The next CLIVAR climate risk seminar is April 28 at 4 pm ET. We have two fantastic presentations on the schedule. Join the mailing list to get the info to join. mailchi.mp/usclivar.org...

Okay, who knows what happened to relative humidity in 2025?

In a preprint, researchers from Princeton, Hong Kong U, & WRI find that the form of carbon removal called "bioenergy w carbon capture & storage," or BECCS, is "likely to produce higher emissions for decades than using natural gas without carbon capture." This is a Big Deal because the IPCC... 1/3

Today is the deadline to respond to NSF's Dear Colleague Letter about restructuring NCAR -- there is still time to submit comments by emailing [email protected]! www.nsf.gov/funding/info...

NCAR is the backbone of Earth system science in the US and a global leader in open climate research. It directly supports our mission. Alongside a wide range of peers in the scientific research community, we submitted a letter to NSF strongly opposing any efforts to dismantle or restructure NCAR.

I'd love to talk to prospective postdocs who are thinking about the role of land in the climate system about applying! If that's you please reach out!

A team of scientists from @tamu.bsky.social and NCAR (@ncar-ucar.bsky.social) has created an unprecedented set of high-resolution Earth system simulations that is freely available to the scientific community. Learn more about the MESACLIP project: https://bit.ly/4rBK9bg

Our new report, written in collaboration with the Carbon Removal Standards Initiative, presents a framework for policymakers to connect the dots between future net negativity and the practical decisions that underpin public investments in early-stage technologies. carbonplan.org/blog/cdr-pol...

FELLOWSHIP! We’re proud to announce the launch of the Climate Science Serving America fellowship, open to early- and mid-career scientists & engineers who work on climate solutions. Full salary, benefits, and a research stipend. Remote anywhere in the United States. drawdown.org/news/project...

It has warmed my hearth to see we have reached over 200 signatures here :) Thank you to everyone who has put their name down. As this is picking up steam, together with other initiatives, and with some UCAR representatives, we're trying to make sure this reaches the general public, congress & NSF.

I wrote about the first 100% transparent climate risk tool. You can look up your home's wildfire risk, w/ all underlying data, methods, and code available to dl. The hope is to get this info out of black box models and invite public/scientific scrutiny and collaboration. heatmap.news/adaptation/c...

Climate risk modeling is notoriously fraught, but @carbonplan.org is trying anyway — and showing its work. Here's @emilypont.bsky.social with the story: heatmap.news/adaptation/c...

Very excited to see this out in the world, modeling what it looks like to develop fully open-source climate risk tools

I don't say this often but: I'm so proud to be a climate and environment reporter. We cover an issue that is vitally important to humanity and the natural world. 14 of my climate colleagues at the Post were laid off today and I'm devastated. www.climatecoloredgoggles.com/p/washington...

Most carbon removal projects don’t pull CO₂ from the atmosphere instantly — there are temporal lags. We contributed to a new preprint showing why accounting for lags matters for both near-term warming and long-term temperature stabilization. 1/2 carbonplan.org/blog/cdr-tem...

Consistent temporal accounting supports credible CDR use. cdrxiv.org/preprint/302

#SaveNCAR Update: CO Senators aren't backing down on NCAR protections, so now is the time to call your representatives and force the amendment to a vote: wclivestream.com/act/

Philanthropy is vital in advancing the science needed to address global challenges. Our co-founder @wendyschmidt.bsky.social is an inspiring example. Thank you for your unwavering support for science @schmidtocean.bsky.social @schmidtsciences.bsky.social www.forbes.com/sites/elisab...

It's not your imagination: Wildfire smoke in the U.S. has dramatically worsened since 2019. According to a new study, it's already killing 41,000 people a year - and it's poised to get much worse. new from me @johnmuyskens.bsky.social and @sadbumblebee.buzz www.washingtonpost.com/climate-envi...

Our paper "Sensitivity to Data Choice for Index‐Based Flood Insurance" is now published in Earth’s Future! We show that the data chosen to trigger index‑based flood insurance payouts can change everything. agupubs.onlinelibrary.wiley.com/doi/full/10.... #ClimateResilience #FloodInsurance

I'm happy to share a paper in Science Advances that makes the case for a weak land carbon sink, drawing upon JPL and Chloris biomass time series. To close the budget with a net land sink of 0.8 Pg C/y from 2000-2019, we propose increases in the ocean sink and decreases in fossil fuel emissions.

