Islands of Truth Emerging from the Murky Depths of “Sea Level Science”

Using only the 6 regional tide gauges with 100+ years of data, he found after subtracting subsidence effects from the +1.3 mm/year average relative sea level rise, the average absolute…

Did Manmade Climate Change Cause the Surfside Condo Collapse?

by Anthony R. Lupo In the middle of the night on June 24, 2021, two major sections of Champlain Towers, a 12-story residential condominium in Surfside, FL, just north of…

Sentinel-6 Sea Level Rise—A Follow Up

Since the long record differential GPS corrected (for vertical land motion) tide gauges all show about 2.2mm/year and no acceleration, both data products are useless for any SLR climate purpose.

Run Away: New analysis discusses role of managed retreat as a climate change response

“Managed retreat can be more effective in reducing risk–in ways that are socially equitable and economically efficient–if it is a proactive component of climate-driven transformations,” said Mach, an associate professor…

Claim: An acceleration of coastal overtopping around the world

[editor’s note. It’s really hard to take this press release seriously if they consider the Katrina flooding an indicator of sea level rise. Unmaintained levies break. Absolutely nothing to do…

Sea Level Rise Fastest in 2000 Years (Or Not!)

As the actual data shows, the rate of sea level rise in New Jersey has been pretty constant since 1910, which suggests that carbon dioxide emissions have little overall effect.…

The rocky road to accurate sea-level predictions

“As we said, choosing the wrong equations for the under-ice landscape can have the same effect on the contribution to sea-level rise as a warming of several degrees”, Åkesson says.

Debunked: New Computer Simulated Pine Island Glacier Doomsday Paper By Rosier et al Ignores Lots Of Science

Die kalte Sonne brings up the question: Why were these earlier studies – many based on observations – ignored by Rosier et al? “Hard to believe they were,” says the…

The Supermoon and SLR

“Right now, we’re in the phase of an 18.6-year lunar cycle that lessens the moon’s influence on the oceans. The result can make it seem like the coastal flooding risk…

Current climate model simulations overestimate future sea-level rise

The current climate model simulations, which do not take ocean eddies into account, project that the ocean temperatures around Antarctica are increasing under climate change. The new high-resolution simulation shows…

Changes in ocean chemistry show how sea level affects global carbon cycle

“The new type of information we can read from the stable strontium isotopes now allows us to take a close look at the business end of the global carbon cycle,…

Sea Level and the Jersey Shore

The Jersey Shore does not need to look to the future to see pending disaster – these communities are already at existential risk from the sea levels of today.

Climate adaptation sense. Part III: Dynamic Adaptation Policy Pathways

Best practice is to use 2 to 3 different teams with different perspectives/expertise in generating scenarios and evaluating scenarios of the other teams. I have been involved in three projects…

Climate adaptation follies. Part II: scenarios of future sea level rise

Global sea level rise projections provide a basis for projecting local sea level rise, such as for the New Jersey coast. The analysis in this section places the projections provided…

Climate adaptation follies. Part I: The New Jersey challenge

Mind over Math: Throwing Out the Numbers

See what one might gain by looking at a data set from a new perspective which allows us to throw out the numbers and by doing so, arrive at a…

Historical UK Sea Levels

Kivalina: A Case Study of How Media & Politics Mangle Objective Climate Science!

Kivalina and Newtok don’t exemplify climate crises. Kivalina and Newtok are iconic examples of how the media and governments have ignored the injustices suffered by native peoples, then use their…

New Study: Sea Level Rise Rates The Same Since 1958 As They Were For All Of 1900-2018

A new analysis of global sea level rise rates concludes the rising trend was 1.56 mm/yr−¹ from 1900-2018. This is the same rate as for 1958-2014 (1.5 mm/yr−¹), indicating there…

Huge Database Of Studies Documenting Meters-Higher Mid-Holocene Sea Levels Swells Again In 2020

During the Mid-Holocene sea surface temperatures were also considerably warmer despite CO2 levels only reaching ~265 ppm. Yet at that time sea levels were about 2 or more meters higher…

Alarmism Dies In The Maldives: 97% Of 186 Island Coasts Have Grown (59%) Or Not Changed (38%) Since 2005

Despite sea level rise, a 2019 global analysis (Duvat, 2019) found 89% of 709 island coasts have been either stable or growing in size in recent decades. A new Maldives-only…
