Dage efter at stormen Johannes hærgede det nordlige Sverige, er tusinder af husstande stadig uden strøm, hvilket bryder el-loven, der begrænser uplanlagte afbrydelser til 24 timer. Energimarknadsinspektionen kritiserer selskaberne for dårligt vedligehold og kræver bedre beredskab foran nye storme.
Researchers warn that warming ocean hot spots are fueling more intense hurricanes and typhoons beyond Category 5. These deep-heat regions, expanding due to climate change, have led to over half of the strongest storms occurring in the past decade. Experts call for a new classification to better inform public preparedness.

Scientists at the Institute of Science and Technology Austria have developed a technique using intersecting laser beams to trap and charge single aerosol particles, observing their electrical changes in real time. This method, detailed in Physical Review Letters, mimics processes inside storm clouds and could uncover how lightning initiates. The glowing particles reveal electron loss and sudden charge bursts through a two-photon process.
