Arctic tundra is now emitting more carbon than it absorbs, US agency says
(theguardian.com)
The Arctic tundra is undergoing a dramatic transformation, driven by frequent wildfires that are turning it into a net source of carbon dioxide emissions after millennia of acting as a carbon sink, the US National Oceanic and Atmospheric Administration (Noaa) said on Tuesday.

Show HN: I built a Iridium/LTE satellite GPS tracker and took it to the Arctic
(github.com/cepa)
One off challenge to build a custom GPS tracker that sends data to cloud over LTE and Iridium networks. Tested successfully on the expedition yacht S/Y Southern Star while crossing Barents Sea from Norway to Svalbard in the Arctics. Built with RockBLOCK 9603N(Iridium), SIMCOM7600G (LTE/GSM) and STM32 microcontroller (ARM,FreeRTOS).
