Average High Tide
2000
Tide gauges record sea level every hour, with two high tides each day. "Average High Tide in 2000" is based on high water marks recorded over a 19 year period, from 1983–2001, at the nearest tide gauge.

Projected High Tide
2100
The National Park Service manages parks based on sea level rising 3 feet (0.9m) by 2100. The marker shows high tide in 2100 as 3 feet above average high tide in 2000.*
*Several sources support this. The Intergovernmental Panel on Climate Change (IPCC, 2013) estimates an average global sea level rise of 0.85–2.69 feet (0.21–0.83m) by 2100. Yet, ice sheet melting may be underestimated. The IPCC cites 20 other academic articles with high-end estimates ranging from 1.64–5.12 ft by 2100. The 3-foot marker represents a mid-range projection.

Projected High Tide
2300
The Intergovernmental Panel on Climate Change estimates that average global sea level will rise 0.85 to 12 feet (0.92 to 3.59m) by 2300. The marker shows high tide in 2300 at 12 feet (3.6m) above average high tide in 2000.
Will Sea Level Really Rise This Much?
That depends. Projections vary depending on how much we change our carbon emissions. More than 97% of scientists agree that climate change is mostly caused by human activities, like burning fossil fuels. By reducing our carbon emissions, we can slow the pace of sea level rise.
