If a tree falls in the forrest and there's no one there. Who will a liberal blame for causing a sudden shift to a new equilibrium and who can be taxed?
Climate change is evolution. Libs need to quit trying to claim its a man-made revolution.
Climate change has always been happening and always will. However, the current pattern of extremely rapid warming is something that doesn't show up at any other time in at least a hundred thousand years of paleoclimate reconstruction, and the only plausible mechanism proposed for that is the gigantic uptick in anthropogenic greenhouse gases. The speed at which that warming happens will almost certainly mean serious negative repercussions for people, since it will mean the change will often outpace the ability of human societies and ecosystems to adapt effectively.
Picture it in a microcosmic way. Picture a single farm coping with a warming, drying climate. If the warming and drying is very slow (e.g., half a degree Celsius per century with commensurately slow decreases in average rainfall -- something on the pace of natural climate change patterns we saw in pre-industrial eras), adaptation won't be that difficult. Maybe it starts as a rice farm and gradually they develop more drought-resistant strains of rice, and then they start planting other crops that do better in drier climates, and building out irrigation systems, and learning new skills and habits for getting good crop yields in a warming, drying landscape, and eventually maybe even migrating.
With those changes only having to occur over the course of many generations, there's time for trial and error, and new infrastructure investments at more or less the natural attrition/obsolescence rate, so there's not much hardship associated with the trend. But what if it's five degrees Celsius per century, with commensurately rapid decreases in natural rainfall? Now we're talking repeated famines associated with crop failures, refugee crises, etc. Now the infrastructure investments have to be made at far above the natural rate of attrition/obsolescence, meaning hugely increased costs.
To put it in really simplistic terms, picture you're spending a day at the beach, and you're set up near the water line. You can cope easily with even a fifteen foot change in the height of the water, if it occurs at the pace of a normal tide. Just move your beach chair a few feet up the beach every now and then. No big deal. But if that same 15-foot rise in the water happened in just a few seconds, some people are going to drown, and even the decent swimmers are going to have their picnic baskets soaked. The speed of change can overwhelm the ability to adapt. The same happens in a much bigger picture with climate change.
That's why it's no comfort to say that climate change is always happening. Slow climate change is always happening, and for all of human history we've coped with that reasonably well. Extremely rapid climate change is a new thing, and it's going to be much harder to deal with.
