Did you know:

To determine atmospheric CO2 concentrations air samples are regularly collected from observatories, tall towers, aircraft, and weather balloons at 86 locations worldwide. (See https://gml.noaa.gov/dv/site/?program=ccgg&active=1)

In addition, NASA’s Orbiting Carbon Observatories, OCO-2 and OCO-3, make around 100,000 measurements around the world each day.

These instruments ALL show the rising CO2 concentration trajectory.

We can’t say we didn’t know!
