B.11 Temperature Projections from Downscaled Data

B.11.1 Projected Annual Temperature Anomalies

B.11.1 Projected Annual Temperature Anomalies - See detailed description below image

This figure presents six maps of the United States which illustrate projected annual temperature change (degrees Fahrenheit) over the near-term, mid-century and end-of-century time periods for two emissions scenarios. The top three maps represent projected temperature changes based on the A2 emission scenario and the bottom three maps represent projected temperatures changes based on the B1 emission scenario. Both the top and bottom maps to the left are for the near-term time period (2010-3029), the top and bottom middle maps are for the mid-century time period (2040-2069) and the maps furthest to the right are for the end-of-century time period (2070-2099). The A2 scenario maps exhibit higher temperature increases compared with the B1 maps in the mid-century and end-of-century time periods, as evidenced by redder coloring in the A2 maps. The near-term A2 and B1 maps exhibit temperature increases of 1 to 3 degrees Fahrenheit represented by yellow and dark yellow coloring. The A2 near-term map has a small area of light orange in central California, with some dark yellow stretching across the Southwest and Great Plains region, indicating temperature increases of 2.5 to 3.5 degrees Fahrenheit in those areas. In the B1 map, the highest temperature changes of 3.5-4.0 are located in the Texas, Oklahoma and Kansas, as well as western Louisiana and southwestern Arkansas.

The mid-century A2 and B1 maps illustrate projected temperature changes from 3 to 5 degrees Fahrenheit represented by light orange and yellow coloring. The mid-century A2 map is consistently red-orange across the country, indicating temperature increases of around 6 degrees Fahrenheit, with lower increases in Florida, the southeast coast, the southwestern coast of California, and the Pacific Northwest. The mid-century B1 map A2 map is consistently orange, indicating temperature increases of around 3-5 degrees Fahrenheit, with lower increases in Florida, the southeastern coast, northwestern Mexico and the Pacific Northwest. In both the A2 and B1 maps, the end-of-century projections show the most severe temperature increases of approximately 5 to 10 degrees Fahrenheit. The A2 map is colored a bright red across the country, indicating temperature increases of around 9 degrees Fahrenheit. The southern tip of Florida, the western coast of Mexico, the southeastern coast exhibit slightly lower increases. The B1 map ranges from 3.0 degrees Fahrenheit changes in Florida, the southeast coast and the Pacific Northwest to 5.5 to 7.0 degree changes in the Great Plains region, California, Nevada and the Northeast.

B.11.2 Projected Winter Temperature Anomalies

This figure presents six maps of the United States which illustrate projected winter (December, January, and February) temperature change (degrees Fahrenheit) over the near-term, mid-century and end-of-century time periods for two emissions scenarios. The top three maps represent projected temperature changes based on the A2 emission scenario and the bottom three maps represent projected temperatures changes based on the B1 emission scenario. Both the top and bottom maps to the left are for the near-term (2010-3029), the top and bottom middle maps are for the mid-century time period (2040-2069) and the maps furthest to the right are for the end-of-century time period (2070-2099). The A2 scenario maps exhibit higher temperature increases compared with the B1 maps in the mid-century and end-of-century time periods, as evidenced by redder coloring in the A2 maps. The near-term A2 map is largely colored light yellow, indicating a temperature change of 0 to 2 degrees, with a blue area of temperature decrease in south east Montana and western South Dakota. The near-term B1 map is mostly yellow, indicating a temperature change of 1 to 2 degrees, with an area of light orange of higher temperature increase across southern South Dakota, Nebraska, Kansas and Oklahoma.

The mid-century A2 map exhibits temperature increases that range from 2 degrees Fahrenheit in the Pacific Northwest to 3 degrees in Florida and the Southeast. The Southwest and Great Plains regions, particularly Utah, southwestern Colorado, and the southern Great Lakes area have higher temperature increases of 4 to 6 degrees Fahrenheit. The mid-century B1 map exhibits temperature increases of 1 to 2 degrees in the Pacific Northwest, western California, the northern Great Lakes region and the entire southeast, particularly Florida. Higher temperature increases of 4 to 5 degrees are depicted as occurring in the central Great Plains region and the Northeast. The end-of-century A2 map is colored mostly bright red, indicating overall temperature increases of between 7 and 9 degrees Fahrenheit. The Pacific Northwest, the western coast of California and the Southeast have cooler projected increases of around 5 to 6.5 degrees Fahrenheit. The end-of-century B1 map exhibits temperature increases of 3 to 5.5 degrees in the Southwest and Southeast regions, with the Pacific Northwest remaining cooler at 1.5 to 2.5 degree increases. The Great Lakes region and the Northeast region exhibit the highest increases of around 6 to 7 degrees Fahrenheit.

B.11.3 Projected Spring Temperature Anomalies - See detailed description below image

This figure presents six maps of the United States which illustrate projected spring (March, April and May) temperature change (degrees Fahrenheit) over the near-term, mid-century and end-of-century time periods for two emissions scenarios. The top three maps represent projected temperature changes based on the A2 emission scenario and the bottom three maps represent projected temperatures changes based on the B1 emission scenario. Both the top and bottom maps to the left are for the near-term (2010-3029), the top and bottom middle maps are for the mid-century time period (2040-2069) and the maps furthest to the right are for the end-of-century time period (2070-2099). The A2 scenario maps exhibit higher temperature increases compared with the B1 maps in each time period, as evidenced by redder coloring in the A2 maps. The near-term A2 map is largely colored light yellow and yellow, indicating a temperature change of 1 to 2 degrees, with an orange area in the Great Plains region indicating higher temperature increases of around 3 to 4 degrees there. The near-term B1 map is mostly light yellow, indicating a temperature change of 1 to 2 degrees, with an area of darker yellow in Nevada, indicating higher temperature changes of around 2.5 degrees in that area.

