  • Climate Change: Celestial Wobbles by Andrea Graves

    From Crash@21:1/5 to All on Tue Mar 21 10:56:25 2023
    This is a reference to an article that appeared in the NZ Listener
    issue for March 18-24. I cannot find this article anywhere online. I
    know that a number of contributors here are skeptical of man-made
    global warming so I am looking for any evidence that refutes what this
    article asserts.

    The article addresses causes of climate change - covering historical
    causes of heating and warming of our planet. Graves identifies that
    the Earths orbit varies because of a number of celestial issues such
    as gravitational pull of various planets including the Sun and
    references the 'Milankovich Cycles.'

    https://en.wikipedia.org/wiki/Milankovitch_cycles

    This identifies how the Earths climate has changed historically and
    attributes this to variations of Earth's orbit around the Sun.

    From here Graves postulates that our current warming cycle is vastly
    faster than previous warming cycles and this is caused by the vastly
    increased levels of CO2 in the atmosphere caused by increased COI2
    levels since the Industrial Revolution:

    The article is fact-checked by Professor Tim Naish (Victoria
    University).

    For me I see climate as being caused by many variables. So you can pick any number of variables as evidence for your arugement.

    The time peiod og 1850 onwards is used to show that since man made CO2 into
    the atmosphere the temp has risen. The point is that the earth was as warm
    as it is today for a long period and the CO2 levels were way down compared
    to today.

    See the graph in

    https://www.stuff.co.nz/environment/climate-news/131533573/latest-ipcc-climate-change-report-the-world-is-changing-rapidly-see-for-yourself

    Under the graph:-

    "This ain't computer modelling, this is what temperature records actually show (and it’s the fastest temperature change we’ve seen since human civilisation
    began)."

    There is agreement that homo spaiens started to move out of South Africa
    some 200,000 years ago. So, I would suggest that they problably measured the temperature by how hot it felt. Thermometers arrived in the 17th century,
    some 400 years ago. Before then we do not know how hot it was. So the ice
    age of 10,000 years ago was just that, ice.






    To get things sorted to a proper concenus of opinion all these pieces have
    to be explained it what their effects are.
