Five Things We Learned This Week

Week of November 15–21, 2025

⚖️ 1. EU Moves to Limit Big Tech Power

European regulators proposed sweeping rules on Nov 18 to curb dominant tech companies, including stricter data-sharing requirements and restrictions on self-preferencing.

Why it matters: This could reshape how major platforms operate across Europe and force Big Tech to open up more, potentially leveling the playing field for smaller competitors.

🌍 2. COP30 Leaders Agree on New Climate Finance Pledge

On Nov 19, world leaders at COP30 committed to a $150 billion fund over the next five years aimed at helping vulnerable developing nations adapt to climate change.

Why it matters: This may mark a turning point for climate justice by providing crucial resources for countries facing rising seas, extreme weather, and food insecurity.

🔬 3. University Scientists Create Recyclable Batteries with 90% Efficiency

A European research team announced on Nov 20 the development of a new battery design that is both high-efficiency (approximately 90 percent) and made from fully recyclable materials.

Why it matters: If scalable, this could dramatically cut the environmental impact of batteries for electric vehicles and energy storage.

🧠 4. Breakthrough in Early Alzheimer’s Detection

On Nov 21, a biotech company revealed a blood test that can predict early Alzheimer’s disease with over 85 percent accuracy, even before symptoms appear.

Why it matters: Early detection enables earlier interventions, potentially slowing disease progression and improving long-term outcomes.

🛢️ 5. Iran and Saudi Arabia Sign Oil-Export Infrastructure Deal

On Nov 17, Iran and Saudi Arabia signed a historic agreement to jointly develop pipeline and export infrastructure after years of strained relations.

Why it matters: The deal could reshape energy dynamics in the region, ease geopolitical tensions, and potentially affect global oil prices.

This week delivered a rare mix of scientific breakthroughs, political shifts, and geopolitical surprises. Each event hints at broader changes taking shape across the world. As always, the Rowanwood Chronicles will keep watching how these threads unfold in the weeks ahead.

Five Things We Learned This Week

Week of November 8–14, 2025

This week the headlines were shaped by climate urgency, geopolitical shifts and a little cosmic wonder. Below are five carefully date-checked items from Saturday November 8 through Friday November 14, 2025, each with a short note on why it matters and links to the primary reporting.


🌡️ WMO warns that 2023–2025 may be the three hottest years on record

The World Meteorological Organization indicated that the period 2023 through 2025 is on track to be the hottest three-year run in recorded history, raising the risk of climate tipping points and long-term ecological harm. Why it matters: This milestone underlines how far emissions trajectories remain from the 1.5°C goal and increases pressure for urgent action at COP30.

💬 Guterres calls missing 1.5°C a “moral failure” at COP30

U.N. Secretary-General António Guterres used the opening of COP30 in Belém to label the world’s shortfall on the 1.5°C target as a moral failure, urging leaders to treat climate targets as ethical obligations not just technical goals. Why it matters: Framing the target in moral terms aims to push diplomacy beyond incrementalism and into commitments that protect the most vulnerable.

🧲 Putin orders a roadmap to expand rare-earths extraction in Russia

President Vladimir Putin instructed his government to produce a roadmap by December 1 for ramping up rare-earth mineral extraction and building logistics hubs near the Chinese and North Korean borders. The order was reported in early November. Why it matters: Rare earths are essential for electric vehicles, batteries and advanced electronics, so this plan could reshape supply chains and geopolitical leverage.

🔭 Interstellar comet 3I/ATLAS shows complex multi-jet activity

Astronomers released post-perihelion images showing that the interstellar comet 3I/ATLAS displays multiple jets in its coma, offering detailed clues about the composition and behaviour of material from another star system. Why it matters: Detailed observations of an interstellar visitor provide rare insights into the make-up and dynamics of material formed around other stars.

🧬 Small island states demand rich nations “honour” the 1.5°C limit

Leaders from small island and vulnerable states used COP30 platforms to urge wealthier nations to honour commitments around the 1.5°C goal, arguing that temporary overshoots could trigger irreversible harm for their communities. Why it matters: The equity argument is central to negotiations because the countries least responsible for emissions face the gravest consequences.

Closing thoughts: Climate dominated this week in substance and tone. Scientific warnings, moral appeals, and equity demands were front and centre at COP30, while geopolitics and frontier astronomy added texture to the news. These five items remind us that the technical details of policy are inseparable from ethical and strategic choices.
