Average temperature in the USA by www.ncdc.noaa.gov [1] for years 1990 - 2019 and the two extrapolations, linear (red) and quadratic (blue).
Abscissas: time, measured in years since birthday of Jesus Nazaretski
Ordinates: mean temperature of air near the ground at the USA, measured in scale of Fahrenheit.
