El fechamiento por radiocarbono es un pilar de la climatología y la arqueología. Sin embargo, esta metodología se encuentra amenazada por las emisiones de combustibles fósiles, que invalidan una señal útil proveniente de pruebas nucleares.
Radiocarbon dating is a cornerstone of climate and archaeological sciences. But the method is under threat as fossil fuel emissions negate a useful signal from atomic tests.
Model simulations of the impact of a large-scale nuclear war reveal long lasting effects with much of the ocean not returning to pre-war levels despite the cessation of the initial cooling.
Shock waves from Cold War era nuclear tests gave seismologists a glimpse of the inner core. Its wobbly rotation could explain phenomena such as the periodic change in the length of a day.
On the 75th anniversary of the Doomsday Clock, major threats against the world have not waned, say organizers.
A nuclear war would claim many lives from its direct impacts and cause rapid climate change that would further imperil humanity. Scientists can help shape policies to put us on a safer path.
Una sacudida al sistema climático provista por una guerra nuclear podría provocar un fenómeno de el Niño como nunca habíamos visto.
Nuclear bomb tests conducted during the Cold War turned an idyllic tropical isle into a radioactive ship graveyard.
A jolt to the climate system provided by nuclear war could spur an El Niño like we’ve never seen before.
The dual threats of nuclear warfare and climate change move the needle to 100 seconds to midnight.
