A new piece of conventional wisdom is rapidly congealing among mainstream pundits: global warming is happening, but there's nothing we can do about it. Might as well just batten down the hatches and hope for the best.
You'll hear the same basic message from Fareed Zakaria, Washington Post columnist Robert Samuelson, Newsweek columnist George Will, and a number of other mandarins of center-right establishment opinion.
Let's be clear: This proto-conventional wisdom is wrong. There's plenty we can do about global warming.
What would it mean to do something serious about climate change? Scientists tell us that to stabilize atmospheric greenhouse gases at between 450 and 550 parts per million CO2 equivalent -- a level sufficient to avoid unstoppable, irreversible changes -- we'll need to reduce global GHG emissions by around 80% by 2050. (Obviously all these figures are approximations, and could move up or down with future study.)
That sounds like a huge task, and if you're trapped in a bubble of conventional thinking, you'll likely throw your hands up in despair. But there are several plans and programs on the table that claim to be able to meet that goal -- without sparking a global economic recession, and without relying on coal or nuclear power.
Energy [R]evolution is a report developed by Greenpeace and the European Renewable Energy Council (EREC) "in conjunction with specialists from the Institute of Technical Thermodynamics at the German Aerospace Centre (DLR) and more than 30 scientists and engineers from universities, institutes and the renewable energy industry around the world." Here's the summary:
Renewable energy, combined with efficiencies from the 'smart use' of energy, can deliver half of the world's energy needs by 2050, according to one of the most comprehensive plans for future sustainable energy provision, launched today. The report ... provides a practical blueprint for how to cut global CO2 emissions by almost 50% within the next 43 years, whilst providing a secure and affordable energy supply and, critically, maintaining steady worldwide economic development. Notably, the plan takes into account rapid economic growth areas such as China, India and Africa, and highlights the economic advantages of the energy revolution scenario. It concludes that renewable energies will represent the backbone of the world's economy -- not only in OECD countries, but also in developing countries such as China, India and Brazil. "Renewable Energy will deliver nearly 70% of global electricity supply and 65% of global heat supply by 2050."Another hopeful report is called "Tackling Climate Change in the U.S.: Potential U.S. Carbon Emissions Reductions from Renewable Energy and Energy Efficiency by 2030." It all started when ...
... a year-and-a-half ago the American Solar Energy Society recruited a team of volunteer energy experts. We did not give them any targets to aim for. We merely asked them to estimate how much their technologies could reduce carbon emissions by the year 2030 if they were deployed as part of a highly aggressive national effort to combat global warming. The experts produced a series of nine papers. Three of them examined the potential carbon emissions reductions from energy efficiency opportunities in buildings, transportation, and industry. The other six covered renewable energy technologies: biofuels in the form of cellulosic ethanol to replace gasoline, and electric power production from wind, concentrating solar, roof-mounted photovoltaics, biomass, and geothermal. The 200-page report being released today -- Tackling Climate Change in the U.S. -- is the culmination of this effort. The results show that we have a variety of promising means available to battle global warming. They indicate that energy efficiency measures can prevent our carbon emissions from growing over the next 23 years, even as our economy grows. The six renewable technologies have the potential to make the kind of deep cuts needed in our carbon emissions. Of the total carbon reductions possible, 57% are due to energy efficiency and 43% are from renewables.The Sierra Club has adopted this plan as its official energy strategy.
On the legislative side, Sen. Bernie Sanders' Global Warming Pollution Reduction Act claims it will reduce U.S. GHG emissions 80% from 1990 levels by 2050. In the House, Henry Waxman's Safe Climate Act does roughly the same.
In other heartening news, an extensive piece in the Wall Street Journal details how costs are falling for clean energy and soon will be competitive with dirty energy. Imagine what could be done on the clean energy front if instead of spending $1.2 billion a year on renewable energy research, the feds borrowed, say, $50 billion from the defense budget. Imagine if America mobilized with the same zeal and unity of purpose it's brought to previous challenges.
None of this settles the argument of whether aggressive emissions targets are reachable in a way that won't hurt the economy. I think it's possible; others disagree.
The point is just that we don't have to accept the casual, unthinking fatalism Beltway "centrists" are currently trying to urge on us. It's far, far from a settled question.
<Hybrid autos save money in long run | Global warming: How it's playing in Cleveland> |
offshore wind tooOffshore wind power wasn't included in the Tackling Climate Change report because the authors decided the technology wasn't "mature." I don't know if this was already reported in Gristmill, but a University of Delaware study found there was enough wind energy potential off the Atlantic seaboard to supply the region's entire energy demand. The wind resource off the Mid-Atlantic coast could supply the energy needs of nine states from Massachusetts to North Carolina, plus the District of Columbia--with enough left over to support a 50 percent increase in future energy demand... Wind resources in the waters of the Great Lakes are also extremely good. |

