Science

Facts and data about climate change.

1. CO2 has been decreasing for 140 million years.

2. The warming effect of CO2 decreases as its concentration increases.

3. CO2 is plant food.

4. The last 4 times glaciers advanced, the CO2 level was dangerously low.

5. CO2 emmssions began accelerating in the mid 20th century.

6. Our current geologic period has the lowest CO2 levels in the past 600 million years.

7. Current CO2 levels are near record lows.

8. More CO2 means more plant growth.

9.  More CO2 helps feed people worldwide.

10.  Modern warming began over 300 million years ago.

11. Melting glaciers confirm modern warming predated increases of CO2.

12. Rising sea levels confirm modern warming predated increases of CO2.

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

14. Interglacials last 10000-15000 years. Ours is 11000 years old.

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

16. The current warming trend is neither unusual nor unprecedented.

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

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

19. For most of earth’s history, temperatures were about 10 degrees C (18 F) warmer than now).

20. IPCC models have overstated warming up to 3 times too much.

21. For human advancement, warmer is better than colder.

22. CO2 increase is enhancing corn production.

23. An ideal temperature is not that of 150 years ago.

24. More CO2 means moister soil.

25. CO2 rose after WW2, but temperature fell.

26. The only thing constant about temperatures the past 600 million years is that they’ve been constantly changing.

27. According to the NOAA, droughts are not increasing in the US.

28. Globally, droughts are declining.

29. Glacial retreat began more than 200 years ago.
