Larry Hamlin's guest essay
NOAA's 2024 measurement of sea level rise data on US stations determined that alarmists have hyped up high-speed accelerated sea level rise rates over 40 years, which is obviously a failure.
In 1988, Democratic politicians claimed that climate models would accelerate future results as artificial carbon dioxide emissions raised by “experts” in their Senate testimony would be presented in their Senate testimony.
At these hearings in 1988, global carbon dioxide emissions were approximately 20.85 billion tons, and since then, by the end of 2023 and by 2023, it has since climbed to approximately 35.13 billion tons.
The entire increase in global CO2 emissions from 1988 to 2023 was caused only by developing countries around the world (24.02 billion metric tons in 2023, 9.27 billion metric tons in 1988), and was dominated by coal fuels, including developed countries, including Emissions in developed countries, including the United States and Europe, were lower than those in 1988 (11.1 billion tons in 2023, compared with 11.59 billion tons in 1988).

During this period, the emission effects of developed countries around the world occurred on their waste of trillions of dollars in extremely unreliable and unmatched renewable energy and the ridiculous zero-zero pipeline, resulting in a huge increase in energy costs, the reliability of energy systems and Reliability of attenuation In these countries, major important enterprises and industries suffered from decline and stagnation, while undermining GDP growth.
At a Democratic Senate hearing in 1988, the so-called “experts” were forward and provided testimony that the increase in global carbon dioxide emissions to date (1988) would lead to accelerated sea level rise over the next decade ( 0.25 inches per year) rises 2.5 inches) as follows, the hearing record is as follows:
“The global average temperature may rise by 0.6 degrees every decade and sea level is 2.5 inches per decade.”
“These are about six times faster than recent history.”
“In addition, as long as greenhouse gases continue to grow in the atmosphere, there is no known natural limitation, namely catastrophic change in warming.”
“Since the ocean’s heat is slow, there is a lag between emissions and the adequate performance of corresponding warming, which is an estimated lag over 40 years.”
“Now, the world is warmer level 1 than it was a century ago, and even if conditions are reduced today, it may be warmer again.”
“Delaying and implementing greenhouse gas elimination policies every decade will ultimately increase the degree in warming and under no circumstances will any policy be fully implemented.”
As mentioned above, global carbon dioxide emissions have risen from 20.85 billion tons in 1988 to 35.13 billion tons, driven by developing countries to 2023.
According to the intervals of climbing carbon dioxide emissions in the 1988 Senate hearing “experts” testimony, this should result in sea level rise accelerations that are much higher than the result of 2.5 inches per decade (0.25 inches per year). Hearing in 1988.
NOAA just released data on relative sea level rise for US radio in 2024. Data for measuring locations during the longest time period in US stations are located in the New York battery (1856-2024), as shown below.

Sea level trend results for 2024 are the same as 2.92 +/- 0.09 mm/year in 2023, although usually the artificial alarm “hottest year” claims.
Shown below is a study of NOAA's battery relative to sea level rise, measuring data from a report released in 2014, released a decade ago, and covering the period from 1856 to 2014.

Note that NOAA's 2014 report points out the following information on these average sea level trend data measurements:
“Although the average trend may change every year, there is no statistically significant difference between the calculated trends if its 95% confidence interval overlaps. Therefore, the latest calculated trends are not necessarily more accurate than previous trends. This is just more Accurate.”
Therefore, since the measured 95% confidence interval for relative sea level uptrend of NOAA battery stations in 2024 is 3.01 to 2.83 mm/yr, there is no statistically significant in the 95% confidence interval for the 2014 year reported year last decade ago Differences in 2014 and 2024 mean relative sea level trend measurements.
There is no statistically significant compared to the average sea level trend in 2007 and the average sea level trend in 2007 or any other average sea level year, including the trend from 1856 to 2006. difference.
Additionally, the difference between average sea level uptrend values for the long-term (2.92 mm/yr – 2.84 mm/yr) from 2014 to 2024 is only +0.08 mm/yr (OR +0.0031 inches/year/year +0.031 inches /+0.0031 inches/ten years) Compared to climate alarms, 0.25 inches/year has been hyped since 1988, and the rate has grown even higher without immediate reduction in emission growth..
According to the 1988 Senate hearing “experts” who accelerated sea level rise by 2.5 inches per ten inches, this is obviously going to happen based on the carbon dioxide emissions that occurred at that time, and a further escalation of sea level rise acceleration. What if emissions are not immediately restricted in the next few decades (never as mentioned above)?
Below is NOAA's 2024 sea level uptrend
Some other U.S. NOAA coastal areas, all of which show the same huge disconnection, while passing average sea level rise trends with claims that accelerated sea level rise from the 1988 Senate hearing, which led to climate alarmers’ energy. and economic damage to widespread global emissions. These hearings initiated a reduction campaign.
Shown below are NOAA data on sea level rise in Honolulu, Hawaii, where President Obama was born, who claimed in his June 3, 2008 Democratic nomination speech that we can review his nomination and tell our children. The moment the ocean rise begins to slow down and our planet begins to heal. ”
NOAA Honolulu relative sea level rise data in 2024 shows that sea level rise in 2023 is 1.56 +/- 0.20 mm/yr, while 1.54 +/- 0.20 mm/yr.

