"The science is settled."
Evidently, every science evolves except global warming.
In some ways, this may not be the contradiction it seems to be. Increasingly, climate studies are not "science." By definition, science must have a falsifiable hypothesis. If global warming is responsible for:
- More polar ice
- Less polar ice
- Warmer weather
- Colder weather
- High winds
- Calmer winds
- Changes in hurricanes (not just worsening hurricanes)...
it cannot possibly be falsified. If every change in the weather is due to global warming then climate study is not science because it is not falsifiable. Why?
- The weather constantly changes and always has.
- Climate constantly changes and always has.
In fact, those who study climate cannot tell us (based on their chosen metric of surface temperatures) the ideal temperature for earth and its human residents.
Do human beings affect the weather? Of course! But, it isn't nearly as simple as changes in CO2. Humans affect the climates through greenhouse gases, land use changes, particulates, aerosols and in other ways. Climate also changes through volcanic and solar influences. The bottom line:
Even if we took atmospheric concentrations of CO2 back to 350ppm, it is highly unlikely the climate would be the same as the last time it was 350ppm.
It is a shame that global warming has corrupted atmospheric science. I doubt that issue will resolve itself in my lifetime.
