- Oil has little to do with climate change , as many factors add to the warming including the demand on food crops and water consumption as the population increases world wide .
So according to some we should do many things, like excluding oil , coal , and natural gas . Well good luck walking back the clock to the stone age . So how does a windmill make out in 70 mile winds ?
I thought once wind speeds reached 45 knots windmills shut down and low wind speeds produce unstable supplies .
Well with the trend of the last few years , it appears stability is not a concern of many. Re-inventing the wheel will be the end result of this anti oil movement , Do you know that ethynol from crops is so backward that land needed for crops is wasted and the price of food is higher due to the demand for corn & sugar cane and so on .
The pollution footprint from ethynol is at least a third higher than oil drilling , but hey , who wants to confuse myths with facts .
Although I will say that deep off shore oil drilling has a huge question mark in my view. - Reply to this comment
- Fossil fuel usage is a modern "progress trap": human extinction is quite possible, due to the abrupt environmental and biological consequences of climate change.

- Good for you CBS for putting this `on the front burner' of the news. Eventually people will get the point and start listening tr
Good for you CBS for putting this on the front burner of the news.
Eventually enough people will get the point and start paying attention to the leadership being offered by your great President. You guys are behind of the central and north Europeans who are already transitioning to what Jeremy Rifkin calls the `Third Industrial Revolution'. Canada, where I live, is falling further behind everyone as we have the worst Prime Minister of this century (and possibly of all time) who has no interest in the topic and promotes efforts by the oil producers of Western Canada to ship their filthy `tar sands' sludge around the world. Fortunately we don't count that much on the world scence if you guys and the Chinese get on board doing something about it. `Stiff Upper Lip; !!! - Reply to this comment
- If we reduce the use of fossil fuels, we not only slow the increase in atmospheric CO2, we reduce pollution and become less dependent on foreign oil. There are SO many positive aspects to using less fossil fuel that we should just quit arguing and DO it. It will not harm the economy it will BOOST the economy.

- I tried so many times to explain to the American people that our system of government here in the U.S. was broken down and indeed woefully out of date. I told everyone repeatedly that our U.S. Constitution desperately needed to be redrafted in favor of far greater democracy, which in turn would take the future power to decide all of these critical issues out of the hands of the corrupt and self serving politicians, and put it directly into the hands of the American people. I repeatedly offered my services to bring this to pass leading up to this 2012 national election, but unfortunately virtually no one was even remotely interested among the general public. I told everyone repeatedly that if this was not done following this next election, then things would probably be too far gone for anyone to save by the time that the next national election rolled around. Tragically no one was interested in anything I had to offer or say, so now I am forced to leave everyone to their own devices from here on out. From everything which I can personally see when it comes to the future there will be nothing but political gridlock for as far as the eye can see. What else can I possibly say but have fun, everyone, and good luck! There is nothing more I can do to save you all from yourselves. - Rick Carter

"Wind turbines now have the capacity to generate 50 gigawatts... enough to shut down 44 coal burning power plants. Enough to power 12.8 million homes.
America is moving into the 21st century and people like the Koch brothers did not get on board, so they are brainwashing fools like you."
Typical liberal response - has to include an insult to make their point. You people have certainly done a great job of helping the liberals to shed that "intellectual" claim you used to make.
A few facts:
Nearly 60 coal fired generators will be shut down this year, but mainly because they are switching to natural gas.
The current wind generation is about 3% of US needs
The US DOE wants wind power to get to 20% of US needs by 2030 (18 years)
To do that, the country needs six times as many generators as already installed over the decade.
The wind power generation is mainly located in the Midwest - a new power transmission grid will be needed to move that power to the east - where wind power generation is minimal in the northeast and nearly non-existent in the southeast.
So, when the US gets to 80% wind power generation - you can call me a fool - but that will likely be near the end of this century.
That was Easy. - Reply to this comment
- The latest reports show the earth hasn't warmed even a tenth of a degree in the past decade, see the IPCC. Second, again according to the IPCC, the percentage of CO2 generated by ALL human, domestic animal, and agricultural activity is less than 4% of annual global CO2 generation. In other words, we could liquidate the human race, and total CO2 emissions would be 96% of what they are now. Scientists and treaties are calling for cutting CO2 emissions over the next twenty years to half what they were twenty years ago, while increasing the =human population by 30%. It's a virtually impossible goal. To reach it, we would have massive social and economic dislocation, poverty, starvation, and death. All to make global CO2 production, man made and natural, more than 98% of what it is right now. Progressives need to come up with better solutions than genocide to solve our problems.

- The only thing he didn't touch upon was the fact that as the oceans warm, CO2 becomes less soluble and the atmospheric concentration will increase. Ice core samples dating back 900,000 years have consistently shown a dramatic increase in atmospheric CO2 FOLLOWING a rise in global temperature. However, we currently have more CO2 in the atmosphere than at any time in the past 650,000 years and certainly, a majority od this is attributable to the burning of fossil fuels by humans. It is a complicated picture and it will be interesting to see what eventually happens here.

- You know what? If the Republicans are right, and man-made emissions are a small effect in relationship to a very large warming result of natural causes, it still remains that the conservative thing to do is everything in our power to minimize the degradation of the planet's habitability. Denying the obvious suggests there are more selfish motives in play, and the GOP is something other than conservative.
When I was a kid, we never worried about the sun, except to avoid sunburns and usually not even then. You never heard of anybody getting skin cancers in the 50s and 60s. Now, the rate of incidence of melanoma has increased five-fold, and one in five of us can expect to contract skin cancer in our lives. Republican solution? Well, cover yourself in whale oil when you go out, and maybe you'll be fortunate. That is a fool's solution. Preserving corporate profits while ensuring the Earth is inhabitable for future generations is not a conservative reaction. - Reply to this comment
