Does the enormously complex issue of #climatechange have to be presented to policymakers, and therefore the public, as the behemoth it really is?

Today I released my second #infographic explainer on the @IPCC_CH #AR6 reports.…

#SummaryForPeople 🧵
The amazing @skepticscience is even featuring it today, with added commentary, a real honour for a mere student of scientist.…

@theresphysics @BaerbelW @johnfocook @KenCaldeira
So, what does this, the longest explainer I've made yet, actually say?

Like the first edition —… — it kicks off with context about how we arrived at #IPCCAR6, on the @IPCC_CH itself and how it goes about communicating uncertainty.
Then it presents three nutshells. OK, acorns.
First, the problem statement.

Very simply, CO2 makes up about 75% of humanity’s heat-trapping emissions and is the gas we must unequivocally drive to #netzero as quickly as possible this century.
What are CO2 emissions doing?

Still growing. But slowing. [We] Gotta get going.
Any #climateinfographic would seem bare without the proverbial bath. How do we stop climate change and prevent the bath from overflowing?

Going #netzero, in all of its naked glory, of course.

'The Good, the Bad, the Ugly and the Great'

Granted, doesn’t roll off the tongue quite like the spaghetti Western title, but one of the golden rules of #climatecomms is to close on a positive, upbeat tone.

The good news is there's lots of GOOD to start us off. @GlobalEcoGuy
The Bad, and the baddy: fossil fuels.

@CarbonBubble @TransitionZero @matthewcgray @ClimateAd @KetanJ0
The Ugly. The @IPCC_CH tells us ‘we are not on track to limit warming to 1.5°C.’ That’s a profound understatement.

The ugliest aspect of climate change, by far, is that the door that was once open is closing fast.
And The Great. It’s very simple: #stoppingclimatechange will not cost the Earth.

In fact, the cost of #notzero is likely more than the investment required to achieve #netzero.
Low-hanging fruit has sometimes been synonymous with low-impact. Not anymore. As the #IPCCReport stresses:

*There are cheap options available now in every sector that can at least halve emissions by 2030.*

@ProjectDrawdown @hausfath
I guess the 'Tree of Solutions' is better than the 'Tree of Marginal Abatement'? @GernotWagner @ChiefExecCCC

One low-hanging fruit a day can keep our emissions at bay.
According to the @IPCC_CH, behavioural and cultural changes represented a ‘substantial overlooked strategy’ that have been left out of transition pathways and scenarios for too long.

So I wasn’t about to overlook it.

@StuartBCapstick @CAST_Centre @GretaThunberg
Models and storytelling are unlikely bedfellows, but that’s the best way to think about @IPCC_CH scenarios that help us peer into the future 🔮.

I was lucky to work with IPCC scientist @SISeneviratne to bring these stories to life a couple of yrs ago:…
We’re almost there.

An oversimplified take on possible climate futures. All three - including @CFigueres ‘necessary, achievable and desirable’ future - have one crucial thing in common: each relies on the decisions we make now and over the next few years. @OutrageOptimism
Few beyond those deeply enmeshed in CO2 removal (#CDR) know much about it, so I felt it deserved special attention.

I'm cooking up a dedicated CDR explainer for the @NetZeroTracker later this year: Is it a moral hazard or a necessary evil?

@drvolts @Noahpinion @stv_smth
Finally, we arrive at #TheBottomLine, inspired by someone who regularly illuminates my Twitter feed with clarity and level headedness: climate scientist and communicator @hausfath. @CarbonBrief @KHayhoe
Because seeing is learning, my hope is that this slightly belated #IPCC #explainer will be used as a visual reference point to support the concise communication of what matters to those who matter before #COP27

@cathmckenna @_chloeswarbrick @DavidPocock @jacindaardern @trussliz
It takes a tribe to build an #infographic, especially one as lengthy as this.

A special thanks to the maestro @_richardblack for patiently helping me out with this one. #SonofZeus. And to @CommsNerd 👌
Student of *science* (and scientists)
Cc'ing @ProfCMitchell, @DLwasa, @HeleendeConinck, @ShobhakarAIT and @Fatima_Denton. No sign of Lavanya on here, unfort! Happy to consider adding anything you think deserves a mention. (Yes, it was supposed to say 'student of science')

#OnThisDay a year ago the @IPCC_CH released its report on #climatescience. Governments endorsed then largely ignored.

How do we get IPCC summaries across to apes with smartphones, especially those roaming corridors of power for whom they're intended? 🧵…
With much difficulty. But visuals help. They not only steal attention, they have the ability to go directly into long-term memory where they're indelibly etched.

@KateRaworth @waitbutwhy @jamespeshaw
Hence why I made a belated #explainer of the first #IPCCAR6 report, the first of three I'll publish before #COP27.

Better late than never, esp. when the next IPCC compendium won't drop until ~2030, the year when interim carbon-cutting pledges should be being met.
