Levels of two major air pollutants have been reduced significantly since lockdowns began in response to the COVID-19 pandemic, but a secondary pollutant—ground-level ozone—has increased in China, according to new research. Maybe this unintended experiment could be used to understand better the emission regulations.

C above pre-industrial levels. If they meet all the pledges they've made for emission reductions by 2030, global temperature rise will be at 2.4° In almost all previous projections for climate, tipping events like these were far in the future. C by the year 2100 , according to Climate Action Tracker.
