The assessed remaining carbon budget and its uncertainties.
Shaded blue horizontal bands illustrate the uncertainty in historical temperature increase from the 1850–1900 base period until the 2006–2015 period as estimated from global near-surface air temperatures, which impacts the additional warming until a specific temperature limit like 1.5°C or 2°C relative to the 1850–1900 period. Shaded grey cells indicate values for when historical temperature increase is estimated from a blend of near-surface air temperatures over land and sea ice regions and sea-surface temperatures over oceans.

While her answer to the question of climate, the gigaton carbon budget and all that is '420' , the absence of the more than 420 acronyms it took to keep the report under 1000 pages makes one wonder if the authority figure's handlers have read the whole thing?
