Evaluating Automaker Leaders and Laggards
The Union of Concerned Scientists analysis finds a significant disparity in how automakers deploy electric vehicles (EVs) across the United States. While BMW, General Motors, Nissan, and Tesla are identified as leaders, others like Honda, Toyota, and Fiat Chrysler are labeled laggards due to limited model availability or a lack of plug-in offerings. The report highlights a stark geographic divide, noting that California's Zero Emission Vehicle policy has made it the only state where all available US EV models are offered, while consumers in other regions face severe shortages of EVs at dealerships.

Electrifying the Vehicle Market
The report analyzes the US electric vehicle (EV) market as of 2016, finding that while cumulative sales were nearing 500,000, progress among automakers is uneven. BMW, General Motors, Nissan, and Tesla are identified as leaders, while Honda, Toyota, and Fiat Chrysler are characterized as laggards. A significant disparity in vehicle availability exists between California and the rest of the US, largely attributed to California's Zero Emission Vehicle (ZEV) program. The authors argue that limited model availability and poor dealership inventory outside California hinder the national transition to electric transportation.

Rising Seas Threaten to Inundate Jamestown Island, Virginia
Jamestown Island, the site of the first permanent English colony in North America, faces an existential threat from rising sea levels and severe storm surges. Much of the land is less than five feet above water and is sinking due to groundwater extraction. Local sea levels are rising at more than twice the global average, with projections suggesting a rise of up to six feet by the end of the century. The area is highly vulnerable to stronger North Atlantic storms, as evidenced by Hurricane Isabel in 2003, which caused $20 million in damages to the Colonial National Historical Park and threatened nearly a million artifacts. While the National Park Service has implemented protections like riprap and is monitoring sea level rise, some areas, such as a corner of the original Jamestown Fort, have already been lost.

Moving Cape Hatteras Lighthouse Away from Shifting Shoreline
The Cape Hatteras Lighthouse in North Carolina was moved inland in 1999 to prevent it from being lost to the sea due to coastal erosion and sea level rise. The structure, weighing over 4,800 tons, had seen its distance from the ocean shrink from 1,500 feet at construction to 120 feet by the end of the twentieth century. This relocation serves as an example of the 'hard choices' required to protect historic sites as sea levels in the Outer Banks rise two to three times faster than the global average and Category 4 and 5 hurricanes in the North Atlantic have roughly doubled since 1970.

Fort Monroe, Virginia: Freedom’s Fortress at Risk from Higher Seas and Heavier Rains
Fort Monroe, a national monument in Virginia with significant history regarding the beginning and end of slavery in North America, is highly vulnerable to climate change. Water levels near the fort have risen nearly 1.5 feet since the 1920s, and projections suggest coastal waters could rise up to six feet by the end of the century. The site faces increased frequency and severity of flooding from storm surges and heavy rainfall, as evidenced by significant damage from Hurricane Isabel in 2003. Current protections, such as a seawall built by the Army Corps of Engineers, are based on historic rather than projected rates of sea level rise, leaving the site at risk of further inundation and sewage leaks into Chesapeake Bay.

Front Lines: Rising Seas - Naval Air Station Oceana Dam Neck Annex
The Naval Air Station Oceana Dam Neck Annex faces significant risks from sea level rise, with projections indicating that up to 75% of the installation could be underwater during daily high tides by 2100 under a high-emission scenario. The analysis warns that by the end of the century, a Category 1 storm would expose at least 95% of the station to storm surge flooding, and a Category 4 storm could result in nearly 60% of the installation flooding to depths of 20 feet or more. The document argues that there is a growing gap between current military preparedness and these threats, calling for increased funding for high-resolution modeling, tide gauge networks, and detailed mapping to implement adaptive measures.

Front Lines: Rising Seas: Naval Station Norfolk, Virginia
Naval Station Norfolk is located in a sea level rise hot spot where seas are projected to rise between 4.5 and 6.9 feet by 2100. Projections indicate that by 2050, some areas could flood 280 times per year, and by 2100, up to 60% of the station's land area could be exposed to flooding during extra-high tides. In the highest scenario for 2100, a Category 4 storm could leave 95% of the base under more than 10 feet of water. While the Navy has invested in raising piers and participating in regional studies, the document argues that a large gap remains between current preparedness and future threats, calling for increased funding for high-resolution modeling and detailed mapping.
