Donald Trump Is Rolling Back Climate Protections: Should The World Be Concerned?

On 12 February 2026, the White House announced the formal reversal of the 2009 “endangerment finding”, an Obama-era scientific ruling declaring that certain greenhouse gases — gases that trap heat in the atmosphere — pose a threat to human health. Greenhouse gases include carbon dioxide (CO₂) from burning fossil fuels, methane from landfills and agriculture, and other planet-warming gases. These gases are the primary drivers of global warming, which destabilizes climate systems worldwide.

The endangerment finding had provided the legal foundation for federal agencies in the United States to limit emissions of these gases. Federal limits on carbon dioxide, methane, and other greenhouse gases meant the government could regulate how much factories, power plants, and vehicles could emit. By removing this rule, the Trump administration effectively weakened the U.S.’s ability to control pollution from major sources of climate change, under the argument that such regulations were costly for industry.

While the White House framed the move as an economic benefit for car manufacturers and energy companies, the environmental and health consequences are significant — and extend well beyond U.S. borders. Greenhouse gases do not respect national boundaries. What is emitted in one country affects the entire planet. This means rising global temperatures, heatwaves, and unpredictable rainfall in the Southern Hemisphere — from Johannesburg’s urban streets to southern Australia’s farmlands — are all linked to emissions that remain unchecked.

Why This Matters for Public Health

The endangerment finding was not just about abstract science; it recognized that rising greenhouse gas concentrations pose direct threats to human health. Higher levels of carbon dioxide and methane lead to more extreme temperatures, which in turn increase the risks of heatstroke, cardiovascular problems, and respiratory diseases. They also worsen air quality, aggravating conditions like asthma and bronchitis, particularly among children and vulnerable populations.

Without federal regulation, these impacts could accelerate. Analysts estimate that reversing the rule could result in tens of thousands of additional premature deaths in the U.S. alone. For environmental journalists, these numbers are more than statistics — they are warnings about the real-world consequences of policy decisions.

Global Implications: What the Southern Hemisphere Should Watch

While the rollback is a U.S. decision, its consequences ripple across the globe. Human activity in one region contributes to planetary warming, which drives extreme weather events worldwide. In southern Africa, for example, we are seeing increasingly scorching days followed by sudden storms, creating unstable conditions for agriculture, water supply, and urban infrastructure. In Australia, rising temperatures intensify droughts and bushfires.

This is why international environmental policy matters: no country can solve climate change alone. Each increase in greenhouse gas emissions accelerates changes to the planet’s climate system, affecting ecosystems, biodiversity, and human livelihoods everywhere.

The Science Under Threat

The Trump administration’s rationale relies on a report from a hand-picked panel of scientists challenging widely accepted climate science. Yet many experts argue the panel was unrepresentative and biased, failing to accurately reflect decades of peer-reviewed research showing human activity drives global warming.

This highlights a key challenge for environmental journalism: science is often contested in political arenas, and understanding what the evidence actually says is crucial for holding policymakers accountable. By reporting on these issues, we can trace how political decisions intersect with the environment and public well-being.

Beyond Politics: Ecosystem and Environmental Justice Impacts

Environmental rollback policies affect more than human health. Ecosystems, from forests to wetlands, are sensitive to changes in temperature and rainfall. Higher greenhouse gas concentrations increase the likelihood of droughts, wildfires, and floods — threatening biodiversity and disrupting food chains.

Moreover, environmental justice is central. Vulnerable communities — the urban poor, rural farmers, and Indigenous populations — are often the first to feel the effects of climate instability. Policy decisions that prioritize short-term economic gains over emissions control disproportionately impact those already facing resource scarcity and environmental risks.

Conclusion: Why We Should Be Concerned

Trump’s reversal of the endangerment finding is not just an American issue. For environmental journalists and citizens alike, it is a stark reminder that policy choices have immediate and far-reaching environmental consequences. Rising temperatures, erratic rainfall, and ecological disruption in the Southern Hemisphere are part of the same climate system influenced by global emissions.

As we track these changes, it is essential to connect policy decisions to their environmental outcomes, explaining not only what happens but why it matters. Every heatwave, storm, or ecosystem shift is a signal that our collective decisions about greenhouse gases, industry regulation, and environmental protection have consequences — and ignoring them leaves communities and the planet at risk.

Environmental journalism is about illuminating these connections, making science understandable, and holding decision-makers accountable for the health of our shared environment — whether on Earth or, increasingly, as humans expand activity into other planetary environments.
