Unfortunately, Obama has already silently been trying to shut the door on nuclear, ...

If that's true how come at least 4 nuclear power plants have been approved by the Obama administration?

Vogtle Units 3 & 4 got $8.3 billion in Federal loan guarantees.

When I was a kid computers were made with discrete components and core memory. Now we put billions of transistors on a stamp sized piece of silicon. There are thousands of people working on the problems you bring up. For large scale installations the cost of solar PV cells is less than $1.00 per Watt and projected to drop to $0.36 per Watt by 2017. Efforts like Elon Musk's battery plant threaten to do the same thing for batteries. (BTW, Musk is a good example of someone with a can-do attitude.)

When the Bush administration took over from Clinton they were warned to keep an eye on Al-Qaeda but they did nothing until a meeting in August just before 9/11. They were more worried about Iraq. Saying the Clinton administration failed to prevent the attack on 9/11 is assuming their greater attention on Al-Qaeda would have not made a difference. That may or may not be true but it's obvious that the Bush administration dropped the ball on Al-Qaeda when they first took over.

There are a lot of naysayers telling us how one thing or the other won't work but we didn't get to where we are as a civilization by listening to them. It's the people with the "can do" attitude that lead us to the future.

While I agree with you about the permafrost cows really do burp more methane than they fart. The reason for that is when cows are out grazing they are doing minimal chewing and just passing it to the first of their four stomachs, the rumen. In there the grass is microbialy fermented which is what produces the methane. When the cows upchuck the fermented grass to chew their cud they burp the methane.

If you're wondering why the cows need the fermentation it's a process that breaks down the cellulose in the grass they eat into more nutritional things like sugars that the cows can digest.

Comment Re:So 30% of 4% is 1.2%. What is attractive here? (Score 1) 281 281

Because all the 1.2% savings that can be made add up to make a large difference. If we find eight ways to make 1.2% savings across different areas then that is nearly a 10% reduction in the human generation of greenhouse gases. The human race isn't limited to finding just one method to solve the climate change problem. If we make small savings across the board with cost-effective, manageable solutions then we don't have to solve the problem with a single grand gesture that ends up costing a lot of money.

In the long run reducing methane emissions by livestock doesn't make any difference. The methane they emit comes from carbon that was already in the active carbon cycle when the plants they eat absorbed it from CO2 in the air. Methane breaks down to CO2 in a relatively short time scale (20-100 years) in the atmosphere and so gets recycled back into the plants eventually with no net change to the amount of carbon in the active carbon cycle. The only real long term answer is to stop adding additional carbon by stopping the burning of fossil fuels. Anything else is just putting lipstick on a pig.

We may cover less than 4% of the Earth's surface but the US is still directly responsible for about 15% of the worldwide emissions of CO2 (as of 2013). Plus you really should include the indirect emissions of other countries that are driven by US demand for the products they produce.
