# Caribbean sea sponges indicate faster than expected global warming, study says

New research suggests that the 1.5C global temperature rise limit set by the Paris Agreement may have been breached earlier than anticipated. Chemical changes in Caribbean sea sponges indicate warming linked to human activity as far back as the 1860s. The study suggests that in 2020 warming hit 1.7C, surpassing the Paris Agreement's threshold. While some scientists argue the findings could alter climate change strategies, others caution against extrapolating global trends from regional data. The study underscores the urgency of emissions reductions to mitigate further warming. ([Financial Times)](https://www.ft.com/content/3ddedc2d-bf77-4208-8a0b-3544399fe267)
