• Boreal–Arctic wetland methane emissions modulated by warming and vegetation activity (2024) · Nature Climate Change · cited 66× · doi

  Abstract Wetland methane (CH 4 ) emissions over the Boreal–Arctic region are vulnerable to climate change and linked to climate feedbacks, yet understanding of their long-term dynamics remains uncertain.

• A multi-model approach to constrain the atmospheric hydrogen budget (2026) · Atmospheric chemistry and physics · doi

  The study uses a simple box model, which may not capture all complexities. The models use present-day atmospheric compositions and fixed hydrogen and methane surface concentrations. The study suggests that more isotopic observations and targeted measurement campaigns are needed.

• Using high frequency observations of δ 13 C-CH 4 and δ 2 H-CH 4 and uncertain regional isotopic signatures to estimate sources of UK methane emissions (2026) · Atmospheric Chemistry and Physics · doi

  There is a need for improved mechanisms for monitoring methane emissions to evaluate current climate change mitigation measures. There is a lack of accurate and reliable methods for estimating regional fossil-fuel and non-fossil-fuel emissions. There is a need for an improved understanding of isotopic signatures and their spatial and temporal variability.

• Using high frequency observations of δ 13 C-CH 4 and δ 2 H-CH 4 and uncertain regional isotopic signatures to estimate sources of UK methane emissions (2026) · Atmospheric Chemistry and Physics · doi

  The method is limited by the accuracy of isotopic source signatures, which can vary spatially and temporally. The method is also limited by the availability of high-frequency observations of δ13C-CH4 and δ2H-CH4. Emissions estimation becomes less accurate when source signature uncertainties are increased to over approximately 50 % of their likely ranges.
