According to the IPCC August 2021 Report, what must occur to limit warming to 1.5°C or 2°C?

The necessity for immediate, rapid, and large-scale reductions in greenhouse gas emissions is emphasized in the IPCC August 2021 Report due to the urgent state of climate change. The report outlines that to limit global warming to 1.5°C or 2°C, significant and immediate actions are required to cut emissions in order to stabilize the climate. This involves transforming energy systems, improving energy efficiency, and implementing carbon capture technologies, among other strategies, to mitigate the impacts of climate change effectively.

While gradual adjustments in energy use, increases in renewable energy, and the adoption of electric vehicles are all important strategies that contribute to reducing emissions, they often imply a slower pace of change that may not meet the urgent timelines outlined in the IPCC report. Therefore, without the immediate and large-scale reductions in greenhouse gas emissions, the goal of limiting warming to the specified thresholds becomes largely unachievable.
