Arctic ice is disappearing — the question is how fast. Summer sea ice could endure 100 more years, or it could vanish later this decade, with disastrous consequences for the rest of the planet. To nail down the answer, an expedition to the top of the world has to untangle the knotty physics of ice.
A state-of-the-art supercomputer simulation indicates that a feedback loop between global warming and cloud loss can push Earth's climate past a disastrous tipping point in as little as a century.
The noted mathematician and author Steven Strogatz explains why he wanted to share intimate conversations with leading researchers from diverse fields in his new Quanta Magazine podcast.
The latest AI algorithms are probing the evolution of galaxies, calculating quantum wave functions, discovering new chemical compounds and more. Is there anything that scientists do that can't be automated?
