Back To The Future

The National Academy of Sciences asks “When could scientists have first known about climate change?”

National Academy of Sciences on X: “When could scientists have first known about climate change? A thought experiment by #NASmembers Ben Santer, Susan Solomon & Qiang Fu shows the fingerprints appeared early on—demonstrating the power of long-term climate monitoring.

Fifty years ago they answered the question.

“The climates of the earth have always been changing, and they will doubtless continue to do so in the future. How large these future changes will be, and where and how rapidly they will occur, we do not know.”

NATIONAL ACADEMY OF SCIENCES, 1975

    Back then they knew that they don’t know.
    Now they pretend that they do
    though none of their many models can predict the future nor the past(before adjustment).
    Maybe the total failures of their ice age and warming predictions encouraged them to believe that they are supercompetent.

    Climate Science made probably the biggest progress of any science in history.
    They went from no being able to read thermometers a hundred yeare ago
    to predicting an ice age to predict a warming
    to reading climate fingerprints within only a century.

    Meanwhile, back in South Central Minnesota we can’t even hit 85 degrees in the next 10 day forecast. I’m old enough to remember when it occasionally hit 100 in early August. crops have never looked better at this time of year. Viva La climate change!!!

    The ‘members’ (Santer, Solomon & Fu) have moved on from reading tea leaves and chicken entrails to now reading ‘fingerprints’? How sciency!

    Also , they’ve misspelled @sciam: there’s no ‘i’ in SCAM.

    It’s very simple: The climate change that they reckoned could only be first known when they first reckoned it, and the next climate change that they fabricate will only be known when they fabricate it. The basic principle is, scientist can only know that which doesn’t exist when they first declare that it exists.

    Beaking news…. the world is running out of oil, oops. postponed again. BP announces biggest oil discovery for them in the past 25 years. it’s in Brazil. https://lite.cnn.com/2025/08/04/business/bp-oil-gas-discovery-intl. in other breaking news…Robert Mueller of trump Russia collusion Fame, his people have confirmed what we all saw when he testified b 4 Congress…. we saw that he’s brain-addled. he’s now living in a dementia facility. Google it.

      Unfortunately, it’s in Brazil. That will keep the commies in power for decades.

      Only experts (and Robert Muller) would have thought that humanity would run out of worlds
      most abudant liquid after water
      within a few decades?
      The same experts who think that green energy is cheaper and reliable.

    I see a popular News website says that Phoenix Arizona had a high temperature today of 120. weather underground reports that the High temp in Phoenix today was 114. in central Minnesota today I think our high was a scorching 78. apparently 78 is not unhealthy as our local post office was told to not have the AC set cooler than 78…. a number of years ago, to save on the power bill

  7. People join professional institutions because it is required for their accreditation, little more. In my experience, membership is more a substitute for, rather than an indication, of competence. I don’t recall I K Brunel joining the Institution of Mechanical Engineers, nor were the Wright Brothers members of the AIAA. People understand gentleman’s clubs, they are not so hot on actual engineering or science.
