If the world continues on its current trends, it will mean species suicide. It’s imperative that we take the blinders off and face these crises openly and honestly.
On U.S. President Donald Trump’s first day back in office, he pulled the U.S. out of the Paris climate accords again, halted leasing and permitting for offshore wind energy projects, and signed executive orders promoting fossil fuel development. The previous Trump administration rolled back more than 100 environmental regulations. It seems likely he’ll now continue this process with even more vehemence.
The Intergovernmental Panel on Climate Change (IPCC) released a report in 2018, which found that “global warming is likely to reach 1.5°C between 2030 and 2052 if it continues to increase at the current rate.” A 1.5°C rise in temperature will render the Earth virtually uninhabitable.
We are already somewhere between 0.8°C and 1.2°C above pre-industrial levels and trending in the wrong direction. 2024 was the warmest year on record, surpassing 2023, the previous record holder.
Former Executive Secretary of the United Nations Framework Convention on Climate Change Christiana Figueres (writing with co-author Tom Rivett-Carnac) once predicted how the world might look in 2050:
In many places around the world, the air is hot, heavy, and depending on the day, clogged with particulate pollution. Your eyes often water. Your cough never seems to disappear. You can no longer simply walk out your front door and breathe fresh air. Instead, before opening doors or windows in the morning, you check your phone to see what the air quality will be. Everything might look fine—sunny and clear—but you know better. When storms and heatwaves overlap and cluster, the air pollution and intensified surface ozone levels can make it dangerous to go outside without a specially designed face mask (which only some can afford).
Current government policy is to accelerate this threat.
Partisan rhetoric can give the impression that scientists are divided on this issue. The debate around climate change is usually a debate about whether climate change exists. Not what to do about it.
According to a 2021 study by Cornell University, there’s 99.9% agreement among scientists that climate change is caused by humans. You won’t find that level of consensus among scientists about gravity.
The right wing knows this perfectly well. Donald Trump, for instance, applied for a permit in 2016 to build a coastal protection wall to prevent erosion due to rising seas levels at one of his seaside golf courses. The permit application explicitly mentioned global warming.
There used to be a right-wing opposition to climate change. In the early 2000s, Newt Gingrich was proposing measures to deal with climate change. Then, the fossil fuel industry came in and essentially remade the Republican Party in their image.
A famous study from 2013 by the Investigative Reporting Workshop at American University documented how David and Charles Koch, through their think tank Americans for Prosperity, got members of Congress to sign a pledge to vote against virtually any climate legislation which would regulate businesses. In 2013, more than 400 current officeholders had signed this pledge.
This was a major turning point in the fight against climate change. From 2003 to 2021, the number of Republicans who believed global warming was caused by human activity dropped from 65% to 32%.
According to the U.N., between 3.3 and 3.6 billion people live in contexts that are highly vulnerable to climate change. As ecological catastrophes become more and more common and large areas of the globe become uninhabitable, there’s going to be greater mass migration to the First World than we’ve ever seen. The instruments of separation (walls, cages, border patrols) have already been erected, but they won’t be able to stop it. People will find a way.
Failure to curb the use of fossil fuels and halt carbon emissions will mean crop shortages, heatwaves, droughts and floods, even more devastating hurricanes, rising sea levels, and wildfires. There is growing concern among experts that thawing permafrost could release viruses which have been dormant for thousands of years, potentially causing pandemics worse than Covid-19.
Are we in the final century of human civilization? It’s very possible. This is the generation that will decide whether humankind continues. If the world continues on its current trends, it will mean species suicide. It’s imperative that we take the blinders off and face these crises openly and honestly. By the time they become too severe to ignore, it will be too late to do anything.
"While a single year above 1.5°C of warming does not indicate that the long-term temperature goals of the Paris agreement are out of reach, it is a wake-up call," wrote the secretary-general of the World Meteorological Organization.
A report released by the World Meteorological Organization on Tuesday found that not only was 2024 the warmest year in a 175-year observational period, reaching a global surface temperature of roughly 1.55°C above the preindustrial average for the first time, but each of the past 10 years was also individually the 10 warmest on record.
"That's never happened before," Chris Hewitt, the director of the WMO's climate services division, of the clustering of the 10 warmest years all in the most recent decade, toldThe New York Times.
All told, the agency's State of the Global Climate 2024adds new details to the public's understanding of a planet that is getting steadily warmer thanks to human-caused greenhouse gas emissions.
2024 clearly surpassed 2023 in terms of global surface temperature. 2023 recorded a temperature of 1.45°C above the average for the years 1850-1900, which is used to represent preindustrial conditions, according to the report.
The report from the WMO, a United Nations agency, includes "the latest science-based update" on key climate indicators, such as atmospheric carbon dioxide, ocean heat content, and glacier mass balance. Many of these sections report grim milestones.
In 2023, the atmospheric concentration of carbon dioxide reached the highest levels in the last 800,000 years, for example, and in 2024, ocean heat content reached the highest level recorded in the over half-century observational period, topping the previous heat record that was set in 2023.
As of 2023, two other greenhouse gases, methane and nitrous oxide, also reached levels unseen in the last 800,000 years.
"Over the course of 2024, our oceans continued to warm, sea levels continued to rise, and acidification increased. The frozen parts of Earth's surface, known as the cryosphere, are melting at an alarming rate: glaciers continue to retreat, and Antarctic sea ice reached the second-lowest extent ever recorded. Meanwhile, extreme weather continues to have devastating consequences around the world," wrote WMO Secretary-General Celeste Saulo in the introduction to the report, which drew its findings from data drawn from dozens of institutions around the world.
