The augmented-reality glasses will continue to be sold to businesses rather than directly to consumers....

A reminder: Google Glass was much derided when it launched back in 2013. Since then, it’s faded from public view but has quietly gained a foothold in various industries, including logistics and manufacturing, providing hands-free access to information as people work.

What’s new: The Glass Enterprise Edition 2 has a more powerful processor, a new artificial-intelligence engine, a better camera, faster charging, and better battery life, as well as other updates, Google said in a blog post.

High hopes: Google has moved the product out of its X “moonshot factory” and into its range of products. It’s also built this latest edition of Glass on Android, which it hopes will make it easier for businesses to adopt.

The estimate has been revised upwards because ice sheets in Greenland and Antarctica are melting more rapidly than expected....

New predictions: In 2013, the Intergovernmental Panel on Climate Change predicted that sea levels around the world would rise by between 52 and 98 centimeters by 2100. However, a new study in PNAS by a group of 22 researchers predicts that the real level could exceed two meters, if emissions growth continues along current trends—an outcome they describe as “plausible.”

The impact: This scenario would lead to the loss of 1.8 million square kilometers of land, including critical areas of food production, and displace up to 187 million people.

Complexity and certainty: The study includes some vast ranges of possibilities. The authors say this is because improved understanding of ice loss has increased the bounds of uncertainty. However, they are confident that previous estimates were too conservative.
