The warming effect of each molecule of CO2 declines as its concentration increases
In the last four glacial advances, the CO2 level was dangerously low.
Our current geologic period (Quaternary) has the lowest average CO2 levels in the last 600 million years
Current CO2 levels are near record lows. We are CO2 impoverished.
More CO2 helps to feed more people worldwide.
Modern warming began more than 300 years ago…
Melting glaciers confirm modern warming predated increases of CO2
Rising sea levels confirm modern warming predated increases of CO2
Temperatures changed dramatically during the past 10,000 years. It wasn’t us.
Interglacials usually last 10,000 – 15,000 years. Ours is 11,000 years old.
The last interglacial was 8°C (14°F) warmer than today. The polar bears survived. Greenland didn’t melt.
The current warming trend is neither unusual nor unprecedented (Part 1).
The current warming trend is neither unusual nor unprecedented (Part 2).
Earth’s orbit and tilt drive glacial-interglacial changes.
We are living in one of the coldest periods in all of Earth’s history.
For most of Earth’s history, it was about 10°C (18°F) warmer than today.
IPCC models have overstated warming up to three times too much.
For human advancement, warmer is better than colder.
CO2 increase is enhancing corn production… a lot
