2015 Updated NOAA Tide Gauge Data Shows No Coastal Sea Level Rise Acceleration

Watts Up With That?

Guest essay by Larry Hamblin

NOAA has updated its extensive U.S. coastal tide gauge data measurement records (http://tidesandcurrents.noaa.gov/sltrends/sltrends_us.htm) to include data through year 2015. These measurements include tide gauge data coastal locations  for 25 West Coast,  Gulf Coast and East Coast states along the Pacific Ocean, Gulf of Mexico and Atlantic Ocean. In addition 7 Pacific island groups and 6 Atlantic island groups also have coastal location tide gauge data measurements updated as well.

In all more than 200 coastal locations are included in these measurements with more than 100 of these coastal locations with recorded data periods in excess of 50 years in duration. None of these updated NOAA tide gauge measurement data records show coastal location sea level rise acceleration occurring anywhere on the U.S. coasts or Pacific or Atlantic  island groups.

In June of 1988 testimony was provided before Congress by various scientists, including NASA’s…

Introducing the global warming speedometer

Watts Up With That?

A single devastating graph shows official climate predictions were wild

By Christopher Monckton of Brenchley

The new global warming speedometer shows in a single telling graph just how badly the model-based predictions made by the Intergovernmental Panel on Climate Change have over-predicted global warming.

The speedometer for the 15 years 4 months January 2001 to April 2016 shows the [1.1, 4.2] C°/century-equivalent interval of global warming rates (red/orange) that IPCC’s 1990, 1995 and 2001 reports predicted should be occurring by now, compared with real-world, observed warming (green) equivalent to less than 0.5 C°/century over the period.

Observed reality

RSS and UAH monthly near-global satellite lower-troposphere temperature anomaly values for each month from January 2001 to April 2016 were assumed to be broadly accurate and were averaged. The least-squares linear-regression trend on their mean was determined and found equivalent to 0.47 C°/century.

Predictions in IPCC’s Assessment Reports

IPCC (2007, 2013) are…

Is much of our effort to combat global warming actually making things worse?

Climate Etc.

Schmidt’s Histogram Diagram Doesn’t Refute Christy

Gavin Schmidt, wrong again.

Climate Audit

schmidt histogram GLBIn my most recent post,  I discussed yet another incident in the long running dispute about the inconsistency between models and observations in the tropical troposphere – Gavin Schmidt’s twitter mugging of John Christy and Judy Curry.   Included in Schmidt’s twittering was a diagram with a histogram of model runs. In today’s post, I’ll parse Schmidt’s diagram, first discussing the effect of some sleight-of-hand and then showing that Schmidt’s diagram, after removing the sleight-of-hand and when read by someone familiar with statistical distributions, confirms Christy rather than contradicting him.
