TL;DR: In this paper, the authors present the first global assessment of recent tree mortality attributed to drought and heat stress and identify key information gaps and scientific uncertainties that currently hinder our ability to predict tree mortality in response to climate change and emphasizes the need for a globally coordinated observation system.

TL;DR: It is found that one-sixth of the global land surface is highly vulnerable to invasion, including substantial areas in developing economies and biodiversity hotspots, and there is a clear need for proactive invasion strategies in areas with high poverty levels, high biodiversity and low historical levels of invasion.

TL;DR: In this article, the authors examined nine combinations of three sets of potential indicators of the vulnerability of ecosystems to biome change: observed changes of 20thcentury climate, projected 21st-century vegetation changes using the MC1 dynamic global vegetation model under three Intergovernmental Panel on Climate Change (IPCC) emissions scenarios, and overlap of results from (1) and (2).

TL;DR: In this paper, the impacts of climate change on US ecosystems were identified and the authors provided greater mechanistic understanding and geographic specificity for those impacts, including those that affect productivity of ecosystems or their ability to process chemical elements, while combined impacts of wildfire and insect outbreaks decrease forest productivity.

TL;DR: The topics assessed in this chapter were last assessed by the IPCC in 2007, principally in WGII AR4 Chapters 3 (Kundzewicz et al., 2007) and 4 (Fischlin et al, 2007), but also in this paper Sections 1.3.4 and 1.5 (Rosenzweig et al. 2007).
