We found that #arctic #lakes emit less #methane than previously thought. High-resolution mapping shows that in the Arctic (and globally), predictions of total lake area tend to be too high. These findings better match independent measurements of atmospheric methane, which implies a greater fraction of emissions is coming from us! 😨
My latest paper describes this phenomenon in more detail and is published by the #AGU at https://doi.org/10.1029/2023GL104825
Nature: The research led by Google-backed nonprofit Global Fishing Watch revealed that 75% of the world’s industrial fishing vessels are not publicly tracked. Up to 30% of transport and energy vessels also escape public tracking.
"Those blind spots could hamper global conservation efforts, the researchers say. To better protect the world’s oceans and fisheries, policymakers need a more accurate picture”

The massive 2015 flooding of the Sagavanirktok River in northern Alaska had immediate impacts, including closure of the Dalton Highway for several days, but it also contributed to longer-term ground subsidence in the permafrost-rich region. That’s the finding by assistant professor Simon Zwieback at the University of Alaska Fairbanks Geophysical Institute in a study published […]
