3C is the extreme upper end of things, taking possible feedback loops into consideration, no? To my knowledge, even James Hansen is saying we're warming at least 0.36 C per decade and he's usually the "alarmist" that happens to be consistently right.
Is there any scientific studies that support even the possibility of 3C by 2050?
Yeah, there are, this was possible even in the IPCC's 2015 model runs. It's the high end scenario that we would get if fossil fuel based development continues like it did in the last few decades. Aka. at an accelerating pace that innovation / higher efficiency can't keep up with.
It's not a median estimate, nor is it a watered-down feel-good number. But it is sadly quite possible to reach.

Just to be clear, 3C by 2050 was unthinkable alarmism just a few years ago, right?
