UN climate negotiations end on shaky geopolitical ground, but I see reasons for hope
Shannon Gibson, USC Dornsife College of Letters, Arts and Sciences
The 2024 United Nations climate talks wrapped up two days late, with an ending fitting that of a geopolitical reality TV show, complete with walkouts and recriminations.
Countries agreed on a new climate finance target on Nov. 24, 2024, promising to provide at least US$300 billion annually by 2035 to help developing countries build clean energy systems. But it was far less than the $1.3 trillion vulnerable countries were calling for.
The conference also delayed a debate over how to move forward on a 2023 agreement for all countries to contribute to “transitioning away from fossil fuels” and to submit climate pledges aligned with the 1.5C limit.
Some people may be ready to write the epitaph for global progress against climate change. But as someone who teaches global environmental politics and has followed international climate talks for years, I see both practical and moral reasons to remain hopeful.
The battle to keep the 1.5 C goal alive
In 2015, the world’s nations agreed as part of the Paris climate accord to limit global warming to 2 degrees Celsius (3.6 degrees Fahrenheit), with an aspirational target of 1.5 C (2.7 F). This target is important, but sometimes confusing. It is rooted in science, but it is not a singular “tipping point.”
As the planet warms beyond 1.5 C, multiple large-scale climate shifts will become more likely.
Ocean circulation is already slowing, coral reefs face increasingly common mass bleaching events as the oceans heat up, and Arctic permafrost is thawing, releasing greenhouse gases that further fuel climate change. Rising temperatures are also fueling increasingly frequent and more damaging heat waves, droughts, wildfires and flooding that put human lives and livelihoods at risk.

Recognizing these risks, the Paris Agreement was widely heralded, and many countries have made progress in lowering their emissions in the decade since. However, not all countries are pulling their weight.
In 2023, the U.N. acknowledged that the countries’ current commitments for addressing climate change, known as nationally determined contributions, or NDCs, would still result in a catastrophic 2.5 C to 2.9 C (4.5 F to 5.2 F) of warming by 2100.
The World Meteorological Organization issued a “red alert” in November 2024 that the world is on track to overshoot the 1.5 C goal this year. It notes that this overshoot can be temporary – if countries take greater action.
How the world can still meet the Paris goals
Countries can still turn the tide on climate change.
The outcomes of the 2023 climate talks provided a road map for countries to increase their efforts toward net-zero emissions:
- Triple renewable energy capacity globally.
- Accelerate a phasedown of coal power.
- Transition away from fossil fuels.
- Accelerate zero-emissions and low-emissions technologies.
- Cut methane and other noncarbon dioxide emissions.
- Reduce emissions from road transport.
- Phase out inefficient fossil fuel subsidies.
Many countries are making progress on this transition.
Among developed countries, Norway is on track to phase out of fossil fuel vehicle sales in 2025. China has become a leader in renewable energy. It pledged in 2020 to double its renewable energy capacity by 2030, and, thanks to solar power deployment, it expects to complete that goal in half the time.
Other nations, including the U.K., Greece and Denmark, have embarked on major efforts to scale down coal power, with Portugal being the first to hit zero coal.
An important mechanism of the Paris Agreement is the expectation that countries will ratchet up their commitments every five years. The deadline for these new climate goals is early 2025, and some countries have gotten a head start.
Brazil announced its new climate commitments during the climate conference, pledging to reduce emissions 67% by 2035. The United Arab Emirates submitted a commitment to reduce its emissions by 47% compared with its 2019 baseline emissions. Other countries signaled their intentions in high-level statements. Belgium announced a doubling of its climate finance contribution.
These new announcements are a good sign of continued global support for the Paris Agreement goals.
Additionally, the conference made progress on agreements to reduce non-CO₂ emissions, namely methane, nitrous oxide and hydrofluorocarbons – also known as climate change “super pollutants” because of their extreme global warming potential.
Why the Paris Agreement will survive a second Trump presidency
There is no doubt that Donald Trump returning as U.S. president will pose significant roadblocks to efforts to slow climate change. As a candidate, he talked about throttling back U.S. efforts, including cutting funding for clean energy and eliminating regulations on the fossil fuel industry.
But efforts to deal with climate change are bigger than one person or even one country.
While Trump has declared that he will pull the U.S. out of the international Paris Agreement again, influential people are advising him to reconsider. Exxon Mobil CEO Darren Woods argued that a U.S. withdrawal would leave a hole at the global negotiating table.