You can not do anything until>> There's plenty we can do about global warming.>>> LOL, you guys make me puke. You can not, and should not do anything until y'all know what you are talking about. So far on this site, and so many others, y'all are sheep following some delusion created by Big Oil with the help of client scientists. STOP, and look squarely at the science and the observations. Then instead of praying to the heavens, start examining the sea.

Samuelson disregards reality ...and yet he keeps his page access at Newsweek, Washington Post, et al. As I wrote in J'accuse! Distorting reality in "Global Warming's Real Inconvenient Truth", a piece discussing one of Samuelson's pieces last summer, Samuelson's "Global Warming's Real Inconvenient Truth" has factual errors, misleading statements and conclusions, and provides a counterproductive path for thinking about and achieving change for a better future. ... And, we all need to remember -- there is no magical silver bullet. I agree with Samuelson that we must have a much stronger R&D program in energy issues. I am in violent disagreement, however, that we should simply sit on our hands, watching the world decay around us, placing at risk the entire concept of a future for ourselves and future generations, with a blind hope that those research investments will come up with that non-existent silver bullet that will magically restore the world to pre-industrial age carbon dioxide levels and will bring back to life all the species that became extinct in the interim. Robert J. Samuelson: J'accuse! You are using your pulpit to mislead and deceive. You seek to perpetuate the problem rather than solve it. The Washington Post is Romancing the Skeptics. Its editorials, recently, are strong re Global Warming and the need for action. The reporters, in stories, all too often show an ignorance, quoted meteorologists telling us why GW is just natural phenomena, and they strive to balance their OPEDs and LTEs. I had a LTE attacked Skeptics one Saturday, responding to a skeptics letter the week before. Soon afterwards, I open the letters section to see a BS LTE from the Competitive Enterprise Institute (CEI) attacking Gore. AHHH!!!! |
The Will pieceDeserves a full fledged assault Dave. If you start it up, I think we will all join in. Or I will later here and on my blog. Gotta go for now. http://amazngdrx.blogharbor.com/blog |
I second caniscandida; Fareed is okZakaria does not deserve to be lumped in with Will and Samuelson. I urge everyone to read his column and judge for yourself. I agree with Dave that there is plenty we can do to prevent catastrophic climate change, and the two reports he mentions are examples of the potential out there. We need to adopt policies at all levels of government that get us on this track asap. But we are already experiencing climate change impacts and will do so regardless of changes to our energy policy so we can't ignore preparations for those impacts. Besides much of what we should do to increase are preparedness has other environmental benefits, like restoring wetlands in coastal areas, limiting further development in the coast, better preparing for the inevitable droughts especially in the west and midwest, etc. As with most things there is potential to use adaptation as an excuse for inaction or to build things that actually make things worse, like some levees I can think of on the Gulf Coast. But if you couple preparedness with a strong program to reduce emissions, I think you can avoid that. Sens. Kerry and Snowe have included language in their recently introduced global warming bill (S. 485) that would help communities assess their climate change vulnerabilities and better prepare for them. The major part of the bill is a cap and trade program, but by including some impact assessment in their bill they have struck a good balance. Our major effort certainly needs to be intransforming our energy system, but we can't ignore preparation for impacts, especially when they have other environmental benefits as well. As Zakaria says in his final sentences: "Mitigation and adaptation complement each other. In both cases, the crucial need is to stop talking and start acting." |
Estimates of low sparks from high-bladed minesLaurence Aurbach write: Where did you come up with a 10% capacity factor for wind turbines? I made an educated guess, based on the high-maintenance experiences of other offshore wind-mining ventures...en.wikipedia.org/wiki/Horns_Rev ...and also the fact that any power produced would be taxed directly by undersea transmission, and indirectly by the need to continuously draw power from the grid to service the mining machinery (thus reducing that mining-machinery's net power contribution to the grid). Large wind turbines require a large amount of energy to operate. Other electricity plants generally use their own electricity, and the difference between the amount they generate and the amount delivered to the grid is readily determined. Wind plants, however, use electricity from the grid, which does not appear to be accounted for in their output figures.[...]It may be that each turbine consumes more than 50% of its rated capacity in its own operation.[...]Whatever the actual amount of consumption, it could seriously diminish any claim of providing a significant amount of energy. |

