All of that is based on the premise that the economy will tank if do anything to address global warming. But that is the same argument that has been leveled at every attempt to fix an environmental or social problem, like banning CFCs to stop destroying the ozone layer, or stopping the dumping harmful chemicals in any old place without a care for the health effects, or improving safety in factories to prevent workers dying from the chemicals they use, or the abolition of slavery, etc.
And yet here were are after all those changes. The economy wasn't destroyed, and scientific research is still being funded. That is because the economy adapted, as it always does. In this case we might have some short-term pain with the cost of converting to cleaner energy sources and technologies, but that will get forgotten once we find that we can save money by being smart about taking the energy from the air and sunlight around us. While coal miners won't be happy about the reduction of coal use, solar panel manufacturers will delight as their industry booms. While some things might cost us more as we have to find environmentally friendly ways of manufacturing goods, the work we do to reduce greenhouse gas emissions will have the effect of lowering levels of all pollutions. This will lead to a reduction in pollution-related diseases lowering the health care costs.
We will soon forget about what we had to do to fix climate change just as we have with all the other changes that I mentioned above. Eventually, some other problem will occur and nay-sayers will predict the ruin of the economy yet again.
