News from Home: How Local Media Shapes Climate Change Attitudes
Talbot Andrews, Cana Kim & Jeong Hyun Kim
Public Opinion Quarterly, Winter 2023, Pages 863-886
Abstract:
Highlighting the local impacts of climate change has the potential to increase the public’s awareness of and engagement with climate change. However, information about local impacts is only effective when delivered by trusted sources such as copartisan political leaders. Is information about climate change conveyed by local media sources similarly beneficial? We argue that local media are well positioned to communicate the local implications of climate change, thereby enhancing the public’s risk perceptions of climate change and willingness to take climate action. We further hypothesize that climate coverage by local media, the media type that is more trusted across party lines, will have a significant influence on Republicans’ climate attitudes. Using the case of Louisiana, we first demonstrate that local and national newspapers cover climate change in substantially different ways, with local media more consistently focused on local impacts. Our survey experiment of Louisiana residents reveals that Republicans viewed the coverage of a hurricane in the region more positively when it came from a local newspaper rather than a national newspaper. Furthermore, local newspapers’ climate coverage increased Republicans’ willingness to take action to mitigate climate change. These results provide insights into the effective communication of climate change to the public and the role of local media in mitigating partisan polarization.
The dark side of environmental activism
Hannes Zacher
Personality and Individual Differences, March 2024
Abstract:
In times of growing concerns about climate change, environmental activism is increasing. Whereas several studies have examined associations between environmental activism and the Big Five personality characteristics, the potential “dark side” of environmental activists' personality has been neglected. Accordingly, this study examined associations between environmental activism, the dark triad traits (i.e., Machiavellianism, psychopathy, narcissism) and left-wing authoritarianism (i.e., antihierarchical aggression, anticonventionalism, top-down censorship). Data came from 839 employed individuals in Germany. Results showed positive associations between environmental activism and Machiavellianism, narcissism, antihierarchical aggression, and anticonventionalism. Most of these associations remained significant after controlling for Big Five characteristics, demographic characteristics, political orientation, and right-wing authoritarianism. These findings suggest that environmental activism, in addition to its potential positive outcomes, may also have a dark side in terms of activists' personality.
Nuclear waste in my backyard: Social acceptance and economic incentives
Petyo Bonev et al.
Energy Policy, February 2024
Abstract:
We evaluate a political market mechanism for siting nuclear waste repositories to local communities. This mechanism consists of a local referendum and economic incentives offered to the local population. Using a randomized choice experiment, we find that the political market mechanism decreases the Not-In-My-Backyard opposition in the case of nuclear waste.
Do Firms Mitigate Climate Impact on Employment? Evidence from US Heat Shocks
Viral Acharya, Abhishek Bhardwaj & Tuomas Tomunen
NBER Working Paper, December 2023
Abstract:
How do firms mitigate the impact of rising temperatures on employment? Using establishment-level data, we show that firms operating in multiple counties in the United States respond to heat shocks by reducing employment in the affected locations and increasing it in unaffected locations, whereas single-location firms simply downsize. Workforce reallocation, aimed at preventing heat-related decline in labor productivity, is stronger among larger, financially stable firms with more ESG-oriented investors. The scale of this response increases with the severity of climate disasters and is aided by credit availability and competitive labor markets. Climate risk management by firms mitigates the impact of heat shocks on aggregate employment but induces a spatial redistribution of economic activity.
Climate Change and Adaptation in Global Supply-Chain Networks
Nora Pankratz & Christoph Schiller
Review of Financial Studies, forthcoming
Abstract:
This paper examines how physical climate exposure affects firm performance and global supply chains. We document that heat at supplier locations reduces the operating income of suppliers and their customers. Further, customers respond to perceived changes in suppliers’ exposure: when suppliers’ realized exposure exceeds ex ante expectations, customers are 7% more likely to terminate supplier relationships. Consistent with experience-based learning, this effect increases with signal strength and repetition and decreases with country-level climate adaptation. Subsequent replacement suppliers show a lower expected and realized but similar projected heat exposure. We find similar results for suppliers' exposure to floods.
Genomic evidence for West Antarctic Ice Sheet collapse during the Last Interglacial
Sally Lau et al.
22 December 2023, Pages 1384-1389
Abstract:
The marine-based West Antarctic Ice Sheet (WAIS) is considered vulnerable to irreversible collapse under future climate trajectories, and its tipping point may lie within the mitigated warming scenarios of 1.5° to 2°C of the United Nations Paris Agreement. Knowledge of ice loss during similarly warm past climates could resolve this uncertainty, including the Last Interglacial when global sea levels were 5 to 10 meters higher than today and global average temperatures were 0.5° to 1.5°C warmer than preindustrial levels. Using a panel of genome-wide, single-nucleotide polymorphisms of a circum-Antarctic octopus, we show persistent, historic signals of gene flow only possible with complete WAIS collapse. Our results provide the first empirical evidence that the tipping point of WAIS loss could be reached even under stringent climate mitigation scenarios.
Fast upper-level jet stream winds get faster under climate change
Tiffany Shaw & Osamu Miyawaki
Nature Climate Change, January 2024, Pages 61-67
Abstract:
Earth’s upper-level jet streams influence the speed and direction of travel of weather systems and commercial aircraft, and are linked to severe weather occurrence. Climate change is projected to accelerate the average upper-level jet stream winds. However, little is known about how fast (>99th percentile) upper-level jet stream winds will change. Here we show that fast upper-level jet stream winds get faster under climate change using daily data from climate model projections across a hierarchy of physical complexity. Fast winds also increase ~2.5 times more than the average wind response. We show that the multiplicative increase underlying the fast-get-faster response follows from the nonlinear Clausius–Clapeyron relation (moist-get-moister response). The signal is projected to emerge in both hemispheres by 2050 when considering scenario uncertainty. The results can be used to explain projected changes in commercial flight times, record-breaking winds, clear-air turbulence and a potential increase in severe weather occurrence under climate change.
The Cost of Climate Policy to Capital: Evidence from Renewable Portfolio Standards
Harrison Hong, Jeffrey Kubik & Edward Shore
NBER Working Paper, December 2023
Abstract:
Many US states have set ambitious renewable portfolio standards (RPS) that require utilities to switch from fossil fuels toward renewables. RPS increases the renewables capacity, bond issuance, maturity, and yield spreads of investor-owned utilities compared to municipal producers that are exempted from this climate policy. Contrary to stranded-asset concerns, the hit to overall firm financial health is moderate. Falling cost of renewables and passthrough of these costs to consumers mitigate the burden of RPS on firms. Using a Tobin’s q model, we show that, absent these mitigating factors, the impact of RPS on firm valuations would have been severe.
