Global average temperature 1850 – 2018

    Who measured what temperatures where over that period? Meaningless data.

      It’s a version of the data compiled by NASA’s Goddard Institute for Space Studies.

    It would be interesting to superimpose the build up of CO2 in the atmosphere over the same period. I suspect there will be a strong similarity between the two curves.

      Of course. We have known for about 200 years that carbon-dioxide could produce a greenhouse effect and have been capable of accurately calculating the scale of the effect for over a century. We know that there is a causal link between concentration of carbon-dioxide partial pressure and the greenhouse effect. This is because carbon-dioxide is transparent to UK and visible light from the sun but absorbs infrared light emitted as heat from the earth’s surface.

        There is of course a correlation between average surface temperature and greenhouse gases, however the relationship is interactive – replete with feedback mechanisms. That is, increased temperatures at the earth’s surface (including the oceans) will release more greenhouse gases to the atmosphere than would otherwise be the case. This is one complication that makes it difficult to make a definitive statement about a causal relationship.

        Yes and that is positive feedback, a condition that is inherently unstable.

        There is traceable, human-sourced CO2 causing oceanic acidification. 2014 Columbia University summary: https://phys.org/news/2014-11-global-human-caused-ocean-acidification.html

    Did the editor upload this graph merely to stress the notion that disputes about political economics may whet the brain, but in effect are just as useful as the proverbal rearranging of deck chairs on the Titanic? I admit he does have a point.

    More meaningless data…. I’d laugh out loud but it’s for real…

    Thanks Mike Ryan for linking to a description of the wide range of data supporting human-caused global warming – as in Ten Indicators of a Warming World.

    Helge Nome and other sceptics – so a superficial assessment of one kind of data by a non-expert outweighs all the work of thousands of scientists?

    Did you think they never thought of all the little excuses you come up with to avoid the uncomfortable conclusion?

    A simple truth is that warming is proceeding pretty much as predicted thirty years ago, or perhaps a bit faster.

    Let’s not forget the unpredictable effects of multiple interacting environmental feedback loops. In early 2005, before Gore’s “An Inconvenient Truth” I predicted unpredictably nonlinear acceleration of increasingly radical thermodynamic & hydrodynamic dysequilibria, globally.

    My unheeded (and published) prediction was proven correct within 6 years, as accelerating glacial melting and movement exceeded all prior official predictions by nearly an order of magnitude.

    Anyway, we should also consider the insanity of current crypto-coin mining & the illogic architecture & basic concepts. If alt.coin mining continues at the rate recently au current, analysts predict that it could raise the global average temperature by an extra 2*C (degrees Celsius). We should also remember that nearly 70% of us live within coastal disaster zones that will become much more dangerous much more rapidly than predicted.

    Thus, I predict that global failure to embrace sane, truly appropriate emergency measures NOW will doom us to self-extinction and MELE much sooner than any current models predict.

    Nick – I agree, 100%. If you haven’t read it yet, you may enjoy Ralph Metzner’s “Green Psychology” – wherein he points out that, as in the HMS Titanic, all us lower-class passengers (the losing class 99% of us) are locked into the lower decks, while the winning-class kleptocrats eat, drink, dance and play musical deck chairs as the Titanic ship of state goes down (and drags everything else along with it). Thus, Chomsky’s warnings about potential omnicide, though I think “ecocide” is more precise. After all, the real bottom of the food chain exists very deep in the Earth’s crust (seemingly solid rock) and around volcanic vent environments (without light, etc.) at the floor of the oceans and in their deepest depths.

    However, unlike Metzner, I realize that the locks are illusory and that us 99%ers are the ones who keep us locked in and, possibly, doomed. It is no help to blame the winning-class for brainwashing us into am idiocracy disguised as hypnocracy masquerading as kleptocracy posing as plutocracy pretending to be republican democracy for a free world. It takes the vast majority of us to keep the game going as is.

    Yet, changing the rules, the goal and the purpose of the world game is no more difficult than changing the rules, the goal and purpose of a card game, or changing the script and ending of an unfinished screenplay.

    PS: As most well-informed observers know, methane release threatens much more lethal effects, nearly 22 times more potent than CO2. The CO2 level increase accelerates sequestered methane release that can accelerate at an unstoppably exponential rate.
    Ho hum, right? Oh, well… Hi Ho!

      The real answer lies in the absorption spectra of CO2 and methane and the emission spectra of the earth.

    And please let us not forget the new “Silk Road” that is being built in Asia and who is financing it and against whom. And all the floods, and almost daily fires and climatic disasters that have engulfed the world and are now so commonplace that most people just turn a blind eye and walk by.

    The denouement of Sapiens and most other forms of life on earth is near. Since 1900, over 500 species of animals have gone extinct. Since the beginning of the industrial revolution and capitalism 400 years-ago, more than 650 plant species and more than 480 animals have gone extinct. More are added to the endangered species list on a regular basis. Over 3000 animals and more than 2600 plants are currently considered endangered. Sapiens survived for over 200,000 years through imagination and creativity. And by being unable or choosing not to interfere too much in the nonhuman actions and events that sustain it. Today these seem to be failing Sapiens, as they lead to faulty understandings and no solutions to these problems. When Sapiens dies and takes most of the other life on earth with it, all the blame belongs to Sapiens, the now most powerful species on earth.
