A Peking University research team led by Wang Heyuan and Wang Kai at the Institute for Carbon Neutrality (ICN) used AI models to determine that the global land carbon sink has drastically shrunk due to an abrupt and extreme jump in global temperature. Their study, "AI-tracked halving of global land carbon sink in 2024," was published in Science Bulletin.

A research team led by Professor Zhang Qinghong and Li Rumeng from the Department of Atmospheric and Oceanic Sciences at Peking University (PKU) School of Physics, has found that hailstorms in China have surged since the Industrial Revolution, likely due to human-driven climate warming. The study, published in Nature Communications in September 2025, combines historical records, meteorological data, and artificial intelligence to track long-term hailstorm trends.

Small mountain ponds high in the tropical Andes may be playing an outsized role in global climate change, according to new research led by scientists at the University of North Carolina.

This study addresses particle acceleration up to relativistic energies via a nonlinear evolution of a large-amplitude Alfvén wave. A multistage process is observed in numerical particle-in-cell simulations. The results provide insights into coherent wave-particle interactions in collisionless plasmas with potential implications for the understanding of high-energy cosmic-ray generation in astrophysical environments such as pulsar magnetospheres, accretion disks, and relativistic jets.
