I don't know what to tell you. The sensationalism is there because it's a catastrophic problem that requires major action.

There's consensus that a very bad thing is happening, its effects are already being felt, and they will get much worse over time. Scientists have tried to communicate this in every way, but people have hemmed and hawed or outright denied it for so long that it's going to be bad no matter what at this point. There are still things that can be done to reduce the impact, but the picture isn't good.
