The number of days per year with more than 1 inch of precipitation will increase across the Northern Great Plains by the middle of the century.

Submitted by dshannon on

Most of the region is projected to experience 0 to 45% more days each year with more than an inch of precipitation by the middle of the century. An increase in heavy precipitation events is expected for much of the region, other than high mountain areas in the southwestern area. By 2050, the frequency of two-day heavy rainfall events is expected to increase by 50%. The amount of rain falling in heavy, one-day events is expected to increase by 8-10% by mid-century. Days with more than 2 inches, 3 inches, and 4 inches of precipitation are also expected to occur more regularly.

Precipitation in winter and spring is expected to increase 10%–30% by the end of this century. Summer precipitation is expected to vary, ranging from no change under a low emissions scenario to a 10%–20% reduction.

There is uncertainty between different climate scenarios for future precipitation projections in the Great Plains. Generally, there is a south-to-north gradient in annual precipitation projections, with increases projected north of the Nebraska-South Dakota border. However, annual precipitation and streamflow projections show only modest changes. The region already experiences considerable variability in precipitation each year, which contributes to a higher degree of uncertainity about future potential for flooding and drought.

The incidence of wildfire has been on the rise in the Great Plains; changing climate conditions may increase wildfire risks in the region by the end of the century.

Different modeling approaches generally conclude that future climate conditions will increase the risk of wildfire across the Great Plains. Annual fire probability, calculated solely with climate data and physical principles, is projected to increase by 20% to 1200% across the region by the end of the century, with the largest increases occuring in Wyoming and western Montana.

There are projected to be many fewer cool days (days with minimum temperatures less than 28°F), with decreases of 30 days or more per year by mid-century.

The largest decreases in number of cool days are expected in western areas of Montana and Wyoming, with much of this area expecting 35-50 fewer days with a minimum temperature below 28 degrees by the middle of the century. Nebraska and the Dakotas are expected to experience 20-30 fewer cool days.

By the middle of the century, the Northern Great Plains region is expected to experience between 5 and 45 more days per year with a maximum temperature exceeding 90 degrees Fahrenheit.

For an average of seven days per year, maximum temperatures reach about 95 degrees F in the Northern Plains. By mid-century, much of the region is expected to experience 20-40 more hot days (above 90 degrees F) each year. The southern parts of this region, particularly Nebraska and South Dakota, will experience the largest increase in number of days above 90 degrees F, while mountainous portions of Wyoming and Montana will experience the least.

Temperatures in the Northern Great Plains are projected to increase by 3.5 to 9.5 degrees Fahrenheit between the years 2036-2100.

All climate models agree that temperatures are projected to increase over the 21st century across the Northern Great Plains, with almost uniform temperature increases across the entire region. In winter, the greatest warming is expected in the northeastern part of this region, mainly in the Dakotas. Springtime warming is generally smaller than that of other seasons. Summer shows a large amount of warming, with the greatest increases in the southern part of the region, particularly in Nebraska and Wyoming.

Climate Adaptations in the Northeast’s Forest Products Supply Chain: A Vulnerability Assessment for the Primary Forest Products Sector

Changes in the climate, including warmer winters and increased precipitation during some parts of the year, are having a significant influence on the Northeast’s forest products supply chain. A recent report describes specifics of climate impacts and adaptations for three links in the Northeast’s forest products supply chain. Topics include: harvest scheduling, BMPs, roads, and forest health.

Climate Change Vulnerability Assessment for the North-central California Coast and Ocean

EcoAdapt, the Gulf of the Farallones National Marine Sanctuary, and other regional partners conducted a vulnerability assessment to identify how and why focal resources across the North-central California coast and ocean region are likely to be affected by future climate conditions. Climate change vulnerability of 44 focal resources, including eight habitats, populations of 31 species, and five ecosystem services was assessed by considering exposure and sensitivity to climate changes and non-climate stressors and adaptive capacity.
