Global greenhouse gas emissions reach historic high, study reveals

The world is quickly running out of “carbon budget”, the amount of carbon dioxide (CO2) that can be dumped into the atmosphere if we are to stay within the vital limit of 1,5°C above pre-industrial temperatures, according to a study published in the journal Earth System Science Data (🇬🇧) this Thursday (8).

Brazil records increase in greenhouse gas emissions

In 2021, Brazil had the second largest increase in greenhouse gas emissions in almost two decades, according to a report released this Thursday (23), by the Climate Observatory, Amazon Environmental Research Institute (Ipam) and other partner entities. That year, the volume grew 12,5% ​​and reached 2,4 billion gross tons, only lower than that recorded in 2003, when it rose 20%. 🏭

Only around 250 billion tonnes of carbon dioxide can now be emitted, to avoid the build-up of CO2 in the atmosphere that would raise temperatures by 1,5ºC. This is down from 500 billion tonnes just a few years ago, and at current annual emissions rates greenhouse gases, of around 54 billion tons per year in the last decade, would end well before the end of this decade.

Professor Piers Forster, director of Priestley Center for Climate Futures from the University of Leeds and lead author of the paper, said in an interview with The Guardian (*): “This is the critical decade for climate change. Decisions made now will have an impact on how much temperatures will rise and the degree and severity of the impacts we will see as a result.”

He said the rate of annual increase in emissions has slowed, but much stronger action is needed. “We need to change policies and approaches in light of the latest evidence about the state of the climate system. Time is no longer on our side,” he stated.
