Biomass Burning in the Tropics: Impact on Atmospheric Chemistry and Biogeochemical Cycles
TL;DR: Widespread burning of biomass serves to clear land for shifting cultivation, to convert forests to agricultural and pastoral lands, and to remove dry vegetation in order to promote agricultural productivity and the growth of higher yield grasses, but it may also disturb biogeochemical cycles, especially that of nitrogen.
Journal ArticleDOI
Atmospheric aerosols: Biogeochemical sources and role in atmospheric chemistry
TL;DR: In this article, two important aerosol species, sulfate and organic particles, have large natural biogenic sources that depend in a highly complex fashion on environmental and ecological parameters and therefore are prone to influence by global change.
Journal ArticleDOI
The Anthropocene: conceptual and historical perspectives
TL;DR: In this article, the Anthropocene epoch has been formally recognized as a new epoch in Earth history, arguing that the advent of the Industrial Revolution around 1800 provides a logical start date for the new epoch.
Journal ArticleDOI
The influence of nitrogen oxides on the atmospheric ozone content
TL;DR: In this paper, the probable importance of NO and NO2 in controlling the ozone concentrations and production rates in the stratosphere is pointed out and some processes which may lead to production of nitric acid are discussed.

TL;DR: Identifying and quantifying planetary boundaries that must not be transgressed could help prevent human activities from causing unacceptable environmental change, argue Johan Rockstrom and colleagues as discussed by the authors, who identify and quantify planetary boundaries.
