Hot Topic: Food futures. Mr. Trump’s EPA unveiled plans this week to revoke the landmark “endangerment finding”—the key scientific rule that gives the government the power to limit fossil fuel pollution. The move amounts to an outright rejection of the scientific consensus that greenhouse gases endanger public health, and it threatens to erase emissions limits from cars, power plants, and other pollution sources.
A 45-day public comment period on the proposal will soon begin. Once the EPA issues the final rule, lawsuits are certain to follow—and the matter will ultimately be decided in court. If ultimately upheld, it could make it significantly harder for future administrations to limit the burning of coal, oil and gas.
Against this backdrop of regulatory retreat, new research and international reports make clear: climate change is fueling a global food crisis, with droughts, heatwaves, and rising prices undermining nutrition and pushing millions further into hunger.
A study released ahead of this week’s UN Food Systems Summit links climate-driven droughts, floods, and heatwaves to rising global food prices. In just one recent example, persistent droughts followed by record heat across Ghana and the Ivory Coast—where 60% of the world’s cocoa is grown—recently triggered a staggering 300% spike in cocoa prices.
The UN’s State of Food Security and Nutrition in the World report for 2025, released this week, underscores the scale of the crisis. Since 2020, food price inflation has outpaced overall inflation in nearly every region. From 2019 to 2025, 139 countries experienced food price increases above 25%, with 49 seeing spikes of more than 50%. And the report makes clear: climate change is now a central driver of rising prices and worsening hunger, especially for the world’s most vulnerable.
The UN reports 66.6% of Africa’s population—more than double the global average of 31.9%—cannot afford a healthy diet. And the International Energy Agency estimates that despite progress, 2 billion people globally still rely on polluting fuels for cooking, contributing to 815,000 premature deaths each year.
Adding to these threats, new research from the Society for Experimental Biology finds that rising temperatures and CO₂ levels are eroding the nutritional quality of leafy greens like spinach, kale, and arugula—reducing their content of vital nutrients like iron, magnesium, and protein, especially when increased heat and CO₂ levels are combined.
Last year, the IEA rallied governments and funders to pledge $2.2 billion for clean cooking in Africa, marking an unprecedented global push to accelerate progress. Yet in many other cases, interventions remain largely underfunded and politically sidelined. As the U.S. retreats, climate shocks intensify and inequality deepens, inaction is becoming its own form of policy—one with consequences far beyond the dinner table.
Human Health
Preliminary research indicates that rising atmospheric CO₂ and higher temperatures significantly reduce the nutritional quality of leafy vegetables, with serious implications for human nutrition and health. (Phys.org)
A new study warns that climate change is increasing the risk of pandemics by making 9% of Earth’s land—home to 130 million people—highly vulnerable to outbreaks of zoonotic diseases like Ebola, Zika, and SARS. (Carbon Brief)
A study of 11 years of California emergency room data shows that as temperatures rise, ER visits increase—especially among children under five, who visit at higher rates than any other age group. (The Washington Post)
Planetary Health
A new study finds that wildfires have surpassed logging and agriculture as the top threat to forests’ ability to absorb carbon, with global forests soaking up just a quarter as much CO₂ in 2023 and 2024 as they did in the early 2000s. (The New York Times)
A separate new study finds that extreme fire weather nearly doubled the amount of forest canopy lost to fire worldwide in 2023 and 2024, the hottest years on record, with North American forests losing nearly four times as much as in previous decades. (The New York Times)
New research analyzing two decades of NASA satellite data reveals that Earth’s continents are losing fresh water at an unprecedented rate due to climate change and poor groundwater management, with 75% of the world’s population living in areas facing growing risks to water and food security.

Equity
A new study links extreme weather with rising food costs and warns that climate-fueled price shocks are exacerbating global health and equity disparities, with the poorest communities facing heightened risks of malnutrition and food insecurity. (The Guardian)
Despite global progress, four in five households in sub-Saharan Africa still cook with polluting fuels, contributing to 815,000 premature deaths each year—a crisis now targeted by new government policies and $2.2 billion in investments coordinated by the International Energy Agency. (Axios)
Despite the Basel Convention classifying mixed plastic waste as hazardous, wealthy nations continue to export plastic-laden ‘refuse-derived fuel‘ (RDF) to poorer countries to be burned—exploiting legal loopholes to offload toxic, climate-harming waste in what environmental advocates call “waste colonialism.” (Grist)
NOAA and the National Weather Service warn that Southern Black communities in the U.S. face nearly double the flood exposure of other groups due to racial and infrastructural inequities that leave them vulnerable to growing flood threats. (Capital B)
Politics & Economy
Administration Watch:
- Mr. Trump’s EPA is proposing to revoke the landmark “endangerment finding” that underpins federal greenhouse gas regulations—marking a shift toward outright climate science denial and threatening to dismantle emissions rules for cars, power plants, and other major polluters. (The New York Times)
- The Trump administration has backed away from plans to abolish FEMA outright, instead moving toward a “rebranding” that emphasizes state rather than federal disaster response leadership. (The Washington Post)
- The Trump administration has suspended work on a groundbreaking NOAA tool that would have predicted how climate change will intensify rainfall across the U.S., leaving communities without vital data as storms and flood risks intensify. (The Washington Post)
- The EPA eliminated its Office of Research and Development, which studied hazardous chemicals, environmental threats, and their impact on humans and the environment. (The Washington Post)
- The EPA has delayed enforcement of a Biden-era rule to limit methane emissions from oil and gas drilling, granting companies another 18 months to comply as they consider eliminating the rule entirely. (The Hill)
