17 de mar. de 2023 · The first of these two satellites, Sentinel-6 Michael Freilich, launched in 2020, with the second slated to head to orbit in 2025. “The 30-year satellite record allows us to see through the shorter-term shifts that happen naturally in the ocean and helps us identify the trends that tell us where sea level is headed,” said JPL’s Ben ...
NOAA's Sea Level Rise map viewer gives users a way to visualize community-level impacts from coastal flooding or sea level rise (up to 10 feet above average high tides). Photo simulations of how future flooding might impact local landmarks are also provided, as well as data related to water depth, connectivity, flood frequency, socio-economic vulnerability, wetland loss and migration, and ...
The NZ SeaRise: Te Tai Pari O Aotearoa programme has released location specific sea-level rise projections out to the year 2300 for every 2 km of the coast of Aotearoa New Zealand. These projections can be accessed through a new online tool developed by Takiwā, a data management and analytics platform. For the first time, New Zealanders will ...
Global sea level has been rising over the past century, and the rate has increased in recent decades.In 2014, global sea level was 2.6 inches above the 1993 average—the highest annual average in the satellite record (1993-present). Sea level continues to rise at a rate of about one-eighth of an inch per year. Higher sea levels mean that deadly and destructive storm surges push farther inland ...
This Sea Level Rise Technical Report provides the most up-to-date sea level rise projections available for all U.S. states and territories; decision makers will look to it for information. This multi-agency effort, representing the first update since 2017, offers projections out to the year 2150 and information to help communities assess potential changes in average tide heights and height ...
Global sea levels have been rising for decades in response to a warming climate. The annual rate of rise – or how quickly sea level rise is happening – has also increased from 0.08 inches/year (0.20 centimeters/year) in 1993 to the current yearly rate of 0.17 inches/year (0.44 centimeters/year). Data on this increase in the rate of global ...
Sea Level Rise. An increase in the average height of the sea surface over a vertical datum. Global mean sea level has risen 101 millimeters (3.98 inches) since 1992, and it currently is rising at approximately 3.9 mm (0.15 inches) per year. Credit: NASA Earth Observatory.
