In GWP, what does the acronym stand for?

• A. Global Warming Potential
• B. Greenhouse Warming Potential
• C. Global Weather Potential
• D. Gas Warming Pressure

Answer: (A)

Global Warming Potential is a relative metric used to compare how much heat different greenhouse gases trap in the atmosphere over a given time horizon, relative to carbon dioxide. The idea is to put all emissions on a common scale: carbon dioxide is the reference with a GWP of 1, so other gases are expressed in CO2-equivalents. This helps quantify and compare the overall climate impact of releasing different gases. Understanding GWP is useful because some gases may warm more intensely in the short term but less over longer periods due to atmospheric lifetimes. For example, methane has a higher warming impact than CO2 over a 100-year horizon, so its GWP is a number greater than 1, while CO2 itself remains 1. The terms in the other options don’t reflect the standard scientific acronym used here.
