Highlights: 

• Sea level has risen 8–9 inches (21–24 centimeters) since 1880.
• In 2019, global sea level was 3.4 inches (87.6 mm) above the 1993 average—the highest annual average in the satellite record (1993-present). This is an increase of 0.24 inches (6.1 mm) from 2018. 
• The rate of sea level rise is accelerating: it has more than doubled from 0.06 inches (1.4 millimeters) per year throughout most of the twentieth century to 0.14 inches (3.6 millimeters) per year from 2006–2015. 
• In many locations along the U.S. coastline, high-tide flooding is now 300% to more than 900% more frequent than it was 50 years ago.
• Even if the world follows a low greenhouse gas pathway, global sea level will likely rise at least 12 inches (0.3 meters) above 2000 levels by 2100.
• If we follow a pathway with high emissions,  a worst-case scenario of as much as 8.2 feet (2.5 meters) above 2000 levels by 2100 cannot be ruled out.

No matter what the U.S. does it will be negated by India and China.  Not much we can do about that.

It's very obvious in Venice where they have been dealing with rising waters for a while now. I heard on some science show that the world should take notes from Venice when it comes to dealing with rising sea levels.

Polar ice caps have melted long before humans existed.  A big volcanic eruption will at some point make a huge change overnight in climate.  Worry about that too.  

You can worry about all this stuff, but you can't change it.  Not unless we go back to no electricity, no nothing.  And then it might not work.

It really isn't something the U.S. has control of no matter what you are told.  Worry more about getting in a car wreck.

"by 2100" - that's 80 years from now. Things will be a lot better by then but not because of low greenhouse gases, etc.

@Cakers3  Much of Florida used to be under water. My DD lives in western MD, near the mountains. She finds rocks in the foothills with marine fossils embedded in them. The world will change with little reguard to what we do. The best we can do is clean up the air we breathe and the water we drink, and improve the way we grow and raise our food.

@PA Mom-mom   Much of Texas was underwater at one time, too.  I went on an excursion digging for marine fossils.  Quite interesting.

I have a box of them and grandson used them for a project in grade school.

@ThinkingOutLoud   You have no idea if things will be a lot better by then.

Anymore than I can say things will be a lot worse by then.

 I stand by what I said. Wish these boards allowed more explanation.
