Chatbots could one day replace search engines. Here’s why that’s a terrible idea.
Why use oceans to absorb CO2 may not be as easy as expected
The world’s oceans are wonderful carbon sponges, capturing a quarter of man-made carbon dioxide when surface water reacts with greenhouse gases in the air or knocks sea creatures out as they grow.
Some research groups and start-ups want to help accelerate this natural process by adding certain minerals to the oceans that could help them prevent more carbon and slower climate change. This idea has attracted a lot of enthusiasm and investment.
However, numerous recent studies suggest that some of these approaches may not be as effective as scientists had hoped.
That is disappointing news, as a recent report suggests that the world may need to limit its annual additional 10 billion tons of carbon to 2 degrees Celsius by the middle of the century. Read the full story.
