The graph that you link to seems to have data up until 2022? 1.73 trillion tonnes cumulative in 2022. 837.92 billion tonnes cumulative in 1992. Hence the head

The graph that you link to seems to have data up until 2022? 1.73 trillion tonnes cumulative in 2022. 837.92 billion tonnes cumulative in 1992. Hence the headline "most CO₂ emissions were in the last 30 years", or at least I assume this.
