Subsea Cables Accellerate Africa’s AI Potential
a 48-fibre-pair architecture, a leap in design tailored for high-capacity, low-latency AI workloads. Cable landing stations will transform into AI communication nodes, seamlessly linking African nations’ sovereign AI infrastructure to global data hubs.More AI developments are underway. Google has unveiled plans to build four new subsea cable hubs across African corridors. It’s Equiano system already serves several African countries, and the new projects will serve around 20. Google is also investing $9 million in AI training and research in African universities.Meanwhile, Japan
Google-Backed Coalition to Help Scale Up CO2 Removal
A coalition backed by Google, Stripe and Shopify will spend $1.7 million to buy carbon removal credits from three early stage firms on behalf of the tech giants to help scale up the nascent markets, an executive told Reuters.The world is expected to need to suck between five and 10 billion tons a year of carbon emissions out of the atmosphere by mid-century to reach its climate goals, yet at the moment most technologies are small scale.The coalition, called Frontier, is also backed by H&M Group, JPMorgan Chase and Salesforce, among others.The group, which aggregates demand from its members, will
