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.… 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 👏🔥
#IPCC #ClimateReport presser 1/n "Government and business leaders are saying one thing and doing another. Simply put, they are lying. Climate scientists warn we are close to tipping points that could lead to irreversible, cascading impacts." @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.
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.

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…

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)

Highlights from @transform_2021 conference, June 17-18, 2021. "Enabling positive tipping points in an uncertain world."
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⬆️)

Live tweeting from the 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")… 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
