TL;DR: In this article, the authors provide an overview and synthesis of some of the most notable types of land cover changes and their impacts on climate, including agriculture, deforestation and afforestation, desertification, and urbanization.

TL;DR: A statistical approach is described to characterize the maximum daily 8-h average O3 (MDA8) for 8 cities in the U.S. for typical, nonfire, conditions and shows that a published method that does not account for transport patterns gives rise to large overestimates in the amount of O3 from fires, particularly for coastal cities.

TL;DR: It is shown that HMS smoke product is a valuable tool for analysis of exceptional events caused by wildland fires and the results indicate that these tools can be valuable for policy and decision makers.

TL;DR: Rainwater samples from over 800 individual precipitation events are used to show that thunderstorms increase Hg concentrations by 50% relative to weak convective or stratiform events of equal precipitation depth, and bridging the scales of global transport and convective precipitation is required.
