Howmet slides after Elon Musk unveils SpaceX turbine-blade casting plan

Tesla CEO Elon Musk has sounded a stark warning, stating that humanity must act within the next 50 years to avoid irreversible environmental catastrophe. While Musk acknowledges that transitioning to sustainable energy is crucial, he argues that this alone may not suffice to prevent the worst impacts of climate change.

Drawing on ambitious plans for space-based geoengineering, Musk suggested that deploying "sentient satellites" at Earth-Sun Lagrange points could one day regulate the planet's temperature. These solar-powered AI satellite constellations, he envisioned, could potentially regulate the amount of solar energy reaching Earth for up to 1 billion years.

However, Musk made clear that this technological solution is not a panacea, warning that "space satellites to control temperature and massive geo-engineering will be needed or it will be game over."

Musk emphasized the urgency of action, noting that humanity has around 50 years to address the looming threats. He pointed to the escalating risks for vulnerable coastal populations as evidence of the pressing nature of the situation. His comments come amidst mounting evidence of sustained global warming, with climate data indicating that 2025 was the third-warmest year on record, approximately 1.44°C above the average temperature between 1850 and 1900.

The warning from Musk also aligns with growing concerns over cuts to U.S. climate research funding. Recently, the Trump administration announced the discontinuation of support for the Arctic Report Card, an annual assessment that tracks changes in the rapidly warming Arctic. This move, among others that have scaled back climate research efforts, has drawn criticism from officials who argue that such actions are alarmist and counterproductive in the fight against climate change.