Even if Trump does pull the U.S. out of the treaty, which he can do after a one-year waiting period, that doesn’t mean pro-climate actions in the U.S. will simply stop or that the agreement will fall apart.
There are commonsense business reasons to push climate efforts forward, starting with the fact that clean energy is now cheaper than fossil fuels in much of the world. Nearly 1 in 5 vehicles sold in 2023 globally were electric. In the U.S., heat pump sales are beating gas furnaces for the third straight year. https://ourworldindata.org/grapher/levelized-cost-of-energy?tab=chart
A withdrawal from the Paris Agreement also does not prevent states and cities from continuing their progress against climate change.
In fact, after Trump announced he would withdraw the U.S. from the agreement in 2017, several U.S. states doubled down on their climate commitments. Hawaii, for example, passed legislation to be “Paris compliant” and get to net-negative emissions, meaning it will sequester more emissions than it emits.
California continues to report falling emissions even with a growing economy. The state sued several large oil and gas companies for deceiving the public about climate change.
Moreover, a U.S. retreat from the Paris Agreement would not be an embargo on individual actions. Engineers and scientists will continue to create innovative technology to reduce emissions and slow climate change, and corporations will reap the economic benefits of energy efficiency and clean energy market leadership.
This acknowledgment has given rise to calls for a blend of optimism and pragmatism.
Looking ahead to 2025
Next year’s COP30, to be held in Brazil, is important because countries face a deadline for setting new targets. Overall, their current policies still fall short of the 1.5 C goal.
Calls for greater commitments are not just optimistic, they are economically and morally compelling.
For one, the future cost of inaction now is greater than the cost of action, so concerted decisions to delay emissions cuts now will only harm countries in the future.
Morally, the international community has a responsibility to mitigate suffering. This is the very nature of long-held international norms and laws, such as the “responsibility to protect,” and reiterated in Pope Francis’ calls for global environmental responsibility.
While the climate will breach the 1.5 C warming limit, every fraction of a degree matters. I believe it is crucial that countries, states, business leaders and people everywhere continue the shift toward cleaner energy to minimize the impact.

Food Truths
The Truth About the “Chemical” in McDonald’s Burger Buns: Should Consumers Be Concerned?
What’s in the Burger Buns:The “yoga mat chemical” controversy changed how consumers view food additives. Here’s what azodicarbonamide is, why McDonald’s removed it, and what the science actually says.
For years, headlines and social media posts have warned consumers about a so-called “yoga mat chemical” found in hamburger buns served by major fast-food chains. The claims sparked widespread concern, prompted petitions, and eventually led several restaurant companies—including McDonald’s—to change their recipes.
But what was the chemical, and is there actually a health risk today?
What Was the Controversial Ingredient?
The ingredient at the center of the controversy was azodicarbonamide (ADA), a chemical used as a dough conditioner. It helped improve the texture of bread, making dough easier to handle and producing softer, more consistent buns.
Ironically, the same compound is also used in manufacturing certain foamed plastics, including some yoga mats and shoe soles. That connection gave rise to the viral nickname, “the yoga mat chemical.”
While the comparison was technically accurate, it also lacked important context. Food-grade azodicarbonamide and industrial applications are very different, and many chemicals have multiple uses across industries.
Why Did People Become Concerned?
The concern wasn’t simply that ADA was used in food. Scientists focused on what happens during baking.
When bread is baked, most azodicarbonamide breaks down into other compounds. Some laboratory studies involving animals raised questions about one of these breakdown products, called semicarbazide (SEM), when administered in high doses.
Those findings prompted some countries to take a more cautious regulatory approach.
Why Is It Banned in Some Countries?
The European Union and Canada do not permit azodicarbonamide as a flour treatment agent. Their food safety policies often follow the precautionary principle, removing ingredients when safer alternatives exist or when scientific uncertainty remains.
In contrast, the U.S. Food and Drug Administration has determined that azodicarbonamide is safe when used within approved limits.
These differing regulations don’t necessarily mean one side believes the ingredient is dangerous while the other believes it is harmless. Instead, they reflect different philosophies about regulating food additives.
Does McDonald’s Still Use It?
No.
McDonald’s removed azodicarbonamide from its U.S. hamburger buns in 2014 following growing consumer demand for simpler ingredient lists.
Today’s buns no longer contain the ingredient, joining a broader trend among food manufacturers to eliminate additives that have become controversial with consumers.
Are There Other Ingredients Consumers Should Know About?
Modern commercial bread still contains ingredients designed to improve freshness, texture, and shelf life.
