A three-year Swiss study found that enhanced rock weathering (ERW) removed 10 to 30 times less CO₂ than expected due to soil chemistry and local climate.
Three Years of Field Trials Indicate a Sustained Enhanced Rock Weathering Signal with Limited CO2 Removal
Enhanced rock weathering (ERW) is a CO2 removal technology that involves spreading finely ground silicate rock on fields. The chemical weathering of this rock powder removes atmospheric CO2 in the form of bicarbonate ions and secondary carbonates. Despite some promising theoretical simulations and laboratory findings, results from field trials that evaluate the ERW’s impact on soil biogeochemistry and CO2 removal are still scarce. This study investigated the impact of basaltic rock powder applied at the equivalent rate of 20 t per hectare (2 kg m–2) in three temperate vineyard fields in Switzerland over 1000 days. Analyses of soil pore water revealed that most standard ERW monitoring proxies (pH, electrical conductivity, total dissolved inorganic carbon, calcium, and magnesium concentrations) did not increase significantly. By contrast, sodium concentration in soil pore water was on average 3-fold higher in the rock powder-treated plots, indicating active mineral dissolution. Integrating the pore water results with model analyses, we estimated that the average CO2 removal rate was 100 ± 30 kg CO2 ha–1 yr–1, which is 10 to 30 times lower than the upper rates reported in some previous modeling and experimental studies. Future work is now needed to improve our understanding of ERW’s CO2 removal potential and soil contamination under a variety of soils, rock feedstocks, and climate conditions.

Qianjiadong Reservoir in southern Hunan, China, produces a double harvest: solar energy and yellow carp. The solar farm produces up to 80 megawatts of power while the fish forage beneath the panels. With a massive scale-up of solar and wind at home and cheap exports of the technology, China is driving a worldwide surge of renewable energy—Science’s 2025 Breakthrough of the Year.

The International Monetary Fund asked me to review the literature on migration economics to draw lessons for low-income countries.

In a new @iza.org paper, I argue that policy for the 21st century must discard four outdated ideas.

1. Less skilled labor is abundant. 2. Skilled emigration is a brain drain. 3. Development substitutes for migration. 4. Migration substitutes for failing development, but doesn't cause development.

"The model shows yet another important feature—a hysteresis effect. This means that once social connectivity
surpasses a critical degree and the network is polarized, the polarization is not immediately reversed by lowering
to just below the critical threshold."
doi.org/10.1073/pnas...
Hysteresis of polarization and group formation We demonstrate hysteresis by computing the polarization ψ (as in the main text) for networks with varying initial average degrees (Fig. S4, blue circles). To observe the reversal of polarization, we prepare a network in equilibrium at an average degree of k = 16 (resulting in ⟨k+⟩ ≈ 8.0) and remove links at random until the desired lower connectivity is reached (Fig. S4, downward triangles). Even without explicit influencers, this depolarization process proceeds smoothly, resembling that of systems initialized directly at ⟨k+⟩ with influencers. This hysteresis occurs because politically aligned subgroups emerge in the highly connected, polarized state.

Why more social interactions lead to more polarization in societies

"Increasing social connectivity...can lead to polarization. Inspired by the physics of collective phenomena, we present a simple model that clarifies the underlying mechanisms"
Increase of polarization and social density over time. (A–C) Distribution of ideological opinions in the U.S. electorate. The panels show kernel density estimates of individual ideology, , for Democrats (blue) and Republicans (red) in 1999, 2004, and 2014 based on Pew Research surveys (15). Clearly, ideological divergence is visible over the years. (D) Increase in polarization. Survey-based polarization measure, , over time (gray circles; error bars denote SD in subsampling of selected survey questions; see SI Appendix, section 2). The red line is the model prediction based on parameters , , on a Poissonian small-world with nodes, and a rewiring probability of . The average degree of close friendships, , is taken from the logistic regression in panel (E) (dashed line). The dotted line represents the expected polarization for randomly distributed and noninteracting opinion vectors; see SI Appendix, section 1, for details. (E) Increase in social connectivity. Estimated average number of close friends, , by country (colors) and survey (shapes correspond to GSS, ESS, SCAL, SSND, SCRI, YGov; see SI Appendix, section 3). The dashed line is a logistic regression through all data points. The transition from low to high connectivity appears shortly after Facebook becomes publicly accessible (vertical line I—2006) and overtakes other websites in US traffic (vertical line II—2010) (16).
