The main stems
of 38 rivers in the United States are at least 500 miles (800 km) long.
The main stem is "the primary downstream segment of a river, as
contrasted to its tributaries".[1] The United States Geological Survey (USGS) defines a main-stem segment by listing coordinates for its two end points, called the source and the mouth. Well-known rivers like the Atchafalaya,[2] Willamette,[3] and Susquehanna[4] are not included in this list because their main stems are shorter than 500 miles

less far fetched
Explanation:
When plate tectonics was discovered, Wegener's continental drift theory became less far fetched.
Alfred Wegener in 1912 proposed the theory of continental drift. He provided a wide array of evidence to support his claims.
- His idea was not accepted by the scientific community of his days.
- There was no mechanism available and known to account for the moving plates.
- Late on through the years, the idea of mantle convection came into lime light around 1930.
- By 1960, the theory sea floor spreading was already established.
- This lead to the advent of the theory of plate tectonics.
- In the end, the theory of Continental drift became less far fetched and better understood.

Higher temperatures could also lead to steep increases in energy costs in parts of the country, as utilities may need to overbuild their grids to compensate for heavier air-conditioning use in hot months. Labor productivity in many regions is projected to suffer, especially for outdoor workers in sweltering summer heat. And higher sea levels along the coasts would make flooding from future hurricanes far more destructive.
