The phenomenon that makes stars shine and hydrogen bombs explode has yet to be reliably tamed for energy generation. But that isn’t stopping companies from trying.

Mitigation alone is no longer enough because, even if we stopped all emissions today, the carbon dioxide released to date would continue warming the planet for generations. www.nrdc.org/bio/jackie-w...

As a giant swell of warm water advances toward South America, air masses over the central and eastern equatorial Pacific begin to heat, causing convective air to rise, and over the Indian ocean, to sink: the pattern of El Niño's onset, as shown in the latest ECMWF forecast.

As of mid-2026, the Atlantic Meridional Overturning Circulation (AMOC) is in a state of continued, long-term weakening due to climate change, with expert consensus shifting toward a higher risk of a potential, non-linear collapse by the end of the century. NASA.

Deep-diving robots help crack the mystery of Antarctica’s vanishing sea ice
Ten years ago, Antarctica's sea ice suddenly and dramatically declined. Scientists now blame a "very violent release" of deep, pent-up heat.