These may include:
- Calcium propionate to prevent mold
- Ascorbic acid (Vitamin C) as a dough conditioner
- Enzymes that improve consistency
- Emulsifiers that help maintain softness
These ingredients have been evaluated by food safety agencies and are generally recognized as safe when used according to regulations.
The Bigger Health Picture
Nutrition experts generally agree that focusing on one ingredient can distract from the larger issue.
The greatest health risks associated with fast food are more closely linked to:
- High sodium intake
- Excess saturated fat
- Added sugars
- Large portion sizes
- Frequent consumption of ultra-processed foods
An occasional fast-food meal is unlikely to determine someone’s long-term health. Overall dietary patterns, physical activity, sleep, and other lifestyle factors have a much greater impact.
Consumer Awareness Is Changing the Food Industry
Whether or not an ingredient poses a measurable health risk, public concern can influence corporate decisions.
Over the past decade, many food companies have reformulated products to remove controversial ingredients, reduce artificial additives, and simplify ingredient labels. In many cases, those changes have been driven as much by consumer preferences as by regulatory requirements.
The Bottom Line
The “yoga mat chemical” story captured public attention because it combined science, food safety, and memorable marketing. While azodicarbonamide was once used in some hamburger buns, including those supplied to McDonald’s, the company removed it from its U.S. buns years ago.
Current evidence suggests consumers are better served by paying attention to their overall diet rather than worrying about a single ingredient that has already disappeared from many products.
Being an informed consumer means looking beyond the headlines, understanding the science, and recognizing that nutrition is about the complete picture—not just one ingredient.

Millions of Eggs Recalled Over Possible Salmonella Risk: What Consumers Need to Know
A major egg recall is affecting nearly 1.6 million dozen eggs sold under several popular brands. Here’s how to determine if your eggs are included and what steps to take if they are.
News You Can Use This Moment!
Consumers are being urged to check their refrigerators after a major recall involving nearly 1.6 million dozen shell eggs due to the potential presence of Salmonella Enteritidis, a bacterium that can cause serious foodborne illness.
The voluntary recall, announced by Midwest Poultry Services, L.P., affects white shell eggs and brown cage-free eggs produced at two Texas farms and distributed between June 6 and July 3, 2026. According to the U.S. Food and Drug Administration (FDA), the eggs were sold through grocery stores and foodservice distributors in Texas, Louisiana, Oklahoma, Arkansas, Mississippi, and New Mexico.
What Brands Are Included?
The recalled eggs were sold under several familiar brand names, including:
- Kroger
- Simple Truth
- Brookshire’s
- Country Morning
- Sunups
Not every carton under these brands is affected. Consumers should look for:
- Plant Code: P-1950 or 0840962
- Julian Dates: 157 through 184
- Best By/Sell By Dates: July 20, 2026, through August 17, 2026
Why the Recall Matters
Salmonella can cause symptoms including:
- Diarrhea
- Fever
- Stomach cramps
- Nausea
- Vomiting
Symptoms typically begin 12 to 72 hours after eating contaminated food and usually last four to seven days. While many healthy adults recover without treatment, infections can become severe in young children, older adults, pregnant women, and people with weakened immune systems.
The FDA and the Centers for Disease Control and Prevention (CDC) are investigating a multistate outbreak involving 98 confirmed illnesses across 17 states, resulting in 26 hospitalizations. No deaths have been reported. Investigators say the recalled eggs are linked to part of the outbreak, although they do not account for every reported illness.
What Should You Do?
If you have eggs matching the recalled codes:
- Do not eat them.
- Return them to the store for a refund or dispose of them safely.
- Wash your hands thoroughly after handling the carton.
- Clean and sanitize any refrigerator shelves, containers, or kitchen surfaces the eggs may have touched.
If you have already eaten the eggs and develop symptoms of Salmonella infection, contact your healthcare provider, especially if symptoms are severe or persist.
Are Arizona Consumers Affected?
The recalled products were officially distributed in six states, and Arizona is not listed among the primary distribution states. However, because food products can move through wholesalers, travelers, or secondary retailers, Arizona consumers who recently purchased eggs while traveling—or who received eggs from family or friends in affected states—should still check the carton codes.
The Bottom Line
Food recalls are an important part of protecting public health. Taking a few moments to inspect the eggs in your refrigerator could help prevent a serious illness. If your carton matches the recalled plant codes and date range, don’t take the risk—return it or throw it away.
STM Daily News will continue to monitor this developing story and provide updates as additional information becomes available.
