Our paper https://t.co/KEi4LyYuYA is new in @ScienceMagazine today. We looked at the impact wide scale forestation (reforestation, afforestation and forest enhancement) would have on atmospheric composition and albedo, comparing these changes to the beneficial removal of CO2. 1/

Extensive forestation changes atmospheric composition and surface reflectivity, offsetting a third of the cooling caused by carbon dioxide removal.

Our new paper on UK air quality finds NO2 and PM2.5 showed robust decreases over 2015-2024 while ozone has increased. All pollutants breach the WHO targets too frequently however. NO2 mainly from traffic, PM2.5 predominantly from sources further afield

The impact of poor air quality (AQ) on public health has long been recognised and considerable efforts have been made to improve it across the UK. The UK has a far reaching AQ monitoring network and...

A belated thank you to @SaraMBlich and Ilona Riipinen for hosting me at @AcesSthlmUni. I enjoyed giving a seminar on BVOCs and climate and discussing how we can improve the modelling of organic aerosols in @UkesmProject. Hopefully the start of a productive collaboration.

The radiative impact of the lower N2O mixing ratios and removal of CO2 via the enhanced rock weathering of the basalt used to treat the agricultural soil (one of two methods considered) equates to a beneficial 9–11 ppm CO2 removal by 2075. 3/n

We find that a 1.35 TgN2O/yr emission reduction applied under SSP3-7.0 (high surface warming) and SSP1-2.6 (low surface warming) future scenarios from 2025 to 2075 leads to a small increase in mid stratospheric ozone but no change to total column ozone or ozone recovery. 2/n

Marine isoprene emissions have implications for atmospheric oxidising capacity and aerosol loading and so knock on implications for climate. Including them in climate models as standard may also change our understanding of the pre-industrial atmosphere and so...

Our paper on combining observations of marine isoprene with modelling in @UkesmProject has been published in @NatureComms. Our study suggests that prior emission estimates of marine isoprene need to be scaled by at least 20x so that models can match observed concentrations. 1/n
