1/ Cuba is out of fuel, strangled by the US fuel chokehold. People are dying, systems are breaking down. This is collective punishment against a people who have done absolutely nothing except live their lives under hard conditions imposed by the US blockade for decades.

I was lucky to get to teach Juniper in two of her classes, and had just written her reference letters for the summer. It's hard to express what a loss this has been for our community. I'll always remember coming down the stairs to class and finding her joyfully practicing singing in the stairwell.

The Voting Rights Act is essentially dead and it’s quite possible that we will, like when a similar SCOTUS gutted civil rights at the fall of Reconstruction, see a disappearance of much of the Black congressional representation, especially in the most heavily Black states, which are in the South.

Dropsite reports “Black rain” + “nuclear winter” caused by Israeli strikes on oil depots in Tehran - chemicals are producing acidic precipitation that causes skin burns + severe lung damage on contact - the rain is corrosive + could damage structures - heavy metals leaking into soil/water systems
💢 “Black rain” and “nuclear winter” effect reported in Tehran after Israeli strikes on oil facilities

▪️ Israeli strikes on oil depots around Tehran have released massive quantities of toxic hydrocarbons, sulfur dioxide, and nitrogen oxides. Mixed with rainwater, these chemicals are causing highly acidic precipitation that can cause skin burns and severe lung damage upon contact, according to Iranian authorities.

▪️ Dense plumes of black smoke from the Shahran and other refineries have blotted out the sun, plunging parts of the city into darkness and creating a "nuclear winter" effect, NYT reported. Authorities warned that these noxious fumes cause acute respiratory distress and eye irritation.

▪️ Oil-saturated rainwater has blanketed the city, leaving rooftops, balconies, and streets covered in a thick, murky black liquid and oily soot. This contamination poses a long-term risk of heavy metals like nickel and vanadium leaching into the soil and local water systemsEnvironmental groups warn the pollution threatens migratory birds crossing the Persian Gulf. The "black rain" and smoke plumes can cause internal organ damage and destroy the insulating properties of bird feathers, leading to hypothermia and death.

The Iranian Red Crescent Society warned of the dangers of the rain, advising residents to protect themselves and to cover exposed food from oily soot particles. Officials said the rain is highly corrosive and could potentially damage civilian structures.

🇨🇺 February 13 | The UN Office of the UN High Commissioner for Human Rights (OHCHR) expressed extreme worry over the “deepening socio-economic crisis” in Cuba, highlighting several key issues:

▪️ With over 80% of water pumping on the island dependent on electricity, power cuts are undermining access to safe water, sanitation, and hygiene.

▪️ Decades-long U.S. embargo and recent oil shipment restrictions are responsible for compounding economic strain.

▪️ Fuel shortages are also jeopardizing hospitals, including ICUs and emergency rooms, and disrupting the storage and delivery of vaccines and other temperature-sensitive medicines.

▪️ The rationing system and basic food basket have been disrupted, affecting school meals, maternity homes, nursing homes, and other social protections.

▪️ Vulnerable groups are being hit hardest.

▪️ Electricity cuts are also limiting communications and access to information.

👉 OHCHR urged all states to lift unilateral sectoral measures, saying policy goals cannot justify actions that violate human rights.
