▶ Watch Video: “CBS This Morning” brings stories from around the globe for Earth Day

As President Biden prepares to host world leaders for a virtual climate summit this week, most Americans continue to think climate change needs to be addressed urgently, and eight in 10 would have the U.S. be at least part of an international response to do so, including those who want the U.S. to lead such an effort. Almost half think the U.S. should lead, and another third would have the U.S. take part if other countries respond too.

More broadly, over half of Americans think climate change needs to be addressed immediately; another one in 10 think it needs to be addressed in the next few years.  

And people who see the issue as more urgent overwhelmingly think the U.S. should be engaged globally on the issue. 

Some say action on climate can wait or that none needs to be taken. A combined third of Americans feel this way, including most Republicans. The top reasons they give are that they feel climate change is being exaggerated or not really happening (36%); that there are more important issues to deal with right now (31%); that there’s nothing we can do about it anyway (23%) and that it costs too much to address (9%).
