US Energy Secretary Jennifer Granholm announced that scientists at the Lawrence Livermore National Laboratory achieved fusion ignition, producing more energy than was used to start the process. The breakthrough is framed as a milestone for national security and a step toward a zero-carbon future. Critics argue the 10-year timeline for commercialization is unrealistic and question the total energy efficiency when accounting for laser power requirements.

Scientists from Lawrence Livermore National Laboratory published a study in Nature Climate Change reaching a "five sigma" level of statistical certainty regarding human-induced global warming. This level of confidence, often called the "gold standard," implies only a one-in-a-million chance that the observed warming is not caused by human activity. Lead author Benjamin Santer's findings were widely reported as a definitive scientific milestone.
