So far there has been no culling. Our warmer climate has seen the greatest increase in human population ever. Is the current warming of the planet a disaster, no it is not. The real climate disasters are
Ordovician-silurian Extinction: 440 million years ago.
Devonian Extinction: 365 million years ago.
Permian-triassic Extinction: 250 million years ago.
Triassic-jurassic Extinction: 210 million years ago.
Cretaceous-tertiary Extinction: 65 Million Years Ago.
These resulted in nuclear winters, the teal climate disasters.
We are actually in a very good climate right now. I live in south west B.C. and shoveled a lot of snow growing up, now not so much. Would the world be a better place with less carbon in the atmosphere and if the seas were less acidic? Probably. Of course our best and brightest are working on solutions. Work is being done on a pipeline across the Sahara Desert, bringing water for agriculture and the planting of millions of trees. Technology is being developed to capture carbon from smoke stacks, and from the air. One promising area is the machines that optimize algae production. The algae can then be used to make bio fuels that replace fossil fuels, and plastics that can be stored in building products, furniture, automobile products, appliances and maybe even products to pave our streets. There are plans to farm seaweed in the oceans shallow waters, taking carbon out, putting oxygen in, and balancing ph levels, and increasing marine populations. our best and brightest are working on solutions, and the Chicken Littles are running around crying "the sky is falling".