Apocalypse>> inevitable climate change >>>> Yes it is inevitable now...Don't worry, the seas will not rise much, soon they will fall. Your country will become dry as a bone and... You thought sun tans were in, but soon ice blocks will be the rage. and when industry has ground to a halt, the whole world will turn a whiter shade of pale..... but hey no one will be there to see such beauty. and you though greenhouse gases were the bogeyman, think again Oil is the horseman of the Apocalypse |

Why wind-mining-machinery is inherently lossySam Wells wrote: I'm not sure that such parasitic losses at wind turbine farms are such a big deal, since almost all electrical power generation requires power to make more power. Wind-mining is especially susceptible to costs of all kinds since wind energy is especially diffuse.. phyast.pitt.edu/~blc/book/chapter14.html since winds are driven by forces generated by the sun's heat, wind power is often classified as solar energy[...]the energy in sunlight is spread so diffusely that we must collect it from large areas with correspondingly large collectors in order to obtain appreciable amounts of power. |
Zakaria, oh yeshe was the one the Pentagon consulted on how to sell the Iraqi invasion to the public. A fine piece of work. |
Capacity factorOn dealing with the "capacity factor" talking point. This is a widely used talking point against wind power. The way to deal with it is to compare kwh produced instead of capacity factors. There is a convenient graph on the GE wind power site that provides the necessary data. http://www.gepower.com/prod_serv/products/wind_turbines/e ... It's the "Average energy yield: 3.6 mw" graph. Find the average windspeed for the area. For example 8.5 m/s on an offshore platform in the gulf. That would correspond to 12 million kwh for this 3.6 mw machine. A 1.37 mw generator operating continuously for one year (8760 hours) would produce 12 million kwh. A source that runs for 80% of the time, like a coal or nuclear plant (they have downtime for maintenance), would have to be somewhat larger, 1.71 mw. So to equal the annual kwh output of a standard 1000 mw coal or nuclear plant would take 585 of these 3.6 mw GE machines mounted on the offshore platforms. 1000 wind machines of this size would equal the output of 1700 mw of coal or nuclear generating capacity. To get to the 3000 mw generating capacity that was mentioned in Laurence's link would take slightly larger wind machines than the 3.6 mw GE model. The blade diameter would need to go from the 104 meters of the 3.6 mw model to around 136 meters. Not that diificult a task given mass production and installation. Increasing the scale of the wind machines to around 312 meters would increase the power output to equal 25,000 mw of coal or nuclear generating capacity. Adding wave power could double that output. Electric power equivalent to 50 nuclear reactors or coal plants from 1000 offshore wind/wave power installations. It's sci-fi now, but it doesn't have to remain so. Communications satelites were sci-fi a few decades back too. Hurricane protection can be obtained by mounting the wind/wave power installations on floating platforms that are submersible during severe storm conditions. The whole electric generating capacity of the US is around 1 million mw. That would take 20,000 wind/wave power systems of the 312 meter scale. With conservation saving 40% of current power use, plugin vehicles could be supplied as well, with that same generating capacity. A mix of offshore wind/wave power, say 5000 installations, and large scale wind on the great plains, say 10,000 units, biogas generation from manure,waste, and garbage used in fuel cell/turbines, and solar cogeneration on every suitable roof space and over parking lots, and natural gas from coal and tar sand reserves used in the same fuel cell/turbines as the fossil fuel emergency backup of last resort. I think it's becoming clear that this really is a practical way to go.http://amazngdrx.blogharbor.com/blog |
Adaptation nonsenseDave Roberts writes In today's political reality, focusing on adaptation is in keeping with the essential conservative message: we've got ours, screw everybody else. So lets see if I have this straight: Those of us calling for rich countries to invest more money in adaptation are in fact contributing to the political agenda of those who say "screw everybody else"? Right, that makes sense. It seems to me that Dave Roberts and his conservative straightmen are the ones who agree that we should not be investing in adaptation. So are you implying that those people in developing countries who are calling for more attention to adaptation (you know, because their children are dying and stuff like that) are in fact supporting US conservatives? How narrow minded of them! Don't they even think about our domestic political squabbles before speaking out? Dave Roberts writes: does anyone think the world's developing countries are going to get aid sufficient to allow them to prepare?Pretty ironic in a post about defeatism. They surely won't get any aid with defeatists simply giving up on the billions of people around the world who are suffering today. But it is a lost cause anyway, eh, Dave? Lets talk about Republicans instead! ;-) Note: Tongue firmly in cheek in the above, but there is a message too. |

