OK, since this debate is fairly civil, here is my POV on the matter.
1. Is there climate change? This is such a poorly defined question that a person with an agenda can easily twist it so the answer suits his needs. However, even if there is a climate change, it is a very minor effect. 20 years of this BS are long enough to refute the predictions of the models from 20 and even 10 years ago. Practically all of them over predicted global temperatures. Perhaps new ones are better, but the track record does not give much confidence in the people are doing them. We’ll see in a few years, because the people of the world will not do anything significant to prevent the forecasted weather change.
2. Assuming that there is a climate change, is the CO2 the cause?
Well, I am not up to date with the new models, but the old ones from 10 years ago were just awful in the way they handled the radiation transfer through the atmosphere. Against intuition, green house gas can only block so much radiation from escaping. When the physics of radiation transfer is done correctly, you get that there is a saturation point beyond which adding more green house gas (co2 in our case) hardly blocks any more radiation. If CO2 is to blame than this has to involve some indirect effect of vegetation or something, but not greenhouse effect.
3. OK, lets say that there is climate change and co2 is to blame- what should we do?
Well, we should do absolutely NOTHING that will attempt to affect the weather. We clearly don’t understand the system and should not mess with it in any drastic way. On top of that, the chances that someone can force the world population to act in a coordinated way towards this goal are zero. Not near zero - absolute zero. Therefore the $$$ are better invested in learning how to live in a world that is 2 degrees hotter than wasted on attempts to prevent that warming. Such a research will benefit humanity even if climate change is proven wrong!
4. So climate change is cow excrement. Should we burn more fossil fuels and release as much co2 as we like?
NO!
Fossil fuels produce actual pollution that is not co2. All this **** about co2 made people forget what pollution is, as opposed to a natural gas that is an essential component of life and nature. CO2 itself is not an issue, but the processes that release it usually involve real pollution in the form of toxins, heavy metals, other stuff that is bad to your health, and ugly stuff that is not recycled by nature (at least on time scales of human generations) that I do not want to see around me.
So emitting less CO2 is good, but low CO2 is not a measure of cleanliness. We absolutely shouldn’t damage the economy in order to reduce CO2. A stronger economy means more resources to fight actual pollution.
