The truths and lies of Trump and Musk's X conversation on climate change

In a two-hour conversation on X, former President Trump and Elon Musk debated climate change, offering mixed views on the issue.

Brad Plumer and Raymond Zhong report for The New York Times.


In short:

  • Musk warned that an immediate halt to fossil fuels would be catastrophic, but supported a gradual transition to renewable energy over 50-100 years. He didn't acknowledge even the most aggressive energy transition plans envision a gradual process.
  • Trump expressed skepticism about the viability of electric cars and criticized President Biden’s rollback of drilling in the Arctic National Wildlife Refuge, falsely claiming the protected area has more oil than Saudi Arabia.
  • Both discussed the potential role of nuclear power, with Musk highlighting its safety compared to fossil fuels.
  • They also discussed EV reliance on fossil fuels, cattle ranching relationship to climate change and the effects of carbon dioxide, among other subjects.

Key quote:

“Nuclear electricity generation is underrated...it’s actually one of the safest forms of electricity generation.”

— Elon Musk, CEO of Tesla.

Why this matters:

Musk and Trump influence millions, making their views on climate and energy critical in shaping public opinion and policy. Their contrasting perspectives reflect broader divisions in the American public on how to tackle climate change and manage the transition to sustainable energy. As leaders with vast influence, their views, sometimes based on misinformation, not only drive discourse but also have the potential to steer the direction of national and global climate policies.

Leading cardiology societies call for stronger protections against environmental hazards

Four international cardiology societies — the American Heart Association, the American College of Cardiology, the European Society of Cardiology, and the World Heart Federation — issued a joint statement urging for regulatory action to address the role of toxic environmental exposures in cardiovascular disease.


In short:

  • Growing evidence shows environmental exposures — including air pollution, chemical pollution, plastics, climate change, and artificial noise and light — may be contributing significantly to the rise in cardiovascular disease.
  • Of these hazards, air pollution poses the greatest risk, likely by causing inflammation in the lungs and throughout the circulatory system.
  • The multiple hazards associated with climate change like extreme heat and wildfires may also threaten cardiovascular health via dehydration, arrhythmia, and severe coronary events (such as heart attacks).


Key quote:

"A unified voice was needed to state clearly that the science is settled—and that continued inaction reflects political and structural inertia rather than scientific uncertainty.”

- Lead study author Dr. Thomas Münzel, via JAMA Medical News


Why this matters:

Cardiovascular disease is the leading cause of death worldwide, contributing to roughly 44% of deaths from noncommunicable diseases. When speaking with JAMA Medical News, lead author Dr. Münzel contributed at least 1 in 5 of the 20 million annual global cardiovascular disease deaths to environmental hazards. The authors of this statement call on both policymakers and clinicians to address environmental exposures “with the same seriousness as traditional cardiovascular risks,” fully integrating them into regulations and patient care.