A Lost Cause?http://www.reutershealth.com/archive/2007/02/14/eline/lin ... One billion poor suffer from neglected diseases: WHO Last Updated: 2007-02-14 9:44:10 -0400 (Reuters Health) JAKARTA (Reuters) - One billion people in tropical countries are still suffering from debilitating and disfiguring diseases associated with poverty, but many remain untreated due to official neglect, health officials said on Wednesday. Despite the existence of inexpensive and safe treatment, those who suffer from diseases such as leprosy, elephantiasis and yaws remain untreated due to a lack of resources and political will, said Jai Narain, South East Asia director of communicable diseases at the World Health Organization (WHO). "These tropical diseases have been neglected by policy makers, by the research community and also by the international community," Nairan told a news conference at the start of an international meeting to tackle tropical diseases. I'd suggest that we should be doing more for these folks, but Dave Roberts might then accuse me of giving aid and comfort to the true enemy, which is of course not unconscionable poverty, but U.S. conservatives! ;-) |

I agree, but huh?amazingdrx: I'm all for empowering women, it should be center in any adaptation agenda. But you lost me with this: It's we environmentalists that are killing the poverty stricken by opposing unlimited growth, pollution, use of toxins like DDT, chemical agribizz, nuclear power, unregulated corporate power, genetically engineered crops, and all of your other pet causes? Right? Where in the world do you come up with that nonsense? It seems common practice on this site to argue by completely misrepresenting other people's views . . .

Global Warming Has Been Cancelled by H2-PVGlobal Warming Has Been Cancelled by H2-PV A 25% growth of PV per year, as happened from 1979 through 2000, until Bush crowd took over, projected into the future shows three FREEDOM DAYS. A 19% price decrease every time the installed PV base doubles, as happed from 1979 through 2000, until the Bush crowd took over, shows the price of each FREEDOM DAY. Doubling occurs every 3 years at 25% compounded annual growth.

Other sources are still needed for off-hours power. FREEDOM DAY #2 is the date that the PV doubles and the extra PV goes to storing energy at 50% round trip efficiency or better, like power is now stored in pumped reservoirs at 50% efficiency electricity to electricity round trip. FREEDOM DAY #3 is the date when PV surplus is sufficient to power all electricity and make hydrogen sufficient to fuel all 200,000,000 cars and light trucks in America.

MitigationSomeone above was confused about the distinction I drew between two different types of short-term mitigation that for some reason the "adaptation denialists" don't like to talk about. Let me try again: Things government does to make things worse: A major example is federal policy on highway construction, which allows (and effectively encourages) continued sprawl development by approving "congestion relief" projects that make long-distance car commuting more feasible. Another example is direct fossil fuel subsidies. Relatively cheap, easy mitigation steps that can be taken now: Examples are conversion to CFC bulbs (by coincidence very topical today), efficiency standards for new construction, and an extensive efficiency retrofitting progtam for existing construction (financed by what are known as "efficiency utilities" where the long-term energy savings are used to finance the improvements). Others may or may not find it useful to distinguish between stopping doing bad things and starting doing good things.I am extremely suspicious of the motives of those who discuss policy in terms of long-term adaptation steps while skipping over the low-hanging mitigation fruit. |
Carbon taxI should have listed a carbon tax as one of the major (probably the major if structured properly) short-term mitigation steps. |
Global Warming creates Huge New Product MarketsGlobal warming will require cost effective non-carbon-based fuel for every system-- be it home, transportation, hot tub, etc. in the world. New products, and education for every adult and child worldwide is required-- fast! That's alotta sales! Let's ask world industry take the challenge. For example, there is a compressed air technology for automobiles. Let's see Detroit, China, Germany hop on that opportunity!

Evidence that the technology is hereDavid, have you seen Stephen Pacala and Robert Socolow's paper from Science? In it they demonstrate that the problem can be addressed with at least 15 existing technologies and policy options (called "wedges"). No single wedge can get us where we need to be, but a combination of about seven can. I discuss their paper more in depth in a recent post I did responding to Samuelson's Op-Ed.www.climate411.org |
