Extreme Weather and Climate Events

As elevation increases, both temperature and moisture availability decrease. In many parts of the world, this decrease in temperature is a limiting factor for vegetation—at certain elevations, the temperature becomes too cold for plants to survive. However in the tropics, moisture availability may play a more important role than temperature in determining the altitude at which forests...

Surrounded by saltwater, Hawaiian communities depend on freshwater streams for consumption, irrigation, traditional Hawaiian practices, and habitat for native fish and other stream life. It is important to be able to predict how Hawaiʻi’s streams will be affected by changing rainfall patterns to enable sustainable management of critical freshwater resources. However, to date, limited...

The Nome Creek Experimental Watershed (NCEW) has been the site of multiple studies focused on understanding hydrology, biogeochemistry, and ecosystem changes related to permafrost thaw and fire in the boreal forest. The boreal forest is the Earth’s largest terrestrial biome, and thus plays a major role in biogeochemical cycling, creation of habitat for wildlife, as well as wilderness and...

Aspen is an environmentally, economically, and socially important species in the western U.S. It is typically the most abundant deciduous tree species in mountainous landscapes of the western U.S., providing food and habitat for a variety of wildlife, including black bear, deer, elk, moose, and numerous bird species. Aspen woodlands also provide high quality forage for livestock and draw...

Recent extreme floods on the Mississippi and Missouri Rivers have motivated decision-makers and resource managers to expaned floodplain conservation lands. Within Missouri, there are more than 85,000 acres of public conservation lands in large-river floodplains. Floodplain lands are highly dynamic and challenging to manage, particularly climatic conditions change. These lands have the...

Moose and caribou are two very important animals to both subsistence and sport hunting economies in Alaska. Their survival and reproduction is dependent on sufficient winter habitat and food sources, which may be threatened by climate change. During the winter, caribou eat lichens (organisms made up of algae and fungus) that grow on the snow-covered ground. Lichens will likely have a...

Climate change is one of the most pressing issues facing natural resource management. The disruptions it is causing require that we change the way we consider conservation and resource management in order to ensure the future of habitats, species, and human communities. Practitioners often struggle with how to identify and prioritize specific climate adaptation actions (CAAs). Management...

Plants and animals undergo certain life cycle events every year, such as breeding or flowering. Known as phenology, these events are very sensitive to changes in climate. Changes in plant phenology can have cascading effects that impact the herbivore species that depend on the affected plants for food, such as elk, moose, and deer. Therefore, characterizing long term vegetation cycles...

Fire is critical to maintaining and restoring temperate ecosystems in the South Central U.S. As precipitation patterns and temperatures change in the region, managers require information on how these changes will impact fire frequency, and thus the species and ecosystems within the landscape. To address this need, researchers will use climate model data to predict and map future changes...

Prairie ecosystems and the grassland birds that rely on them for habitat may be particularly vulnerable to rapid changes in climate. Extensive portions of prairie have already been lost due to agriculture and urbanization, and as a result grassland birds have declined more than any other bird group in the last four decades. Now, climate change could exacerbate existing threats to these...

Southwestern Colorado is already experiencing the effects of climate change in the form of larger and more severe wildfires, prolonged drought, and earlier snowmelt. Climate scientists expect the region to experience more summer heat waves, longer-lasting and more frequent droughts, and decreased river flow in the future. These changes will ultimately impact local communities and...

Through its Foundational Science Area (FSA) activities, the North Central Climate Science Center (CSC) aims to provide relevant and usable climate information to decision-makers and natural resource managers, so that they can better manage their natural and cultural resources under climate change. Research to meet this objective was implemented in 2013 through three FSAs: (1)...
