300 years of sclerosponge thermometry shows global warming has exceeded 1.5 °C
M. T. Mcculloch, A. Winter, et al.
This groundbreaking study reveals that industrial-era warming began in the mid-1860s, earlier than previously believed. Utilizing 300 years of ocean mixed-layer temperature records from sclerosponge carbonate skeletons, the authors uncovered a staggering global warming of 1.7 ± 0.1 °C above pre-industrial levels by 2020, surpassing IPCC projections. Discover the implications of reaching 2 °C by the late 2020s, as conducted by Malcolm T. McCulloch, Amos Winter, Clark E. Sherman, and Julie A. Trotter.
