UN: Renewables, Nuclear Must Triple To Save Climate
An anonymous reader writes "On the heels of a study that concluded there was less than a 1% chance that current global warming could be simple fluctuations, U.N. scientists say energy from renewables, nuclear reactors and power plants that use emissions-capture technology needs to triple in order keep climate change within safe limits. From The Washington Post: 'During a news conference Sunday, another co-chair, Rajendra K. Pachauri of India, said the goal of limiting a rise in global temperatures "cannot be achieved without cooperation." He added, "What comes out very clearly from this report is that the high-speed mitigation train needs to leave the station soon, and all of global society needs to get on board."'"
The long and short of it..we're buggered. Thankfully, we will all be dead when it gets really shitty. If you think that the countries of the world can band together to reduce emissions and turn to renewables, you are smoking the funny tobacco. I install solar in countries that have the highest electricity prices and the most sun, but they refuse to implement renewables, preferring that good old diesel products. People are inherently stupid, short sighted and greedy. Nothing but war and pestilence will cause change. Nothing else ever has.

Nuclear is cleaner than any fossil fuel, properly managed. Overall, despite the accidents, nuclear's impact has been a lot smaller than that of fossil fuels.
Unfortunately, accidents aren't seen as an opportunity to learn and eliminate old flaws, but to halfheartedly dump the whole thing, leaving behind ancient designs with known flaws instead of new, safer designs.
Human minds just aren't made to react to something so abstract, so distant, so far away. Look at the crisis building up with the US economy, national debt, and so on - something that could cause a whole generation to undergo a great depression yet nary a thought is given to it.
For example, on the economic situation, this guy was made the US's top accountant for over a decade, and appointed to posts by both R and D presidents and yet he makes videos that can barely garner 2k views about the situation (since September):

I guess if there was a girl twerking in it, it might work.
Anyway, that's how it is. We react, many don't think too far ahead. Both situations are basically simple concepts in theory (global warming is built on the green house effect which is simple to demonstrate, the economy on interest and other high school math), but so many interests go in and muddle issues, that the average guy doesn't know what to believe, so even those with a modicum of forethought are stymied by special interests.
And the special interests want status quo. Nothing will happen. That's the tragedy of democracy and why it never really lasts long. Power and money is like water, it always gathers and concentrates.
France imports electricity from Germany whenever it's too hot or too cold. In either case, limited cooling is available. In the winter, this is exacerbated by the enormous consumption due to the French preference for electrical heating combined with a lack of insulation, because electricity is cheap for consumers in France. Besides, the argument that stopping construction of new nuclear power plants is the reason for older designs remaining in service is bogus: Older designs remain in service no matter what (except for a total ban, which is happening in Germany). Keeping old plants online is simply the capitalist thing to do: They're bought and paid for and still work. Why would you shut them down?
Old stuff. Pebble bed reactors have their own problems. This one had atmospheric releases of radioactive material, contaminated the ground and groundwater below it (complete with increased Leukemia rates in the vicinity) and is currently much more radioactive than planned so that deconstruction can't begin: AVR Jülich. This one was decommissioned after just six years due to the continuous repairs driving the costs up: Thorium High Temperature Reactor 300MW.
The nuclear industry will always try to convince you that the solution to all nuclear power problems is waiting right around the corner, to convince the public that nuclear is still an option. Whenever and wherever they're allowed to continue, not only do they keep the old designs online, the "new" designs never deliver on the promises either. They keep covering up accidents, they keep playing down potential risks, they keep deferring risk to the public (nuclear power plants are uninsurable: if - when - the shit hits the fan, everybody pays the price, in more than one way.)
Nuclear is cleaner than coal barring an accident. Coal is guaranteed to kill and hurt people. With Nuclear you at least have a chance of everyone being healthy.
I beg to differ: nuclear is cleaner than coal even if you include accidents. The calculations on that page are admittedly from early 2011, but it accounts for 4,000 deaths from Chernobyl. I could add up a bunch more from Wikipedia, but screw that, lets just throw in Hiroshima and Nagasaki into the mix - about 250,000 deaths. And then let's round that to an even one million for the heck of it.
The death rate is still lower than coal by an order of magnitude. Nuclear is cleaner than coal even if you include 4x the deaths of atomic acts of war.
