Sea level rise is accelerating...to the downside
Following a long delay and some controversial "adjustments," the University of Colorado sea level satellite data was recently released. A plot of the rate of sea level rise shows a stable rate between 2003 and 2007, and declining rates since 2007.
Sea levels have been rising since the peak of the last ice age 22,000 years ago and have been decelerating over the past 8,000 years.
See also Inconvenient Truth: Sea Level Rise is Decelerating for evidence that the rate of sea level rise also decelerated in the 20th century:

The last 8 years is too short a period to be used meaningfully to reflect a true long-term trend in sea-level rise. The warmists were using the 1994-2000 period for their claim of rocketing rises; this 2003-2011 period is the reverse part of the cyle. We need a few more years to see what the true, long-term rate is. I vote for a reduced rate from 1970-2000, but I'm a skeptic.
ReplyDeleteDoug,
ReplyDeleteI'm the author of the graph. It uses all the satellite data available, since 1992. The trend for 2003 (~3.5mm/year) is thus the trend from 1992->2003! The same applies for the remaining data, like the value for 2011, which reflects the whole trend 1992->2011. That's why the ***rate*** is going down!

Thanks Ecotretas!
ReplyDeleteBTW I enjoy reading your blog
