MONDAY 28 AUGUST
Check out the Twitter Moments compilation of the opening and session 1 (past sea-level changes).
a.Tide gauge observations are very valuable but the number of observations decreases back in time and the measurements need to be corrected for vertical land movement
b.Reconstructing global mean sea-level change in the 20th century remains challenging and has implications for estimating the acceleration of SLR
a.The satellite era, and specifically the GRACE era, is the ‘golden age’ of geodetic observations of sea-level change
b.By combining different observational techniques, sea-level changes can be separated into mass and volume contributions
a.Sea-level rise affects coastal erosion at the coast of Rio de Janeiro, resulting in progression or retreat of shorelines depending on the specific location
b.Coastal erosion and wave climate are enhanced more by La Nina than El Nino, opposite to situation in Northern Hemisphere
a.The number of missing and disappeared glaciers can be estimated using a power law relation between the number of glaciers and their volume and hindcasting with a glacier model.
b.Uncharted glaciers do not contribute significantly to a global mean sea-level equivalent at present, but might have contributed significantly to 20th century global mean sea level rise.
a.In low coastal elevation zones, tide gauges underestimate relative sea level change because they are anchored at a depth below shallow subsidence
b.Using a combination of a rod surface elevation table and a marker horizon can be used as an alternative to tide gauges to solve this problem
a.Multi-decadal sea-level variation in the Indian Ocean is mainly due to temperature changes.
b.Internal variability might be the dominant contribution, and sea-level variability is correlated strongly with the Indian summer monsoons.
c.Although monsoons last around 4 months, the effect of the monsoons on sea level lasts for a year.
a.In storm surge models downscaled from global circulation models, the intensity of cyclones near New York city by 2300 increases while storm surge height does not, because the path of the cyclones due to climate change is more seaward (away from New York City).
b.When including sea-level rise in their simulations, different results are obtained, and significant increases in storm surge height are projected.
