Curfew in Downtown Los Angeles
Yesterday the mayor of Los Angeles declared an overnight curfew in an area of the downtown district, in force between 8:00pm and 6:00am, local time. Officials said the curfew is in response to businesses being vandalized and looted, including 23 looted on Monday night. The curfew covers a 1 square mile (2.5 km sq) area, including an area that has seen consistent protests since Friday. L.A. police have made “mass arrests” after five consecutive days of unrest and protests in response to President Donald Trump’s growing immigration raids. Immigration raids have continued to take place, as National Guard troops have been deployed to protect border control agents carrying out enforcement operations. In total, President Trump has sent 4,000 National Guard and 700 Marines to Los Angeles.

Colombia
Bomb Attacks Kill Seven
Twenty-four coordinated bomb and gun attacks devastated Colombia’s southwest on Tuesday, killing at least 7 people. Civilian targets, police posts, and municipal buildings were all attacked in Cali, Colombia’s third-largest city, and in the neighboring provinces. Authorities suspect the car bombs and rifle fire are the work of the Central General Staff (FARC-EMC), one of the largest guerrilla groups in Colombia. In a Tuesday statement, FARC-EMC warned the public to avoid military and police installations, but did not claim responsibility. In the last ten years, Colombia’s government has struggled to contain violence and has been unable to reach a peace deal with FARC-EMC and other armed groups. These attacks come on the heels of the attempted assassination of presidential candidate Miguel Uribe Turbay last Saturday. Many Colombians fear a return to the bloody violence that plagued the 1980s and ’90s, when political assassinations and cartel attacks were commonplace.

World
Ocean Acidification Worsens
Researchers writing in Global Change Biology have found the acidification of deep oceans passed a critical threshold five years ago, earlier than previously believed, jeopardizing their role in supplying food and oxygen to the surface. In 2023, researchers reported that six of the nine planetary boundaries, a series of climate change milestones indicating planetary health, had been crossed, and issued a red alert for ocean acidification, which is measured by the saturation of aragonite in surface waters. These new findings show that the threat to marine ecosystems worldwide is far more extensive than previously understood. Approximately 60% of the global subsurface ocean (down to 656 feet or 200 meters) and over 40% of the surface ocean have exceeded the acidification threshold set in 2009. These changes threaten key species such as coral reefs, polar pteropods, and coastal bivalves. Significant impacts are being observed in the deep waters off the coast of western North America, which support extensive salmon and crab fisheries. The main driver of acidification is carbon dioxide from fossil fuel burning.
This map depicts the percentage drop in surface aragonite saturation (ΩArag) from 1750 to 2020, a key marker of ocean acidification, with the black line marking a 20% decline. Click on the map to learn more.

Q: Where is the largest earth-filled dam in the world located?
A: Pakistan
Tarbela Dam is an earth-filled dam along the Indus River in Pakistan’s Khyber Pakhtunkhwa province. It is the largest earth-filled dam in the world. Positioned where the Indus River emerges from the foothills of the Himalayas and enters the Potwar Plateau, the dam features a reservoir for water storage. Tarbela Dam was constructed as part of the Indus Basin Project after signing of the 1960 Indus Waters Treaty between India and Pakistan. The purpose was to compensate for the loss of water supplies of the eastern rivers (Ravi, Sutlej and Beas) that were designated for exclusive use by India per terms of the treaty. The dam was completed in 1976 and was designed to utilize water from the Indus River for irrigation, flood control, and the generation of hydroelectric power by storing flows during the monsoon period while subsequently releasing stored water during the low flow period in winter.
