Best then to spend the billions and trillions on cleaning up the actual harmful pollutants in fossil fuels. CO2 is not a problem. All of the CO2 contained in fossil fuels used to be in the atmosphere. We are just putting it back where it belongs.

If the oceans are warming then they cannot absorb CO2. Not from the air at least. Warming oceans actually release CO2. That's actually where much of the rise in atmospheric CO2 has come from.

Warmer oceans can result in longer, stronger storms, flooding, etc. Hot weather is already blamed for deaths in the United States each year.

Record crop yields in the supposed hottest year ever:
FAO Cereal Supply and Demand BriefÂ*| FAO | Food and Agriculture Organization of the United Nations
Southeast AgNET » Archive Corn, Soybean Production Up in 2016 - Southeast AgNET
The only thing raising the price of food is carbon taxes and turning food into biofuel in an attempt to reduce CO2.
There were fewer major tropical cyclones making landfall in 2016 compared to 2015. Tropical cyclone numbers for 2016 were below the 40-year average.
More deaths from cold than heat:

Please show me in the Earth manual where it states what the normal, natural balance of CO2 in the atmosphere is.
CO2 levels are far nearer to 0 than at almost any other time in the geologic record. For most of history they have been much, much higher than now. Why do you assume that almost deathly low is normal while higher is abnormal?
Again, current "average" temperature is well below what it has been for much of the geologic record.

It cannot radiate heat back towards the ground because that violates the law of thermodynamics. It can radiate heat into the cooler atmosphere but that just leads to more convection which helps move heat out into space. The Earth is not a glass topped greenhouse that physically traps heat. The atmosphere is fluid and dynamic and it is not a closed system.
