Google Pivots to Nuclear Reactors to Power Its Artificial Intelligence

Posted by in categories: climatology, nuclear energy, robotics/AI

Google on Monday signed a deal to get electricity from small nuclear reactors to help power artificial intelligence.

The agreement to buy energy from reactors built by Kairos Power came just weeks after word that Three Mile Island, the site of America’s worst nuclear accident, will restart operations to provide energy to Microsoft.

“We believe that nuclear energy has a critical role to play in supporting our clean growth and helping to deliver on the progress of AI,” Google senior director of energy and climate said during a briefing.

Could injecting diamond dust into the atmosphere help cool the planet?

Posted by in category: climatology

A multi-institutional team of climatologists, meteorologists and Earth scientists has found evidence that dropping diamond dust from an airplane into the atmosphere could cool the planet. In their study published in the journal Geophysical Research Letters, the group used 3D climate models to compare aerosols that might be used to cool the planet.

The role of the scientist in a post-truth world

Posted by in categories: climatology, geoengineering

So people can change the weather, and science-based weather modification techniques are now employed in over 50 countries according to the World Meteorological Organization. But for every science-based weather-altering technique, there are dozens of pseudoscientific urban legends.

In Cuba, it is believed that a shotgun can stop twisters. Aim at the funnel cloud, pull the trigger, and stop the tornado or waterspout before it touches down. In Puerto Rico, people have suggested installing giant fans in the El Yunque rainforest on the east side of the island to blow hurricanes away. Others have suggested putting fans in Africa to increase the amount of Saharan dust that already enters the Atlantic early in hurricane season, which can dampen fledgling tropical storms. The proposal to tow icebergs from the Arctic down to the tropical ocean to cool it down is equally impractical. No flotilla could bring enough rapidly melting icebergs to cool the vast tropical Atlantic Ocean for the six months of hurricane season.

Given all these fantastical ideas perhaps it should come as no surprise that besides altering the weather, conspiracy theorists also claim HAARP can trigger earthquakes, and, as the Georgia men believed, remotely control minds. The line between harmless urban legend and dangerous conspiracy theory is thin.

What happens to the Climate when Earth Passes Through Interstellar Clouds?

Posted by in categories: climatology, space travel

Noctilucent clouds were once thought to be a fairly modern phenomenon. A team of researchers recently calculated that Earth and the entire solar system may well have passed through two dense interstellar clouds, causing global noctilucent clouds that may have driven an ice age.

The event is thought to have happened 7 million years ago and would have compressed the heliosphere, exposing Earth to the interstellar medium.

Interstellar clouds are vast regions of gas and dust between the stars within galaxies. They are mostly made up of hydrogen along with a little helium and trace elements of heavier elements.

SpaceX Launches Hera Planetary Defense Mission, Narrowly Escaping Hurricane Milton

Posted by in categories: climatology, space travel

SpaceX undertook a planetary defense mission on behalf of the European Space Agency (ESA) on Monday, aiming to provide scientists with tools to prevent future catastrophic cosmic impacts.

The ESA’s Hera planetary defense mission builds on NASA’s 2022 Double Asteroid Redirection Test (DART) mission and will analyze its effects, allowing scientists and engineers to gain a more comprehensive understanding for use in real-world emergencies.
