In the early days of the Donald Trump administration, the US Government’s Interior Department cancelled a new policy that would increase the role of science-based evidence in management decision-making for national parks, and take into account the threat of climate change. They decided to Make America Great Again by
cancelling science-based decision-making.
As they are often located in mountains, glaciers, coastal areas, and in regions that are traditionally very hot and dry, US national parks are especially vulnerable to the effects of the climate crisis. Some are warming twice as fast as other parts of the United States.
Recent summers have seen Yosemite National Park hit by savage wildfires, then storms in the following winter that brought so much flooding and snow that park authorities were forced to close Yosemite to visitors for several weeks. Yellowstone National Park meanwhile endured
catastrophic flooding in June 2022 that saw two key access roads destroyed and led to mass evacuations.
The already-extraordinary efforts of park authorities to preserve ecosystems and keep these huge spaces accessible to all will need to be redoubled as the climate crisis takes hold, with lower rainfall, wildfires, flooding, sea level rise and glacier melt among the threats parks will increasingly face. Luckily, after four years of, shall we say, ‘insufficient leadership’ from the Trump administration, the National Park Service’s planning again
takes climate change into account, and has science-based decision-making at its core.
There are two key ways that travellers on a self drive tour can contribute to these efforts. Financially, through your park entrance fees and donations to the park’s maintenance funds, and by going a little crazy in the gift shop. And simply by getting out of the car, helping to cut carbon emissions and air pollution. Many parks offer visitors
free public transport on shuttle buses and trolleys. If you prefer to keep to your own schedule, you can also appreciate parks by hiking, cycling, or kayaking.
