Obviously we need to do something about global warming if we want to prevent heatwaves and other weather extremes from becoming more and more frequent in every region across the globe. The best way to do it is to stop adding CO2 and other greenhouse gases (GHGs) to the air as soon as possible and develop new technologies for removing large amounts of carbon from the atmosphere. I seriously hope that sufficient efforts for reaching carbon neutrality can be coordinated globally before a truly devastating and deadly heatwave occurs. That would be a terrible wake-up call.
