Musk Says Humanity Has 50 Years to Act on Climate or Face Extinction

Elon Musk has warned that humanity must take decisive climate action within the next 50 years or risk catastrophic consequences. He argued that transitioning to sustainable energy alone will not be enough to address the scale of threats facing Earth's climate. Musk proposed using space satellites to help regulate the planet's temperature as a long-term solution spanning billions of years. He framed the urgency around the geological reality that mass extinction events occur approximately every 100 million years.
