is the weather severe enough?, page-290

Here you go sailorwhoever, you can thank me anytime you like. Sydney Harbor has risen 3 inches in 100 years and accelerating. Anything more I can help you with?

Sea level is rising at Sydney HarborTide gauges, which continuously measure water height over time relative to land, are a reliable way to determine the extent of long-term sea level rise in an area, according to scientists.This method has been used to measure sea level at Fort Denison, located in Sydney Harbor, since the late 1800s.That long-term tide gauge “has recorded a gradual ... but fairly consistent rise in sea level of 0.1mm/yr or 3 inches/century,” according to Gary Griggs, a professor of earth sciences at UC Santa Cruz. “That rate appears to have increased over the past decade.”This rate – while not insignificant – is lower than the global average, scientists said. That’s because tide gauges measure sea level relative to the land, which is also rising in Australia.The loss of ice from polar continental regions, increasing atmospheric pressure and other water changes around the globe "result in the Australian continent rising slightly," said John Church, a professor emeritus of science at the University of New South Wales who co-authored a study on Australian sea levels.Fact check: Tide gauge data, not photos, prove sea level rise at Statue of LibertyClimate change is accelerating the rate at which the global sea level is rising, according to experts. That acceleration is due to the global warming-induced melting of ice sheets and glaciers, as well as the physical expansion of warming seawater.Photos cannot show the status of sea-level rise because of tidal fluctuationsIt is “virtually impossible” to use photos to determine if there have been any changes to the sea level in Sydney Harbor, or in any location for that matter, according to experts. The two photos in the meme only include information about the year they were taken. No information is provided about the tidal stage or time of day for either picture. “Sydney Harbour has a tidal range of up to 2 meters,” depending on the time of day, Jane Gardner, communications director at the Climate Council told USA TODAY. “The picture would obviously look different depending on the height of the tide when the picture was taken.”USA TODAY has debunked similar claims in the past that attempt to cast doubt on sea-level rise using old photos of prominent landmarks.Our rating: False Based on our research, we rate FALSE the claim that photos prove the sea level hasn't risen in Sydney Harbor. Experts say photos cannot be used to accurately ascertain sea-level change over time. And, sea levels in Sydney Harbor are indeed rising, according to tide gauge data and experts.Our fact-check sources:American Geophysical Union, Aug. 1, 2020, Sea Level Rise Driving Increasingly Predictable Coastal Inundation in Sydney, Australia AP News, July 22, Photos of water at Sydney Harbor fort do not refute sea level riseAustralian Bureau of Meteorology, Accessed Oct. 18, Monthly sea levels for Fort Denison (Sydney) - 1914 to 2022Climate Feedback, Oct. 28, 2019, Photo meme of Sydney Harbour incorrectly claims no sea level rise has occurredCSIRO, accessed Oct. 18, Rising sea levels in Australia may demand novel solutionsGary Griggs, Oct. 19, Email exchange with USA TODAY.
