  • Even better, here’s a direct link to a NASA page discussing the data: https://earthobservatory.nasa.gov/images/150192/tracking-30-years-of-sea-level-rise

    Some quotes from the page:

    Scientists have found that global mean sea level—shown in the line plot above and below—has risen 10.1 centimeters (3.98 inches) since 1992. Over the past 140 years, satellites and tide gauges together show that global sea level has risen 21 to 24 centimeters (8 to 9 inches).

    “With 30 years of data, we can finally see what a huge impact we have on the Earth’s climate,” said Josh Willis, an oceanographer at the Jet Propulsion Laboratory and NASA’s project scientist for Sentinel-6 Michael Freilich. “The rise of sea level caused by human interference with the climate now dwarfs the natural cycles. And it is happening faster and faster every decade.”

    The altimetry data also show that the rate of sea level rise is accelerating. Over the course of the 20th century, global mean sea level rose at about 1.5 millimeters per year. By the early 1990s, it was about 2.5 mm per year. Over the past decade, the rate has increased to 3.9 mm (0.15 inches) per year.

    While a few millimeters of sea level rise per year may seem small, scientists estimate that every 2.5 centimeters (1 inch) of sea level rise translates into 2.5 meters (8.5 feet) of beachfront lost along the average coast. It also means that high tides and storm surges can rise even higher, bringing more coastal flooding, even on sunny days. In a report issued in February 2022, U.S. scientists concluded that by 2050 sea level along U.S. coastlines could rise between 25 to 30 centimeters (10 to 12 inches) above today’s levels.












  • I’m not judging you, but to offer another perspective to anyone reading this thread: I am a parent of two young children, and have never not returned a shopping cart. I take the kids with me when I return it.

    As a parent, I realizes that it’s harder to do things with kids than without, but I go out of my way to not pass that burden onto others.

    There are many ways our situations could be different that would make it harder for you to do this than me - your reasons are completely your business.


  • The most intuitive analogy to federation to me is email. You may have an account with one provider (gmail.com in the example of email, or lemmy.world in the example of Lemmy) but you can send emails to other providers (email example) or post messages to other instances (Lemmy).

    Just like with email providers, a Lemmy instance may decide not to allow communication with another instance - this is “defederation.” Instances that allow communication are “federated.”

    Just like email, you don’t normally need to worry much about whether you are on the same instance as a particular community or user - it just works.

    This is a simplification, but for me is a good working model.
