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.

Travel Advisory
Traveling to Mexico this spring? Here’s what to know about current advisories
Traveling to Mexico this spring? Visitors should be aware of state-specific travel advisories, as safety concerns in one region do not affect major resort areas like Cancun and Los Cabos, currently rated Level 2, which encourages increased caution. Monitoring official updates is essential for informed travel decisions amidst evolving conditions.

Traveling to Mexico this spring? Here’s what to know about current advisories
(Tiffany Miller for ALG Vacations) For some travelers counting down to spring break, recent headlines about violence in parts of Mexico have sparked a new question: Should I cancel my trip? Travel advisors say they are seeing a surge in calls and emails from clients trying to determine whether developments in one region affect major resort areas elsewhere.
The questions follow several days of unrest in parts of Mexico after security operations targeting organized crime leaders prompted temporary flight disruptions and shelter-in-place guidance for U.S. government personnel in areas including Puerto Vallarta and Guadalajara. In this article, ALG Vacations explains what current travel advisories mean for spring break travelers heading to Mexico.
The U.S. State Department evaluates Mexico state by state, not as a single destination, and advisory levels vary by region. Many major beach destinations, including Cancun, Riviera Maya, Tulum and Los Cabos, are currently under a Level 2 advisory, which encourages travelers to exercise increased caution. It does not discourage travel.
Part of the confusion stems from geography. Puerto Vallarta, on the Pacific coast, is roughly 1,300 miles from Cancun and the Riviera Maya on the Caribbean side, about the distance between New York and Miami. Because advisories are assigned state by state, developments in one region do not automatically alter another.
In recent days, that uncertainty has translated into additional inquiries about whether specific resort areas are experiencing disruptions. U.S. Embassy security alerts issued this week indicate that temporary shelter-in-place guidance affecting Puerto Vallarta was lifted and that flight operations resumed. The advisory level for the Mexican state of Quintana Roo remains unchanged.
Some clients are asking about alternatives, advisors say, but many are continuing with their plans after reviewing official updates. Travel patterns often shift in response to breaking headlines, they add, before stabilizing as clearer information becomes available.
The State Department assigns travel advisories on a four-tier scale ranging from Level 1, exercise normal precautions, to Level 4, do not travel. While Level 2 encourages increased awareness, Level 3 and Level 4 carry stronger language discouraging or restricting travel.
Advisories are reviewed regularly and can be updated as conditions evolve. The State Department’s Mexico advisory page breaks down conditions by state, reflecting the country’s federal structure rather than issuing a single national designation. Travelers can also enroll in the State Department’s Smart Traveler Enrollment Program, which provides real-time security updates and allows U.S. officials to contact citizens in an emergency.
Embassy notices state that airports, hotels and tourism services in Quintana Roo are operating normally. Security conditions across Mexico vary widely by state, with some regions carrying higher advisories and others designated Level 1. Most destinations popular with U.S. travelers are currently classified as Level 2.
As spring break approaches, advisors say informed decision-making depends on reviewing the advisories assigned to a specific destination and monitoring official updates, rather than reacting to national headlines alone. Travel decisions ultimately depend on individual comfort levels, they add, but advisory levels are assigned regionally and should be evaluated accordingly.

