Granger causal inference for climate change attribution

May 2025
Mark D Risser, Mohammed Ombadi and Michael F Wehner
Environmental Research: Climate
This peer-reviewed study evaluates the usefulness of different attribution analysis techniques, finding that Granger causation can be particularly helpful in certain circumstances, including rapid attribution analysis.Read More →

Carbon majors and the scientific case for climate liability

April 2025
Christopher W. Callahan, Justin S. Mankin
Nature
This peer-reviewed article outlines a transparent, reproducible and flexible framework to formalize how end-to-end attribution could inform litigation by assessing whose emissions are responsible for which harms.Read More →

Climate warming and elevated CO2 alter peatland soil carbon sources and stability

November 2023
Nicholas O. E. Ofiti, Michael W. I. Schmidt, Samuel Abiven, Paul J. Hanson, Colleen M. Iversen, Rachel M. Wilson, Joel E. Kostka, Guido L. B. Wiesenberg, Avni Malhotra
Nature Communications
This peer-reviewed study examines the impact of warming and elevated atmospheric CO2 on the molecular composition of soil organic carbon. The authors' results indicate that climate change may destabilize carbon storage in peatlands.Read More →

Aerosols overtake greenhouse gases causing a warmer climate and more weather extremes toward carbon neutrality

November 2023
Pinya Wang, Yang Yang, Daokai Xue, Lili Ren, Jianping Tang, L. Ruby Leung, Hong Liao
Nature Communications
This peer-reviewed study assesses the impacts of changing greenhouse gases, aerosols, and tropospheric ozone on a carbon neutral pathway, and finds that as we approach carbon neutrality, atmospheric aerosols become a more important factor.Read More →

Regional but not global temperature variability underestimated by climate models at supradecadal timescales

November 2023
T. Laepple, E. Ziegler, N. Weitzel, R. Hébert, B. Ellerhoff, P. Schoch, B. Martrat, O. Bothe, E. Moreno-Chamarro, M. Chevalier, A. Herbert, K. Rehfeld
Nature Geoscience
This peer-reviewed study reviews the evidence regarding the scale of natural temperature variability during recent millennia, and concludes that existing models may underestimate regional variability in climate outcomes over multi-decadal timescales.Read More →

Understanding and Attribution of Extreme Heat and Drought Events in 2022: Current Situation and Future Challenges

October 2023
Lixia Zhang, Xiaojing Yu, Tianjun Zhou, Wenxia Zhang, Shuai Hu, Robin Clark
Advances in Atmospheric Sciences
This review article examines the role of climate change in notable events of the year in five major regions of the world: China’s Yangtze River region, western Europe, the western U.S., the Horn of Africa and central South America.Read More →

State of the Climate in Africa 2022

September 2023
World Meteorological Organization
World Meteorological Organization
This synthesis report shows that the rate of temperature increase in Africa has accelerated in recent decades, with weather- and climate-related hazards becoming more severe.Read More →

The Largest Ever Recorded Heatwave—Characteristics and Attribution of the Antarctic Heatwave of March 2022

August 2023
Edward Blanchard-Wrigglesworth, Tyler Cox, Zachary I. Espinosa, Aaron Donohoe
Geophysical Research Letters
This peer-reviewed study focuses on the record-breaking Antarctic heatwave in March 2022, assesses the implications of this heatwave for widely-used climate models, and models the impact of anthropogenic climate change on this and future heatwaves. Read More →

July 2023
World Meteorological Organization
World Meteorological Organization
This synthesis report summarizes the state of the climate and the extreme events and their socioeconomic impacts in Asia in 2022.Read More →
