United States

The United States enters the final stretch of the twenty-first century holding a position no other country can match in raw tourism economics. Travel and tourism contributed roughly $2.36 trillion to American GDP in 2023, supported close to nineteen million jobs, and generated around nine percent of national output once indirect and induced effects are counted. The National Park System recorded an all-time high of 331.9 million recreation visits in 2024, while international arrivals climbed to 72.4 million that same year, recovering to roughly 91 percent of the pre-pandemic peak. By any traditional measure, the country remains the world's most valuable tourism economy by a considerable margin.

Yet 2025 introduced a discordant note. International arrivals fell 5.5 percent to 68.3 million, the first annual decline since 2020, with Canadian visitation dropping nearly 21 percent and German arrivals down more than 11 percent, both responses to political tensions rather than weather. The downturn coincided with a sequence of climate-driven shocks that have begun to rearrange the geography of American tourism. The Lahaina wildfire of August 2023 killed 102 people and destroyed roughly 2,200 structures, suppressing Maui visitor spending by nearly a quarter in the following half-year. Hurricanes Helene and Milton in autumn 2024 together produced around $300 billion in damage. The Palisades and Eaton fires that swept Los Angeles in January 2025 killed 31 people and destroyed approximately 16,000 structures, with loss estimates running from $76 billion to $131 billion. Roughly a third of the tourism asset base that anchored coastal Florida, Hawaii, Southern California, and parts of the Gulf is now meaningfully degraded or operating under chronic insurance stress.

Under the central climate scenario, with emissions tracking between the moderate and high pathways studied by the IPCC, American tourism geography rotates decisively north and inland across the century. Florida's beach corridor, the Outer Banks, the Jersey Shore, Hampton Roads, and the Gulf Coast barrier islands face managed-retreat decisions by midcentury under the intermediate-to-high sea-level trajectories that the Park Service now recommends as planning baselines. The Florida Keys experienced near-total mortality of elkhorn and staghorn corals in 2023, and the fourth global coral bleaching event, declared by NOAA in April 2024, points to structural decline in reef-based tourism through 2050. The Colorado River basin enters 2026 with Lake Mead at roughly 1,056 feet, Lake Powell at about 3,538 feet, combined storage near 36 percent of capacity, and both the 2007 Interim Guidelines and the 2019 Drought Contingency Plan expiring at the end of 2026 with no replacement deal in place. Las Vegas tourism, despite heavy investment in greywater reuse, becomes existentially exposed.

The ski industry contracts toward elevation. Resorts below roughly 2,400 meters lose viability by midcentury, and only the highest properties in Colorado, Utah, Wyoming, and Montana appear dependable into the 2080s. Orlando theme-park operators confront extreme-heat days above 35°C rising from around twenty per year today toward sixty by 2100, pushing Disney, Universal, and SeaWorld toward indoor expansion and shifted peak seasons. Glacier National Park is projected to lose its last named glaciers between 2030 and 2035, transforming the park alongside Glacier Bay and Wrangell–St. Elias into what is in effect a glacier-memorial experience. The countervailing pattern is a meaningful rotation toward climate refugia. The Great Lakes region, the Pacific Northwest interior, Northern New England above the 44th parallel, the Northern Appalachians, the Southern Alaska coast, and parts of the Upper Midwest are positioned to gain tourism share through 2100. Vermont, New York, Michigan, and the Finger Lakes are likely to sustain wine tourism in forms that Napa and Sonoma cannot. The Alaska cruise season extends from May–September toward April–October as Inside Passage ice retreats. Acadia, Voyageurs, Isle Royale, North Cascades, Glacier Bay, and Denali emerge as the parks most likely to absorb visitation that drains from heat-stressed and water-stressed counterparts.

The decisive new variable is artificial-intelligence infrastructure, which behaves less like a separate technology story than like a competing land-and-water user in the very basins that tourism depends on. Project Stargate, announced in January 2025 at a headline figure of $500 billion, anchors its first site in Abilene, Texas, with five additional sites in Texas, New Mexico, Ohio, and Wisconsin announced that September. The International Energy Agency projects United States data-center electricity consumption to rise by roughly 240 terawatt-hours, or 130 percent, between 2024 and 2030, with the agency's executive director stating that data centers are on course to account for almost half of the growth in American electricity demand. Northern Virginia's data-center cluster already absorbs roughly a quarter of that state's total electricity supply, a national-share level comparable to Ireland. A typical 100-megawatt facility consumes around two million liters of water per day through evaporative cooling, placing AI buildout in direct competition with park gateway communities, tribal water rights, and the same Sun Belt and Mountain West basins that tourism shares. The Three Mile Island restart, backed by a Microsoft power-purchase agreement and a federal loan finalized in November 2025, signals that nuclear capacity is being retrofitted for compute rather than civilian load.

Governance volatility has become an independent source of risk. The United States withdrew from UNESCO again in July 2025, effective at the end of 2026, the third such withdrawal in a generation; twenty-six American World Heritage sites remain inscribed, with Everglades National Park retained on the List of World Heritage in Danger by the 2024 Committee. The Denali summit, remeasured by the United States Geological Survey at 6,190 meters in 2015, reverted to the name Mount McKinley by executive order in January 2025. The America the Beautiful interagency pass remains $80 a year for residents but rises to $250 for non-residents starting January 2026, with an additional $100-per-person surcharge planned at the eleven most-visited parks. The National Parks Conservation Association documents a 24 percent loss of permanent Park Service staff in the first half of 2025, layered atop a workforce that had already shrunk by more than a fifth over the previous decade while visitation grew 16 percent. The 2024 record-visitation report was released without the customary public rollout.

Yet there are also points of structural progress. The EXPLORE Act, signed in January 2025, reauthorized the Federal Lands Recreation Enhancement Act through 2031, codified the digital pass, expanded Every Kid Outdoors, and addressed gateway-community housing pressure. The American Indian Alaska Native Tourism Association now anchors a Native hospitality sector worth around $14 billion, with co-management agreements at Bears Ears and Grand Staircase-Escalante setting precedents that tribal nations are likely to extend. Artificial intelligence is no pure adversary either: wildfire-detection systems proved their value during the January 2025 Los Angeles fires, the NOAA Coral Reef Watch satellite-AI system has materially improved bleaching alerts, and machine-learning-driven lottery and timed-entry tools on Recreation.gov are extending Zion- and Arches-style flow management to most flagship parks.

The strategic implication is three horizons. The decade from 2025 through 2055 is the period of climate-shock absorption, when destinations rebuild from megafires, compound hurricanes, coral mortality, and water-allocation failure. The middle window, 2055 through 2080, is the period of managed retreat: coastal home write-downs, sub-2,400-meter ski-resort transitions to four-season recreation, and the slow folding of desert-resort hospitality in places without renewable water. The final two decades, 2080 through 2100, are the period of refugia repositioning, with the Great Lakes, Northern Appalachians, Pacific Northwest, and Southern Alaska carrying disproportionate share of visitation from an American population that the United Nations medium variant projects to reach between 380 and 400 million by century's end. The tourism geography that serves them will not be the one inherited from the twentieth century, and the decisions that shape it are being made now.
