    Actually, the Carbon Atlas (linked from the linked article) is pretty neat. Nice to be able to investigate the output data from the climate models in an easy way.

    The S&L Crisis did not strike until the early 1980s.

    Some other causes need to be found for the downturn in the second half of the 1970s. This is important because the graph indicates that the downturn was large.

    Might I suggest the Great Recession of 1975 and the Opec Oil Shock MkII?

    The fourth climate change thread in as many days – have you asked Mark if you could rename his blog to Climate Clippings?

    Slight matter of pedantry – graph 1 is not strictly showing how atmospheric carbon dioxide concentration is rising over time, but how much carbon dioxide humans are emitting over time.

    There is a subtle difference…

    The last graph at RenewEconomy’s Graph of the Day: Nine simple charts to explain the global carbon budget, from page 20 of Carbon Budget 2013, is the most concerning. It shows the world to be following the Representative Concentration Pathway 8.5 scenario, which results in a 3.2 to 5.4°C by 2100 (the plateau is later…).

    2 – 3°C is probably sufficient to ensure that a cohesive global human society is not in existence by 2100, and anything over 3°C is probably setting most of humanity for a world that resembles the more troubles parts of Africa as it is now, in terms of political and environmental problems.

    Makes me glad that my plan is not to be living on this planet by 2050. Pity the poor suckers that are.

    We’re not going to fix it. If we’re lucky 20 or 30 years from now someone will find a technological fix. Until then, we’re just going to bumble along achieving nothing. The only option left is to sit back and watch it all sliding out of control…

    Just to help people get some context on the RCP scenarios, open in a new tab the emissions graph from RenewEconomy and in another tab the warming that follows the same emissions scenarios. Toggle between the two, taking care to remember that the colours used to represent the different scenarios are not always the same for both graphs.

    Note too that RCP8.5 temperature is barely shifting from a linearly increasing trajectory by 2100, let alone reaching a plateau. And keep in mind that a 4°C warmer world, let alone a 6°C warmer one, is incompatible with the survival of human society in any way that we know it.

    Lovely November rain falling on this little spot on the Dorrigo Plateau.I heard on radio this week a connection between high bushfire temperatures and off Indian ocean variabilities,by the CSIRO.It would seem that in Victorian events of catastrophe and drama,the regularity of cycles is still playing their role than mere CO2 emissions.I came across an article in Scientific American of depositing CO2 in hot brine underground,and then reusing it again on the surface.A Thorium option as a nuke site in December’s Silicon Chip Magazine is now in action as a website.Not completely happy with either,but at least the boring arguments are slowly being now converted to,perhaps a few new directions! Not always happy with either magazines articles etc. support magazines they do not clog up the paperless office!

    Absolutely nothing will change until nukes, most likely Thorium ( LFTR) are a big part of the mix

    If you want to feel a little bit optimistic:
    More and more people are linking natural disasters to climate warming. Aus Tea party ministers are starting to sound hysterical when they deny that the latest disaster was caused by global warming.
    Investment in the fossil fuel industry is looking more and more risky. The 30 mt/yr Wandoan mine was cancelled.
    Coal fired power stations are shutting down and winding back.
    Fossil power generators are complaining that the growth of renewables is pushing the price they receive down.
    Queenslanders are still investing in rooftop solar despite the FIT dropping to 8 cents/kWh.
    The world is in a chronic economic recession. A war against global warming is one of the most logical ways of ending this recession.

    I noted from the NSW 7.30 Report that this weekend marks the start of wholesale demolition and clearing of Winmallee Blue Mountains bushfire destroyed homes….except that some insurers have refused to bankroll this re-build phase leaving the NSW Government to try and fill the void. Couple that with huge increases in flood and cyclone insurance damage from recent Queensland ‘events’ which may have all sorts of implications for Abbott’s ‘populate and develop the north’ drive (white paper coming).
    This could be the achilles heel of the Federal Government’s direct action plan on climate change. When the economy and the business world feel the impact of public frustration over huge cost increases, Abbott will get the message. Was it Harold McMillan who warned of the most difficult threat once in power…”events dear boy, events”.
    Two months in power has shown Abbott unable to deal.

    Onthe matter of the progression of human-caused warming, Australia’s Peter Christoff is not exactly optimistic:


    Christoff’s comments are measured and informed, and his observations on the effect of late action should have any genuine leader sitting up in his or her seat.

    In light of these comments I cannot believe the obstinate idiocy of the Coalition, who are willing to destroy their grandchildren’s world for whatever passes as thought in their minds. And they can’t ever say that they weren’t told, because we’re telling them over and over and over again.

  14. Bernard J.

    Further to my post at # 15 yesterday about Peter Christoff, Matthew England also talks about “Four Degrees of Global Warming: Australia in a Hot World” and about the consequences of the warming that are in train… and about which we’re currently not only not doing anything, but about which the Coalition government is actively seeking to avoid any genuine action at all:


    Listen and weep for your children and grandchildren.

    And the weight of science pushing against denialism of the need to act against human-caused climate change grows:


    As I noted at HotWhopper, I’m going to forward this paper to federal politicians, along with a letter posing a number of direct questions intended to ascertain that they have read the paper, and that they understand the significance of the paper, and what are their intended responses to the paper.

    I’d suggest that others might think about doing the same, and sharing any responses they receive.
