Remember we have very little in the way of actual climate measurements past 150 years, which is a very tiny blip on the timescale of the planet. Other methods including but not limited to ice cores, tree rings, and soil cores can give us an idea of the past climate but not actual temperatures. During Roman times the data shows that the Earth had a 4-5 degree higher average temperature than we have now and it did not lead to mass extinctions.
The Asian countries which are releasing the majority of CO2 into the atmosphere have actually agreed to do nothing different from what they were already doing. What this means is that if the U.S. and other western countries reduced their CO2 emissions it would actually accomplish nothing! The same models that say that humans are creating global warming also say that it is too late for us to do anything to stop it! The big problem that we should be concentrating on is the actual pollution of the environment! Plastic is polluting everything and dangerous chemicals are showing up throughout the food chain and everywhere in the environment! This is the real danger! Stop spending money on implementing "green technology" that is not ready and often causes unintended consequences for the environment. We need to spend the money and effort on making sure that alternative energy is ready and causes no damage to the environment BEFORE we require the public to adopt it not after we realize that it is actually worse for the environment (ethanol)! Remember your electric car is actually worse for the environment over its full lifetime than an old fashioned gas or diesel burning vehicle! That problem will probably be solved in the next few years with alternative technology that is being researched right now just as our energy problems will be solved by several technologies that are also being researched including the Tokamak fusion reactor.