That whole piece is fascinating, especially for insights such as
Coal and fossil fuel deaths usually do not include deaths caused during transportation. The more trucking and rail transport is used then the more deaths there are. The transportation deaths are a larger component of the deaths in the USA than direct industry deaths. Moving 1.2 billion tons of coal takes up 40% of the freight rail traffic and a few percent of the trucking in the USA.
and
Those who talk about PV solar power (millions of roofs) need to consider roof worker safety. About 1000 construction fatalities per year in the US alone. 33% from working at heights. Falls are the leading cause of fatalities in the construction industry. An average of 362 fatal falls occurred each year from 1995 to 1999, with the trend on the increase.
I live in constant fear of the Coming of the Red Spiders.
You need to look no further than Germany renewables plan, flush with hundreds of billions of euro in funding has stalled. They can't add more wind or solar panels to the Germany grid. The problem isn't money. Every extra solar panel and wind turbine added to the grid increases grid instability a little more.
When are you environmentalist nuts start studying how the electrical grid actually works instead of having fantasies about how it should work.
If solar and wind were so great, Hawaii would have shutdown its oil based thermal plants already. They have very expensive electricity, making renewables cheap, yet it doesn't quite work, cause it's just not that simple.
Get a grip. Without nuclear, there's no hope to solve climate change. And nuclear is not the boogeyman your environmentalist friends have convinced you it is. Zero Fukushima deaths, zero confirmed radiation related cancers. Its been three years. It's already becoming another Chernobyl (as in the environmentalists overblow the problem about a thousand times).
Until the environmentalists show they understand the actual impact of nuclear accidents, accurately predicting the effects of nuclear accidents, in my view they are a bunch of looney tunes alarmists that should be given ZERO credit when the subject in nuclear power.
It's not even all of the environmentalists, check out Patrick Moore:
http://en.wikipedia.org/wiki/P...
He used to be the President of Greenpeace and was *ahem* asked to leave, primarily due to his advocacy of Nuclear Energy
At this point Greenpeace is as stuck in its position of advocating against Nuclear Energy as the NRA is against gun control, and they are both looking like obstacles to any positive change in the status quo
By working against Nuclear Energy, Greenpeace has managed to be as big a supporter of continued fossil fuel dependence as the Koch bros.
There are plenty of smart environmentalists out there, and the uninformed ones should be donating their money somewhere besides Greenpeace
Wherever You Go, There You Are
Nuclear power on the other hand scares the hell out of me.
Learn about it. I've found that in doing so, I have become far less frightened of it.
You are clearly an intelligent person, which is what makes this so sad. Your post is full of errors which the actual facts you claim to believe have proven to be false.
1. The medieval warm period affected just the northern Atlantic area - it was not global, and so is rather irrelevant in this discussion without you also discussing the rest of the world's climate during this period. It was also colder then than now, so it's rather pointless to even bring it up in discussion.
2. The Himalayan glaciers *are* receding. It sounds like you are paraphrasing Christopher Monckton's claims that they are not, which is strange, as the man himself has recanted that particular belief in face of overwhelming evidence to the contrary. In fact, they've been receding constantly, at least since satellite data has been available to demonstrate that fact.
3. Global cooling was not a scientifically-accepted hypothesis in the 1970s. It was, however, trotted around in the media for sensationalism, which is where this idea comes from that it was the scientific consensus at the time, when that is demonstrably nonsense.
4. Since the early 1900s, 80% of the ice on Kilimanjaro has disappeared. 80%. To say that the ice (which, colloquially, is what "Kilimanjaro's Snow" refers to) has not receded is patently false.
The source for your facts clearly needs some adjustment, as you are parroting the same debunked nonsense the anti-AGW crowd has been trotting around for years now. The facts are there - you don't seem to be wanting to look for them.
Canada's topsoil in the areas which will warm up were scraped away by glaciation, meaning those areas will be next to useless for crops. Siberia's permafrost contains a lot of methane, which will be released into the atmosphere if it melts, which is a potent greenhouse gas, which will cause even more warming. Its topsoil also isn't great for farming, plus the industry, skills, and workers required to farm Canada and Siberia's non-existent suitable farmland isn't in either Canada or Siberia, which is a bit of a problem for your notion. That spreading north of suitable climate for growing crops means that huge swathes of the US will no longer be able to produce crops, which doesn't sound like a good situation for the US to be in.
But whatever - you have your "facts", so I guess we can just ignore this stuff forever, with no ill-effects. Right?
