Climate Climate & Energy

  • It’s also the road to ‘energy security’

    A few times now John has made a point I have made in the past and now shall make again (how's that for a self-referential intro?). To wit:

    "Energy security" is a lopsided way of framing our energy problem, and left un-balanced, will do more harm than good.

    Why? Because the shortest, cheapest route to energy security (or "independence," if you like) is through coal, and coal is ... wait for it ... the enemy of the human race. This is not just true for China and the U.S.; Germany, Britain, and even France are planning a slew of new coal plants.

    For more on this crucial point, see this fantastic post from Jerome a Paris.

  • An interview with Travis Bradford, author of Solar Revolution

    Solar power has been the Next Big Thing for decades now, yet it remains a niche player in the energy world. The problem of intermittency is unsolved, up-front capital costs remain high, and surging demand for polysilicon, a key component of solar panels, has recently outstripped supply, stifling production. Travis Bradford. So when someone claims […]

  • Know it

    There's a great op-ed in the NYT today making the argument that, however much Malthus and his heirs have fallen out of favor, they may have the last laugh. Limits are back, baby!

    Here are two memes I'm happy to see getting out into the mainstream:

    1. In the words of a recent interviewee (watch for it tomorrow): Coal is the enemy of the human race.
    2. This, from the last paragraph:
      ... we really need to start thinking hard about how our societies -- especially those that are already very rich -- can maintain their social and political stability, and satisfy the aspirations of their citizens, when we can no longer count on endless economic growth.
      Yup.

  • One way or the other, we’re waiting for the next administration

    If the Supreme Court rules that CO2 does not have to be regulated, it will give the present administration cover to do nothing for two more years. However, most serious candidates for president support action to curb greenhouse-gas emissions, so regardless, I suspect you'll see action in the next administration.

    If the Supreme Court rules that CO2 can be regulated, the administration will ... do nothing for two more years. But again, the next president will likely take some action.

    If the Supreme Court rules that CO2 must be regulated, the administration will drag its feet and ... end up doing nothing for two more years. But again, the next president will likely take some action.

    Thus, regardless of what the court rules, we will have to wait for '09 to see any action on emissions reductions -- but we'll see action then regardless of what the court rules.

  • It’s likely not the primary cause

    In climate change debates, one hears a lot about the Sun. A favorite argument of those opposed to action is that the warming we're presently experiencing is due to increases in solar output, also known as solar brightening, and not from greenhouse gases.

    Before critiquing this argument, first remember what the IPCC says about human contribution to climate change:

    There is new and stronger evidence that most of the warming observed over the last 50 years is attributable to human activities.

    Note that the IPCC says most of the recent warming is due to human activities. This leaves as much as 50% of the recent warming not attributed to humans.

    It is certainly possible -- and fully consistent with the IPCC -- for solar to have contributed some part of the warming we are experiencing.

    The real question is whether solar brightening could be the dominant cause of the recent warming, with humans playing a minor role. That is unlikely, for the following reasons:

  • ‘They predicted global cooling in the 70s’–But that didn’t even remotely resemble today’s consensus

    (Part of the How to Talk to a Global Warming Skeptic guide)

    Objection: The alarmists were predicting the onset of an ice age in the '70s. Now it's too much warming! Why should we believe them this time?

    Answer: It is true that there were some predictions of an "imminent ice age" in the 1970s, but a cursory comparison of those warnings and today's reveals a huge difference.

  • Understanding what is happening right under our noses does not require paleoclimate perfection

    (Part of the How to Talk to a Global Warming Skeptic guide)

    Objection: Climate science can't even fully explain why the climate did what it did in the past. How can they claim to know what is going on today?

    Answer: There are two requirements for understanding what happened at a particular point of climate change in geological history. One is an internally consistent theory based on physical principles; the other is sufficient data to determine the physical properties involved.

  • Report spells out high economic costs of climate chaos

    Peter Madden, chief executive of Forum for the Future, writes a monthly column for Gristmill on sustainability in the U.K. and Europe.

    While the U.S. was absorbed in the midterm elections, a major report on the economics of climate change was launched in the U.K. The weighty "Stern Review" -- 700 pages in all -- was the work of Sir Nicholas Stern, ex-chief economist at the World Bank. Produced at the behest of the chancellor, Gordon Brown, it has had a profound impact on political and business attitudes in this country.

    This is not surprising when the headline message of the report is that climate change could shrink the global economy by a fifth, equivalent to the Great Depression of the 1930s.

    Stern's analysis shows that taking action now will cost an average of 1 percent of global GDP a year over the coming decades, whilst not acting will cost between 5 and 20 percent of GDP a year over the same time frame.

  • The line-up of legal issues

    Lawyers and Supreme Court commentators hardly seem the type to camp out for tickets. But that's precisely what a line of expectant court-watchers will be doing one week from today -- braving early morning Capitol Hill in hopes of gaining entrance to oral argument in Massachusetts v. EPA.

    Like a pre-game sportscast, today's post will attempt to give a flavor for points of contention -- in this case, the legal issues before the court. It won't be exhaustive. If you're looking for greater detail, refer to either the briefs or to this recent report (PDF).

    The case involves a suit by Massachusetts and its allies (a coalition of other states and nonprofit groups) -- I'll refer to them as the petitioners -- against the EPA for refusing to use the Clean Air Act to regulate greenhouse gases, including carbon dioxide emitted from motor vehicles. The petitioners lost (PDF) in the U.S. Court of Appeals for the D.C. Circuit, but convinced the U.S. Supreme Court to review the case.

    When the Supreme Court decides to hear a case, it grants certiorari on specific questions. In Massachusetts v. EPA, the Court agreed to consider two:

  • ‘Chaotic systems are not predictable’–Sure, but who says climate is chaotic?

    (Part of the How to Talk to a Global Warming Skeptic guide)

    Objection: Climate is an inherently chaotic system, and as such its behavior can not be predicted.

    Answer: Firstly, let's make sure we define climate: an average of weather patterns over some meaningful time period. We may thus discount the chaotic annual fluctuations of global mean temperature. That's weather, and one or two anomalous years does not represent a climate shift.

    Quite a few people believe that climate is a chaotic system, and maybe on some large-scale level it is. But it is not chaotic on anything approaching the time scales of which humans need to be mindful.
