How climate policy commitments influence energy systems and the economies of US states - Nature Communications
Abstract In the United States, state governments have been the locus of action for addressing climate change. However, the lack of a holistic measure of state climate policy has prevented a comprehensive assessment of state policies’ effectiveness. Here, we assemble information from 25 individual policies to develop an aggregate index of state climate policies from 2000-2020. The climate policy index highlights variation between states which is difficult to assess in single policy studies.
Change in US state-level public opinion about climate change: 2008-2020
Americans’ views about global warming have been studied extensively over the past several decades [1–9]. During this time, Americans’ climate opinions have changed dramatically, with the views of Democrats strengthening considerably, and the views of Republicans showing a less consistent trend [9–11]. Studies have found increasing issue salience, especially in recent years, along with growing partisanship and political polarization [9, 12–14].
The durable, bipartisan effects of emphasizing the cost savings of renewable energy
We are pleased to announce the publication of a new¬Ýarticle, ‚ÄúThe durable, bipartisan effects of emphasizing the cost savings of renewable energy‚Äù in¬ÝNature Energy. In this study, we tested different renewable energy messages to assess their effects on public beliefs about the benefits of renewable energy and support for renewable energy policies, and how long those effects lasted over time.
Protesters want justice - including on social, economic and climate demands
The United States is facing several crises: the coronavirus pandemic; widespread unemployment; rampant inequality, particularly along racial lines; police brutality - and a growing climate crisis. With hundreds of thousands of Americans in the streets protesting over the past two weeks, it's clear that many people are unhappy with how their leaders are handling these crises.
Analysis | Protesters want justice — including on social, economic and climate demands
The United States is facing several crises: the coronavirus pandemic; widespread unemployment; rampant inequality, particularly along racial lines; police brutality — and a growing climate crisis. With hundreds of thousands of Americans in the streets protesting over the past two weeks, it’s clear that many people are unhappy with how their leaders are handling these crises.
Combining climate, economic, and social policy builds public support for climate action in the US
Despite the gravity of the climate threat, governments around the world have struggled to pass and implement climate policies. Today, politicians and advocates are championing a new idea: linking climate policy to other economic and social reforms. Will this approach generate greater public support for climate action? Here, we test this coalition-building strategy.
Which racial/ethnic groups care most about climate change?
Climate change disproportionately affects members of disadvantaged communities and groups who face socioeconomic inequalities, including many people of color. As the United States becomes more racially and ethnically diverse, promoting public engagement with climate change across diverse audiences is becoming increasingly important.
Degrees of Change
Key Findings Americans today are more certain about the existence of climate change, and they are more likely to perceive it as serious and caused by human activities than in 2011. These changes have varied significantly by partisanship. Democrats are increasingly certain about the existence, seriousness, and human-caused nature of climate change. Republicans are increasingly certain about its existence and seriousness, but no more likely to think it is caused by human activity.
The development of partisan polarization over the Green New Deal
Abstract In early 2019, a US climate change and economic renewal policy proposal called the Green New Deal (GND)1 rose from obscurity to national prominence in just four months. This situation created a natural field experiment in which to study the emergence of partisan polarization. Here, we report findings from two nationally representative surveys of registered US voters that measured familiarity with and support for the GND shortly before and after the issue entered the national spotlight.
Analysis | What comes next in Trump’s fight with California about auto emissions standards
President Trump plans to revoke California’s authority to regulate greenhouse gas emissions from cars. This move — paired with Trump’s effort to roll back federal greenhouse gas standards — could have major repercussions. Transportation accounts for one-third of the United States’ carbon dioxide emissions, so this battle between Trump and California could have major consequences for climate change. Here’s what you need to know and what could happen next. What is the California waiver?
A Growing Majority of Americans Think Global Warming is Happening and are Worried
Data from our Climate Change in the American Mind surveys show that, over the past five years, the proportion of Americans who think global warming is happening and who worry about it has increased sharply. During this time, Americans have become increasingly convinced that global warming is happening (+11 percentage points), is human-caused (+15), and that most scientists agree it is happening (+15).
