Abstract (from Nature Climate Change): In coming decades, warmer winters are likely to ease range constraints on many cold-limited forest insects1,2,3,4,5. Recent unprecedented expansion of the southern pine beetle (SPB, Dendroctonus frontalis) into New Jersey, New York and Connecticut in concert with warming annual temperature minima highlights the risk that this insect pest poses to the pine forests of the northern United States and Canada under continued climate change6. Here we present projections of northward expansion in SPB-suitable climates using a statistical bioclimatic range modelling approach and current-generation general circulation model output under Representative Concentration Pathways 4.5 and 8.5....

Abstract (from Nature Climate Change): Many varieties of short-duration extreme weather pose a threat to global crop production, food security and farmer livelihoods1,2,3,4. Hourly exposure to extreme heat has been identified as detrimental to crop yields1,5; however, the influence of hourly rainfall intensity and extremes on yields remains unknown4,6,7. Here, we show that while maize and soy yields in the United States are severely damaged by the rarest hourly rainfall extremes (≥50 mm hr−1), they benefit from heavy rainfall up to 20 mm hr−1, roughly the heaviest downpour of the year on average. We also find that yields decrease in response to drizzle (0.1–1 mm hr−1), revealing a complex pattern of yield sensitivity...

This project compiled, synthesized, and communicated tailored climate change information to NE CASC stakeholders, including Landscape Conservation Cooperatives (LCC), state and federal agencies, and tribal communities. Our mission is to make climate science actionable by getting to know our stakeholders and the decisions they face, and delivering climate information that is directly relevant to their decisions and priorities. The project team served as a resource to answer individual inquiries related to climate model projections in order to aid climate change adaptation. Additionally, the team contributed to the development of a synthesis document to help the Midwest and Northeast states prepare their threatened...

Historical and projected climate data point toward significant changes in the future for the Northeastern and Midwestern U.S. These changes will include impacts to many species (like birds, fish, and mammals), ecosystems (like forests), and natural resources (like water) that humans appreciate and rely on. In order to prepare for these changes, land and resource managers need to be able to predict how species will respond, what specific mechanisms are driving these changes, and what thresholds wildlife species may soon be pushed across. Crossing these thresholds could lead to rapid change or decline in the health of a wildlife population. In response to this need, a team of researchers is working to identify the...
