Google calls its new AI model a “virtual satellite.”

Called AlphaEarth Foundations, the model stitches together data from actual satellite images, radar, climate simulations, and more to map Earth’s land and coastal waters.

”The Satellite Embedding dataset is revolutionizing our work by helping countries map uncharted ecosystems - this is crucial for pinpointing where to focus their conservation efforts,” Nick Murray, director of the James Cook University Global Ecology Lab and Global Science Lead of Global Ecosystems Atlas, said in a Google DeepMind blog post.

A tsunami advisory is in effect for the West Coast.

“Stay away from the coast!” the National Weather Service warns. A magnitude 8.7 earthquake off the east coast of Russia has triggered tsunami alerts across the Pacific. The tsunami advisory means that dangerous currents and waves are possible.

Suddenly, the EPA no longer thinks greenhouse gas emissions “endanger” public health.

The Trump administration proposed tossing out the landmark 2009 “endangerment finding” that allows the Environmental Protection Agency to regulate greenhouse gas pollution under the Clean Air Act.

Greenhouse gases including carbon dioxide and methane cause climate change, of course. Climate change is projected to lead to roughly 250,000 additional deaths each year from malnutrition, malaria, diarrhea and heat illness between 2030 and 2050, according to the World Health Organization.

Trump’s AI plan is a massive handout to gas and chemical companies

Google’s investing in a CO2 battery.

It’s part of the company’s new push to support the development of technologies that can store renewable energy for longer periods of time than lithium-ion batteries. It’s the kind of thing that might be able to help Google meet growing data center energy demands and maybe even stop its fossil fuel emissions from continuing to rise.

Breaking down Trump’s big gift to the AI industry

Trump wants everyone using AI — as long as he agrees with what it says.

A new satellite could help improve disaster response.

NASA and the Indian Space Research Organisation plan to launch the satellite on July 30th. The NISAR (NASA-ISRO Synthetic Aperture Radar) mission is supposed to track ice melt and land deformation, helping scientists better understand the impacts of flooding, earthquakes, and more.
