Settled Science

If settled science is an oxymoron,
Science is a wonderful thing and has made tremendous strides in the lifetimes of most of us, but there’s one message which keeps being reinforced: the more you know, the more you realise how limited your understanding really is. Scientific knowledge today is vast in extent, but constantly changing, usually incrementally but occasionally in quantum leaps. Just as one field of study seems essentially complete, new areas open up or, in some cases, the received wisdom is found wanting.
What we think of as knowledge is a hodgepodge of evidence, interpretation and theory. According to Karl Popper, science progresses by testing hypotheses against the evidence. As long as all the evidence is consistent with the hypothesis, this is taken as the current best explanation and may, over time, achieve the status of theory: never 100% proven, but as good an account of the facts as we believe is possible.
AGW is an oxymoron wrapped in a conundrum.
Here is what the scientists found:
# There is no scientific consensus on the human role in climate change.
# Future warming due to human greenhouse gases will likely be much less than IPCC forecasts.
# Carbon dioxide has not caused weather to become more extreme, polar ice and sea ice to melt, or sea level rise to accelerate. These were all false alarms.
# The likely benefits of man-made global warming exceed the likely costs. Here is what this means for public policy:
# Global warming is not a crisis. The threat was exaggerated.
# There is no need to reduce carbon dioxide emissions and no point in attempting to do so.
# It’s time to repeal unnecessary and expensive policies.
# Future policies should aim at fostering economic growth to adapt to natural climate change.
What about those who still say global warming is a crisis?
# The UN’s new report walks back nearly a dozen earlier claims, contains more than a dozen errors, and tries to cover up new discoveries that contradict its earlier claims.
# The Environmental Protection Agency (EPA) relies heavily on the UN’s reports for its finding that carbon dioxide is a pollutant. That finding is now falsified.
# Environmental groups refuse to admit they were wrong. It was never about the science for them.
What about the foods we should eat?  Is that “settled science?”  Ah, not so much.
Today, however, we are learning that this advice was bogus. A recent landmark health study has concluded that there has never been a link between saturated fats and heart disease. The “settled science” on nutrition wasn’t quite so settled.
Guess it just goes to show when money and science are mixed, money wins everytime.
