United States
Trump Signs New Travel Ban
Yesterday, U.S. President Donald Trump signed a travel ban targeting citizens of 12 countries, mainly from the Middle East and Africa, and announced travel restrictions for 7 others. Trump imposed this ban due to national security concerns. The restrictions are likely to affect more people than the travel bans imposed during the first Trump administration. The new travel ban is reportedly not applicable to people who already hold U.S. visas, with some exceptions. Trump issued a similar executive order during his first term, shortly after his inauguration in January 2017, banning travel to the U.S. by citizens of seven predominantly Muslim countries. That order faced legal challenges, but a version was ultimately upheld by the U.S. Supreme Court in 2018. U.S. immigration law experts mention that this new travel ban is legally stronger and reflects lessons learned from 2017. In 2024, the State Department granted 170,000 visas to citizens of the countries on the ban list, the majority of which were nonimmigrant visitor visas.

Bulgaria
Bulgaria Allowed to Adopt Euro
On Wednesday, the European Commission approved Bulgaria’s readiness to adopt the Euro as its state currency. When Bulgaria joined the European Union in 2007, they made a commitment to adopting the Euro, but failed to meet the criteria until now. Adopting the Euro reduces the risk of currency crises, gives Bulgaria a seat on the European Central Bank’s rate-setting council, and makes trade and travel within the EU easier. Bulgaria is the EU’s poorest country and support for joining the Eurozone is offset by worry by around 50% of Bulgarians who think joining the Eurozone will erode national sovereignty and economic stability. Bulgaria meets the economic criteria to adopt the common currency on January 1, 2026, but they have to wait for it to be confirmed by a vote of EU finance ministers.

Antarctica
West Antarctic Ice Sheet Tipping
A study published in Communications Earth & Environment warns that very little ocean warming above present-day levels could trigger the collapse of the West Antarctic Ice Sheet (WAIS). A multi-national team of scientists created model simulations going back 800,000 years to understand how the WAIS has responded to past changes in Earth’s climate, as it shifted between cold “glacial” and warmer “interglacial” periods. They found that the WAIS is now in an overshoot state, which should lead to a retreat contributing up to 13 feet (4 m) sea-level rise with little (<0.25 °C) or even no deep ocean warming. Even without additional carbon emissions, 0.25 °C is already likely to occur within the next 50 years, thus resulting in substantial ice loss. The main driver of ice sheet melt and collapse is the rising ocean temperatures around Antarctica. Once the ice sheet tips into a collapsed state, its retreat becomes self-sustaining and practically irreversible without several thousand years of pre-industrial revolution temperatures.
This map depicts grounded ice sheet extent in transient and corresponding equilibrium states for ocean temperatures close to present-day. The top row is for present-day ocean temperature, and the bottom row for a slightly warmer ocean (current temperature +0.25 °C). Click on the map to learn more.

Q: What is the only Latin American country that extends to Polynesia?
A: Chile
Easter Island, or Rapa Nui, is an island and special territory of Chile in the southeastern Pacific Ocean, at the southeasternmost point of the Polynesian Triangle in Oceania. The island is renowned for its nearly 1,000 extant monumental statues, called moai, which were created by the early Rapa Nui people. In 1995, UNESCO named Easter Island a World Heritage Site. By the time of European arrival in 1722, the island’s population was estimated to be 2,000 to 3,000. European diseases, Peruvian slave raiding expeditions in the 1860s, and emigration to other islands such as Tahiti further depleted the population, reducing it to a low of 111 native inhabitants in 1877. Chile annexed Easter Island in 1888. In 1966, the Rapa Nui were granted Chilean citizenship. The 2023 Chilean census registered 8,600 people on the island, with nearly half identifying as Rapa Nui.
