Global Warming: Velocity and Acceleration of Change in Cumulative CO2 Emissions

Nowarski, Joseph

This publication introduces two parameters related to cumulative CO2 emissions. The first parameter is “Velocity of Change in Cumulative CO2 Emissions”, VCCO2. This parameter represents an average annual change in cumulative CO2 emissions and is expressed in ton of CO2 per year.

The second parameter is “Acceleration of Change in Cumulative CO2 Emissions, ACCO2, and is expressed in ton of CO2 per year, per year (tCCO2/y2).

These two parameters are in addition to the parameter “Global Warming Rate”, GWR [°C/y], and “Global Warming Acceleration”, GWA [°C/y2], described in the previous publication.

The velocity of change in cumulative CO2 emissions, VCCO2, is +35.33 GtCCO2/y in the last 11 years, and the acceleration of change in cumulative CO2 emissions, ACCO2, is +0.559 GtCCO2/y2 in the last 31 years.
