The State Climate Summaries provided here were initially produced to meet the demand for state-level climate information in the wake of the Third U.S. National Climate Assessment. This 2022 version provides new information and extends the historical climate record to 2020 for each state. The summaries cover assessment topics directly related to NOAA’s mission, specifically historical climate variations and trends, future climate model projections of climate conditions during the 21st century, and past and future conditions of sea level and coastal flooding. Additional background information and links are given below.

Safe and secure water supplies are a continuing fundamental pursuit for life in the West. This 2021 Report provides an assessment of climate change impacts to water uses in the West and adds a new set of West-wide information based in paleohydrology. This report describes our collaborative actions taken to increase the reliability of water and power deliveries since 2016, including: science and research, planning, infrastructure sustainability, efficient hydropower production, and on-the-ground actions to meet needs for irrigation, municipalities, power, Tribes, and the environment.

The 2017 drought was a rapid-onset event for northeast Montana, the Dakotas, and the Canadian Prairies during the spring and summer of 2017. It was the worst drought to impact the U.S. Northern Plains in decades, and it decimated crops across the region, resulting in $2.6 billion in agricultural losses in the U.S. alone. The unique circumstances of this drought created an opportunity to evaluate and improve the efficacy of drought-related coordination, communication, and management within the region in preparation for future droughts.

This drought assessment report spans a Northern Great Plains region that includes North Dakota, South Dakota, and eastern Montana. It begins with an examination of the observed hydroclimatic conditions that led to the 2017 spring and summertime drought and places those conditions into historical context of 1895–present. The role of anthropogenic climate change is assessed through its possible impact on 2017 precipitation, temperature, and soil moisture. Finally, the report examines whether the record-low summertime precipitation that led to the 2017 drought was predicted by modern initialized forecast systems used by drought forecasters.

The Northern Rockies Adaptation Partnership identified climate change issues relevant to resource management in the Northern Rockies region and developed solutions intended to minimize negative effects of climate change and facilitate transition of diverse ecosystems to a warmer climate. Their vulnerability assessment emphasizes water, fisheries, wildlife, forest and rangeland vegetation and disturbance, recreation, cultural heritage, and ecosystem services, which are regarded as key resource areas for local ecosystems and communities. Resource managers used the assessment to develop a detailed list of ways to address climate change vulnerabilities through management actions. The large number of adaptation strategies and tactics, many of which are a component of current management practice, provide a pathway for slowing the rate of deleterious change in resource conditions.

The Montana Climate Assessment (MCA) synthesizes, evaluates, and shares credible and relevant scientific information about climate change in Montana with the citizens of the state. The motivation for the MCA arose from citizens and organizations in Montana who have expressed interest in receiving timely and pertinent information about climate change, including information about historical variability, past trends, and projections of future impacts as they relate to topics of economic concern. This first assessment reports on climate trends and their consequences for three of Montana’s vital sectors: water, forests, and agriculture.
