Interested in genetics & attitudes to climate change. Once did research - now teach mostly. Trying to figure out what to do here. Serious science stuff or bad cartoons?

I had thought that this would be similar to the commonly used,
"How concerned are you about climate change?" question.
But this seems more divided.

A question where everyone has an opinion & few intermediate views.
I'd be interested to see if there are real studies on this.

This is how these diagrams are usually presented.
Looks good (arguably better), but much less clear; I never really understood what was going on.
I prefer the new simplified linear version.

Now, in the 🇬🇧, ~25% think that "the threat of global warming is not as real as many scientists have said."
Steady increase in the last 5 years - from around 15%.
62% say the threat is 'every bit as real.

Now lots of serious climate researchers have moved here after abandoning X. What do people here reckon?
Are climate change researchers - on the whole- doing a good job at communicating?

Important results for our future #climate 🌎 🌳 🐟
Lots of people think that it will just take a modest reduction in greenhouse gas emissions 🔥 ⛽️ to solve climate change.

A study looking at the boiling 🐸 (frog) theory in communicating gradual environmental shifts.
For maximum impact, avoid continuous trends. 🌧 🌡
These have less impact than showing than binary variables (lake freezing or not freezing).

As it is Earth Day 🌎, a reminder of why serious climate action is essential:
The timescale of this graph includes:
- the period when humans transitioned from hunter-gatherer to farming.
- the start of organised societies.
- the translation to burning 🔥 fossil fuels.

The graph from the paper suggests 60% GDP, I think.
Imperfect models can be useful, though. Do you think it's just a question of highlighting the limitations in the discussion? Or should they not be attempted?
