debunking sea level rise

The pace of sea level rise remained relatively constant throughout the 20th century, even as global temperatures gradually rose. “Not only is sea level rising, the rise is accelerating – it’s happening faster and faster,” Oppenheimer said. I know that the most recent (2013) report of the Intergovernmental Panel on Climate Change (IPCC) predicts up to about a meter of sea level rise by 2100, which was a large increase over the 2007 report that predicted up to about 0.6 meters. By overlaying social and economic data on a map that depicts sea level rise, a community can see the potential impact that sea level rise can have on vulnerable people and businesses. “Sea level is rising almost everywhere on Earth,” he said, and as he and several others documented in their September 2019 report to the United Nations. For instance, in late 2015, NASA published a study thoroughly debunking bogus United Nations claims about allegedly melting ice in Antarctica allegedly causing sea-level rise. Global sea level rise has accelerated since the 1960s. Higher seas mean more water and more flooding during high tides, hurricanes, and rain storms. As a geologist the measurements don’t add up. your username. Global sea level rise began around the start of the 20th century. In fact, Rockport trumped all 32 stations, exhibiting a rate of sea level rise that the authors say would ultimately leave water levels 0.82 metres higher in 2050 than in 1992. Looking at global data (rather than tide gauge records just from the U.S.) show that sea level rise has been increasing since 1880. Sea level rise isn’t consistent across the globe. Historically, sea levels have been both lower and higher in the past than at present. sea-level increase by 2050 will be about 5 inches (pp. (2016), Jevrejeva et al. Since the end of the last ice age, the average level has risen about 120 meters (400 feet), as depicted in the following figure. The average rate of sea level rise over the period 1993-2018, when satellite measurements have been available, has been around 3.3 mm/year. Sea level rises as a result of melting ice sheets, such as those that cover Greenland and Antarctica. As for future sea level rise, these predictions are based on physics, not statistics. Rise of sea levels is 'the greatest lie ever told' The uncompromising verdict of Dr Mörner is that all this talk about the sea rising is nothing but a colossal scare story, writes Christopher Booker. Log into your account. Global mean sea level in 2018 was higher than any year since measurements started in the late 19th century, about 20 cm higher than at the beginning of the 20th century. The new Sea Level Change Data Pathfinder delves into many of the datasets scientists use to study the status of global and regional sea level change. Evidence for a … If the sea level has been rising like stated this island would be underwater. I have contributed a little to sea level research in the intervening years, and am somewhat familiar with the current predictions. Local measurements of sea level change reflect any vertical motion of the land: if land sinks, sea level rises. Welcome! When scientists refer to changes in sea level, they are referring to changes in the height of the mean sea surface relative to a mean sea level defined by the earth’s geoid. To remove the motion of land from sea level measurements, sea level is measured by instruments on satelltes. In 2014, global sea level was 2.6 inches above the 1993 average—the highest annual average in the satellite record (1993-present). Meanwhile, between 1993 and 2018, the global average was 3.2mm per year. The Social Vulnerability Index , which shows areas of high human vulnerability to hazards, is based on population attributes from Census 2010 (e.g., age and poverty) and the built environment. Past and future sea level rise at specific locations on land may be more or less than the global average due to local factors: ground settling, upstream flood control, erosion, regional ocean currents, and whether the land is still rebounding from the compressive weight of Ice Age glaciers. Global sea level has been rising over the past century, and the rate has increased in recent decades. Sea levels worldwide have risen an average of nearly eight centimetres (three inches) since 1992 because of warming waters and melting ice, a panel of Nasa scientists said on Wednesday. According to LDEO polar experts Marco Tedesco and Robin Bell, since 2000 the consensus that global warming is the cause of sea level has grown stronger and stronger in the scientific community.“The consensus about global warming being responsible for sea level rise comes from the knowledge of the physical processes,” wrote the LDEO scientists in response to emailed questions. A debunking of the "sea level rise is exaggerated" myth, using cartoons from the Cranky Uncle vs. There is clearly no rise in sea level that can be measured accurately with the plus or minus 10cm uncertainty. Sea level rise is increasing. There is something going on to where data is being manipulated to show results that are wanted. Observations show that the global average sea level has risen by about 16 cm (6 inches) since the late 19th century. A catastrophic rise in sea levels is unlikely this century, with ­recent experience falling within the range of natural variability over the past several thousand years, according to a report on peer-­reviewed studies by US climate scientist Judith Curry. Sea Surface Height. There, sea levels had risen much faster than the global average. your password Conversely, if land moves up, sea level appears to be going down. Debunking Climate Myths: “Sea Level Rise Predictions are Exaggerated” Posted on April 13, 2017 May 9, 2017 by awbates In the context of climate change, global sea level is one of the most important factors relative to how much our society will need to adapt in the coming decades. Nationally, sea levels have risen 6.5 inches since 1950. I note particularly that sea-level rise is not affected by the warming; it continues at the same rate, 1.8 millimeters a year, according to a 1990 review by Andrew S. Trupin and John Wahr. Sea level rise can no longer be stopped, so it is urgent that we commence intelligent adaptation as a high priority, argues John Englander. Figure 6. For instance, Lomborg can’t get enough of the IPCC for sea level rise: In its 2007 report, the UN estimates that sea levels will rise about a foot over the rest of the century…. The highest rate of sea level rise was recorded along the Gulf of Mexico shoreline, with Grand Isle, Louisiana, experiencing a 7.93mm annual increase, more than double the global average. Scientists around the world have arrived at the consensus that sea levels have risen by about 1.7 millimeters on average per year since the 1900s, and that the rate of sea level rise is accelerating. Flooding has increased by an average of 233% in the last 20 years. Sea level is rising faster in recent decades; measurements from tide gauges (blue) and satellites (red) indicate that the best estimate for the average sea level rise over the last decade is centred on 3.6 mm per year (0.14 inches per year). 60–61). Between 1900 and 2016, the sea level rose by 16–21 cm (6.3–8.3 in) on average. Global sea level rise has accelerated in recent decades, rather than increase at a steady rate, according to a new study based on 25 years of NASA and European satellite data. More precise data gathered from satellite radar measurements reveal an accelerating rise of 7.5 cm (3.0 in) from 1993 to 2017,: 1554 which is a trend of roughly 30 cm (12 in) per century. Between 1994 and 2014, according to Dr Albert’s research, the Solomons experienced sea level rises averaging 7-10mm per year. “The loud divergence between sea-level reality and climate change theory—the climate models predict an accelerated sea-level rise driven by the anthropogenic CO2 emission—has been also evidenced in other works such as Boretti (2012a, b), Boretti and Watson (2012), Douglas (1992), Douglas and Peltier (2002), Fasullo et al. [The] recent leveling of sea level rise comes on the heels of an unprecedented rate of rise during the four years that preceded it (2011-14). Some coastal areas see triple the average rate of rise while others don’t observe any changes, or can even see a drop in sea level. The recent rate of sea level rise is greater than its average value since 1930. December: Alarmist sea level rise scenarios unlikely, says climate scientist Judith Curry.
