‘Since 2003—the last data assessed by the UN IPCC—the rate of sea level rise has slowed’

-

World Climate Report excerpts:

While some alarmists project sea level rise of between 1 to 6 meters (3 to 20 feet) by end of this century, currently sea level is only inching up at a rate of about 20 to 30 centimeters per hundred years (or about 7 to 11 inches of additional rise by year 2100)—a rate some 3-4 times below the low end of the alarmist spectrum, and a whopping 20 to 30 times beneath high end

A couple of months ago, an important paper was published that examined the changing historical contribution of ground water removal (for human water needs, primarily irrigation) to global sea level. A primary finding was that this non-climate component of sea level rise was both significant and rapidly increasing, currently making up between 15 and 25 percent of the current observed rate of sea level rise. Further, the rate of ground water extraction has been increasing over time, which imparts a slight acceleration to the rate of sea level rise over the past half-century or so. Once this non-climate signal is removed, there remains no evidence for a climate-related acceleration. We covered that finding here.

We eat into the 21st century with a rate of sea level rise not much different from that experienced during the 20th century—and one which was hardly catastrophic, readily proven by a simple look around.