Below are data on NOAA's relative sea level rise relative to sea level at Honolulu Station, starting with their 2014 report, covering a decade ago between 1856 and 2014.
![](https://i0.wp.com/wattsupwiththat.com/wp-content/uploads/2025/02/image-5.jpeg?resize=720%2C330&ssl=1)
NOAA Honolulu Station's relative sea level rise in 2024 resulted in a 95% confidence interval from 1.76 to 1.36 mm/yr, thus overlapping the 95% confidence interval before 2014. Therefore, there was no statistically significant difference between the 2014 value (or any other year shown) ten years ago and the average relative sea level trend measurements for 2024.
Additionally, the difference between average sea level uptrend values for the long term (1.56 – 1.41) from 2014 to 2024 is only +0.15 mm/yr (OR +0.0059 inches/year/year or +0.071 inches/ten inches/ten years ) 1988 speculated 0.25 inches a year, and if emissions growth were not immediately reduced, that value would certainly grow or even higher – of course, this completely failed.
Looking at NOAA's data on the 2024 San Diego station location, we see that the average sea level trend rate in 2024 is 2.23 +/- 0.17 mm/yr, the same as in 2023.

Shown below is NOAA's San Diego Station's relative sea level rise, starting from their 2014 report, covering a decade ago from 1856 to 2014.
![](https://i0.wp.com/wattsupwiththat.com/wp-content/uploads/2025/02/image-1.jpeg?resize=720%2C336&ssl=1)
NOAA San Diego Station's relative sea level rise 95% confidence interval from 2.4 to 2.4 mm/year in 2024, thus overlapping the 95% confidence interval of the previous year of 2014, so there was no statistically significant difference before the first decade of 2014 (or any other year shown) and average relative sea level trend measurements for 2024.
Additionally, the difference between average sea level uptrend values for the long term (2.23 – 2.08) from 2014 to 2024 is only +0.15 mm/yr (OR +0.0059 inches/year/year or +0.071 inches/ten inches/ten years ) 0.25 inches was hyped annually in 1988, and if emissions growth were not immediately reduced, that value would certainly increase.
A broader view of NOAA's updated data for 2024, we're on the U.S. Sea-level Trends (see below) In green, areas with little change in relative sea level are illustrated, including an average global sea level rise with these “green” stations of only 1.7-1.8 mm/yr (approximately 7 inches) mainly present in the United States and Hawaii Coastal areas.
Areas with yellow to red are experiencing global sea level rises, reducing the decline and sinking of local land, resulting in an exaggerated rate of relative sea level rise.
Regions with blue-purple colors are experiencing global sea level rises, with a larger vertical rise, resulting in apparently sea level rises.

NOAA's 2024 updates the relative sea level trend data measurement results, continuing to prove that climate alarms claim that the growth rate of sea level rise acceleration is significantly increasing, while NOAA's overwhelming data reflects the measurement rate of relative sea level rise.
Its time to stop using 40 years of long-failed climate models hype sea level rise plans to empower ridiculous energy policy plans that undermine our necessary and beneficial needs for future economic growth.
