Climate Crisis Has Tripled Length of Deadly Ocean Heatwaves, Study Finds

2 months 2 weeks ago
The climate crisis has tripled the length of ocean heatwaves, a study has found, supercharging deadly storms and destroying critical ecosystems such as kelp forests and coral reefs. From a report: Half of the marine heatwaves since 2000 would not have happened without global heating, which is caused by burning fossil fuels. The heatwaves have not only become more frequent but also more intense: 1C warmer on average, but much hotter in some places, the scientists said. The research is the first comprehensive assessment of the impact of the climate crisis on heatwaves in the world's oceans, and it reveals profound changes. Hotter oceans also soak up fewer of the carbon dioxide emissions that are driving temperatures up. "Here in the Mediterranean, we have some marine heatwaves that are 5C hotter," said Dr Marta Marcos at the Mediterranean Institute for Advanced Studies in Mallorca, Spain, who led the study. "It's horrible when you go swimming. It looks like soup." As well as devastating underwater ecosystems such as sea grass meadows, Marcos said: "Warmer oceans provide more energy to the strong storms that affect people at the coast and inland."

Apple To Analyze User Data on Devices To Bolster AI Technology

2 months 2 weeks ago
Apple will begin analyzing data on customers' devices in a bid to improve its AI platform, a move designed to safeguard user information while still helping it catch up with AI rivals. From a report: Today, Apple typically trains AI models using synthetic data -- information that's meant to mimic real-world inputs without any personal details. But that synthetic information isn't always representative of actual customer data, making it harder for its AI systems to work properly. The new approach will address that problem while ensuring that user data remains on customers' devices and isn't directly used to train AI models. The idea is to help Apple catch up with competitors such as OpenAI and Alphabet, which have fewer privacy restrictions. The technology works like this: It takes the synthetic data that Apple has created and compares it to a recent sample of user emails within the iPhone, iPad and Mac email app. By using actual emails to check the fake inputs, Apple can then determine which items within its synthetic dataset are most in line with real-world messages.
