That’s a great question!

The Royal Society did some work that showed that even if no more greenhouse gases were emitted today, it would take thousands of years for the earth temperatures to go back to how they were before the industrial revolution. https://royalsociety.org/news-resources/projects/climate-change-evidence-causes/question-20/ Even if we can’t reverse it completely, it’s important for us to make more environmentally friendly decisions to stop the earth getting worse!
