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/

This means that if methane emission reductions are pursued, the ongoing efforts to reduce emissions of halocarbons and nitrous oxide will become even more important. My thanks to all my co-authors, @UniRdg_Met and the @NERCscience InHALE project.

Our paper looking at the impact of methane emission reductions on stratospheric ozone recovery has been published in GRL https://t.co/a2i9cCbzp3. While methane emission reductions slow surface temperature increases and improve air quality (1/n)

[James Weber @Atmos_Pem]

...we find that they slow stratospheric ozone recovery. This is driven by a reduction in ozone production, and an increase in ozone destruction as gas phase species derived from halocarbons and nitrous oxide become more efficient at destroying ozone. (2/n)

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 https://t.co/OuoBAsGUkE

My thanks to Helen Dacre for her guidance and contribution and the brilliant Openair software from David Carslaw and colleagues.

Checkout our new paper published in ACP this week. We explore how perturbed BVOC emissions driven by land cover changes impact the global atmospheric aerosol burden.

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.

Our paper on the impact of N2O emissions reductions from agricultural soil treatments on stratospheric ozone and climate has been published in npj Climate and Atmospheric Science and is available at https://t.co/5qebvftdKZ 1/n

[James Weber @Atmos_Pem]

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

@SaraMBlich kindly invited me to join her in writing an article for @BulletinAtomic on some of the many ways trees can influence climate. Now freely available at https://t.co/y8lQTkEPWH

[Alexander Archibald @aTarchie]

Pleased to announce a new 2 year PDRA position in our group @ChemCambridge @AtmosScience to investigate the climate impacts of aviation NOx emissions! Advert to job posting will follow soon. DM me if interested and please forward to anyone you think may be interested! @RMetS_Jobs
