Hi bentway; They don't have to make the move. The weather 4 miles away is indistinguishable from the weather right where they are.

What they need to do is to have new coral start at the appropriate place.

A coral begins life as a planulae. The first thing a planulae does is to swim to the surface. After a few days it settles to the bottom and tries to become a coral.

So the real question is "how far can ocean surface currents move a planulae in a few days". With typical speeds of a 4 miles per hour they can go perhaps a couple hundred miles.

It's natural that coral will adapt to climate change. Over the thousands of years the climate has been changing, up and down, at rates as fast as 100 times as fast as it does now. Animals that cannot adapt do not survive.

P.S. You live in a world where all science news are filtered. Like the emperor with no clothes, the media you rely on will not tell you the truth about global warming. So here's a recent article on adaptation of coral reefs to sea temperature change:

Global Warming Threat to Coral Reefs: Can Some Species Adapt?

Coral reefs are among the ecosystems most severely threatened by global warming, but hopeful new evidence has emerged that some coral species may be able to adapt to warmer oceans. In a study published in the journal PLoS One, an international team of researchers reports that coral populations which unexpectedly survived a massive bleaching event in 2010 in South-East Asian waters had previously experienced severe bleaching during an event in 1998.
