Figure 1: Surface temperatures in the Sargasso Sea, a 2 million square mile region of the Atlantic Ocean, with time resolution of 50 to 100 years and ending in 1975,
So their first graph stops 33 years ago?
Many of these estimates are from the decrease in atmospheric carbon 14 after cessation of atmospheric nuclear weapons testing, which provides a reliable half-time. There is no experimental evidence to support computer model estimates (73) of a CO2 atmospheric "lifetime" of 300 years or more.
The average exchange of carbon with biomass is has little change in the net levels of carbon but it does change what isotopes are in the atmosphere.
PS: Water, oxygen, and carbon dioxide are the three most important substances that make life possible.
They are surely not environmental pollutants.
Based on what? Oxygen above the normal range has significant negative heath impacts. It also kills of wide ranges of the planets life forms.
