Urban trees play an important role in helping cities adapt to climate change, but also are vulnerable changes themselves. We developed approach for assessing vulnerability of urban tree species and cultivars commonly planted the United States Upper Midwest current projected change through end 21st century. One hundred seventy-eight were evaluated their adaptive capacity a suite future-projected stressors using weighted scoring system based on extensive literature review. These scores then adjusted by leading experts arboriculture region.

Upper midwest climate variations: farmer responses to excess water risks.

Persistent above average precipitation and runoff and associated increased sediment transfers from cultivated ecosystems to rivers and oceans are due to changes in climate and human action. The US Upper Midwest has experienced a 37% increase in precipitation (1958-2012), leading to increased crop damage from excess water and off-farm loss of soil and nutrients. Farmer adaptive management respon...

Accepted Article Climate Variability and Vulnerability to Climate Change: a Review Running Head: Climate Variability and Vulnerability Climate Variability and Vulnerability to Climate Change: a Review

The focus of the great majority of climate change impact studies is on changes in mean climate. In terms of climate model output, these changes are more robust than changes in climate variability. By concentrating on changes in climate means, the full impacts of climate change on biological and human systems are probably being seriously underestimated. Here we briefly review the possible impact...
