Since 1950 CO2 has been increasing at least 100 times faster and has risen 32% greater than in the prior 800,000 years. C02 is currently higher than it has been in 15 million years. The recent CO2 increase was directly measured by instruments and the 800,000 year old values were directly measured from air bubbles trapped in columns of ice.
A sufficiently steep carbon fee ensuring carbon reduction targets are definitely met on schedule along with a corresponding carbon dividend minimizing the transition burden to the public. The dividend would aim for the average person to break-even throughout the whole transition process. The fail-safe makes sure the fee is high enough to meet carbon emission reduction targets. The safeguard keeps the fee from getting any higher than needed.
