Let’s begin by re-stating information about which we can be confident:
- The earth is warmer than it was sixty years ago. Mostly unreported is the warmer climate has, on balance, been great for humanity.
- Humans affect the climate in many ways.
- Continued increases in greenhouse gases, other factors equal, will promote additional warming. However, many processes affect climate. CO2 concentration is absolutely not a thermostat for earth’s temperature, especially since ocean heat content is more important than atmospheric heat content.
- We know far less about the processes governing earth’s climate than most climate practitioners would have you believe. In no way is the science settled. For example, we don’t even know the optimum temperature of the earth’s atmosphere.
- We have almost no ability to meaningfully forecast future climate. We can’t even make climate forecasts for a year or two ahead let alone decades ahead.
- “Consensus” has no role in science.
- We should slow the rate of increase of greenhouse gas, primarily through the adoption of new-generation nuclear.
- Regardless of earth’s temperature, we should build a more resilient society.
