And you are convinced that if we let the politicians spend (or direct the spending of) tens of trillions of dollars, that we will somehow save money, avoid hot weather, avoid cold weather, avoid wet weather, avoid dry weather, avoid rough weather etc., etc., etc.
Crazy! And stupid. And really, really expensive.
The only thing that matters is the infrastructure of our civilization. Our farms, cities, population centers, shore homes, etc.
We located all of that stuff based on climate (most importantly water availability) and sea level.
AGW causes ice melt which raises sea level. It also changes the distribution of precipitation. In other words, weather.
The IPCC is charged with the science of predicting both of those variables as a function of atmospheric green house gas concentration.
They are certain that increased GHG concentrations warm the climate. They do not have yet the ability to make long term weather predictions especially in a changing, less stable climate.
They are certain that if dumping new CO2 in the atmosphere stopped tomorrow the decline in concentration would be very slow.
As an example of the complexity: We know we are losing ice and snow mass today, every year. How many decades would that continue for if the climate warmed no more? What would sea level be at that point? What kind of urban relocation or diking would be required when and where from that sea level increase to prevent what cost storm damage?
Science is the only avenue open for making those predictions and we have a very long way to go.
But, we know fossil fuel supply is limited so sustainable energy is a requirement no matter AGW.
Bottom line. What rate of change to sustainable energy is the lowest total cost?
For sure it is not ignoring the problem and future.
