to trigger human emotion, populations are doing fine.
