(Image credit: Stephen Lam/San Francisco Chronicle via Getty Images)The world's climate is more out of balance than at any time in recorded history, the UN's weather agency said in a dire warning today.We already know that human-released carbon emissions blanket Earth's atmosphere and increasingly trap more solar radiation than can be reemitted back into space, creating an imbalance that heats the planet. But a new report by the World Meteorological Organization (WMO) has revealed that this process is happening faster than any time in history, with 2025 beating the previous record set the year before.Much of the excess heat, roughly 91%, was absorbed by the oceans; another 5% heated the land; 3% went into ice and 1% into the air. The spillover effects of this planetary heating are also becoming more pronounced. This month alone there has been snow in Alabama, a record-shattering heatwave across the West, and flooding that has prompted evacuations in Hawaii.The trend NASA's Artemis II rocket rolls toward Launch Pad 39B at the Kennedy Space Center in Cape Canaveral. (Image credit: Gregg Newton / AFP via Getty Images)NASA's Artemis II moon rocket is back on its launchpad as the space agency makes a final bid to launch the spacecraft before its April deadline.This is the second time that the 322-foot-tall (98 meters) Space Launch System and Orion capsule stack has rolled out to the launchpad this year, the first having taken place on Jan. 17. But following two wet dress rehearsals and two leaks, NASA decided to wheel the rocket back to the Vehicle Assembly Building for repairs.NASA is expected to announce further tests, including a wet dress rehearsal, this week. If the fixes have worked as planned, the rocket could blast off as early as April 1.Three to readA new twist on matter?
