Why do people still deny climate change despite worsening heat waves?

Heat waves are become more and more intense, frequent, and longer every year. There are well-documented upward trends in heat-related deaths, fires, and impact on our environments and wildlife. But, after seeing and hearing and experiencing these themselves, why do some people still deny climate change and global warming?

For those that do believe in climate change and global warming, why do most of us not take action?

… are we doomed?

This app/moderator distorted my question. Original question was: ***can someone please explain to me why and how some people can deny climate change and global warming after actually seeing, hearing, feeling, and experiencing more and more heat waves that are more intense, more frequent, and more longer?***
