Little quantitative research has been devoted to voluntary climate actions at the local level in comparison to those at federal and state levels. It is unclear why some cities act as leaders in the fight against climate change, some act as followers, while others remain laggards. This study empirically tests some hypotheses about local political will to mitigate climate change. Applying a survi...
Given the scarcity of reliable paleoclimate record, surface temperatures first half Earth’s history remain poorly constrained. Here we show how climate-sensitive δ18O value precipitation recorded in Archean igneous and hydrothermal formations can help to resolve state early Earth climate. The Keivy complex, Kola craton (Fennoscandian Shield), formed via intrusion granitic mafic magmas shallow c...
Evolutionary theory suggests that divergent natural selection in heterogeneous environments can result in locally adapted plant genotypes. To understand local adaptation it is important to study the ecological factors responsible for divergent selection. At a continental scale, variation in climate can be important while at a local scale soil properties could also play a role. We designed an ex...
Global climate change is expected to have broad health impacts. These could occur through various exposure pathways, such as the frequency or intensity of extreme heat waves, floods, and droughts. Warmer air temperatures could also influence local and regional air pollutants and aeroallergens. Less direct health impacts may result from climate-related alteration of ecosystems or water and food ...
Climate change poses challenges for decision makers across society, not just in preparing for the climate of the future but even when planning for the climate of the present day. When making climate sensitive decisions, policy makers and adaptation planners would benefit from information on local scales and for user-specific quantiles (e.g. the hottest/coldest 5% of days) and thresholds (e.g. d...
