Global warming is based on the rise of average temperatures as recorded by Man.
According to NASA and most climate scientists, reliable global temperature records have been kept since around 1880.
144 years.
Today, we know from radiometric dating that Earth is about 4.5 billion years old.
144 ÷ 4,500,000,000 = 0.000000032
That is hard to comprehend. So, let’s see how many seconds in a year that equates.
365 × 24 × 60 × 60 = 31,536,000 Seconds in a year.
31,536,000 × 0.000000064 = 2.018304 Seconds
So, the amount of recorded temperatures that is currently being used for a conclusion of global warming is perspectively the same as a 2 second observation in an entire year.
