It’s well known that global sea levels are rising, but now NASA is showing by just how much.
The National Aeronautics and Space Administration shared an animation that shows how far sea levels have risen between 1993 and 2022.
Over those three decades, sea levels have risen about 3.5 inches.
That may not seem like a lot, but the animation should be used as a visual metaphor. NASA said it’s designed to look like a submerged porthole of a boat as water can be seen lapping outside the window.

3.5 inches doesn’t sound like a lot but many places are only a handful of inches above sea level. I think where I am it’s about 18. So yeah 3.5 is significant.
For homes, shops and industries in port towns, it can make the difference between having a problematic but manageable flood every 20 years, or having hugely damaging floods every 5 years.
Right there at the end it did seem to stir a feeling of anxiety. Maybe it’ll get one denier to start thinking
Problem is, they already think a lot, and can be very smart people. Some of the rationalizations to deny the issue have a lot of logic structure to them. It’s just that they really want - or worse: have personally identified with - an answer.
That’s terrifying in such a short amount of time
The thing is: There are studies that this is because we pulled so much deep ground water above, that it alone equates to 3 inches. Which is a whole different issue, because that apparently also shifted earths magnetic pole. There are ongoing studies about how that may have also shifted earth’s rotational axis, meaning parts of the world that didn’t get so much sun 30 years ago, are now getting a lot more sun. Making the same effects climate change has more pronounced, but they are not because of climate change.

Waving it away with climate change is the wrong conclusion with all of this, because we need to act fast - Europe is loosing ground water extremely fast. Pulling more up due to climate change and also due to more intense sunshine will only worsen the effects, so we need desalination FAST. That Water could also be used for storing clean energy.
