What do you think climate scientists have been screaming about for the past several decades?

It always seemed like CO2 was the biggest issue. Call me naive but I didn't hear anything about massive underground methane bubbles ready to explode and destroy humanity imminently.

I heard about that problem ten years ago, without specifically looking for it. It's probably known for decades.
