During the last ice age there is evidence that suggests the Earth's temperature rose 10-15 degrees in less than 10 years. In fact, during the last 110k years represented in the Greenland Ice Sheet Project the climate shifted dramatically multiple times over periods of a few years to maybe a couple of dozen years. During the last 110k years the most stable has been the last 11k years, which is kind of just dumb good luck for us living today.
Current anthropomorphic climate change models suggest we might see 2-3 degree changes in 100 years. I believe the science is likely accurate here. I support moving towards renewables and just about anything else generally supported by the climate change crowd. However, I think the panic button has been pushed a little too hard on this issue. I think things like overfishing the ocean and even plastics in the ocean are going to be bigger problems in the short run than human caused climate change.
Generally speaking this kind of nuance isn't allowed. The kind of response that says "If water rises a few feet, move a few feet inland, you've got a century of notice. If you have to farm over there instead of over here, then farm over there instead." is sacrilegious. To many, I would be considered a "climate denier."
The economic impact on the United States alone will be in the trillions. Relocating all of Manhattan, Toronto, London, Singapore, and other coastal economic centers is non-trivial, but would hopefully be gradual enough to be viable. It would be fantastic if we can avoid this loss of wealth by making a meaningful reduction in the rate of global warming.
Other nations are already experiencing famine due to permanent desertification. This has already exacerbated political and military conditions; drought is a major factor in the Syrian and other war zones.
To compare this to the range of human history is not meaningful. "They had it worse" isn't helpful for now. What matters is our response to the conditions that we are expected to experience.
Around the 120,000 BCE time, there was a "great filter" event that caused the mass death of most of humanity, causing a massive reduction in human genetic diversity. Yes, we may have it "easier," but today's problems are still real and must be dealt with.
I think it's useful to frame the climate change process solely in terms of human impact, and specifically economic, political, and security terms to governments.
I wouldn't consider you a denier, and it's important to share your perspective. I hope you consider mine.
The cost of the Iraq war is in the trillions. A cynic could argue that that war happened to secure burnable fossil fuels.
It isn't obvious that the cost being in the trillions is cause to blanch - at the scale we are talking, the cost of mitigating with more expensive energy is also likely to be in the trillions.
You might benefit from being more specific about how many trillions.
