Current climate debate
No disagreement:
• CO2 has been increasing
• Nearly all of the CO2 increase is man-made
• Temperature has risen ~0.85°C (1.5°F) since 1850
Serious disagreement:
• Increase in temperature is primarily due to man-made increases in CO2 (plus other greenhouse gases) OR
• Increase in temperature is driven primarily by natural forces with a small influence from man-made causes
• Are the changes very harmful or beneficial?

There is no unusual or unprecedented warming
Heat waves have been declining
Severe weather is not increasing
Crop and forest growth are increasing
Droughts are in decline
There is no increase in hurricanes
Complete elimination of carbon dioxide emissions within Virginia will have an impact that is so close to zero that it is meaningless

In short, there is no climate crisis and any attempts to eliminate CO2 via regulation or taxation are simply “solutions in search of a problem.”
