Using satellite-derived lower-tropospheric temperature records from 1981–2025, we show that global warming has accelerated significantly since 2015. After removing ENSO and aerosol effects, warming trends reach 0.482 °C decade⁻¹, about four times larger than before 2015. Acceleration rates reach 0.48 °C decade⁻² near 2024, indicating that recent temperature spikes are part of an ongoing acceleration. If sustained, an additional 0.5–1.0 °C of warming could occur within the next decade.
