India, Nov. 12 -- The world will exhaust in about six years, the remaining carbon budget before the 1.5 degrees C warming threshold is breached consistently, the Global Carbon Project's science team has projected.

The carbon budget is the amount of carbon dioxide emissions that will result in limiting global warming to a given level, in this case, the Paris accord's target of 1.5 degrees C over pre-industrial levels. This year is on track to be the first year that sees the threshold being crossed.

At the current rate of emissions, the Global Carbon Budget team estimated a 50% chance that global average temperatures will exceed 1.5 degrees C consistently in about six years.

"It's clear that the remaining carbon budget - and therefore th...
