Radiocarbon in roadside plants revealed a decline in auto emissions during COVID lockdown and a 2021 rebound. Could this improve emission estimates in countries without CO2 monitoring infrastructure?
Assigned to another committee? “Ugh,” you say. Think again, and read this article to see how that committee could be an engine of diversity for your organization and for the geosciences.
An innovative integration of models and satellite observations indicates weak temperature sensitivity of CH4 emissions from tropical wetlands, but temperature sensitivity is high at higher latitudes.
The historic disproportionate attrition of women among geoscience faculty is decreasing, but how long will it take to reach gender parity if current trends of progress continue?
Conserving native ecosystems helps sequester carbon and mitigate climate change, but new statistical modeling questions the permanence of California’s carbon-rich forests with climate change.
Progress has been made to reduce methane emission intensity from livestock (the amount of methane per unit of protein), but where are the greatest opportunities to reduce this methane source further?
Modeling the U.S. energy system demonstrates several pathways to net-zero CO2 emissions by 2050. The pathway with the lowest cost, 0.2–1.2% of GDP, relies on >80% contribution of renewables.
The seasonal amplitude of atmospheric CO2 is increasing, partly due to boreal forest responses to warming. Photosynthesis and expansion of boreal forests are shown here to be temperature-limited.
As new AGU leaders assume their governance roles in 2021, about half of the organization’s current officers will continue to serve and provide leadership continuity.
AGU’s Leadership Development/Governance Committee recaps the timing, participation, and other details of the organization’s recently completed 2020 leadership election.
