If the world continues with current levels of emissions, there is a 50 per cent chance that global temperature rises will hit only 1.5°C – the threshold imposed by the Paris Climate Agreement – in nine years, they said.
The Global Carbon Project has involved more than 100 scientists from 80 organisations across 18 countries, and its results – published in the journal Earth System Science Data – come as countries meet for the COP27 round of climate talks in Sharm El-Sheikh, Egypt.
The new report projects total global CO2 emissions of 40.6 billion tonnes (GtCO2) in 2022, up slightly from 2021 and close to the record 40.9 billion tonnes emitted pre-pandemic in 2019.
The main driver of this growth is expected to be emissions from oil and gas, which are projected to rise 1.0 per cent compared to 2021, reaching 36.6 GtCO2. The increase in this type of emissions is likely explained by the delayed rebound of international aviation after the pandemic, as well...
