Exploring meteorological forcing decisions in EW models.

Abstract. Land carbon sinks are responsible for removing about a quarter of anthropogenic CO2 emissions, and make up approximately half of total global carbon sinks. Uncertainty in the response of lan...

Enhanced Weathering (EW) is an emerging Carbon Dioxide Removal (CDR) approach within a growing portfolio of mitigation strategies, offering the potential for durable CDR alongside agronomic co-benefit...

Those ousted included ADA journal editor-in-chief Steven Kahn and former ADA president Desmond Schatz

Durably removing ~10 Gt CO₂ yr⁻¹ by 2050 is widely treated as necessary to meet Paris temperature goals. Tracing CDR magnitude claims across ~50 sources spanning five sectors, I found this benchmark d...

Correcting a mis-interpreted equation in EW models.

Marine enhanced rock weathering (mERW) with olivine is a promising carbon dioxide removal (CDR) strategy, but its ecological impacts remain uncertain. In 2022, a first-of-its-kind mERW field trial was...

We were surprised by the high removal rates claimed in a recent credit issuance to the ERW company Lithos. This post explains what questions the issuance raised for us, and what needs to change to get...

We collaborated on a new preprint that establishes clearer language for talking about temporal lags in CDR, and shows how ignoring them can drive near-term warming.

Carbon dioxide removal (CDR) is increasingly used to support national targets and corporate net-zero commitments, yet the timing of atmospheric drawdown remains poorly represented in carbon accounting...

Atmospheric feedbacks reverse the direction of photosynthesis sensitivity to stomatal function in the tropics and high latitudes Stomatal function with higher water cost per carbon gain leads to ...

Katie Wilson has gained a lead that Incumbent Bruce Harrell will be unlikely to beat in the race for Seattle mayor.

Position Summary The Climate and Paleoclimate Lab in the Department of Earth, Environmental, and Planetary Sciences at WashU in St. Louis seeks a Postdoctoral Research Associate in tropical climate/pa...

Ocean Alkalinity Enhancement (OAE) aims to mitigate climate change by increasing the chemical capacity of seawater to store anthropogenic CO2. OAE can be implemented through multiple pathways, each of...

The methods, quantity, and timing of carbon dioxide removal (CDR) is impacted by, and has implications for, decarbonising energy, land use change, agriculture, the earth system response, and global so...

Genome-wide approaches have uncovered the vast microbial and viral diversity across ecosystems. This Review explores advances in metagenomics, single-cell sequencing and functional profiling to elucid...

Both agricultural liming and enhanced weathering spread crushed rocks on fields and have the potential to remove carbon from the atmosphere. We explore how modifying liming for carbon removal works — ...

Enhanced rock weathering with crushed silicates is often considered as an alternative to agricultural liming for soil pH management and carbon dioxide removal. But swapping carbonates for silicates do...

Carbon dioxide removal (CDR) is a crucial component of climate change mitigation strategies, and ocean afforestation via seaweed cultivation has been touted as a promising marine CDR (mCDR) approach d...

We are launching a new platform for openly sharing research results on carbon dioxide removal.

Significant interest and resources are currently being channeled into techniques for durable carbon dioxide removal (CDR) from Earth’s atmosphere. A particular class of these approaches — referred to ...

Enhanced weathering (EW) is a durable carbon removal strategy with clear pathways to produce significant global supply on a decadal scale. Despite increasing interest and investment in this process, t...

Atmospheric carbon dioxide removal (CDR) is required to stabilize global temperature and can be achieved via ecosystem (e.g., soil and forest management) and geological (e.g., direct air capture) carb...

Isometric’s new protocol for wastewater alkalinity enhancement risks counting decarbonization as carbon dioxide removal. The rules could reshape how carbon removal is defined in other pathways, as wel...

Spatial heterogeneity introduces uncertainty when characterizing the Critical Zone, especially when sampling is sparse or requires repeated measurements at the same locations. Here, we layout a probab...

We summarize the ongoing debate around what “counts” as CDR, highlighting the trade-offs of each proposed definition. We suggest an alternative set of questions that can provide a more meaningful guid...

As climate mitigation efforts lag, dependence on anthropogenic CO2 removal increases. Enhanced rock weathering (ERW) is a rapidly growing CO2 removal approach. In terrestrial ERW, crushed rocks are sp...

Carbon dioxide removal (CDR) is a necessary component of limiting global warming to 2°C by 2100. Marine enhanced rock weathering (mERW) with minerals like olivine is a CDR strategy with the potential ...

Rapid deployment of direct air capture and storage (DACS) is essential for meeting net-zero emission targets and requires accurate assessment of both the scale and cost of carbon dioxide removal. This...
