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.

TL;DR: In this article, the authors proposed a new approach to global sustainability in which they define planetary boundaries within which they expect that humanity can operate safely. But the proposed concept of "planetary boundaries" lays the groundwork for shifting our approach to governance and management, away from the essentially sectoral analyses of limits to growth aimed at minimizing negative externalities, toward the estimation of the safe space for human development.

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.

TL;DR: The second phase of IGBP as mentioned in this paper describes a strategy for producing high quality, unbiased, credible, fundamental scientific research in the area of global change: a strategy centered on ten projects.

TL;DR: The counterflow virtual impactor probe as mentioned in this paper is an instrument that can sample cloud droplets by removing them from the surrounding air and small unactivated particles through inertial impaction.
