Global warming has slightly slowed the Earth’s rotation — and it could affect how we measure time.

A study published Wednesday found that the melting of polar ice — an accelerating trend driven primarily by human-caused climate change — has caused the Earth to spin less quickly than it would otherwise.

The author of the study, Duncan Agnew, a geophysicist at the Scripps Institution of Oceanography at the University of California San Diego, said that as ice at the poles melts, it changes where the Earth’s mass is concentrated. The change, in turn, affects the planet’s angular velocity.

Agnew compared the dynamic to a figure skater twirling on ice: “If you have a skater who starts spinning, if she lowers her arms or stretches out her legs, she will slow down,” he said. But if a skater’s arms are drawn inward, the skater will twirl faster.

Less solid ice at the poles, then, means more mass around the equator — Earth’s waist.

Having an entire bank staff have ADHD (with the exception of B who is just a narcissist with histronic personality disorder) is hell.

i remember adults telling me, as a kid, to listen to doctors and get my flu vaccine and any shots i could because they remembered Before.

then they started fighting Covid precautions.

i remember adults telling me, as a kid, that the ozone was disappearing and the earth was dying and we needed to recycle and save the planet.

now my parents think climate change is a myth.

i remember adults telling me, as a kid, that racism was a plague, that we had to love and accept everyone, that we should never judge before walking a mile in their shoes.

then they told me that protesting for my Black siblings was wrong.

i remember adults telling me, as a kid, that we needed to give to the poor. working at soup kitchens. making quilts. collecting food and money and supplies. building houses. because it was the christian and just plain right thing to do.

now they look at me, on food stamps with their grandchildren, and lament the "welfare state".

i remember adults telling me, as a kid, that it was easier for a camel to pass through the eye of a needle than a rich man to enter the Kingdom of Heaven and that any rich man, especially an immoral one, should never run our country.

you can guess who they voted for.

i remember adults telling me, as a kid, so very much.

when did they forget?

Have you ever had one of those days where you interact with people and then think to yourself that was not my best work socially?

Hey, happy Earth Day! Who wants to talk about climate change?

Yeah, okay, fair, I kinda figured the answer to that would be "ugh do we have to?" What if I told you I have good news though? Good news with caveats, but still good news.

What if I told you that since the Paris Agreement in 2015, we've avoided a whole degree celsius of global warming by 2100, or maybe more?

Current projections are 2.7C, which is way better than the 3-5C (with a median of 3.7C) we were expecting in 2015. It's not where we want to be - 1.5C - but it is big, noticeable progress!

And it's not like we either hit 1.5C and avoid all the big scary consequences or fail to hit 1.5C and get all of them - every tenth of a degree of warming we avoid is going to prevent more severe problems like extreme weather, sea level rise, etc.

This means that climate change mitigation efforts are having a noticeable impact! This means a dramatically better, safer future - and if we keep pushing, we could lower the amount of global warming we end up with even further. This is huge progress, and we need to celebrate it, even though the fight isn't over.

It's working. Keep going.
