Try running a city during a quiet night with no wind or solar. Every traffic light, every hospital, every factory, every home goes dark. Good for health tho, as everyone who lives in a high rise gets good stair climbing exercise.

to talk science to the few people who don't grasp the reality of E=MC2. I'll stay with the more than 600 readers who like my article.

We don't really know the consequences of returning CO2 concentrations to the levels of the distant past.That is why I get splinters. REW

In the US plants like the AP 1000 run about $5-6 billion each.The Chinese are building them for half that.
An AP 1000 will produce upwards of 500 billion kwh over 60 years which is about a penny per kwh for the plant.
Fuel cost for a nuke is about .6 cents per kwh.
Once built they are low cost to operate in part because of their 90% capacity factor.

Control room testing on the AP 1000 at Sanmen China is complete, and the reactor will be operational in 2014, not 2016. Three more AP 1000s will be operational in China in 2015.
Nuclear energy is high density, reliable, and continuous. It is the low emission future.

As I write this(5 AM Sunday) it is dark and there is no wind. Thousands of heavily subsidized MN solar and wind devices produce nothing.
Yet all over the cities traffic lights function, hospitals have power as do water delivery and purification systems. No one in a high rise is trapped without elevators. Machinery which needs power at a steady voltage continues to hum.
Because down river at Prairie Island four giant turbines are turning 60 times/second, providing billions of...

African American students are disciplined because they misbehave more. It is that simple. Young African American males are in the judicial system in great numbers because they commit more crimes.
They enter elementary school unable to compete and either drop out or fail. They can't compete with children who have two parents who read to them, computers in the home, parents who speak correct English, etc.
We need a strong pre school program to make up for these deficiencies. By...

Sea level rise was rapid as the Wisconsin Glacier(last one) melted. The rise has now slowed to about one inch per decade.
A problem for some low lying areas, but not the catastrophe the article suggests. Warren Buffett, CEO of some big casualty insurance outfits, notes that their rates are stable because there is no increase in unusual weather events. Hurricanes were pure profit in the past decade with no Force 3 or stronger hitting the US. Most of Force 1 Sandy's losses were on...

That's why Buffett only insures them through the government funded flood insurance program. Again sea level rise has slowed to one inch per decade.

No increase in overall tornado intensity. Hurricanes like Camille and Andrew stronger than anything recent. Current drought in West pales compared to longer severe droughts in past few thousand years. No unusual floods.
Ice sheets by definition are on water. When they melt no increase in sea level. Recent study in journal Science showed that net melt from Antarctica and Greenland raised sea level one inch in forty years.
Relax people and don't sell your winter coat.
