12 ways to reduce cars in cities that have *already worked*, ranked by effectiveness, from screening nearly 800 papers.
Key takeaways: combine carrots for sustainable mobility + sticks to restrict cars; govt must lead.
Our new research led by Paula Kuss.
theconversation.com/12-best-ways-t… Cars are a problem: for climate, health, inequality, city space... Making cars fossil-free is necessary, but will not be sufficient for any of those goals; we need to reduce unnecessary cars as much as possible. I review the evidence for @ConversationUK:

"A litany of broken climate promises, a file of shame cataloguing empty pledges that put us on fast track to an unlivable world & climate disaster. This is what science tells us will result from our current energy policies." @antonioguterres 👏🔥

What does the new #IPCC #ClimateReport say in plain language?
I'll try to highlight what the Summary for Policymakers means with zero jargon in this THREAD. ipcc.ch/report/ar6/wg2/
If I slip or something is still unclear, let me know & I'll try to explain better!
Here goes 1/n Scientists are certain: #ClimateChange threatens people and life on planet Earth. If humans fail to rapidly reduce emissions "we will miss a brief and rapidly closing window to secure a liveable and sustainable future for all." #IPCC #ClimateReport D.5 2/n

Live-tweeting from #IPCC #ClimateReport launch now. @antonioguterres calls it "An atlas of human suffering and a damning indictment. Nearly half of humanity are living in the danger zone, many ecosystems are at the point of new return, NOW. The global energy mix is broken." 1/n "#FossilFuels are a dead end" for planet, economy. Adaptation investments work, should be 50% of climate finance. "Delay means death, now is the time to turn rage into action" says @antonioguterres.
From #IPCC #ClimateReport press conference here
2/n.

I have so many thoughts on climate motivations and framings that I wrote an inadvertent thread. I work to help people find their climate agency through identifying their leverage points for high-impact climate action (personal, collective, systemic). "Guilt" is the wrong framing. Hypothesis: The focus on "guilt/shame" frame in climate debates is related to high prevalence of "purity" values in the US (Moral Foundations Theory), whereas more secular Europe centers values of care/harm and fairness/cheating.

Interesting to see @fstockman essay in @nytopinion out the same week as our study of the #flightfree movement. It shows the discourse we identified in Sweden is indeed spreading- though I find Americans persistently mislabel moral responsibility as guilt. At my 2017 @oredev keynote, I asked @googlemaps to show CO2 emissions along w/ time as a metric to inform trip choice & help “maximize meaning, minimize carbon”. This tool has become a reality! Which is good! Bc people are bad at estimating climate impact:nytimes.com/interactive/20…

Our new study traces an important shift in not just attitudes, but also culture, re: travel behaviors.

Flying is shifting from an aspiration, or accepted hypermobile lifestyle, to a contested norm of Staying on the Ground.

Congrats @SaraUllstrom for leading this work!! Please see our new study tracing the "Takeoff of Staying on the Ground" (flight-free movement for climate) @katerav @jloistf @EricJLyman @themadstone @sarahkaplan48 @katherine_dunn @daisydunnesci @JannikeBK @sverkerlenas @adamvaughan_uk @MLKristola

"Talking about #Climate in a Rapidly Changing World"
Fabulous @DrKateMarvel keynote on writing for the public (even if it might hurt your academic career), an Up Goer Five abstract, diversity, poetry & more. THREAD of highlights:

(Env. Research 2021 conference, @IOPPublishing) Climate discussion in the US has (too) long focused on denial-- not "believing" scientific facts. But we don't just face denial, but also apathy and misunderstanding and helplessness and despair. More data, reports, powerpoints does not change people's minds, says @DrKateMarvel

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)

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

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

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)

.@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

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.

Martin Hultman finds 4 kinds of #ClimateChange denial:
1. Organized: groups that spread and support misinformation
2. Party political-ideological: political parties
3. Response: decisions incompatible with claimed climate goals
4. Everyday: ppl know but don't act.
@becc_sweden Very relevant research questions from Martin Hultman. Focus on three key actors in #ClimateChange denial: extractive industries (since 1960), conservative think tanks (1989-), and right-wing nationalism (2008-). @GeoffreySupran, @BenFranta are you in touch with Martin?

Communicating #ClimateChange: @NinaWormbs reflects on using technology (satellites) as stand-in for "seeing with our own eyes"; a scientific gaze used to support an economic claim ("melting sea ice will opens Northwest Passage shipping") becc.lu.se/event/theme-me… Scientific language needs to be precise and non-emotional; @NinaWormbs likens Rachel Carson and Jim Hansen as facing similar communication struggles to convey scientific problems in a way people understand emotionally. @becc_sweden

Agriculture is the most destructive human activity invented. Major cause of biodiversity loss, water and ocean pollution, climate pollution. @LennartLUCSUS says the root cause is using annual plants instead of perennials - a 10,000 year old mistake. Thread on his talk 👇🏽 @LennartLUCSUS Annual crops (cereals, oilseeds, legumes) are 80% of food. This means overturning soil and destroying its structure & life at least 1-2x/year. @LennartLUCSUS

Goal of @wim_carton talk on #negativeemissions is for everyone to understand twitter joke about #beccs by @DoctorVive & why it’s funny. Great meta #scicomm! Paris Agreement aims to stabilize climate thru “balance of sources and sinks”. @wim_carton gives overview of various negative emissions tech - all aim to prevent/remove carbon from atmosphere and transfer to land/geology/oceans.

Seminar by Prof Alexandra Klass (of @UMNews @UMNIonE )
on #energy transitions (not just policy) under Trump
on now, I'll be live tweeting.
Thread follows... Trump #energy priorities were a major shift: energy "dominance", revive coal industry, reduce env't regs on extractive #FossilFuels industry. "Underlying all this requires quite a bit of skpeticism on #climatechange" in DOT, EPA etc to implement. Prof. Alexandra Klass @IIIEElund
