The second annual Indicators of Global Climate Change report shows a rise in human-induced warming to 1.19°C over the last decade and emphasizes the critical low remaining carbon budget of 200 gigatonnes, indicating just five years of current emissions levels. The report highlights the urgency of robust climate action to combat the ongoing increases in global warming and its impacts. Credit: SciTechDaily.
In 2020, the Intergovernmental Panel on Climate Change calculated the remaining carbon budget for 1.5 °C was in the 300 to 900 gigatonnes of carbon dioxide range, with a central estimate of 500. Since then, COemissions and global warming have continued. At the start of 2024, the remaining carbon budget for 1.5 °C stood at 100 to 450 gigatonnes, with a central estimate of 200.
Although this was offset last year by the aerosol emissions from the Canadian wildfires, the report says the longer-term trend nonetheless indicates that the amount of cooling we can expect from aerosol emissions is continuing to decline.Human-induced warming has risen to 1.19 °C over the past decade – an increase from the 1.14 °C seen in 2013-2022 .