With the Olympic torch extinguished in Paris, all eyes are turning to Los Angeles for the 2028 Olympics.
The host city has promised that the next Summer Games will be “car-free.”
For people who know Los Angeles, this seems overly optimistic. The car remains king in LA, despite growing public transit options.
When LA hosted the Games in 1932, it had an extensive public transportation system, with buses and an extensive network of electric streetcars. Today, the trolleys are long gone; riders say city buses don’t come on schedule, and bus stops are dirty. What happened?
This question fascinates me because I am a business professor who studies why society abandons and then sometimes returns to certain technologies, such as vinyl records, landline phones and metal coins. The demise of electric streetcars in Los Angeles and attempts to bring them back today vividly demonstrate the costs and challenges of such revivals. https://www.youtube.com/embed/9X78ZqGyc5o?wmode=transparent&start=0 The 2028 Olympic Games will be held in existing sports venues around Los Angeles and are expected to host 15,000 athletes and over 1 million spectators.
Riding the Red and Yellow Cars
Transportation is a critical priority in any city, but especially so in Los Angeles, which has been a sprawling metropolis from the start.
In the early 1900s, railroad magnate Henry Huntington, who owned vast tracts of land around LA, started subdividing his holdings into small plots and building homes. In order to attract buyers, he also built a trolley system that whisked residents from outlying areas to jobs and shopping downtown.
By the 1930s, Los Angeles had a vibrant public transportation network, with over 1,000 miles of electric streetcar routes, operated by two companies: Pacific Electric Railway, with its “Red Cars,” and Los Angeles Railway, with its “Yellow Cars.”
The system wasn’t perfect by any means. Many people felt that streetcars were inconvenient and also unhealthy when they were jammed with riders. Moreover, streetcars were slow because they had to share the road with automobiles. As auto usage climbed and roads became congested, travel times increased.
Nonetheless, many Angelenos rode the streetcars – especially during World War II, when gasoline was rationed and automobile plants shifted to producing military vehicles. https://www.youtube.com/embed/AwKv3_WwD4o?wmode=transparent&start=0 In 1910, Los Angeles had a widely used local rail network, with over 1,200 miles (1,930 kilometers) of track. What happened?
Demise of public transit
The end of the war marked the end of the line for streetcars. The war effort had transformed oil, tire and car companies into behemoths, and these industries needed new buyers for goods from the massive factories they had built for military production. Civilians and returning soldiers were tired of rationing and war privations, and they wanted to spend money on goods such as cars.
After years of heavy usage during the war, Los Angeles’ streetcar system needed an expensive capital upgrade. But in the mid-1940s, most of the system was sold to a company called National City Lines, which was partly owned by the carmaker General Motors, the oil companies Standard Oil of California and Phillips Petroleum, and the Firestone tire company.
These powerful forces had no incentive to maintain or improve the old electric streetcar system. National City ripped up tracks and replaced the streetcars with buses that were built by General Motors, used Firestone tires and ran on gasoline.
There is a long-running academic debate over whether self-serving corporate interests purposely killed LA’s streetcar system. Some researchers argue that the system would have died on its own, like many other streetcar networks around the world.
The controversy even spilled over into pop culture in the 1988 movie “Who Framed Roger Rabbit,” which came down firmly on the conspiracy side.
What’s undisputed is that, starting in the mid-1940s, powerful social forces transformed Los Angeles so that commuters had only two choices: drive or take a public bus. As a result, LA became so choked with traffic that it often took hours to cross the city.
In 1990, the Los Angeles Times reported that people were putting refrigerators, desks and televisions in their cars to cope with getting stuck in horrendous traffic. A swath of movies, from “Falling Down” to “Clueless” to “La La Land,” have featured the next-level challenge of driving in LA.
Traffic was also a concern when LA hosted the 1984 Summer Games, but the Games went off smoothly. Organizers convinced over 1 million people to ride buses, and they got many trucks to drive during off-peak hours. The 2028 games, however, will have roughly 50% more athletes competing, which means thousands more coaches, family, friends and spectators. So simply dusting off plans from 40 years ago won’t work.
Olympic transportation plans
Today, Los Angeles is slowly rebuilding a more robust public transportation system. In addition to buses, it now has four light-rail lines – the new name for electric streetcars – and two subways. Many follow the same routes that electric trolleys once traveled. Rebuilding this network is costing the public billions, since the old system was completely dismantled.
Three key improvements are planned for the Olympics. First, LA’s airport terminals will be connected to the rail system. Second, the Los Angeles organizing committee is planning heavily on using buses to move people. It will do this by reassigning some lanes away from cars and making them available for 3,000 more buses, which will be borrowed from other locales.
Finally, there are plans to permanently increase bicycle lanes around the city. However, one major initiative, a bike path along the Los Angeles River, is still under an environmental review that may not be completed by 2028.
Car-free for 17 days
I expect that organizers will pull off a car-free Olympics, simply by making driving and parking conditions so awful during the Games that people are forced to take public transportation to sports venues around the city. After the Games end, however, most of LA is likely to quickly revert to its car-centric ways.
As Casey Wasserman, chair of the LA 2028 organizing committee, recently put it: “The unique thing about Olympic Games is for 17 days you can fix a lot of problems when you can set the rules – for traffic, for fans, for commerce – than you do on a normal day in Los Angeles.”
This article has been updated to indicate that Los Angeles has four light-rail lines.

Celebrating International Women’s Day!
International Women’s Day is celebrated globally on March 8th to honor women’s achievements and promote gender equality, originating from a 1908 march in New York for better rights.
Last Updated on March 7, 2026 by Daily News Staff
International Women’s Day is a global celebration that honors the achievements of women and highlights the progress still to be made in the fight for gender equality. On this day, people around the world come together to recognize the amazing contributions of women everywhere and to rally for greater gender equity in all areas of life.
The origins of International Women’s Day can be traced back to 1908, when 15,000 women marched through the streets of New York City to demand better working conditions and the right to vote. Since then, the celebration has grown to be an international event, with more than 100 countries recognizing the day. The United Nations even declared March 8th as International Women’s Day in 1975, to honor the struggles of women around the world.
This year’s International Women’s Day theme is #ChooseToChallenge, meaning that everyone is encouraged to call out gender bias and inequality when they see it. We’re also encouraged to celebrate women’s achievements, support each other, and take action for equality.
It’s important to recognize the progress we’ve made in terms of gender equality, but we still have a long way to go. International Women’s Day serves as a reminder that we must continue to fight for gender equality in all areas of life. Let’s use this day to honor the contributions of women around the world, and to continue the fight for a more equitable world.
