'Overwhelming' international support for more government action on environment, message-testing experiment finds

2021-03-01

(Press-News.org) With eight months to go before the UN Climate Change Conference (COP26), an international survey experiment has found evidence of "overwhelming" support across seven major countries for governments to "do more" to protect the environment.

The survey directly asks the public about policies they want to see backed by governments at COP26, when the UK and Italy will gather world leaders in Glasgow from 1 November to commit to urgent global climate action.

Researchers at the University of Cambridge worked with polling agency YouGov on a message-testing experiment involving 14,627 adults, with samples of around 2,000 each in Brazil, China, India, Indonesia, Poland, the UK and the US. Polling took place from 8th to 31st December 2020.

Participants were randomly assigned to read either one of four "treatment" texts about climate change - drafted to reflect current UN messaging, public health, social norms and patriotism - or a neutral text, unrelated to climate and used to test "baseline" support.

The participants were then asked if they agreed or disagreed with the statement that "all national governments should do more to protect the environment."

Baseline figures showed extremely high levels of support for government-led action. In six of these countries, at least nine out of ten participants agreed that governments should do more for the environment. In the US, the figure was three out of four (79%).

Compared to the baseline, exposure to one of the climate change texts led to a small but significant rise of about one or two percentage points on average. The figures ranged in the UK from 89-93%; as against 96-98% in Brazil, 91-95% in China, 92-97% in India, 99-100% in Indonesia, 91-94% in Poland and 76-79% in the USA.

Across all the responses, a majority (55%) of those who voted for former President Donald Trump in the November 2020 presidential elections agreed, although this figure was well below the 95% figure for those who voted for President Joe Biden. In the UK, 87% of Conservative supporters agreed, as compared to 97% of Labour supporters.

The issue may have even bridged the Brexit divide, with 96% of Remain voters and 86% of Leave voters in agreement on the need for more action.

Dr Lee de-Wit, a political psychologist at the University of Cambridge, said that the clearest evidence that a message had had an impact was in China, "where pollution is a daily reality for many". Support for more action rose from 91% to 95% among those that read about public health benefits of tackling climate change - a text that focused on air pollution.

"We live in a time of polarisation, and environmental issues have long embodied the political divisions in society. However, this may be changing. We can see an overwhelming consensus emerging for greater government-led action to protect the environment in major nations," de-Wit said.

"As we approach COP26, politicians the world over should take confidence from these findings. Voters across party lines want to see more government action. The time is now."

The survey also asked which policies governments should support at COP26. In each of these seven countries, baseline figures showed that at least 50% supported four policies.

The most popular on average was action "to protect and preserve" wildlife, marine life and plants; followed by a policy "to plant more trees to absorb the gases that cause climate change"; then spending more on developing clean technologies; then reducing "the production over thirty years of the gases that cause climate change."

Participants were also asked if they thought that businesses should be made "to pay for the damage they do when their activities contribute to climate change". In every country except China, baseline figures showed this to be a more popular policy than giving businesses a "fair timetable to stop activities that contribute to climate change." Across the seven countries, on average, 58% supported making businesses pay and 48% supported the timetable option.

In the United Kingdom, baseline figures for the most popular policies were protecting wildlife (84%), planting trees (81%) and spending more on clean technology (75%). Some 70% thought businesses should pay for environmental damage, while 67% supported reducing the production of greenhouse gases over 30 years. Baseline support for giving businesses a fair timetable to adapt stood at 55%. Only 5% believed that governments are "doing all they should".

In the United States, baseline figures were 70% for protecting wildlife, 67% for planting trees, and 60% for spending more on clean technology. Some 54% thought businesses should pay for environmental damage, while 51% supported reducing the production of greenhouse gases over 30 years. Baseline support for giving businesses a fair timetable to adapt stood at 42%. Only 10% believed that governments are "doing all they should".

Across the seven countries, for participants who had been exposed to one of the climate change texts, support for these policies rose by around 1% on average, which was not a significant change. However, support for tree-planting did rise significantly from a baseline of 73% to 76% for those exposed to the UN's current messaging, and to 75% for those who read a text on the public health benefits of tackling climate change.

De-Wit said that in the run up to COP26: "We face huge challenges protecting the environment, but global public opinion may no longer be chief among them."

Dr Sander van der Linden, Director of Cambridge's Social Decision-Making Lab, also involved in the research, added: "These survey results make it clear that irrespective of age, gender and nationality, citizens around the world want governments to do more to protect the environment."

