At this point it isn't worth debating with those who deny global warming or humanities large contribution.
At least Obama see the reality, and recognizes we need to start somewhere.
That being said, the global carbon tax idea is a really bad idea. We need and effort like NASA's race to the moon. We need toake major changes to our infrastructure, and the way we do business as a society. A heat deal more effort needs to be made to create create change models so that we can take some pre-action.
If we don't do it sooner, than we will be forced under extremely bad conditions to make these changes sooner.
That Obama recognizes that this change is happening, while Romney is a denier, should convince anyone still among the undecided, who recognizes that Global Warming is a fact, to vote for Obama. By the next POTUS election, this will probably be the biggest issue we face. The good thing is that there will be no shortage of work.

EVERY scientific organization in the world says that humans are directly responsible for the world getting warmer. Then why do they prefer “climate change” to “global warming”? Scientists are exact and love precise terms. Actually they are very en.wikipedia.org...
Here is an explanation!

Grrrrrr!
Tell me something I don't know.
Why do people jump in without reading, assumptions don't get us anywere except confused.
THERE IS LOTS OF LIFE ON EARTH!! OVER SEVEN BILLION HUMANS!
If you want to stay dumbed down.... Be my guest. It does sadden me though there are so many people who don't get what their/ our role is in this Universe.
How Much Solar Energy Hits Earth?
Posted on 14 June 2006.
If solar power is the purest form of renewable energy known, then how much solar power have we got? The answer to this question, when considered alongside how efficiently we can convert raw sunshine into usable power, helps determine whether or not it is realistic to consider solar energy as a viable alternative to conventional energy sources.
In full sun, you can safely assume about 100 watts of solar energy per square foot. If you assume 12 hours of sun per day, this equates to 438,000 watt-hours per square foot per year. Based on 27,878,400 square feet per square mile, sunlight bestows a whopping 12.2 trillion watt-hours per square mile per year.
The Sun
With these assumptions, figuring out how much solar energy hits the entire planet is relatively simple. 12.2 trillion watt-hours converts to 12,211 gigawatt-hours, and based on 8,760 hours per year, and 197 million square miles of earth’s surface (including the oceans), the earth receives about 274 million gigawatt-years of solar energy, which translates to an astonishing 8.2 million “quads” of Btu energy per year.
In case you haven’t heard, a “quad Btu” refers to one quadrillion British Thermal Units of energy, a common term used by energy economists. The entire human race currently uses about 400 quads of energy (in all forms) per year. Put another way, the solar energy hitting the earth exceeds the total energy consumed by humanity by a factor of over 20,000 times.
Clearly there is enough solar energy available to fulfill all the human race’s energy requirements now, and for all practical purposes, forever. The key is developing technologies that efficiently convert solar power into usable energy in a cost-effective manner.

Actually no! The climate science skeptics (convinced by Koch bro’s propaganda) have neither science nor rationality on their side. I find it amusing that so-called “conservatives” (they are not conservative. They want international corporations, ala Koch bros, to have all the say so and ridicule individual freedom) have become en.wikipedia.org... ! Since the science is ALL against them, they claim that it is all opinion anyway! Considering that postmodernism was a liberal movement, that shows how the Romney “conservatives” are hypocrites!
There is an objective reality!! No matter how much Romney denies it!
Following the new record low recorded on August 26, Arctic sea ice extent continued to drop and is now below 4.00 million square kilometers (1.54 million square miles). Compared to September conditions in the 1980s and 1990s, this represents a 45% reduction in the area of the Arctic covered by sea ice. At least one more week likely remains in the melt season.
