In a recently carried out article by New York Post (NYP), “the frightening map shows that large coastal cities have quickly dropped into the sea”, reports that a study by NASA claims that several large coastal cities are falling due to a combination of land lowering and rising sea levels with alarm rates. The NYP expressly mentions the problems of sea level in New York City, San Francisco, Los Angeles and other cities, which indicates that its problems are due to a combination of lowering and increasing seas, the latter being tightened by climate change. The latter point is misleading. Lowering land is a well -documented problem in some cities, which largely controls local human activities such as groundwater acquisition, poor urban planning and natural geological processes. Sinking is not due to climate change. Despite the claim of NASA, however, the long -term rise data on the sea level does not support that the seas historically unusual interest rates rise. In fact, the seas have been increasing at a modest and steady speed for over a century, without being associated with significant acceleration with emissions at risk of people.
“In many parts of the world, as on the soiled soil under San Francisco, the country moves faster than the sea itself,” writes Marin Gavorcin, the main author of the NASA study. Who specializes in the remote sensing in the NASA propulsion. “
Alexander Handwerger, another researcher of Jet Propulsion Laboratory from NASA, said the study, said: “The speed is more than sufficient to put people's life and infrastructure in danger.”
“The examination of this descent, the sea level – which has increased due to climate change – could increase more than twice as much in Los Angeles and San Francisco in 25 years,” commented the NYP, but the key to explaining and the study itself is Landabsizesize, non -increasing sea.
Lowering land is a localized problem that is mainly caused by excessive groundwater extraction, infrastructure problems, sediment compression and tectonic shifts. Climate change is not a factor for sinking.
The study published in Science Advances cites short -term data from satellites to imply that the global increase in sea level accelerates an implication that does not question the NYP. However, the real tide measurement data does not support this claim.
Long-term reviews of tide measuring devices taken into account the gold standard for measuring local changes in marine levels.
For example, the Tide measurement data from NOAA from New York Battery Park Station, which has recorded the sea level since 1856, shows a steady increase of around 2.85 millimeters a year – a rate that has been consistent for more than a century. This corresponds closely with the global tide measuring devices, which show that the average sea level has increased with a rate of 1 to 3 millimeters per year since the 1800s. It is important that this gradual increase has not accelerated despite increasing CO₂ emissions in recent decades. See Figure 1 below:
Figure 1: Tide measuring device, which has derived the action of the sea level trend for New York City since 1856. The relative trend of the sea level is 2.94 millimeters/year, with a 95% confidence interval of +/- 0.09 mm/year based on monthly medium sea level data from 1856 to 2024, which corresponds to a change of 0.96 foot in 100 years. Source: Noaa tides and currents.
Similarly, tidal measuring devices in San Francisco show a steady climbing on the sea level, which is even lower than in New York City. (See Figure 2, below)
Figure 2: The relative trend of sea level is 1.98 millimeters/year, with a 95% confidence interval of +/- 0.17 mm/year based on monthly medium -sized sea level data from 1897 to 2024, which corresponds to a change of 0.65 feet in 100 years. Source: NOAA tower and currents
The rate of the increase in the sea level shown in Figure 3 below is lower and still slower.
Figure 3: The relative trend of sea level is 1.05 millimeters/year, with a 95% confidence interval of +/- 0.21 mm/year based on monthly medium -sized sea level data from 1923 to 2024, which corresponds to a change of 0.34 foot in 100 years. Source: Noaa tides and currents.
These three cities mentioned in the NYP article do not show short or long-term acceleration of the sea level increase. In fact, there is hardly any acceleration of the increase in sea levels worldwide, as in the climate in the climate in the climate increases at a look at the sea level. Even if the recent increase in the rise in some satellites are completely due to the artificial climate change, it adds only 0.3 inches per decade to the existing historical trend and is still lower than the rise rate, which has occurred in many periods since the most recent intermediate glaze.
The recent modest trends of sea level contradict the claims that climate change is “scary” and accelerated installments. In fact, several studies have shown that the increase in sea levels since the end of the small ice age in the 19th century, here, here and here, for example, has remained relatively constant. If the greenhouse gas emissions really pushed acceleration, we would expect a sharp upward trend in Tide measuring devices in the past 50 years – but we don't.
A study of 2022 emphasized in climate -oriented show showed that media claims of the increase in sea level are often based on cherry -picked satellite data that do not match the trade fairs based on flooring.
By summarizing the landing of land with the increase in sea level, media, like the NYP, leads the public to mislead that climate change is primarily responsible for the flood threats on coasts. This is scientifically inaccurate and steers from the actual problems with a sink with which cities are faced. By focusing on the causes of land lowering, such as B. Problems with groundwater extraction and the compression of unstable soil and filling to add land to the sea instead of being distracted by the minimal or non -existent role of greenhouse gas emissions, the political decision -makers have the prevention of floods and losses on sea level.
The New York Post has half properly done the story. His reporting would have been better if it would avoid mentioning climate change as a factor for the problems with certain coastal cities.
