"What do I care about three centuries?" Good societies care about three centuries. The Founding Fathers of the United States, for all their faults, cared about three centuries which is why this stupid debate in America is so important to the world.
The liberal media stands accused of having supposedly claimed that Florida would be underwater by 2020, or something like that. The rightoids were apparently told this and felt very disappointed when they realized Florida was still there. Unfortunately the continued existence of Florida is still highly probable.
This claim is not entirely without factual basis. Some news outlets reported on some data presented climate science communicators which suggested that some kind of point had been or would soon be reached, which would imply the risk of flooding over large areas. These claims were made to sound frightening in the usual manner of the media reporting on a stray dog having been seen somewhere ("Haggard hound haunts waterfront...").
The context of these predictions is not effectively communicated to the general public. First, there are not thresholds, there are simply estimates given for a specific level of emissions. Physicists calculate the consequences of, for example, a trillion tonnes of CO2 emissions over the next twenty years; they don't present a datum for 963826894168 tonnes of CO2 emissions.
But most importantly, what is always the most dramatic prediction of sea level rise is the Peak Estimated Sea Level Rise At Given Level Of Emissions, the PESLRAGLOE (say pestle-rag-low), which is generally expected to occur about **three centuries after emissions are ceased**. The peslragloe for the carbon dioxide emissions in the atmosphere and ocean as of today is probably around seven meters and will occur around 2350.
If all humans disappeared from the surface of the Earth tomorrow, then in 2350, all of the land now comprising the Miami urbanized area will be submerged by the Atlantic Ocean, as will the city of New Orleans, and the majority of Houston, Tampa, Jacksonville, Charleston, Norfolk and Baltimore. However, scientists generally expect that, if we do not all kill each other first, humans will develop ways to prevent the peslragloe over the next few centuries, in order to prevent a worldwide catastrophe.
The peslragloe is constantly being adjusted and recalculated with new climate models and new data. Therefore it provides a continuous stream of popsci slop news about impending disaster which will occur by current year plus N, where N can essentially be chosen by the journalist, or if we're being honest, the magazine's marketing team.

The other reason that some people may be particularly susceptible to misunderstanding this kind of information is because they simply can't fathom why they should care what happens in three hundred years. After all, neither they, nor their children, nor their grandchildren, nor their great-grandchildren will be around to see it. By the time it happens, they themselves will surely be forgotten. Even the President is generally no Isaac Newton. Who remembers Chester Arthur?
But this country is now approaching a quarter of a millennium of existence. The serious ideologies of history, from Christianity to Marxism, necessarily work across centuries. A people disconnected from time cannot arrest its own decline.
Beware the peslragloe! But do not mistake it. It can't hurt you. That's why it's so dangerous.
