I hope they cancel all funding for the monumental waste of money on global warming, or its stealthy moniker "climate change" (as though the climate hasn't been changing throughout earth's history!)
CO2 is not only vital for its well known roles as plant food and oxygen generation via photosynthesis. It has a largely unrecognized role as being responsible for the slowly continuous vertical convection of thermal energy from the earth's surface (where it absorbs solar radiation) up to the tropopause, beyond which this energy is radiated into outer space.
Without this convective thermal "resistance" provided by CO2 and other greenhouse gases, the surface of the earth would be much colder and unable to support life as we know it. Thus CO2 is largely responsible for the single most striking feature of earth's atmosphere--the critical warm layer of the troposphere, within which life can flourish.
Current atmospheric concentrations of CO2 are 1/10 or less than those encountered in geologic times, during which the earth was much greener and life was abundant. In fact, we're not that far from a cataclysmic lower bound, below which photosynthesis would be extinguished.
It's time to stop this politically driven, model-centric gravy train! John Von Neumann once commented about models, that "with four parameters I can draw an elephant, and with five, I can make it wiggle its trunk." Those of us who have worked with models in the real world have been humbled by their frequent abject failures to reflect reality.
