......the complexity of dealing with climate change, energy production, public health, agriculture, potable water supply, flood control, air quality, waste disposal, population and population movement, and a myriad of other problems to consider if we want to continue to eat, breathe, and turn on the lights. The word "complexity" doesn't do it justice.
Just read an article about the Three Gorges Dam in China and how climate change has affected it's original plans for power generation, flood control, erosion control and irrigation. Affected all of these things and more and none of them in a good way.

Edit: Had to look up "CCUS" - Carbon Capture, Storage and Utilization. Rather than just not producing CO2.
Gratuitous Addenda: "An atmosphere of vituperation and dishonest fearmongering" - NN, nicely put.
