METEOROLOGY – CLIMATE CHANGE & PROJECTION CALCULATOR
Warming Commitment
A precise tool.
What is the Warming Commitment & How does it work?
The concept of committed warming refers to the amount of global warming that is already ‘baked in’ due to past greenhouse gas (GHG) emissions. This warming will continue even if GHG concentrations are stabilized, as the Earth’s climate system has a significant inertia.The coefficients (alpha), (beta), and (gamma) represent the sensitivity of global temperatures to changes in each respective GHG. These values are derived from climate models and can vary based on various factors such as feedback mechanisms within the Earth system.
Delta T = alpha cdot CO_2 + beta cdot CH_4 + gamma cdot N_2O
Delta T = Committed Warming (°C)
CO_2 = Atmospheric CO2 concentration (ppm)
CH_4 = Atmospheric CH4 concentration (ppb)
N_2O = Atmospheric N2O concentration (ppb)
CO_2 = Atmospheric CO2 concentration (ppm)
CH_4 = Atmospheric CH4 concentration (ppb)
N_2O = Atmospheric N2O concentration (ppb)

Frequently Asked Questions
What is committed warming?
Committed warming refers to the amount of global warming that will occur due to past greenhouse gas emissions, even if emissions are stopped immediately.
How do I calculate committed warming using this calculator?
Input the current concentrations of CO2 (in ppm), CH4 (in ppb), and N2O (in ppb) into the respective fields. The calculator will then compute the committed warming in degrees Celsius.
What factors influence committed warming?
Committed warming is influenced by the concentrations of greenhouse gases like CO2, CH4, and N2O in the atmosphere.
Can committed warming be reversed?
While it’s challenging to reverse committed warming entirely, reducing future emissions can slow down further warming.
What is the significance of committed warming for climate policy?
Understanding committed warming helps policymakers plan for and adapt to inevitable climate changes while working to reduce future emissions.
How does this calculator differ from other climate calculators?
This calculator specifically focuses on calculating committed warming based on current greenhouse gas concentrations, offering a unique perspective on long-term climate impacts.
What are the units for CO2, CH4, and N2O in the calculator?
CO2 is measured in parts per million (ppm), while CH4 and N2O are measured in parts per billion (ppb).
