Wildfire and degradation accelerate northern peatland carbon release

April 2023
S. Wilkinson, R. Andersen, P. Moore, S. Davidson, and J. Waddington
Nature Climate Change
This peer-reviewed study uses datasets from natural, degraded, and restored northern peatlands to show that increased wildfire incidence caused by human activity reduces the carbon sink provided by peatlands.Read More →

Heat Waves Can Cause Hypoxia in Shallow Lakes

April 2023
Ryuichiro Shinohara, Shin-Ichiro S. Matsuzaki, Mirai Watanabe, Megumi Nakagawa, Hajime Yoshida, Ayato Kohzu
Geophysical Research Letters
This peer-reviewed study examines the factors that might induce hypoxia in a shallow lake during a heat wave, and suggests that the slackening of terrestrial wind speeds in response to climate change will lead to more frequent occurrences of hypoxia.Read More →

A global transition to flash droughts under climate change

April 2023
Xing Yuan, Yumiao Wang, Peng Ji, Peili Wu, Justin Sheffield, Jason A. Otkin
Science Advances
This peer-reviewed study shows that drought intensification rates have sped up over the past 64 years, and that this pattern of "flash droughts" is projected to expand to most land areas, with larger increases under higher-emission scenarios.Read More →

CO2 fertilization effect may balance climate change impacts on oil palm cultivation

April 2023
Tim Beringer, Christoph Müller, Julia Chatterton, Michal Kulak, Sibyll Schaphoff, Yvonne Jans
Environmental Research Letters
This study examines the impact of CO2 fertilization on palm oil yields, and finds that under all climate scenarios yields are anticipated to increase. This contradicts earlier studies, which did not consider positive effects of CO2 fertilization.Read More →

Reduced Tropical Climate Land Area Under Global Warming

March 2023
Ori Adam, Noga Liberty-Levi, Michael Byrne, Thomas Birner
Geophysical Research Letters
This peer-reviewed study examines the extent of tropical climate land areas in the ERA5 and MERRA-2 reanalyses and in high-emission scenarios of 45 climate models. The study finds that climate change will drive a net reduction in tropical land area.Read More →

Warming and Drought Weaken the Carbon Sink Capacity of an Endangered Paleoendemic Temperate Rainforest in South America

March 2023
Jorge F. Perez-Quezada, Jonathan Barichivich, Rocío Urrutia-Jalabert, Enrique Carrasco, David Aguilera, Cédric Bacour, Antonio Lara
JGR: Biogeosciences
This peer-reviewed study finds that warming and drying predicted by climate change models may reduce the capacity of temperate rainforests in southern Chile to act as a carbon sink.Read More →

Synthesis Report of the IPCC Sixth Assessment Report

March 2023
Intergovernmental Panel on Climate Change
Intergovernmental Panel on Climate Change
This Synthesis Report summarizes the state of knowledge of climate change, its widespread impacts and risks, and climate change mitigation and adaptation, based on the peer-reviewed scientific, technical and socio-economic literature since 2014.Read More →

Record-high CO2 emissions from boreal fires in 2021

March 2023
Bo Zheng, Philippe Ciais, Frederic Chevallier, Hui Yang, Josep G. Canadell, Yang Chen, Ivar R. Van Der Velde, Ilse Aben, Emilio Chuvieco, Steven J. Davis, Merritt Deeter, Chaopeng Hong, Yawen Kong, Haiyan Li, Hui Li, Xin Lin, Kebin He, Qiang Zhang
Science
This peer-reviewed study finds that an increase in extreme boreal fires in 2021 resulted in increased CO2 emissions. Increasing numbers of extreme boreal fires and stronger climate–fire feedbacks challenge climate mitigation efforts.Read More →
