Neptune is cooling down and scientists don't know why

Two decades worth of observations revealed unexpected cooling of the solar system's most distant planet Neptune amid its astronomical summer.

Neptune is orbiting 30 times farther away from the sun than Earth with one year lasting 165 Earth years. The ice giant's seasons, too, last much longer than those on Earth — more than 40 Earth-years each.

As the planet moved into its southern summer over the past two decades, astronomers observed its average global temperatures plummet by a staggering 14 degrees Fahrenheit (8 degrees Celsius).

The observed cooling, however, wasn't uniform, the researchers said in the statement.

Measurements of Neptune's stratosphere, the second lowest layer of the planet's atmosphere, revealed a warming trend above Neptune's south pole. This data set, which only contained data from a two-year period between 2018 and 2020, revealed a speedy warming of about 20 degrees F (11 degrees C). The scientists said that such polar warming has never been observed on Neptune before.

Previous studies suggested there might be a link between the amount of sunspots and Neptune's brightness. The new study also found some evidence of a possible connection between the solar cycle, the brightness of clouds in Neptune's atmosphere and the temperature of its stratosphere.

We Earthenoids are sucking up the heat on purpose to aggravate global warming . . . just to p!$$ off some Libtards. . . .

Not quite a “Hoot and the holler” in distance.

Massive, short term warning. But i think it was caused by chili dog night.

The energy cyles of the sun and one of it’s orbiting planet’s climate cycles, a connection? Nah, impossible!!!! /sarc

[al_c]

Human-caused climate change ... duh.

[jmacusa]

The gas giants like Neptune and Uranus have liquid water oceans or water ice beneath their atmosphere's. But they're both uninhabitable for us.

Geeze, Biden’s war on gas and oil has now reached Neptune ... saw a pic of Neptune and right next to it was one of the huge Biden “I did that” stickers.

Thanks BenLurkin.

It’s anthropomorphic global warming. Obviously.

But this time, it's really anthropomorphic Neptune cooling; fire up the SUVs!

[Robert DeLong]

No humans creating excessive CO2. /sarcasm

Neptune is cooling down and scientists don't know why

Maybe he’s not mad anymore. A guy can’t stay ticked off forever, you know.

[Rebelbase]

Venus is a hot as ever so Neptune must be turning gay if he’s cooling off.

[JimRed]

The rest of Monmouth County (NJ) is cooling down, too. Not just Neptune!

"Neptune is cooling down and scientists don't know why"

Yet they delude themselves that they can tell to a scientific certainty that cow farts cause global warming.

Neptuneons are driving around in their version of SUV’s.

Earth, in its planetary arrogance, is stealing Neptune’s warmth. Earth superiority. We need to defeat Earthness.

unexpected cooling of the solar systems most furthest planet...

smmfh....
