Global sea levels are rising faster and faster. It spells catastrophe for coastal towns and cities

For around 2,000 years, global sea levels varied
little. That changed in the 20th century. They started rising and have not
stopped since — and the pace is accelerating. Scientists are scrambling
to understand what this means for the future just as President Trump strips
back agencies tasked with monitoring the oceans.

Since 1993, satellites have kept careful watch over the world’s oceans, allowing scientists a
clear view of how they are behaving. What they have revealed is alarming.
Sea level rise was unexpectedly high last year, according to a recent NASA
analysis of satellite data.

More concerning, however, is the longer-term
trend. The rate of annual sea level rise has more than doubled over the
past 30 years, resulting in the global sea level increasing 4 inches since
1993. Scientists have a good idea how much average sea level will rise by
2050 — around 6 inches globally, and as much as 10 to 12 inches in the
US.

Past 2050, however, things get very fuzzy. The world could easily see
an extra 3 feet of sea level rise by 2100, he told CNN; it could also take
hundreds of years to reach that level. Scientists simply don’t know
enough yet to project what will happen.
