It is useful to look at what is called the carbon budget. Wiki tells us that "It examines the “maximum amount of cumulative net global anthropogenic carbon dioxide (CO2) emissions that would result in limiting global warming to a given level”.
The remaining carbon budget for a likelihood of 83% to stay under 1.5 °C (2.7 °F) is 30 gigatonnes CO2 and estimated to exhaust this year - in 2025. With current CO2 emissions (exhaustion rate), the budget will be exhausted within the next 10 years for all likelihoods…
