A short🧵on our public perceptions chapter in last week's #StateofCDR report... 1/n

Download the full report here: stateofcdr.org
There are 3 broad lines of evidence for gauging perceptions: sampling large groups of people (e.g. surveys or experiments); individuals or small groups (e.g. interviews or deliberation); and big-data analysis of social media (e.g. sentiment analysis or stance detection) 2/n
In our chapter, we undertake a synthesis of the main insights from the English-language peer-reviewed scientific literature on public perception and an analysis of Twitter activity on the topic over time 3/n
Evidence in the scientific literature on how people perceive CDR is growing but still small. This figure shows the number of research papers on public perception of CDR by year and CDR method 4/n
Our review found large regional disparities in the peer-reviewed research on public perceptions of CDR. Only ten of the papers reviewed researched public views outside of Western Europe and North America 5/n
The scientific literature on public perceptions consistently finds low levels of awareness and knowledge of CDR in the populations of the countries studied 6/n
Research shows that people’s reactions to CDR are tied to their values, beliefs and sense of identity. Factors include trust in the actors involved, beliefs about tampering with nature, and perceived trade-offs against other approaches for tackling climate change 7/n
Attention to CDR on Twitter has proliferated in recent years, growing faster than attention to climate change in general 8/
Here’s a breakdown on the number of tweets per year on general CDR and method-specific CDR (panel A) and the relative shares of overall CDR tweets by method (panel B) 9/
Sentiments in tweets are generally positive (except for ocean fertilisation), and the trend in sentiment is positive (except for BECCS) 10/n
Future needs: Engaging the public with CDR requires policymakers and investors to understand the nuances of how different methods are perceived, extending beyond English-language scientific literature 11/11

How do the public perceive climate tipping points? 🧵

Check out my new research in Public Understanding of Science @SciPublic

Public perceptions of climate tipping points

@SciPublic @GeographyUOM @UoMNews @UoM_MERI @QEGMan Climate tipping points – critical thresholds at which a small perturbation can abruptly and/or irreversibly alter the state or development of a system – are risks that can't be ruled out

There’s great background on this by @dvdmckay @wang_seaver @hausfath and others 2/11

I show how annual trends in coverage of climate tipping points have rapidly increased in British print media and global English language online media over the past twenty years 3/11

A pleasure to speak to @adamvaughan_uk @newscientist about the launch of @Climeworks new #Orca direct air carbon capture and storage facility - capable of removing 4000 tCO2/yr - in this week's Fix the Planet newsletter. A short 🧵 on my reaction...
We should absolutely welcome the Orca facility. Although still only small in the great scheme of things, it’s a significant step forward in showing to the world that DACCS *can* be scaled up, at least in a technical sense
But they will also have to demonstrate that it can be scaled up economically and socially, too. One of the longstanding criticisms of DACCS is that is that it’s very expensive, though there are hopes that costs could be brought down significantly in the longer term

Unnatural climate solutions? Why the hype around ‘natural’ climate solutions threatens us all. New commentary by me and @shannonosaka in @NatureClimate nature.com/articles/s4155… @GeographyUOM @InSIS @SERG_Geog_UoM @UoM_MERI #Cop25Madrid2019 #COP25 #ClimateChange Image
@shannonosaka @NatureClimate @GeographyUOM @InSIS @SERG_Geog_UoM @UoM_MERI Natural climate solutions are rapidly rising up the #ClimateAction agenda with promises of lower costs, greater readiness and fewer risks than emerging technologies for carbon removal like BECCS or @DKeithClimate’s direct air capture and storage Image
@shannonosaka @NatureClimate @GeographyUOM @InSIS @SERG_Geog_UoM @UoM_MERI @DKeithClimate They (tree planting in particular) feature prominently in UK election manifestos on the #ClimateEmergency, with Labour pledging an ‘ambitious’ amount, Tories 75k p.a., Lib Dems 60 million p.a., and Greens 700 million by 2030 via @CarbonBrief Image
