Warming causes increased sea level from melting of ice sheets and decreased density of water. A King Tide is essentially a Perigean Spring Tide. Even though with warming sea levels will increase, this does not have to do with global warming. Remember not to conflate tides with waves, they are two different (but sometimes related) things. A King Tide is usually defined as two things (weirdly), a Spring Tide at or near Perigee (aka A Perigean Spring Tide), or a Perigean Spring Tide closest to Perhelion (those are the biggest Perigean Spring Tides) Spring Tides are higher high tides and lower low tides that happen on full and dark (new) moons. Perigee is when the moon is closest to the earth. Perhelion (around January 3rd) is when the earth is closest to the sun. So find a full/new moon closest to (or on) Perigee and you'll find Perigean Spring Tides. This is because during the full and new moons the moon, earth and sun are in alignment (Syzygy), this causes the gravitational forces of the moon and sun to be aligned causing higher high tides and lower low tides, basically squeezing the ocean like a zit (not pulling as is usually said). But when the moon is closest to earth (called Perigee) it increases the moons gravitational influence on earth just a bit causing Perigean Spring Tides, so more extreme Spring Tides (higher high tides and lower low tides) (not waves). On quarter moons the gravitational forces of the sun and moon are offset because the moon is at 90° to the sun, this causes Neap Tides, lower high tides and higher low tides. Think of Spring and Neap Tides as a two way, two lane road with solid double lines in the middle. The center double lines are Neap Tides at quarter moons, and the sides of the road are Spring Tides at full and new moons. (Or you can think of it as vagina like)
