Breathe shallow if you are a true believer.

Are you blaming CO2 levels on human breathes? Sorry, but the isotopes of the added CO2 match fossil fuels, not human breathe, so limiting human breathes is not going to change the release of those isotopes of CO2.

I vote: stop arguing with people whose notions of the natural world arise from ideology rather than observation.
.

What if those people controlled the congress of the most powerful nation on earth, the nation that would surely need to take a big lead if anything is done to fix the problem? Would it then be OK to present the case (again) for doing something about the problem?

Anyone observed global warming over the last 1000 years?
We have measurements showing CO2 concentrations and temperatures for the last 400,000 years. Nothing back there shows the alarming rise in CO2 and temperatures that we are seeing today.

BTW, I didn't respond to your poll because it didn't ask if we thought if it really isn't all our fault.

OK, the first item in the poll should have said "Anthropogenic (man-made) Global Warming."

Also the word "Yawn" should have been taken out of the third answer. It may be scaring people away from that answer.

I can't change the poll after it is started, so it will need to stay as it is.

I find the polarization on this issue interesting. People are either voting "serious" or "hoax", with not much interest in the "perhaps", or the "don't know so don't worry" options.

We crossed the middle ground a long time ago.
.
The holdouts are simply committed to an ideological program thats threatened by the implications of global warming. (Or so they think).
.
These people will protect that ideological committment at all costs.

Wow the globe cooled overnight. My thermometer is sure lower than yesterday afternoon!

Yeah, as if we didn't have enough indicators that we could stop taking Steve's comments in this thread seriously, this is it.

The funny thing about this is how everyone focuses only on CO2. The man made processes responsible for/allegedly responsible for CO2 production also release a lot of other nasty pollutants. Addressing climate change also helps address those issues as well. Pollution is very real, and linked to very real health concerns. The number of documented illnesses and ecological damages caused by man made pollutants are significant - it's not just about trees cut down for farming. Other than companies who profit by NOT changing their methods, everyone wins if we address these issues whether or not climate change is real. When the argument is only framed in terms of science that frankly most people can't understand, we end up in silly debates. Seriously - on both sides of the issue how many people do you think have actually read climate reports, or understand the models being used? This thread is full of buzz words and catch phrases thrown out by politicians, and that's about it.

Uh, the sunspot cycle takes 11 years to complete a cycle. We have been observing drastic increases in temperature for the last half century. How can you blame that on the sun? We are experiencing a long term trend far worse than the 11 year heat variations due to sunspots.



Uh, we have been between ice ages for 10,000 years. The climate has been remarkably stable during that time. The natural trend would be to go back to another ice age, but it appears that the CO2 we added to the atmosphere is overcoming that, and is driving temperatures upward.

Care to think that over?

Global warming is real, and it is scary. Unless we curb our emissions, it's unfortunate, but we will be facing more extreme weather phemonena.

We may see a greater rate of photosynthesis (more heat increases photosynthesis in plants), so we may have greater crop yields due to the fact that we will have harvests twice a year as opposed to once a year. Not all the effects may be bad, but we can only predict them right now.

I don't see how any Christian can deny global warming because it is predicted in their Bible (Rev. 16:8-9).

The fourth angel poured out his bowl on the sun, and the sun was allowed to scorch people with fire. 9 They were seared by the intense heat and they cursed the name of God, who had control over these plagues, but they refused to repent and glorify him.

That ain't gradual warming. You flunk Bible reading 101 -- and it ain't man-made.

Freezerman, I see you haven't commented on the basic case for global warming per the opening post. Do you deny that CO2 is a greenhouse gas? Do you deny that we have greatly increased the level of CO2 on our planet after the industrial era began? Do you deny that temperatures have indeed risen as the CO2 rose, just as expected?

There are a lot of claims here not supported by mainstream science.

For instance the website mentions temperature changes on Mars, which appears to be a bogus claim. See RealClimate: Global warming on Mars?.

Solar Maxima and Minama cannot account for the rapid rise in temperatures in the last 50 years. See Global Warming and Predictions of an Impending Ice Age: Sunspots — A blog on Environmental Happenings by Dean Bill Chameides

Actually it doesn't. The chart in this paper shows temperatures in the Northern Hemisphere have oscillated about +/-.2 deg C in the 900 years prior to 1900. By contrast temperatures have oscillated over about a 12 deg C range in the last 400,000 years. (see CO2 vs Temperature: Last 400,000 years ) So if historically temperatures have oscillated in a 12 degree range, and recently they have stayed steady within 0.5 deg, that is remarkably stable. That is exactly what I said. So sorry, but you haven't blown my claim "out of the water".

I thought thermometers measured the temperature of a particular spot.

What kind of a thermometer do you have that is able to measure the temperature changes of the whole globe?
