no evidence of sea level rise

To find the source of this threat it is necessary to focus on global warming caused by climate change, which causes sea level rise in three different ways: The first is the thermal expansion: water, when heated by temperature rise, tends to expand, ie, oceans take up more space. After 4,000 years ago, the island group continued to be submerged by rising sea levels, even during modest (e.g., 1 mm per year) rates of sea-level rise. 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). The good news is that the Earth does not warm instantly, and mile-thick ice sheets melt even more slowly. "It is … The gathering speed of sea level rise is evident even within the space of a year, with water levels at the 25 sites rising at a faster rate in 2019 than in 2018. The evidence should allay fear that the release of additional CO2 will increase sea-level rise. 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. The early Holocene sea level rise (EHSLR) was a significant jump in sea level by about 60 m during the early Holocene, between about 12,000 and 7,000 years ago, spanning the Eurasian Mesolithic. Flooding as sea level rises could displace millions of people and lead to food shortages. The blue contour (1.8 millimeters per year) shows the average sea level rise if all the water added to the ocean were spread uniformly around Earth. Observations show that the global average sea level has risen by about 16 cm (6 inches) since the late 19th century. The “inevitable” sea-level rise is a result of decades of burning oil, coal and natural gas. Sea level can rise by two different mechanisms with respect to climate change. The second mechanism is the melting of ice over land, which then adds water to the ocean. Figure 6. First, as the oceans warm due to an increasing global temperature, seawater expands—taking up more space in the ocean basin and causing a rise in water level. Those energy sources release gases like carbon dioxide and methane into the atmosphere. But-but-but-but … So the temperature rise will take several decades, and tens of feet of sea level rise will take hundreds and hundreds of years. For example, it's estimated that sea level rise of less than two feet (0.6 meters) will affect 3.8 million people that rely on food from the Nile River delta, and sea level rise of five feet (1.5 meters) will flood out around 17 million people in Bangladesh. Sea level fingerprints (patterns of variation in sea level rise) calculated from GRACE satellite observations of changes in mass due to ice loss and changing water storage on land, 2002-2014.
