I've been following this phenomenon online for about 20 years. Along the way I've observed a familiar progression of certain types of people. They have more or less all followed, and I believe they all will continue to follow, the following sequence of beliefs (examples drawn from memory, errors expected)
A history of the climate wars, told by me, an injured and honorably discharged veteran. Gather around the old CRT fire and listen up.
The first skirmishes, and the location of the first trenches;
1. It's not happening
(this was early 2000's climate denial). Highlights of this period were 'OMG the scientists are calibrating/adjusting the historical temperature sensors!!!', 'Models, what are they?', 'Pft, how can we even measure the temperature of the ocean with too few buoys. have you seen old ships!?', 'here is a picture of a weather station in the car park', etc etc. My personal favorite was, 'It hasn't warmed since 1998' - boy, that didn't age well.
When that position became indefensible, the 'Skeptics' retreated without pause to another fort (2)
2. It's not our fault
. This was ~2008-2010 denial I guess. Highlights of this period were 'I learned about IR absorption spectral look at this plot!' and 'Mars (the planet, not the delicious chocolate bar), look how warm it is!' and 'Its all cycles man (cue hippy music)'. As models multiplied like rabits, skeptics came to see value in them 'look this model actually shows it's not our fault'. Personally, I liked the its-all-cycles-man meme because this meant the bad ice-core data that was garbage in point #1, was cool again!
Some people are still stuck in this phase, but as their encampments become overrun, the more mobile skepticals pull up their weapons and make a partial retreat to a nearby hillock (3)
3. It wont be bad
. This is more or less the modern presentation. With the long climate war taking it's toll on the lowly 'net soldiers, they are making a final stand around 'it wont be bad'. Industrious souls, they can re-use some of the old hardware (cycles, models, etc) in the fight. Highlights of this phase are 'In the middle ages England grew delicious wine', 'Models are still bad, even worse than before!', 'Who want's to take a lovely holiday to greeeeennnn-land where it was green', 'plants and animals can adapt, have you seen my tomatoes bro?'. I smile a little when I realise that most people make this arguments do so using models and sensors they spent the last battle fighting. Oh well.
I'm not sure how much longer the rations will last at (3). I expect within the next 5 years there will be an unacknowledged surrender as the wary soldiers skip immediately to (4)
4. We cant do anything about it anyway
I've learned that if you are talking with someone about this topic, you can pretty quickly see if they are an exhausted soldier. If you sense they have retreated from one of the above listed positions to another and kept fighting, just give up and dont spend any effort talking with them. Wait until they get to point 4, and then note privately only to yourself, they have fought a worthless war and wasted their life for a pointless cause.
The ones you need to reach are the new soldiers that are re-deployed and parachute in from other online battles. They could land on any hill, 'Antarctica is gaining ice', 'There is no consensus', 'Those rich scientists', basically anywhere. The internet has made everyone angry and insane. Try to help these people if you can, but you should probably just delete your social media, go home and kiss your spouse and children, and teach them that the modern internet is a deadly and poisonous mind virus where millions of homeless drifters can scream toilet wall obscenities at you, while in the same twitter feed you can see the opinion of experts. Proximity gives legitimacy to insanity.
Professionally, I'm investing in climate engineering companies or other ventures that understand human nature (nice example here viewtopic.php?p=854664#p854664
) People don't give a damn, they would rather ride a JetSki off into the sunset screaming 'I EARNED THIS, GET SOME!!!'. That's cool, but just own your choices bro, don't try to hide behind 'skepticism'.
