President Donald Trump is renaming the Gulf of Mexico the Gulf of America. But how will that change go into effect – and will everyone call it that?

Mexican President Claudia Sheinbaum has an answer for President Donald Trump about his idea of renaming the Gulf of Mexico to the “Gulf of America:” he can call it whatever he wants on the American part of it.

A geographer explains who decides what goes on the map.

Mexican president says President Trump can call the gulf whatever he wants but that the world will still call it the Gulf of Mexico.

While a name change for the Gulf of Mexico could be applied for federal references, other nations have no obligation to follow suit.

However, Trump's order only applies to the U.S. government's official position. Though headquartered in the U.S., corporations such as Google and Apple aren't beholden to the president's directive to rename the landmarks, raising questions as to whether they'll update their popular map services to reflect the government's stance.

For some crazy reason it’s having a renaissance in all my conversations. I can’t stop trotting it out while on the phone or out in public. "Chilly along the Gulf of Mexico," I’ll chip in as I pass someone in a store.

Among the first executive orders signed by President Donald Trump was an order to rename the Gulf of Mexico to the newly named "Gulf of America." "President Trump is bringing common sense to government and renewing the pillars of American civilization," the newly inaugurated president's executive order said.

The cold air will be somewhat limited, but enough arctic air will wrap around the system that a snowstorm could break out in parts of Arizona, New Mexico and portions of the Plains.

The state of Alaska requested the name change in 1975, but the Board on Geographic Names didn’t take action. Members of the Ohio congressional delegation – President William McKinley was from Ohio – objected over many years to requests to rename the mountain, and the board did not act on those requests.

On his first day in office, Donald Trump launched his second term with a barrage of executive orders. Unsurprisingly, many could have a major impact on Mexico, which shares a 3,145-kilometre border with the US and more than 200 years of diplomatic and economic ties.
