NASA shows sea levels falling since 2016

by Robert W. Felix in ClimateChangeDispatch



That’s right, according to NASA, sea levels are going DOWN! This is big news. How come the media hasn’t mentioned it?

NASA satellite sea level observations for the past 24 years show that – on average – sea levels have been rising 3.4 millimeters per year. That’s 0.134 inches, about the thickness of a dime and a nickel stacked together, per year.

Sea Level Rise per Jevrejeva

by Paul Homewood, July 25, 2017


I’ve looked at UK sea level rise, but what about global?

As you can see, the rate of rise was very similar between roughly 1930 to 1960, as it has been since 1990. We see the same pattern at UK sites.

David’s graph mirrors that of the original paper. As with most sources of sea level data, the scale is set to make the rise appear to be astronomic.

Given that the IPCC is forecasting a rise of a meter and more by 2100, a more appropriate scale would look like this …

Tangier Island

by Paul Homewood, July 10, 2017


CBS have a report on rising sea levels at Tangier Island, in Chesapeake Bay here

The video is worth watching. The CBS reporter makes the usual attempts to blame it on “climate change”, but the locals know too much to fall for that old pony.
They know that sea levels have been rising, and land eroding, since 1850.

And they are right. Tide gauges in the area, such Sewell Point, Norfolk, confirm that sea levels have been steadily rising for a long time, long before recent rises in emissions of CO2.

Closely Coupled: Solar Activity and Sea Level

by David Archibald, July 3, 2017


From a post a couple of days ago: “an F10.7 flux above 100 causes warming and below that level causes cooling.” Greg asked “Can you prove that?” I already had in this WUWT post from 2012. But it is worth revisiting the subject because it answers the big question – If all the energy that stops the Earth from looking like Pluto comes from the Sun, what is the solar activity level that corresponds to our average climate? Because solar activity is falling and climate will follow.

A 500-Year Record of Sea Level from Goa, India

by N.-A. Mörner, June 2017, in J. Coastal Research


Fortunately, as revealed in a number of recent studies, proof of such an acceleration of sea level rise remains elusive (see the many reviews we have posted on this topic under the subheading of Sea Level here). The latest work to demonstrate that there is nothing unusual, unnatural or unprecedented about current rates of sea level rise comes from a paper written by sea level expert Nils-Axel Mörner (Mörner, 2017) and published in the Journal of Coastal Research.

Elévation du niveau de la mer : la précision millimétrique des observations satellitaires est-elle crédible ?

by ‘Uskek’ , 16 juin 2017, in Climato-Réalistes


Les mesures satellitaires  prétendent mesurer l’élévation du niveau de la mer avec une précision millimétrique. Or La précision des radars altimétriques s’exprime en centimètres. Comment  dans ces conditions parvient-on à mesurer un taux d’élévation du niveau de la mer de 3,4 mm par an sur la période 1993-2015 ?

Acceleration in European Mean Sea Level? A New Insight Using Improved Tools

by Phil J. Watson, Journal of Coastal research, May 2017


Key findings are that at the 95% confidence level, no consistent or compelling evidence (yet) exists that recent rates of rise are higher or abnormal in the context of the historical records available across Europe, nor is there any evidence that geocentric rates of rise are above the global average. It is likely a further 20 years of data will distinguish whether recent increases are evidence of the onset of climate change–induced acceleration.

Recent Sea-Level Change at Major Cities

by Rich Taylor, March 29, 2017


Where the ground is stable, typical change appears to be a rise of 1- to 2-mm/y. Rates above 3 mm/y seem to have a substantial component of natural and/or anthropogenic subsidence. Rates above 10 mm/y appear to be a primarily a consequence of human activity, which implies they should be manageable to some degree.
