Planet earth is roughly 4.5 billion years old and during its history both the Earth’s climate and its atmosphere have changed radically. And if you’re like most of us non-scientists, there are a few things you may not know about the planet you live on.
Did you know today’s global average temperature is roughly 59°F (15°C) and that there have been periods during earth’s history when the planet’s average temperature was roughly 10°F (12°C) with ice sheets 2 miles thick covering the planet from pole to pole? Conversely, there have been times when the earth’s temperature was as high as 95°F (35°C) and ice and snow were non-existent. Meanwhile, during earth’s early history the planet had very little oxygen, but about 2.4 billion years ago the first cyanobacteria appeared and began producing it, so today oxygen is the second-most common element in the atmosphere.
You might ask, why I have included this climate trivia? I did so to illustrate that the earth’s climate, temperature, and atmosphere have experienced enormous changes during its celestial history. And looking into the future, geologists & astrophysicists also know the earth will continue to alternately warm and cool and our atmosphere change until our sun becomes a red giant and super heats the earth to the point where it will become a steaming cauldron at 900°F, just like our sister planet, Venus
Vis-à-vis the foregoing, it strikes me that the two questions that should be asked in any climate discussion are, What is the ‘ideal temperature of planet earth, and during which geologic period did it occur? But this much I promise, the UN’s International Panel on Climate Change along with their minions of climate activists won’t even consider that question much less offer an answer.

The elites at the UN have agreed (via the Paris Climate Agreement) to “hold the increase in the global average temperature to well below 2℃ above pre-industrial levels and to pursue efforts to limit the temperature increase to 1.5℃ above pre-industrial levels.”
But who established that’s goal and exactly how was that particular number established considering that the UN’s International Panel on Climate Change has never defined what pre-industrial means, begging the question, how do they intend on measuring temperatures if there’s no agreed upon baseline? Without a specific answer to that question and for the sake of argument I’ll give the elites at the UN a pass and use the year 1750 AD, i.e., 273 years ago as the pre-industrial level and our baseline.
Now let’s add some context. We know our planet has been alternately warming and cooling for 4.5 billion years, yet as noted, the elites at the UN have chosen the last 273 years for their comparison; begging another question, doesn’t the climate and all the evolutionally changes from natural forces such as the tilt of the earth’s axis, tectonic plate movement, sunspots, volcanic eruptions, etc., that have occurred during the other 4,499,999,727 years of earth’s existence matter?
As noted, we know the earth’s climate is cyclical, and for the past 3 million years, the earth has been in what climate scientists call the “Icehouse state,” characterized by alternating glacial and interglacial periods. However, prior to the icehouse state, earth’s temperature was 2°C – 3°C warmer than it was even during the pre-industrial period.
It should be obvious that by choosing arbitrary dates that fit a narrative the climate activists can “prove” anything they want. And using the “pre-industrial period,” i.e., 1750 as a starting point is tantamount measuring the temperature in New York City on January 1st, comparing it to the temperature on the 4th of July and then prognosticating a climate catastrophe by October.
