Ultimately declaring a climate emergency is just the sort of strong executive action that Biden has been promising. This would be a step in the right direction toward addressing the climate crisis, improving the American energy sector, and protecting American families from oil and gas price hikes.
While an important issue, claims about global warming are often grossly exaggerated. The apocalyptic rhetoric of a 'climate emergency' may do more harm than good by alienating people on both sides and distracting from more pressing issues.
Although executive action on climate change will answer calls from progressives to act against the climate crisis, Biden is limited in his ability to enact meaningful change. Even if he does announce a national climate emergency, it should be taken with a grain of salt.
