The European Union's Copernicus Climate Change Service (C3S) reported data up to November 2025 that show this year has been 1.48 degrees C above the average from 1850 to 1900. That's right around the target set by the 2015 Paris climate agreement, under which countries pledged to limit warming to below 1.5 degrees C and well below 2 degrees C. Despite 2024's record-setting temperatures and 2025's proximity to the 1.5-degrees-C threshold, scientists must take into account many years of data before they can say with certainty that the Paris Agreement's target has been breached.