The mid-century A2 map exhibits temperature increases that range from 2.5 degrees Fahrenheit in the Pacific Northwest and Florida to 3 degrees in the Southeast. The Great Plains and Southwest exhibit higher temperature increases of around 3.5 to 4.5 degrees Fahrenheit. The mid-century B1 map exhibits temperature increases of 1 to 2 degrees in the Pacific Northwest, northern California, and Florida. The rest of the country tends to exhibit temperature increases of around 3 to 5 degrees. The end-of-century A2 map is colored mostly bright red, indicating overall temperature increases of between 7 and 9 degrees Fahrenheit. The Pacific Northwest, the western coast of California and the Southeast have cooler projected increases of around 5.5 to 6.5 degrees Fahrenheit. The end-of-century B1 map exhibits temperature increases of 4 to 6 degrees throughout most of the country, with higher increases across southern Texas and the Northeast.

B.11.4 Projected Summer Temperature Anomalies

B.11.4 PProjected Summer Temperature Anomalies - See detailed description below image

This figure presents six maps of the United States which illustrate projected summer (June, July and August) temperature change (degrees Fahrenheit) over the near-term, mid-century and end-of-century time periods for two emissions scenarios. The top three maps represent projected temperature changes based on the A2 emission scenario and the bottom three maps represent projected temperatures changes based on the B1 emission scenario. Both the top and bottom maps to the left are for the near-term (2010-3029), the top and bottom middle maps are for the mid-century time period (2040-2069), and the maps furthest to the right are for the end-of-century time period (2070-2099). The A2 scenario maps exhibit higher temperature increases compared with the B1 maps in the mid-century and end-of-century time periods, as evidenced by redder coloring in those A2 maps. The near-term A2 map is colored yellow and dark yellow in the Southeast and Northeast regions, as well as southern California, indicating temperature increases of 1 to 2.5 degrees in those areas, while the interior of the country is light or dark orange, with areas of 4 degree increases apparent in central California, the Pacific Northwest and the central Great Plans region, particularly northeastern Texas, northern Louisiana and Arkansas. The B1 near-term map also has temperature increases of around 2 degrees in the Northeast and Southeast regions, with higher temperature increases of 4.5 to 5.5 degrees centered on northern Texas Oklahoma, and the Pacific Northwest.

The mid-century A2 map exhibits temperature increases of 5 to 8 degrees for most of the country, with particularly high increases in northern California, the Pacific Northwest and the Great Plains. The Northeast and Southeast regions exhibit more moderate increases of around 5 to 6 degrees, and Florida exhibits lower temperature increases of around 3.5 degrees Fahrenheit. The mid-century B1 map exhibits temperature increases of around 3 to 4.5 degrees, except for the Pacific Northwest and the Great Plains regions, which both exhibit higher temperature increases of around 7 to 8.5 degrees. The rest of the country tends to exhibit temperature increases of around 3 to 5 degrees. The end-of-century A2 map is colored mostly bright red with areas of dark purple in the Pacific Northwest and the central Great Plains, indicating overall temperature increases of between 7 and 14 degrees Fahrenheit. Central California and the Pacific Northwest exhibit very high temperature increases of 14 to 15 degrees. The end-of-century B1 map exhibits temperature increases of 6.5 to 7.5 throughout the country, with higher temperature increases expected in the Pacific Northwest and very high increases in central California. The Northeast and Southeast exhibit more moderate temperature increases of around 4.5 to 5.5 degrees Fahrenheit.

B.11.5 Projected Fall Temperature Anomalies

B.11.5 Projected Fall Temperature Anomalies - See detailed description below image

This figure presents six maps of the United States which illustrate projected fall (September, October and November) temperature change (degrees Fahrenheit) over the near-term, mid-century and end-of-century time periods for two emissions scenarios. The top three maps represent projected temperature changes based on the A2 emission scenario and the bottom three maps represent projected temperatures changes based on the B1 emission scenario. Both the top and bottom maps to the left are for the near-term (2010-3029), the top and bottom middle maps are for the mid-century time period (2040-2069), and the maps furthest to the right are for the end-of-century time period (2070-2099). The A2 scenario maps exhibit higher temperature increases compared with the B1 maps in each time period, as evidenced by redder coloring in the A2 maps. The near-term A2 map is colored yellow with a band of light orange and orange from California through the Great Plains to the Northern Great Lakes region. The map indicates that the Southeast, Northeast and Pacific Northwest will exhibit temperature increases of 2 to 3 degrees, with higher increases of around 4 to 5 degrees in the Southwest and northern Great Plains. The B1 near-term map is mostly light yellow, indicating temperature increases of 1.5 to 2.5 degrees Fahrenheit. The Gulf Coast region has slightly higher temperature increases of around 2.5 to 3 degrees.

The mid-century A2 map is largely dark orange, indicating temperature increases of 4.5 to 5.5 degrees Fahrenheit. The northern Great Plains and central California have slightly higher increases, while Florida exhibits lower increases. The mid-century B1 map exhibits temperature increases of around 4 degrees, except for the Southeast region which exhibits more moderate increases of 2 to 3.5 degrees. The end-of-century A2 map is colored mostly bright red with an area of dark red on eastern North Dakota, South Dakota and Nebraska, indicating temperature increases of 7 to 9 degrees. The tip of Florida is colored orange, indicating a more moderate increase of around 5 degrees. Central California and the Pacific Northwest exhibit very high temperature increases of 14 to 15 degrees. The end-of-century B1 map exhibits temperature increases of 5 to 7 degrees throughout the country, with lower temperature increases expected in the Southeast and Northeast. The highest temperature increases of around 8 degrees are centered in the Great Plains region.
