El Niño to Amplify Heatwaves, Wildfires, Climate Warms
SkimNews Take
While El Niño drives immediate extremes, its impact reveals how underlying climate change has already shifted baseline conditions, making natural variability more severe.

- El Niño is expected to raise the average annual global surface temperature by up to 0.3 °F as it releases stored ocean heat into the atmosphere.
- Fredi Otto of World Weather Attribution warned that a moderate or strong El Niño on top of the current warmer climate creates a “serious risk of unprecedented weather extremes.”
- World Weather Attribution’s assessments show that human‑induced climate change has a far greater influence on the likelihood and intensity of extreme events than El Niño cycles, even eclipsing a strong El Niño’s effect on 2023 rains in the Horn of Africa.
- Jemilah Mahmood warned that heat‑related deaths reach roughly 546,000 per year and that the heat crisis is a public health emergency that is often ignored until it kills silently.
- Theodore Keeping reported that wildfires have already burned an area larger than Alaska—over 500,000 sq mi—50 % more than the 25‑year average, and that El Niño‑driven drought will likely worsen fire conditions across the Amazon, Canada, western United States, Australia, and East Asia.
- Human‑induced climate change remains the main driver of record‑breaking temperature spikes, according to scientists, and will continue to push global temperatures higher regardless of El Niño’s temporary boost.
Why it matters: The convergence of El Niño and ongoing fossil‑fuel warming threatens billions of people with hotter, drier conditions, amplifying heat‑related deaths and expanding wildfire devastation; vulnerable communities, especially those contributing least to emissions, face heightened health costs and loss of livelihoods.
