Deep Frozen Arctic Microbes Are Waking Up
An anonymous reader shares an opinion piece from Scientific American: Permafrost covers 24 percent of the Earth’s land surface, and the soil constituents vary with local geology.

Internet Archive Adds Fact Checks To Explain Web Page Takedowns
AmiMoJo writes: Fact checking is increasingly a mainstay of the modern internet, and that now includes “dead” web pages. The Internet Archive has started adding fact checks and context to Wayback Machine pages to explain just why they were removed. If a page was part of a disinformation campaign or pulled due to a policy violation, a conspicuous yellow banner will…
The Arctic hasn’t been this warm for 3 million years
The last time CO2 concentrations reached today’s level was 3 million years ago, during the Pliocene Epoch. Hear from geoscientists who see evolving conditions in the Arctic as an indicator of how climate change could transform the planet. Source: https://earthsky.org/earth/arctic-warmest-3-million-years…
Amazon Launches Program To Pay Consumers For Their Data On Non-Amazon Purchases
An anonymous reader quotes a report from TechCrunch: Amazon has launched a new program that directly pays consumers for information about what they’re purchasing outside of Amazon.com and for responding to short surveys.
