Bin Wang et al. systematically evaluated how #aerosols affect #treegrowth and how these effects are regulated by #cloudcover, #treesize, and #species.

Impacts of aerosols on aspen growth under different sky conditions. (a–c) Beeswarm plots showing the relative influence of predictors on stem relative growth rate (RGR) in the random forest model. Predictors are ordered by importance based on the mean absolute Shapley value. Each point represents the mean Shapley value from 1000 iterations, corresponding to daily tree-level observations under different sky conditions. Points indicate the values of the predictor variable as shown in the color bar. The position along the x-axis reflects the magnitude and direction of each variable’s effect on stem RGR in the model. Overlapping points are jittered to show density. (d–f) Estimated radiative and climatic effects of aerosol on stem RGR. These estimates were derived from a sensitivity analysis of the random forest model, using changes in radiation and climatic variables resulting from a 50 μg m−3 increase in PM2.5 concentration. The bar plot shows the mean effect from 1000 simulation cycles, with error bars representing the standard deviation. Variable abbreviations: TotalR, total radiation; DiffuseF, diffuse radiation fraction; Tair, air temperature; VPD, vapor pressure deficit; SWC, soil water content; DBH, diameter at breast height; RDC, radial daily contraction.

Fig. 1: Scatterplots of layer-mean aerosol optical properties of the automatic versus manual profiles. Shown are the scatterplots for the backscatter coefficients at 355 (a), 532 (b), and 1064 nm (c) wavelength, the Ångström exponents for the 355/532 extinction (d), 355/532 backscatter (e), and 532/1064 nm backscatter wavelength pairs (f), the particle depolarization ratios at 355 (g) and 532 nm wavelength (h), the extinction coefficients at 355 (i) and 532 nm (j), and the lidar ratios at 355 (k) and 532 nm wavelength (l). N denotes the number of layer means. The least-square regression line (dashed magenta), the coefficient of determination (R2), the root-mean-square error (RMSE), the mean absolute error (MAE), the mean bias error (MBE), and the identity line (solid black) are given.

#Atmospheric particles may have significantly slowed surface warming over India.
New research in Ocean-Land-Atmosphere Research shows that #aerosols and #clouds contributed to substantial surface dimming over the region during 2001–2024, offsetting much of the observed #warming trend.👇

The Hidden Climate Risk: Why Global Dimming Demands Urgent Action
@drtomharris.bsky.socialSep 16, 2026, 8:24 AM

The Earth is dimming, allowing more solar radiation to be absorbed, pushing up the energy imbalance and driving the accelerated warming being witnessed around the world. Why is this happening and could there be a solution?

Because we didn't already have enough to worry about, there's this.

Your toilet wants to kill you.
