Global average sea level in 2012 was 1.4 inches above the 1993-2010 average, which was the highest yearly average in the satellite record. Sea level has been rising over the past century, and the pace has increased in recent decades.
The total amount of water on Earth isn’t increasing, but the volume of liquid that fills the ocean is growing as ice and snow on land melt. The water is also getting warmer, which makes it expand.
NOAA Coastal and Ocean Climate Applications funding
February 26, 2013
The Coastal and Ocean Climate Applications (COCA) program addresses the needs of specific decision makers grappling with pressing climate-related issues in coastal and marine environments. This program strengthens initiatives to support interdisciplinary applications research aimed at addressing climate-related challenges in coastal communities as well as coastal and marine ecosystems.
Grants are available annually for researchers and decision makers.
Global Sea Level Rise Scenarios for the United States National Climate Assessment
December 6, 2012
Global sea level has been steadily rising for decades and is expected to continue. Scientists have very high confidence that global sea level will rise at least another 8 inches and as much as 6.6 feet by 2100, causing significant impacts in U.S. coastal regions. This report lays out the science and describes possible scenarios to help planners and policy leaders assess the risks.
Technical Considerations for Use of Geospatial Data in Sea Level Change Mapping and Assessment
August 31, 2010
Guidance for federal and state agencies and coastal planners for conducting sea level change assessments and mapping. The report is intended to provide technical guidance to agencies, practitioners, and coastal decision-makers seeking to use and/or collect geospatial data to assist with sea level change assessments and mapping products.
A collection of historical maps and air photos, modern vertical and oblique air photos, and maps depicting rates of shoreline change spaced every 20 meters on the sandy beaches of Maui, Oahu, and Kauai.
