Hi, it’s your friendly neighborhood climate scientist. Facing the #climatecrisis is tough! Here’s the essentials you need to know, tips for finding where you can contribute with purpose and meaning to the work needed, and evidence-based high-impact climate actions. A THREAD: 1/n
(A quick introduction if we haven’t met: I’m a climate and sustainability scientist @lunduniversity in Sweden. I research personal & policy climate solutions, sustainable food & land systems, & wine & climate change. My goal: a world where people and nature can thrive. 2/n)
@lunduniversity #ClimateChange science has been clear for a long time. I’ve taught this framework for over a decade:
It’s warming
It’s us
We’re sure
It’s bad
We can fix it.

@lunduniversity @ylld Humans are heating the planet mostly by burning fossil fuels like coal, oil, and gas. Deforestation & agriculture cause the remaining heating (and most of the #BiodiversityCrisis). To stop warming, we have to leave #FossilFuels in the ground very extremely fast. 4/n
@lunduniversity @ylld We’re sure: There is overwhelming scientific consensus (agreement on a question of fact) that it’s humans warming the climate.

In fact, humans likely more than 100% of warming! See @hausfath .
It’s *really* bad: One of the hardest parts of my career is watching dire climate predictions come true, including in places I love. My family evacuated in the 2017 fires made worse by human-caused heating. Thankfully they stayed safe, but friends lost homes and even lives. 6/n
So how do we find the courage (h/t @DrKateMarvel) to face the #ClimateCrisis?
I talked about the Five Stages of Radical Climate Acceptance:
1. Ignorance
2. Avoidance
3. Doom
4. All the Feels
5. Purpose
on @TheWorld w/ @MarcoWerman @ASKusmer

I've found there’s no way out but through: you have to face the uncomfortable feelings from the #ClimateCrisis including grief, fear, anger. I wrote about my climate grief for @theguardian:
I also write about my anger at what it feels like to be a scientist in a world that sometimes doesn’t want to hear the truth, in this piece on loving the Earth, but hating the hypocrisy and greenwashing of Earth Day:
Please follow and listen to climate scientists, like @coralsncaves, @JacquelynGill, @KevinClimate, @Peters_Glen. @KHayhoe has a comprehensive list of "scientists who do climate". To get your climate news straight from a climate scientist: wecanfixit.substack.com
For more righteous climate anger, I recommend heated.world by @emorwee and hot-take.ghost.io/otherposts/the… by @amywestervelt & @MaryHeglar. Check out @Zlevo research on how climate anger can protect your mental health!
More and more scientists are having to grapple with how we keep up the strength and health to keep doing this work, and how we can support students who are running into a house on fire, as @DavidMalakoff wrote for @science:
A great resource for staying sane in the #ClimateCrisis is Gen Dread, by @brittwray. I've found really useful and actionable advice there on taking care of myself and others, and on building the community we need to get through this together.
So how do you figure out your core values, and how to put them into practice to both create personal meaning and work towards climate stability? I discussed w/ @SigalSamuel for @voxdotcom:
Okay, let’s get practical. What can YOU actually DO, as a citizen, community member, and consumer, that makes a real difference for the #ClimateEmergency? Let’s look at the evidence.
Here’s what effective *collective* climate action actually looks like:

1. Vote (new study: wecanfixit.substack.com/p/voting-conse…)
2. Get politically active
3. Create media attention
4. Contact your rep (here’s what to say wecanfixit.substack.com/p/people-lie-a…)

Re: media attention: Some dedicated folks have been covering the climate story for years. Follow them and support their journalism! twitter.com/i/lists/129522…
But media needs to MASSIVELY step up their climate coverage. #EndClimateSilence by @DoctorVive is working on it!
How will we solve the #EcologicalEmergency? No silver bullet, but the most important step is more #PlantBased diets. I got to answer @rufuswainwright's food & #climate question on the impact of food choices, & hear a gorgeous song from his home studio: climatecontrolprojects.com/events/rufus-w…
@rufuswainwright Here’s how you can rewild your yard, grow more food where you can, support sustainable farmers: wecanfixit.substack.com/p/climate-fact…
More fundamentally, we need to rebuild our relationship with nature; here's a plan for making a hot date with Planet Earth: wecanfixit.substack.com/p/voting-conse…
@rufuswainwright We need policy changes to stop investing in, expanding, and supporting #FossilFuels. YES, AND: we cannot stabilize the #climate without high emitters (= high earners, $38,000 and up) reducing our own overconsumption, particularly flying and driving. wecanfixit.substack.com/p/pre-fire-dre…
@rufuswainwright .@themadstone wrote a great piece for @grist on why we need individual climate action from the rich grist.org/culture/cuttin….
@sethwynes & I found the most effective #climate actions are to go flight, car, & meat-free. Start by cutting at least half from where you are now. 21/n
High school and university education is currently failing at teaching #ClimateLiteracy and preparing climate citizens. kimnicholas.com/climate-educat…

If you're an educator, check out our curriculum for teaching #climate based on #IPCC: kimnicholas.com/climate-change…
Thanks for reading! This thread draws from my new book, penguinrandomhouse.com/books/665274/u….
A book club is a great way to build your climate community! I have a discussion guide here: kimnicholas.com/discussion-que…
I can join your book discussion on Zoom: kimnicholas.com/book-seminar.h…
"What can #wine tell us about the future of life on Earth?" My 40-minute talk covers the key science & solutions for the #Climate and #EcologicalCrisis, drawing from my research & that of many colleagues. Feel free to use in teaching, etc!

