Industry bottlenecks will delay any reactors for years, maybe longer

Kind of an important point:

It turns out that Osaka-based steel-making giant Japan Steel Works Ltd ... is also the world's only maker of ultra-large forgings, a crucial component in the construction of most new nuclear reactors ...

Japan Steel, for example, is currently equipped to supply only five reactor forging sets each year, with each set including an ultra-large forging.

So, the nuclear industry that shills sources have assured us is ready to leap in to action with ridiculous modest subsidies to avert global warming can currently build a grand total of ... five reactors a year?

That's a little short of one a month.

IPCC likely too optimistic about recoverable coal

Anyone interested in the climate should watch this talk by Professor David Rutledge from Caltech. He makes the argument that there are a lot less recoverable fossil fuels than assumed by just about everyone, including the IPCC emissions scenarios. His conclusion is that even if we burn all the fossil fuels on the planet, atmospheric carbon dioxide will not exceed 500 ppm.

Is he right?  Perhaps, although his analysis considers only conventional fossil fuels and does not take into account unconventional oil sources like tar sands or shale. He also does not consider carbon cycle feedbacks that could also add carbon dioxide to the atmosphere.

If true, it's undoubtedly good news for the climate but potentially bad news for our society, since it means that we will be seeing the price of energy inexorably rising in the future as competition for remaining energy resources becomes more fierce.

My sense is that, while we can quibble about the numbers, it does seem likely that the IPCC emissions scenarios have overestimated recoverable coal reserves. This suggests that, at the very least, the highest emissions scenarios may be physically impossible to realize.

These criminals are slippery — very slippery

The Christian Science Monitor notices a rash of slippery thieves making off with the newest hot commodity: grease.

The newsweekly uncorks a whopper in defense of crop-based fuels

The massive biofuel mandate embedded in the 2007 Energy Act, signed amid much bipartisan hoopla, is coming under heavy fire. The Wall Street Journal reported recently that two dozen Republican senators have formally asked the EPA to lower the mandate in response to heightened food prices (a power granted to the agency in the Energy […]

Good sign

China vows to “actively join” post-Kyoto climate talks.

Tropical insects under grave threat from climate change, study says

Tropical insects and other temperature-dependent critters that make their home in the tropics could be in grave danger from climate change, according to a new study published in the Proceedings of the National Academy of Sciences. As opposed to species at the world’s poles that frequently encounter a wide range of temperatures, tropical insects and […]

Greenpeace report calls carbon capture and sequestration ‘false hope’

On Monday, Greenpeace released a new report called "False Hope: Why carbon capture and storage won’t save the climate." Here are the conclusions, as summarized by Ken Ward Jr.: • Adequate technology is not expected to be commercially available until 2030, while leading climate experts say carbon dioxide emissions need to level off by 2015 […]

Myanmar cyclone is a portent of disasters to come

At least 10,000 people lost their lives when a tropical cyclone struck the nation of Myanmar, in Southeast Asia. Perhaps the jury is still out on the extent to which storm intensity can be related to climate change. What is clear is that sea-level rise will make future storms, more intense or no, much more […]

Monday bummer blogging

Damn, one of the more promising ideas, biochar, seems to be a little less promising than hoped:

... a new study ... suggests that these supposed benefits of biochar may be somewhat overstated.

... They found that when charcoal was mixed into humus ... charcoal caused greatly increased losses of native soil organic matter, and soil carbon ... Much of this lost soil carbon would be released as carbon dioxide, a greenhouse gas. Therefore, while it is true that charcoal represents a long term sink of carbon because of its persistence, this effect is at least partially offset by the capacity of charcoal to greatly promote the loss of that carbon already present in the soil.

Oh, and you know that thing Al Gore talked about, where birds would emerge from their eggs only to find that their usual food had already peaked and declined because the changing climate had disconnected formerly co-evolved species? Well, caribou go next:

The longer we wait to move away from gasoline, the more high gas prices will hurt

Like Americans, Europeans are generally not fond of rising fuel costs. Unlike Americans, they’re much better at handling them. It isn’t difficult to understand why; they simply planned ahead. Geoffrey Styles writes: A big part of our problem is that most Americans are still driving cars that were purchased when gasoline was under $1.50/gal., to […]
