UNC-Chapel Hill geography unc And if course it wouldn't have been possible if Benjamin Poulter didn't answer a random email from a grad student 10 years ago asking for his data. Let this thread serve as a reminder of how critical data management is for long term investigating of things like climate change.

But these sites are right on North America's second largest estuary, where extreme weather events like storms and drought interact with rising sea level to produce one of the most rapidly changing systems in the world.

This site is a pond pine forest on completely organic soil. The vines and thick shrubs make it hell to work in, but it's so beautiful. Just look at this sphagnum. This is where carbon goes to get sequestered.

Semester is over so I'm back in the field with my grad student Harrison. He's sampling some veg plots that were originally set up by Benjamin Poulter in 2003. That orange rebar is mostly gone, but hanging on in a few plots

Join us for our next NASA ARID update about our dryland scoping study on Wednesday, May 8th at 9-11am MT/11-1pm EST. Meeting details in the link below. Looking forward to seeing you then!

Happy Earth Day, folks!

Today, I’m reminded of the work we must do to protect our planet for future generations.

I’m also reminded of the historic progress we’ve already made — building a cleaner, healthier planet for every American.

And we’re just getting started.

Just in – data from our newest Earth-observing satellite, PACE!

With PACE data, scientists can study microscopic life in the ocean and particles in the air, allowing us to monitor ocean health, air pollution, and impacts of climate change. More: go.nasa.gov/4aNNGe2

🚨New Review

Andrew Feldman, Andrew Felton, Alan Knapp, Benjamin Poulter et al discuss plant responses to fewer but larger rain events

TL;DR: productivity typically increases in dry ecosystems but decreases in wet ecosystems

📢📢 New ways to get involved in the NASA Earth #ARID scoping study posted to the updated website: aridscoping.arizona.edu/get-involved. Continued input from the broader scientific, stakeholder, and govt. agency community is critical as we together assemble the first draft of the report📢📢

The African GHG Budget published, led by yolandi ernst

The African continent is now estimated to be a net carbon source to the atmosphere from both its land systems (e.g., savannas, forests) and human activities (e.g., use of combustion fuels).

Just in: Levels of the three most important human-caused greenhouse gases (GHG)– carbon dioxide, methane & nitrous oxide – continued their steady climb during 2023. Find out how last year’s GHG concentrations measure up to previous years at the link below.

NOAA's annual update of global atmospheric carbon dioxide, methane, nitrous oxide, & SF6 concentrations shows continued imbalance between GHG emissions and removals consistent with previous record growth years research.noaa.gov/2024/04/05/no-…

Global CO2 emissions for 2023 increased by only 0.1% relative to 2022. These 2023 emissions consumed 10–66.7% of the remaining carbon budget to limit warming to 1.5°C, suggesting permissible emissions could be depleted within 0.5–6 years (67% likelihood). nature.com/articles/s4301…

Now fully published, online and open access: agupubs.onlinelibrary.wiley.com/doi/10.1029/20…

We show that the permafrost region might be a net GHG source to the atmosphere when CO2, CH4 and N2O fluxes as well as key ecosystems (land, lake, river) and disturbances are considered. Woodwell Arctic

Interested in land use and climate change? Join us this Friday (3/15) from 11am-noon Eastern for an overview webinar on the Land Cover and Land Use Change Chapter of the Fifth National Climate Assessment ( #NCA5 ). Register here: globalchange.gov/events?topic%5…

Emissions of carbon dioxide rose again in 2023, according to a report co-authored by Goddard’s Dr. Ben Poulter. The greenhouse gas, released by human activities like driving cars and deforestation, is the most significant driver of current global warming.
