There is a trend of temperature increase, this is measured reality. But the relation between temperature increase and greenhouse gasses is not well established. There is no science to support a hypothesis that greenhouse gasses are the primary cause of global warming. There is no validated data to support the prediction that future temperatures will increase drastically.
The fear of global warming comes from predictions that future temperatures will increase drastically. This prediction is bases upon computer models. The models have three problems:
1 - There is no long term temperature data from the past two millenia. Accurate global temperature is available only for the past 140 years or so. Temperatures before that, used for input into computer models, are estimates based upon geographic measurements. There are no methods to validat these estimates. In other words, there is no way to know if the temperatures put into models are correct.
2 - Global climate models use mathematical formulas to predict what future temperatures might be. This is where the real fear of global warming comes from. Users of the Global Climat Models predict that, in the future, very drastic global warming will occur. The trouble with this prediction is, that even if *RANDOM* data are input for past history (see the description in 1. above), then the models predict drastic future warming. More simply, the models predict drastic future warming because the equations force it to make that prediction.
3 - *NO ONE* has any data...at all...to determine what part of current warming is caused by either greenhouse gasses, or by natural fluctuation of the sun.
From the site below: "The majority of climatologists agree that important climate processes are imperfectly accounted for by the climate models."

The best thing is to educate!
CO2 is 30% higher than it has been for 650,000 years. Methane is 130% greater. These are two of the main pollutants humans put into the atmosphere in excess, and they are two of the primary greenhouse gases.
Look at the 'hockeystick', which shows a dramatic warming since 1950 after a fairly stable climate for 1000 years. In fact, the 10 hottest years in recorded history have all happened since 1990, with 2005 being the hottest.
(see links below)
How's that for proof of man's fault in this? There is ample proof, any real scientist will tell you that.
There has NEVER been an article doubting man's influence on global warming published in a peer-reviewed journal. A recent study of almost 1000 proved that.
Yes, the earth naturally heats and cools, but the rate and amount we are warming now is unprecedented in the recent geologic past. We are doing this, and we must stop it. This is not some political statement or rhetoric. This is science trying to educate a crass, ignorant public of the damage they are doing. The magnitude of temperature increase ALREADY is about 10x that of the 'little ice age' of the middle ages, and rate and amount are only going up.
Just to be clear, glacial and interglacial cycles are mainly controlled by astronomical fluctuations, but we have a detailed record of the last 7 cycles, and what the climate and CO2 is doing now is way different and extreme. The rate of increase is much higher than in the past AND the value itself is much higher.

1. No - I do not agree with the global warming theory.
2. I think the weather here in CANADA is actually pretty good - even in 20 years, yes - weather patterns have changed but I don't believe it is due to this so-called global warming.
3. We can prevent damage to the air and our planet - because I do believe that we are still damaging this beautiful planet with all the pollution we spew out and our wasteful attitudes - too much of a throw-away society.
4. I don't believe in global warming because of the simple fact that out planet, while it may be in rotation with the other planets around our Sun, it is not a fixed rotation like a wheel on an axle. Until someone can prove of a physical axis that we are secured to (never to happen), I believe that the temperature changes are due to the Earth changing its rotation slightly - why are places on our planet seeing snow for the first time?? That doesn't sound like WARMING to me. Who is to say that while the Earth is in rotation, that it is not slipping out of its usual orbit? I do believe we are depleting the so-called OZONE layer - I have yet to come across anything that proves otherwise - why are there so many new cases of skin disorders and cancers? We never needed sunscreen when I was a child.....

Global warming is a myth, sorry to tell you that. When satellites measure the Earth's temperature, they get the same temperature. Remember, most people only observe a small area, and say that the whole world is warming up. Also, studies show that the world was significantly hotter 200 years ago!
While we may have an especially hot summer, someone else might be having an especially cold winter. So you have to measure the whole Earth's temperature.
Lastly, while some polar ice caps are melting, others are steadily growing! (They never mention that, do they? =)
I hope this helps!

1. No
2. Minnesota's weather is always weird, so I can't answer that. But I do think they weather's changing. I just don't think it's our fault.
3. We can't prevent it. But taking care of the environment is still a good thing.
4. The earth goes through cycles. Everyone is freaking out about nothing. Just think aboutit. How long has the earth been around? How long have we kept a written record of the eather? There is no evidence that we're the cause of what's happening to the earth. It's all natural.

1. The globe is warming, you can see the temperature trends.
2. I live in Florida, the weather has changed over the last 14 years from wet to drier. I think the hurricanes are from the change in weather patterns created by the many volcanoes active around the world.
3. CAN'T - it is a mother nature event.
But we can prepare for our response to the events.

1. yes
2. Texas is very hot and is only getting hotter
3. more fuel efficient cars, use incandescent light bulbs instead of regular ones, replace filters often, unplug stuff you aren't using (most things that are plugged in still generate a lot of energy), insulate your homes well, plant more trees, carpool, recycle, get regular tune ups on your car....
there are many things we can do...and if we all start doing something we can make a big difference

The earth has been warming & cooling for billions of years..
It is currently warming , and has been doing so for about 12,000 yrs.
Man appears to have some influence in the current warming trend but I am not sure as to exactly how much...
I personally ignore the whole "The sky is falling" position taken by
so many self-serving environmentalists ...
Man will adapt , the earth will be fine...

1. Yes
2. Getting worse, but change has been slow.
3. Sequester CO2. Stopping CO2 production is not feasible.
4. You think I am a moron?
