@blatham,
You are drawing conclusions that have no basis in fact. I merely stated that your original statement, taken from a NOAA site,that 2015 was the highest temperature on record, was seriously misleading in that the record in question included only a miniscule slice of the 4.5 billion year geologcal history of the earth. I also accurately noted that there had been much longer periods in the earth's geological history with much higher temperatures than recorded in that "record". I could have also added that, since then, there have been at least three ice ages in between.
None of that proves that we are not in a stage of sustained warming abetted by human activity. However none of the NOAA data proves that we are in such a stage either.
The question is should we surrender control of our economic lives to incompetent zealots, who are convinced that doomsday is at hand, and whose prescriptions for what we must do don't make any sense at all.
Consider these facts. Far more reductions in our GHG emissions have been achieved through the use of nuclear power for electrical power generation, and through the transition from coal to petroleum and from petroleum to natural gas (each stage significantly reducing the carbon load), than have been acchieved or even been contemplated through wind or solar power generation. Despite that, these zealots prescribe less nuclear power, less natural gas and more wind and solar - despite the fact that they cost more than three times as much and offer no meaningful hope of near term improivement. That is insanity. No one who advocates that as a solution to a presumed GHG problem should be taken seriously.
Could all these sages be wrong ? The historical answer is yes. The inquisitors who defended Aristotle and condemned Gallileo were the academic elites of that age. There are numerous episodes of enthusiastic public madness in the historical record,m and only a fool believes we have outgrown human nature.
