One way to shut down a climate alarmist:
What are the current calibration standards for climate data collection stations? What percentage of stations adhere to those standards? At what level of uncertainty are the data points measured?
What is the level of uncertainty for data points from 25 years ago? 50 years ago? 100 years ago? 200 years ago?
How about the guestimates from thousands of years ago?
What, then, is the uncertainty of your predictions given the uncertainty of your data points? Why aren’t those ever included in your predictions?
If your predictions are within the uncertainty of your measurements, then they are insignificant. This is basic high school science.
And another way: ask this, “lets assume for a moment the earth is warming and has been for a while. Therefore it is too warm, correct? To what temperature should we strive to cool the earth and what are you basing that number on, i.e. what is THE CORRECT temperature for the earth?
