"Red pill" climate talk from the inimitable @KevinClimate - argues 1.5°C of warming is the upper limit of what can be considered achieving the goal of Paris: avoiding dangerous climate change. Climate just responds to brutal physics, not promises. 1/ ImageImageImage "'1.5 is dead' is deliberately misleading, or a misunderstanding of science" says @KevinClimate. We'd take the medical treatment with a 1/6 chance; there is still an outside chance. Reductions needed are incredibly rapid, can't see making blue line (50%) but red possible. /2 ImageImageImageImage

Now live-tweeting the #IPCC #ClimateReport press conference, sharing results from the largest scientific effort to analyze the #ClimateAction needed for a livable future for all.
Follow here and in this THREAD:
1/ "The pace and scale of what has been done, and current plans, are insufficient to tackle climate change. We are walking when we should be sprinting. Impacts include illness and death, damage global economy, threaten our life support system." H-S Lee, #IPCC #ClimateReport /2

Scientists, don't separate activism and research, urges @JKSteinberger. We need ongoing critical reflection; only way to understand a system is try to change it. Activism critical to system change.
1/ Relatively little social science studies effectiveness of less powerful groups in making system change. @JKSteinberger shares lessons from THIS IS AN UPRISING on non-violent civil disobedience. Focus on disruption, decentralized, shift debate to your terms, choose moral sides /2

The logic of "overshoot": dominant approach (scientific, corporate, gov't) is now to temporarily exceed 1.5 or 2°C warming, then bring temperatures down using carbon removal, + maybe solar geoengineering; argument is this "buys time to finally get rid of fossils." @wim_carton Overshoot narrative relies on "rational optimism"- assumes carbon removal, solar geoengineering can be governed smoothly + responsibly. This assumption is "Rather problematic... if capitalism was rational & responsible, we wouldn't face overshoot in the 1st place!" -@wim_carton

As the climate scientist who led the independent @ResearchersDesk analysis of Sweden's political parties' climate policies, I'm infuriated to read the new government's agreement claim "politics must be in line with research and based on facts," then do the opposite. THREAD Image For example, @kdriks leader @BuschEbba told @dagensnyheter @linalund “Sweden will manage the climate transformation and meet our share of the Paris Agreement.” But our @ResearchersDesk analysis found proposals by the parties now in power will NOT meet the Paris Agreement. 2/n

Large-scale land acquisitions (foreign interests buy/lease land) often claim to support #foodsecurity.

But our study in @WorldDevJournal w/ @A_Mechiche & @Jiyagbi found deals are likely to benefit food security in only 7 African countries. 1/n🧵
sciencedirect.com/science/articl… Map of African countries studied for their food security ben Food security = available + access + utilisation + stability (@FAOKnowledge). We developed indicators of each for African countries in our study; found food insecurity across Africa decreased since 2000 (good!), but only 3 countries were relatively food secure in 2017 (bad) 2/n

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 👏🔥
#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. 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

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)
