Nothing is more essential to life than water. This fact does not make floods less deadly and harmful.

I don’t think anyone is claiming that natural cycles of CO2 are dangerous to life.  The concerns are the effects of burning billions of years of stored carbon in a hundred year period.  What is amazing to me are all the externalities associated with the burning of carbon that most people don’t even realize.  One example is that my pregnant wife can not eat certain types of fish due to the high level of mercury contamination.  In my opinion a lot more needs to be done to reduce pollution levels and we cannot rely on the government alone to accomplish this.

Soon the human population will expand to 9 billion.  With the increasing industrialization of developing nations, many important resources will become scare. The desperate desire to maintain economic prosperity will cause incredible damage to the ecosystem in order to extract the remaining resources.  There will be wars and starvation. The quality of life in industrialized nations will plummet to the level of developing nations.  The population will drop somewhat to a level that is just barely sustainable. As the damage continues, that level will become lower. The world will not be a nice place to live for a long, long time.

You should have the right to abuse your environment anyway you want without the interference of any sort of regulation.  Chop down every tree, drain every pond and swap, and tear up the terrain to dig out the coal, oil and minerals and then pave it over with roads, shopping centers, more houses and parking lots.  Corresponding to you there are another 20 people in the world right now wanting the same things you already have. Perhaps you are young and will get to see all this.

"I don't know how anyone can take CO2 seriously after the last few weeks"

Some call it faith; I call it intellectual dishonesty.

Yes AGW and the scientist who discovered it may very well be put on trial, not unlike Galileo when he claimed that the earth was not the center of the universe. The heresy now however is not declared by the church but by the fossil fuel industry.

wow, just where did you climate deniers get your education, from a cheerios box? Was it a coupon or a toy.  You talk about science as if you know nothing about it.  It would be nice to keep the discussion to science and new technology that doesn't cause the deaths of 60,000 to 100,000 American citizens every year as is the case with coal.  How patriotic is it to want those people to keep dying?  Then add in scores of thousands  more dead Moms, Dads, and Kids from burning gasoline and diesel.  We need solutions to all these  deaths, and they don't come from oil, or coal, or depleting the soil, or nuclear reactors that simply bankrupt and physically threaten a thousand future generations. Political parroting for oil and coal driven political positions, only continues the unspeakable killing of our own people for profit. We can do better than fossil fuels and we can do better than nuclear.  Just to cart ourselves and our Walmart goods around we have fought a constant battle in the mideast ,, both directly and through proxies, since WW1.  Clean energy is energy that doesn't kill us, and has no hidden costs in life or costs.
