Cyberspies have penetrated the U.S. electrical grid and left behind software programs that could be used to disrupt the system, according to current and former national-security officials.

But fewer than 20 countries account for more than 80% of global GHG emissions; they can be plunked down at a single conference table, as long as it’s at tropical resort. That’s the idea behind the Hawaii Conference. Similarly, California and the 16 states who planned to copy its legislation together make up about half the U.S. population.

Nuclear energy is often touted by its supporters as being cheap, clean and plentiful. It's often stated in articles on the subject that Patrick Moore, purported co-founder of Greenpeace, is in favor of increased nuclear plants. In fact, there are about 30 new American nuclear plants currently on the drawing board. So, does nuclear live up to the claims of its supporters? Well, for one, it might not be as cheap as we've been told. Two reactors planned for Levy County, Florida may clock in at more than twice their original estimate at $10 billion. You can install a lot of distributed solar capacity for that kind of money. In fact Moody's Investor Services gave an estimate in October of $6,000 per kilowatt that Jim Hempstead (a senior credit officer at Moody's) stated in a recent article in the Wall Street Journal has been "blown by" after reviewing recent estimates from a handful of "experienced different nuclear operators".

It does not happen often that I agree with the American Enterprise Institute but Steven Hayward’s analysis of the “real cost of tackling climate change” in the Wall Street Journal of 28 April is spot on: an 80% reduction of greenhouse gas emissions by 2050 will have dramatic implications for our way of life. Hayward has at least the courage (which cannot be said for our politicians) to tell the public what this 80% cut will mean for citizens’ daily lives. In not one political document have I ever seen a serious impact assessment of the 80% target. The fear of being the bearer of bad news is one which characterises all policymakers (even the ones who know that the climate crisis will hit hard).
