Important we keep a close eye on the #Syrian situation, notably what happens to #Rojava & the #Kurds. The #Kurdish people of NE #Syria assembled a fairly egalitarian, multiethnic, #secular #democracy in their autonomous region, but Erdogan and Turkey will be gunning to dismantle it. #defendrojava ❤️⭐
This week I learned that sunsets on Mars are blue (contrasting with the sky during the day, which is pink-yellow-brown). It seems to be due to the exact size and composition of Martian dust particles, which scatter red light in many directions while changing the direction of blue light very little.

Ooookay, so it's been a few months. Some things have happened.

I was accepted into the PhD program at UHI. My program is supposed to start Feb. 3. I'm trying to find a place to live, which is next to impossible.

So I'm throwing this out into the ether because why not? If anyone has ANY leads on a 2+ bedroom flat or house to let in #Orkney, please let me know! I am desperate! We are financially stable and I'm a mature student. We're not smokers.

Please share with your followers. Thanks!

In a meteorological sense, tropical cyclones have a job. The Earth is heated unevenly. This is apparent to almost everyone; the poles (Antarctica and the Arctic) are colder than the tropics. What people don't always realize is that nature always tries to erase gradients. This is loosely related to the second law of thermodynamics, if you will humor me. So Earth is always trying to spread extra tropical heat to the poles, where there are heat deficits.

The way this is done is mainly through ocean currents. Large gyre systems slowly transport heat poleward through steady strong currents, allowing both latent (evaporation and condensation) and sensible (temperature radiation) heat exchange with the much smaller, in terms of energy, atmosphere. During the height of high temperature gradients, for a few months after the solstice, these ocean currents aren't enough. Heat is building up, and the gradient is getting stronger.

That's where hurricanes come in. They are violent transfers of heat from the tropics to the poles. They represent hyper exchange of energy from the oceans to the atmosphere, and eventual poleward movement. The evaporation and mixing while the hurricane is formed takes up ocean energy at the tropics. The intense rain events at higher latitudes (like in North Carolina this year after Hurricane Helene) release that tropical heat to the higher latitudes. That is their job.

The more excess heat we store in tropical oceans, and the less currents can transport heat poleward, the more tropical cyclones we should expect. Nature hates gradients.

“The Japan Meteorological Agency reported that it was the first time since records began in 1951 that so many storms co-existed in the Pacific basin in November.” https://earthobservatory.nasa.gov/images/153575/typhoons-line-up-in-the-western-pacific While I wasn’t affected too much by recent storms / #typhoons (at worst it was just rainy weather), the incoming #ManYi / #PepitoPH is likely the closest to approach #Manila, #Philippines 🇵🇭 . #weather #meteorology #ExtremeWeather #TropicalCyclones

May 2024 wrapped up a stormy, destructive spring for the U.S.

11 billion-dollar disasters have struck the nation so far this year

Life, specifically photosynthesis, made fire possible on Earth, and created fuel to burn.

Today is the 133-year-anniversary of Wounded Knee Massacre. The US Government took their land, broke a treaty and guarantee to give them food and supplies, then sent the U.S. Army, who killed 300 Lakota including 60 women & children😓

The US Govt then:
•Awarded 20 medals of honor to the soldiers guilty of genocide
•Refused to pay reparations or build a memorial
•Waited 100 years to apologize