"While a single year above 1.5°C of warming does not indicate that the long-term temperature goals of the Paris agreement are out of reach, it is a wake-up call that we are increasing the risks to our lives, economies and the planet," wrote Saulo.
In 2015, 196 party countries signed on to the agreement to pursue efforts "to limit the temperature increase to 1.5°C above preindustrial levels." According to the United Nations, going above 1.5ºC on an annual or monthly basis doesn't constitute failure to reach the agreement's goal, which refers to temperature rise over decades.
There are multiple methods that aim to measure potential breaches of 1.5°C over the long term, according to the report. The "best estimates" of current global warming based on three different approaches put global temperatures somewhere between 1.34°C and 1.41°C compared to the pre-industrial period.
The report also details the damage brought on by a number of extreme weather events last year, including Hurricanes Helene and Milton in the United States, and Cyclone Chido, which impacted the French territory of Mayotte.
While the developed world is rapidly changing its relationship with the rest of the world, the price of not providing climate finance will be economic losses, health impacts, increased disaster costs, food insecurity, biodiversity loss, and infrastructural damage.
The global commitment to fair climate finance is at a crossroads. COP29 concluded with a disappointing New Collective Quantified Goal on Climate Finance, or NCQG, leaving developing nations at risk of being left behind. With the U.S. withdrawing from the Paris agreement and slashing development aid, prospects for more ambitious fair climate finance are disappearing out of sight. Decisions like these not only threaten global cooperation on climate change but will also fail to meet its core purpose in supporting the most affected communities in adapting to and mitigating climate change. Now, more than ever, fair and equitable climate finance—such as increased grant-based funding and debt relief—is critical.
In Africa, the impacts of climate change are stark and undeniable. Extreme weather events on the continent surged from 85 in the 1970s to over 540 between 2010 and 2019, causing over 730,000 deaths and $38.5 billion in damages. The increasing frequency and severity of floods, droughts, and storms are threatening food security, displacing populations, and putting immense stress on water resources. According to the World Bank, climate change could push up to 118 million extremely poor people in Africa into abject poverty by 2030 as drought, floods, and extreme heat intensify. A stark reality that underscores the urgent need for robust climate finance to implement adaptation and mitigation strategies to safeguard and secure the continent's future.
Without stronger commitments to public grants and additional funding, developing countries risk falling into a cycle of debt that hinders climate action.
At the same time, climate response remains critically underfunded in Africa. From the figures released by the Climate Policy Initiative, the continent will need approximately $2.8 trillion between 2020 and 2030 to implement its Nationally Determined Contributions (NDCs) under the Paris agreement. However, current annual climate finance flows to Africa are only $30 billion, exposing a significant funding gap for climate adaptation and mitigation strategies.
COP29's main objective was to deliver on a finance goal that would see the world off the tipping point. However, after two weeks of nearly failed climate diplomacy, negotiators agreed to a disappointing $300 billion annually by 2035. This amount falls short of the $1.3 trillion per year figure, supported by the Needs Determinant Report, that many developing countries had advocated for.
Nevertheless, the Baku to Belem Roadmap has been developed to address the climate finance gap. This framework, set to be finalized at COP30 in Brazil, offers a crucial opportunity to refine finance mechanisms to effectively and equitably meet the needs of developing countries.
Beyond the insufficient funding, the NCQG lacks a strong commitment to equity, a key principle of the Paris agreement. The principle of Common but Differentiated Responsibilities (CBDR) emphasizes that developed countries should bear a greater share of the financial burden. However, the NCQG merely states that developed nations would "take the lead" in mobilizing $300 billion, reflecting a lack of firm commitment.
A major concern is the climate debt trap for developing nations. Much of the climate finance provided is in the form of loans rather than grants, worsening existing debt burdens and limiting investments in sustainable development. Without stronger commitments to public grants and additional funding, developing countries risk falling into a cycle of debt that hinders climate action.
To ensure COP29's finance outcomes do not leave the Global South behind, several actions are needed.
Firstly, debt relief is crucial. Approximately 60% of low-income countries are already in or near debt distress. Between 2016 and 2020, 72% of climate finance to developing nations was in loans, while only 26% was in grants. Reducing debt burdens would allow developing countries to allocate more resources to climate projects, improve fiscal stability, and attract additional investments.
Similarly, given the mounting climate finance debts in low-income developing countries, increased grant-based financing for climate action is needed. In 2022, developed countries provided around $115.9 billion in climate finance to developing countries, but a significant portion was in the form of loans. Heavy reliance on debt-based financing exacerbates financial burdens on these nations. Grant-based finance, on the other hand, aligns with equity principles and ensures that funding effectively supports adaptation and mitigation.
Another potential path is leveraging private sector investment. The private sector plays an essential role in climate finance. However, its involvement often prioritizes profit over genuine climate benefits. Strategies must ensure that private investments align with climate justice principles. To address this, approaches are needed such as those used by Bill and Melinda Gates.
Lastly, implementing robust governance and transparent mechanisms is critical. This includes developing detailed reporting templates, public participation in decision-making, and clear monitoring systems to track climate finance flows and prevent double counting.
While the developed world is rapidly changing its relationship with the rest of the world from aid to trade, the price of not providing equitable, grant-based, public climate finance will be economic losses, health impacts, increased disaster costs, food insecurity, biodiversity loss, and infrastructural damage. Quite simply, taking the equity conditions into account is the way forward if we are to ensure that the outcomes of COP29 leave no low-income developing nation in the Global South behind.
