Volcanoes' Harmful Vaping
Scientists have now determined that the underwater volcanic eruption in Tonga earlier this year delivered an astonishing 160,900 tons of water vapor to the stratosphere — water vapor that could intensify global warming for years to come, reports Harry Baker for Live Science. This year's Tonga eruption also cracked open some mysteries about Earth's past volcanic events. Back in 1883, a volcano on the island of Krakatoa erupted and caused worldwide tsunamis — just as the recent Tonga eruption did. This time, however, geophysicists were finally able to learn how volcanic eruptions cause tsunamis on that global scale, as Robin George Andrews reported for Quanta.
You Are Not the Supreme
In 2019, Google announced that they had achieved quantum supremacy with a calculation that no ordinary computer could match. Researchers in China have now shown that an ordinary computer can do it within hours, reports Adrian Cho for Science. Google's claim was controversial from the start. Researchers at IBM and others rejected that Google had proved true quantum supremacy, as Kevin Hartnett covered for Quanta in 2019. | |
