Fact #1
CO2

140-million-year trend of dangerously decreasing CO2.

The warming effect of each molecule of CO2 declines as its concentration increases

Fact #3

First and foremost, CO2 is plant food.

Fact #4
CO2

In the last four glacial advances, the CO2 level was dangerously low.

Fact #5
CO2

CO2 emissions began accelerating in the mid-20th century

Fact #6
CO2

Our current geologic period (Quaternary) has the lowest average CO2 levels in the last 600 million years

Fact #7
CO2

Current CO2 levels are near record lows. We are CO2 impoverished.

Fact #8
CO2

More CO2 means more plant growth.

Fact #9

More CO2 helps to feed more people worldwide.

Modern warming began more than 300 years ago…

Fact #11

Melting glaciers confirm modern warming predated increases of CO2

Fact #12

Rising sea levels confirm modern warming predated increases of CO2

Fact #13

Temperatures changed dramatically during the past 10,000 years. It wasn’t us.

Fact #14

Interglacials usually last 10,000 – 15,000 years. Ours is 11,000 years old.

Fact #15

The last interglacial was 8°C (14°F) warmer than today. The polar bears survived. Greenland didn’t melt.

Fact #16

The current warming trend is neither unusual nor unprecedented (Part 1).

Fact #17

The current warming trend is neither unusual nor unprecedented (Part 2).

Fact #18

Earth’s orbit and tilt drive glacial-interglacial changes.

Fact #19

We are living in one of the coldest periods in all of Earth’s history.

Fact #20

For most of Earth’s history, it was about 10°C (18°F) warmer than today.

Fact #21

IPCC models have overstated warming up to three times too much.

Fact #22

For human advancement, warmer is better than colder.

Fact #23

CO2 increase is enhancing corn production… a lot

Fact #24

An “ideal” temperature is not that of 150 years ago

Fact #25

More CO2 means moister soil.