Right then... A quick review of the DOE's new 'critical review' of climate science. Whether it's worth a formal community response - I'm still not sure, but here's my first thoughts /thread/

A synthetic paper about fast vs. slow responses of ecological systems to changing climate, explaining how and why those responses can shift (even in sign) over time. Examples across scales and subdiscplines (population genetics, ecosystem ecology). besjournals.onlinelibrary.wiley.com/doi/10.1111/...

🚨Calling U.S.-based climate experts! The newly formed U.S. Academic Alliance for the @ipcc.bsky.social is now accepting nominations for the Seventh Assessment Report.🌍 Join a global network of scientists shaping the future of climate action. Apply by April 4: buff.ly/hDrBH1F #IPCC #AGU

My hard copies of the BCI book have arrived! 98 chapters of plant and ecosystem science. "All" I need now is a comfy chair, a pot of tea, and no distractions for a week. Downloadable here: smithsonian.figshare.com/articles/boo...

There’s an ongoing debate over what should “count” as CO₂ removal. In a new commentary with @hausfath.bsky.social, we break down key points of contention, proposed definitions, and why no definition offers a perfect path forward. (1/5) carbonplan.org/research/def...

"Others found the financial enticements to leave insulting. 'I don’t work here for the fucking money,' said one longtime agency employee who works on air pollution. 'I work here because I believe in it, and I want to serve the public.'"

GHG emissions from the German LULUCF sector have gone from around neutral to a large source! The change is almost entirely in forest land. "Due to the years of drought, around two million hectares of trees have been damaged and some have died completely." www.thuenen.de/en/thuenen-t... 1/

The extent of Storm #Eowyn’s impact on forests cannot be seen properly from the ground. This drone footage taken today above a stand I visited in Meath shows how wind hardened trees around the edge remain standing while the centre has been flattened.

We maintain a tool that shows how companies use offsets to comply with California’s cap-and-trade program. The tool is now updated with the latest available data, providing a complete picture of offset use in the first decade of the program — from 2013 through 2023. 🧪 carbonplan.org/blog/complia...

One challenge of using National Forest Inventory data for GHG estimates of forest carbon uptake is that only a share of the inventory plots are sampled each year, meaning the last 5 years or so is a guestimate. In Sweden, it looks like forest uptake has stabilised, but... 1/

The meeting is hybrid, so join us online from anywhere for free! Tutorial for running emissions-driven CESM is in person only, and it would be great to see you in Boulder. We will also make all of the materials from the tutorial public.

We have a new preprint out on land-atm interactions in wet regions!

Carbon Dioxide Removal research needs a central, multidisciplinary hub. We’re building it at cdrxiv.org. Read and download others' work, explore CDR pathways and topics, and help the platform grow by submitting your CDR research!

Plant physiological responses to CO2 #fertilization can make natural climate solutions (e.g., reforestation, avoiding #deforestation) less efficient through climate feedback from stomatal closure. @newphyt.bsky.social nph.onlinelibrary.wiley.com/doi/10.1111/...

Really excited for this flat10MIP preprint to come out! In addition to @benmsanderson.bsky.social's points below, I want to add what I think is coolest about these experiments. /Thread/

One year ago, the 5th National Climate Assessment was released! Below is a thread highlighting resources in and around the assessment that you might find useful. nca2023.globalchange.gov

Projects that aim to remove carbon by tweaking existing industrial processes can end up avoiding some emissions as well. That’s a good thing for the climate — but it can pose challenges when trying to support these projects through the sale of carbon removal credits. carbonplan.org/research/cdr... 🧪

We have an opinion piece at the NYT on the need to operationalize some aspects of climate science. 🧪 Thoughts welcome! (Gift link) www.nytimes.com/2024/11/13/o...

The global carbon budget 2024 is out ! Highlights covered in Carbon Brief. @hausfath.bsky.social www.carbonbrief.org/analysis-glo...

The 2024 Global Carbon Budget was just released! Unfortunately despite hopes emissions might peak, both fossil CO2 and total CO2 emissions reached new record highs. I cover details w/ Pierre Friedlingstein (@PFriedling) at Carbon Brief: www.carbonbrief.org/...

We need carbon removal in addition to deep emissions reductions to get to net-zero. But as we show in a new study the durability of removals is key to ensure net-zero actually stabilizes global temperatures and meets our climate goals: www.nature.com/artic...

Land matters for climate! We show how things we don't know about land change surface climate (a lot!) using 36 plausible simulated versions of Earth. Led by Claire Zarakas and just published in Geophys. Res. Lett.: doi.org/10.1029/2024...

I made a list (or 'starter pack') of Land Surface Modelers, because that's the kind of thing one does on #bluesky. Please tell your friends and also (v. important) TELL ME if you want to be added. We need more people here! go.bsky.app/Mw4tJ3t