Why COVID-19 vaccine distribution methods fall short and 3 ways to improve them

2021-03-01

BINGHAMTON, NY - Several proposals have emerged on how to distribute the COVID-19 vaccine, but they fall short in ensuring that the vaccine is distributed fairly. A team including Binghamton University professor Nicole Hassoun suggests three ways to more fairly and effectively distribute the vaccine so that people in poor countries get the vaccine as soon as possible. "Although many people in rich countries will receive a vaccine for COVID-19 this year, many people in poor countries will likely have to wait years to get one," said Hassoun. "Ethical vaccine allocation requires closing this gap and ensuring that everyone can access a vaccine ...

Financial incentives for hospitals boost rapid changes to opioid use disorder treatment

2021-03-01

PHILADELPHIA-- Hospital emergency departments (EDs) not only care for patients with overdose and other complications from opioid use, but they also serve as vital touch points to engage patients into longer-term treatment. After an overdose, patients are at risk for repeat overdose and death. Pennsylvania is unique in establishing a voluntary incentive program to improve the rate at which patients with opioid use disorder receive follow-up treatment after emergency department care. Evaluations of the program show that financial incentives are effective in producing rapid treatment innovations for opioid use disorder. In a study, researchers at the Perelman School of Medicine at ...

2021-03-01

Oak Brook, IL - The March edition of SLAS Discovery features the cover article, "Therapeutic and Vaccine Options for COVID-19: Status After 6 Months of the Disease Outbreak" by Christian Ogaugwu (Federal University Oye-Ekiti, Ekiti State, Nigeria ), Dawid Maciorowski, Subba Rao Durvasula, Ph.D., Ravi Durvasula, M.D., and Adinarayana Kunamneni, Ph.D. (Loyola University Medical Center, Maywood, IL, USA). This cover article focuses on the therapeutic and vaccine options available against the novel coronavirus, roughly six months after the outbreak; because the COVID-19-related death toll worldwide had reached 500,000 in six months (and ballooned to over 2,000,000 at the time of publishing) the importance of options to temper the disease cannot be overemphasized. The article ...

'Silent epidemic of grief' leaves bereaved and bereavement care practitioners struggling

2021-03-01

Major changes in bereavement care have occurred during the COVID-19 pandemic, amid a flood of demand for help from bereaved people, according to new research from the University of Cambridge. The first major study of pandemic-related changes in bereavement care has found that the switch to remote working has helped some services to reach out, but many practitioners feel they do not have capacity to meet people's needs. It is estimated that for every death, nine people are affected by bereavement. The scale of the impact of the COVID-19 pandemic on those ...

Sensing suns

2021-02-28

Red supergiants are a class of star that end their lives in supernova explosions. Their lifecycles are not fully understood, partly due to difficulties in measuring their temperatures. For the first time, astronomers develop an accurate method to determine the surface temperatures of red supergiants. Stars come in a wide range of sizes, masses and compositions. Our sun is considered a relatively small specimen, especially when compared to something like Betelgeuse which is known as a red supergiant. Red supergiants are stars over nine times the mass of our sun, and all this mass means that when they die they do so with extreme ferocity in an enormous explosion known as a supernova, in particular what is known as a Type-II supernova. Type II supernovae seed the cosmos with elements ...

When foams collapse (and when they don't)

2021-02-27

Tokyo, Japan - Researchers from Tokyo Metropolitan University have revealed how liquid foams collapse by observing individual collapse "events" with high-speed video microscopy. They found that cracks in films led to a receding liquid front which sweeps up the original film border, inverts its shape, and releases a droplet which hits and breaks other films. Their observations and physical model provide key insights into how to make foams more or less resistant to collapse. Understanding how foams collapse is serious business. Whether it's ensuring fire extinguishing foams stay long enough to put out flames, cleaning up toxic foams in seas and rivers, or simply getting the perfect rise on a cake, getting to grips with how foam materials collapse is vital to tailoring their properties, ...

Oahu marine protected areas offer limited protection of coral reef herbivorous fishes

2021-02-26

Marine protected areas (MPAs) around O?ahu do not adequately protect populations of herbivorous reef fishes that eat algae on coral reefs. That is the primary conclusion of a study published in Coral Reefs by researchers from the University of Hawai?i at Mānoa School of Ocean and Earth Science and Technology (SOEST). There are over 20 species of herbivorous fishes and ten species of herbivorous urchins commonly observed on Hawaiian reefs. These species eat algae that grows on reefs, a process called herbivory, that contributes to the resilience of coral reefs by preventing algae dominance that can lead to overgrowth of corals. The team of researchers found that of the four marine protected areas around O?ahu they assessed in the study, ...
