Has COVID Affected Climate Change? - We Asked a NASA Scientist

Greenhouse gas emissions decreased a little during the first year of COVID, but not enough to make a lasting impact.

But greenhouse gases that cause climate change only decreased a little because we were still heating and cooling our homes, so these gases continued to build up in our atmosphere. NASA climate change scientist Lesley Ott tells us more about what scientists discovered.
