Why are you quoting some random studies and essays? I am sure that there are people who claim that "the end of the world is nigh". But this clearly is not what the majority of scientists, politicians, governments and even activists say.
Considering you are a scientist, your arguments are surprisingly superficial and, I would argue, even false. Here is what XR says in the very link you quote:
"We are in the midst of a climate and ecological breakdown. We are facing an uncertain future - our world is in crisis and life itself is under threat. Now is not the time to ignore the issues; now is the time to act as if the truth is real. The science is clear. We are in the midst of a mass extinction of our own making and our governments are not doing enough to protect their citizens, our resources, our biodiversity, our planet, and our future."
Where does it say that "Homo Sapiens" faces extinction? Do you disagree that we are "in the midst of a climate and ecological breakdown"? Do you disagree that we are "in the midst of a mass extinction"? This last claim cleary does not refer to humans. Do you disagree?
Who says that we will all die? The premise of your article is false.
Well, Extinction Rebellion rebels against the possibility of the extinction of Homo Sapiens because of climate change.
Here's a supposedly sober assessment: https://www.pnas.org/doi/10.1073/pnas.2108146119

You asked who said that so I gave you some examples. I never claimed that this is a majority view.

"life itself is under threat" means extinction of all living species
biologists disagree about what is alive and what not, but almost all* agree that humans are
*Tim Lenton thinks that 10% of humans are dead, but he is pretty much alone in this