Busy folks (incl new parents) are using my free newsletter to build climate discussion & action groups. It's a monthly dose of facts, feelings, and action, helping you figure out what YOU can do be part of fixing the #ClimateCrisis.

@threadreaderapp unroll please
What about the economy? It needs to be aligned with a stable climate, from policies to end fossil subsidies & #divest from fossil fuels, to breaking up with climate-destroying banks (how-to: wecanfixit.substack.com/p/dont-be-foss…), decarbonizing industries & supply chains & portfolios.
More fundamentally, to make the just climate transformation we need, we have to replace the Exploitation Mindset (denying equality between people; at war w/ nature) w/ a Regeneration Mindset (respect & care for people & nature; reduce harm at its source; build resilience). 28/n

Thread /1
.@DrChrisIves proposes framework for religious beliefs as sustainability lever:
Reveal -connections btwn existing religious values and env crisis
Reflect- (using @ruthvalerio book)
Reinforce- social learning, discussion
Redirect- to more sustainable behaviors (which⬆️)
Thanks for this interesting study and great comments today Chris! I was happy to see that reading a book (combined with personal reflection and shared discussion) can spark change. :) You might be interested in this quick look at religious climate texts?

Live tweeting from the co2-budget.com conference. First up: the inimitable @KevinClimate, who never minces words. Distressingly little progress for the climate emergency, compared with covid response. 1/n
2. Reminder: It's the carbon budget, the area under the emissions curve, that determines warming. More emissions now means more (up to impossible) cuts later. @KevinClimate
3. Net zero is NOT based on a total carbon budget (which forces us to face actions demanded today). Net zero is focused on far future (2045, 2050)- generational passing of the buck to future policymakers & scientists. Assumes all tons are =, ignores GHGs, sources. @KevinClimate

Paradoxes of #FossilFuels that contribute to #CarbonLockIn, by @JPTilsted:
1. "Everywhere, yet [made] invisible" (slow violence is overlooked);
2. "needed" [claim producers] yet inherently problematic, history of self-regulation a failure;
3. Booming, yet sector in decline
#fossilfuel producers are adding massive capacity, boosted by #plastic production, but industry projections for "transformative change" continue to dispose (yellow) + mismanage (red) plastics. @JPTilsted at @LUCSUS_LU seminar 2/n
Who produces and owns #fossilfuels? Wide range of actors including int'l + national oil firms, states, but also petrochemicals, "emerging market firms". "co-evolution of energy and engineering." Indirect ownership hard to trace + reinforces lock-in, shows @JPTilsted 3/n

Webinar on tools for assessing national #climate pledges (NDCs) by @WRIClimate. @davidwaskow reminds: #ParisAgreement is meant to work thru an iterative process of increasing ambition (faster emission reductions), leading to #netzero emissions by 2050. (Thread 1/n)
The world is currently WAY over our #carbonbudget for where we need to be to align with #ParisAgreement. Orange= countries will do under any event; red = conditional (e.g., will do if they get needed finance). We have LOTSA emissions to reduce fast @davidwaskow @WRIClimate (2/n)
Of 21 indicators assessed for #ParisAgreement:
2 are on track (e.g., crop yields)
13 right direction but too slow (e.g., need electric vehicle sales to be 22x faster than now)
2 in wrong direction: forests, ag emissions

.@theAGU hosts a massive conference of Earth and space scientists every December, usually in San Francisco (photos below from previous years). My 1st meeting was in 2003 as a masters' student. In this #thread I'll share highlights from #AGU20, my first time attending virtually! ImageImage
#Agriculture (esp replacing forests with cropland) has been changing the #climate for 6,000+ years. Ancient warming made Europe + East Asia more suitable for cultivation, lengthened Eur. growing season, find @Chris_Kucharik @NRamankutty et al. #AGU20
Something cool I discovered this year at #AGU20 (thanks to @KateBrauman) is the MacGyver session, w/ hacks including a test for #COVID19 in wastewater & a system to lure vineyard pests away with mating calls instead of harmful sprays. agu.confex.com/agu/fm20/meeti…

Now virtually attending @theNASEM workshop on #Sustainability science- input to the 2021 #NobelPrize Summit “Our Planet, Our Future." Register to watch livestream below. Some highlights to follow over next 3 days #Thread
"Autocracies don't publish much data," says @MarshallBBurke. Do existing methods reinforce existing problematic power structures & unsustainable patterns? Given data gaps, need more ways to measure at scale to be able to shine a light on and potentially address power imbalances.
"Equity is about justice and achieving equality of outcomes, so that everyone can see the football match" says @mleach_ids. Seven forms of equity interact to drive how groups experience the world. ImageImage
