A solar grand plan

A roadmap to getting 70 percent of U.S. electricity from solar by 2050

OK, having spent an absurd amount of time bashing on a crappy article that came out while I was on vacation, let me turn my attention to an extraordinarily good one (via HillHeat): "A Solar Grand Plan," by Ken Zweibel (NREL), James Mason (Solar Energy Campaign), and Vasilis Fthenakis (Brookhaven National Photovoltaic Environmental, Health and Safety Research Center). Some flaw in my character leaves me much less able to analyze things I like, so mostly I’ll just urge you to go read it. Here are the nut concepts, though, via the Scientific American editors: • A massive switch from coal, …

Reclusive candy billionaire opposes drilling near his Montana land

Ranchers and conservationists fighting to keep drills out of coal and gas deposits along Montana’s Tongue River are finding an ally in landowner and reclusive billionaire Forrest E. Mars Jr., former CEO of the Mars candy company. Sweet.

What does California's climate bill mandate?

Does AB 32 call for maximizing emission reductions or minimizing costs?

California’s pioneering climate legislation, the Global Warming Solutions Act, or AB 32, caps the state’s emissions at 1990 levels by 2020. That’s the headline, anyway. But the bill contains other interesting statutory language. For one thing, 1990-levels-by-2020 is referred throughout the bill as a limit, not a target. The implication would seem to be that it’s a floor on emissions reductions, not a ceiling. What’s more, Sec. 38560 says this (my emphasis): The state board shall adopt rules and regulations in an open public process to achieve the maximum technologically feasible and cost-effective greenhouse gas emission reductions from sources or …

Taking Germany 100 percent renewable

German scientists develop Combined Power Plant

Via the The Sietch blog, some very, very cool stuff out of the University of Kassel in Germany — the Combined Power Plant: The secure and constant provision of power anywhere and at anytime by renewable energies is now made possible thanks to the Combined Power Plant. The Combined Power Plant links and controls 36 wind, solar, biomass and hydropower installations spread throughout Germany. It is just as reliable and powerful as a conventional large-scale power station. The Combined Renewable Energy Power Plant shows how, through joint control of small and decentralised plants, it is possible to provide reliable electricity …

Hansen v. coal

PRE-PUBLISHING UPDATE: After I wrote this but before I posted it, I got an email from Grist reader CD notifying me of the sad news that Mass.’s gov approved the coal gasification plant. Decisions like this are going to look awfully stupid in a few years. —– I meant to mention this last week, but better late than never: Kudos to climate scientist James Hansen, not only for being a public advocate against coal, but doing so in a targeted op-ed in the Boston Globe, geared to two decisions that the citizens of Mass. will be making soon. Hansen has …

Kiwis say jets are 10 percent of NZ's climate impact, not 2-3 percent

Tourism and carbon neutrality

This story is critical -- another datum showing that the global jet travel binge is both global suicide and homicide all at once, complete with pre-flight thuggery from the TSA* and a side dish of helping-promote-coal-to-liquids on the side (there was another story today about the U.S. (Ch)Air Force's new plan for dealing with peak oil: burn liquified coal / natural gas mixtures).

Get real, deniers!

Climate skeptics claim no warming since 1998

Honestly, if anyone tells you "For nearly a decade now, there has been no global warming" -- as this Boston Globe columnist has -- they simply are not interested in seriously trying to understand and deal with the gravest problem facing humanity. They deserve the label "global warming denier" for willfully trying to confuse the public debate. Let's look at the data, from NASA, presented last month (PDF): Through the first 11 months, 2007 is the second warmest year in the period of instrumental data, behind the record warmth of 2005, in the Goddard Institute for Space Studies (GISS) analysis. The unusual warmth in 2007 is noteworthy because it occurs at a time when solar irradiance is at a minimum and the equatorial Pacific Ocean has entered the cool phase of its natural El Niño -- La Niña cycle. Yes, in some global datasets -- not NASA's, however -- 1998 is still the peak year because that year we had global warming plus the warm phase of the natural El Niño-La Niña cycle. But guess what, deniers? Climate change is about a change in the "climate." A single year doesn't make the climate, that's why people use a running average -- in order to show the trend. Duh! NASA points out:

The 'Inhofe 400' Skeptic of the Day

Today: Christopher Castro

In previous editions of the "Inhofe 400," we found one skeptic whose only qualification for being a "climate expert" was to have written an op-ed and another who argues that climate change must not be happening because God would never allow it. We also found some economists who don't seem to doubt that humans are causing the climate to change. Today's "skeptic," Prof. Christopher L. Castro, is a bonafide atmospheric scientist, so he clearly has relevant expertise on his resume. I emailed Prof. Castro about being on this list, and he replied: Since I'm asked about this often, my "official" position on global warming is given in my series of lectures I present in NATS 101 (accessible via my website link). You are free to quote my position from that if you like. I went on his website and found these quotes from this lecture (MS PowerPoint file, slides 3 and 4):

Canada should consider adopting carbon tax, says panel

Canada should strongly consider adopting a carbon tax along with an emissions cap-and-trade system, a panel of experts advised the government today. The panel had been asked for advice on how Canada could meet its goal of reducing emissions by 45 to 65 percent of 2003 levels by 2050. Environment Minister John Baird put the kibosh on a country-wide carbon tax last year, but the province of Quebec has implemented one and appears to be doing très bien, merci.
