Climate Politics, Public Opinion, and Leader Survival

Vocabulary flashcards covering public opinion dynamics, psychological theories of risk and attention, international treaties and COP milestones, and political survival models in response to climate shocks.

Six Americas Framework

A classification identifying six distinct audiences within the American public regarding climate change attitudes, beliefs, and behaviors: Alarmed, Concerned, Cautious, Disengaged, Doubtful, and Dismissive.

Issue Salience

The relative importance or priority an individual assigns to an issue compared to other concerns; in climate politics, it explains why voters with pro-climate attitudes may still vote for anti-mitigation candidates if economic or cost-of-living concerns rank higher.

Social Desirability Bias

The tendency of survey respondents to overstate their concern or select answers they perceive as socially approved or demanded by researchers, resulting in expressed attitudes that do not translate into decisive voting behavior.

Finite Pool of Worry (FPW)

A psychological hypothesis proposing that humans possess limited emotional resources for worry, such that an increase in worry about one immediate threat (such as COVID-19) causes worry about other threats (such as climate change) to decrease.

Finite Pool of Attention (FPA)

A cognitive model indicating that humans have a limited capacity to process information and direct focus across multiple issues simultaneously, causing public and media attention to climate change to decline when a crisis monopolizes discourse.

Renewable Resources Model

A model formulated by Linville and Fischer (1991) proposing that people possess limited but renewable physiological, cognitive, and social resources for coping with emotionally impactful events.

Initial Elevation Bias

A systematic response bias where participants in subjective surveys unintentionally overestimate their distress or concerns during early waves of measurement to comply with perceived researcher expectations.

VADER (Valence Aware Dictionary and sEntiment Reasoner)

A rule-based lexicon and sentiment analysis tool specifically calibrated to assess positive, negative, and neutral sentiments expressed in social media text.

NRCLex

An affect lexicon dictionary containing approximately $27{,}000$ words based on the National Research Council Canada affect lexicon and NLTK's WordNet synonym sets, measuring emotional categories including fear, anger, joy, and sadness.

Plutchik's Wheel of Emotions

A visual structural model classifying human emotions into concentric rings of varying intensity and opposing dyads, including core emotions such as joy, trust, fear, surprise, sadness, disgust, anger, and anticipation.

Principle of Equity (UNFCCC)

A foundational tenet under the United Nations Framework Convention on Climate Change establishing that nations have common but differentiated responsibilities and varying capacities in addressing global climate change.

Historical Responsibility

The principle that industrialized nations should carry greater burdens in climate mitigation and finance because their cumulative greenhouse gas emissions since industrialization primarily drove atmospheric accumulation.

Berlin Mandate

The formal outcome of COP1 in 1995 in Berlin, Germany, establishing a political framework that recognized existing commitments were inadequate and paved the way for negotiations on binding targets.

Kyoto Protocol

A legally binding treaty adopted at COP3 in 1997 requiring developed countries to reduce greenhouse gas emissions by an average of $5.2\%$ below 1990 levels between 2008 and 2012, which excluded the United States upon entering into force in 2005.

Nationally Determined Contributions (NDCs)

Non-binding national climate action plans submitted by individual nations under the Paris Agreement, specifying voluntary emissions reduction targets that must be resubmitted and ratcheted up every five years.

Global Stocktake

A five-year cyclical review mechanism mandated by the Paris Agreement to assess collective global progress toward long-term mitigation, adaptation, and finance goals, first completed at COP28 in Dubai (2023).

Loss and Damage Funding

A financial assistance mechanism established at COP27 in Sharm El-Sheikh (2022) to provide funding for developing nations disproportionately impacted by unavoidable climate disasters.

$1.5^\circ\text{C}$ Return Pathway

A climate mitigation trajectory that permits a temporary global mean temperature overshoot to approximately $1.7\text{--}1.8^\circ\text{C}$ before drawing temperatures back down to $1.5^\circ\text{C}$ above pre-industrial levels by the year 2100 through a $45\%$ reduction in global GHG emissions by 2035 relative to 2025.

Archigos Dataset

A comprehensive political science dataset documenting the tenure, entry, and manner of exit (regular, irregular, state removal, natural death) of world leaders across nations from 1875 to 2010.

Regular Exit

The removal or retirement of a political executive according to the prevailing constitutional rules, established institutional provisions, conventions, term limits, or democratic elections of a country.

Irregular Exit

The termination of a political leader's rule through extra-institutional, non-constitutional, or violent actions, such as coups, revolts, or assassinations.

Standardized Precipitation-Evapotranspiration Index (SPEI)

A multiscalar drought metric that combines precipitation and potential evapotranspiration (PET) data to capture the soil water balance and quantify drought conditions relative to local climatological norms.

Competing-Risks Model (Fine and Gray)

A survival analysis regression model utilizing subdistribution hazards to estimate event probabilities when multiple distinct, mutually exclusive failure types (such as regular vs. irregular political exit) prevent one another from occurring.

Cumulative Incidence Function (CIF)

A statistical function used in competing-risks frameworks that calculates the absolute probability of a specific event occurring over time while properly accounting for the occurrence of competing events.

Polity IV Measure

A political science index scoring national regime authority on an institutional scale ranging from autocracies to anocracies to full democracies.
