Later tonight is the launch of #Sentinel6 (3:47 AM my local time). I've been learning so much following the lead up of this amazing multi-agency project, so excited!

A wonderful thing about the world of space is that we are all connected virtually during this time. I've got to take part in some amazing initiatives over the past few months and I look forward to seeing what's coming up!

We know that as human activity warms the planet, global sea level is rising. We know that about 2/3 of sea level rise so far has come from melting ice. But how do we know this? We can measure it from space.

Sea level isn’t uniform around the planet. Tides and currents, the density and temperature of water, and landforms can affect where the ocean piles up. We know this because we measure the shape of the ocean using radar altimetry.

Altimetry works by bouncing radio waves off the ocean surface and timing how quickly they return. Then comes the next challenge: Calculating the natural and seasonal changes in ocean height to determine how much more global warming has made seas rise.
The effects of sea level rise come in many forms. During tropical storms, higher sea levels drive intense storm surges — water level much higher than normal tides. But with sea level rise, the tides themselves can cause flooding.

During high-tide floods, water can make its way from the ocean onto land and bubble up from storm drains. In cities like Miami & Annapolis, high-tide flooding can close down streets & businesses, and damage infrastructure like pipes & wastewater systems.

Between 2000-2015, days with high-tide flooding doubled along the U.S. Northeast Atlantic coast, & that will likely keep climbing. Some locations could see high-tide flooding 180 days a year by 2050. From May '19 to April '20, Annapolis had a record 18 days of high-tide flooding.
Sea levels on the West Coast of the United States are rising at a faster rate than the global average – and that trend is likely to continue for at least a few years, with likely effects for people living in the region.

The height of the sea surface in the western and eastern tropical Pacific Ocean seesaws over time – when one is higher, the other is lower. This is driven on shorter timescales by two natural climate patterns: the El Niño-Southern Oscillation and the Pacific Decadal Oscillation.
Every few years, the El Niño Southern Oscillation (ENSO) pattern produces either an El Niño or a La Niña event. El Niños can increase West Coast sea level; while La Niñas can decrease it.
