Scientists:

1. Warming is underestimated.
2. Warming is faster than expected.
3. Warming of 2- 4°C looks certain.
4. Warming of 4°C kills 7 billion.
5. Warming of 4°C by 2045 possible.
6. Warming of 4°C by 2095 likely.
7. Warming is just 1 of 10 existential threats media ignore.
For a long time many scientists have said temperatures will exceed 2°C:


3°C or 4°C could well hit this century:

1.

2.

3.


2.5°C - 5°C now looks inevitable this century in my opinion.
An article from over 2 years ago with well known figures commenting on how we'll go over 2°C.

Guardian, NYT etc have great articles on climate breakdown, but their ad-dependency & corporate-friendly vision leads them to downplay ecological catastrophe.
Scientists have suggested that only 1 billion people could survive on a 4°C Earth:

Peer-reviewed science exists showing that warming could 'exceed 3.5–4C by 2050':

See this thread for further details:
93% chance global warming will exceed 4C by the end of this century (BAU emissions):

5C - 6C 'enough to wipe out most life on the planet':

5C- 6C by 2065?

Irreversible feedbacks have already been triggered.

Threats:

1. Deforestation
2. Chemical/plastic pollution
3. Insect/Pollinator destruction
4. Ocean acidification/deoxygenation
5. Soil degradation
6. Collapse of ecosystems
7. Industrialised agriculture/Overfishing
8. Global Pandemic
9. Nuclear catastrophe
10. New technologies

As if climate breakdown and ecological collapse weren't grim enough. Here's a recent article on extinction by catastrophic pandemic:
