There are nearly 1.4 million kilometers of submarine cables in service globally. They ensure emails, content, and calls find their way, linking colossal data centers and facilitating worldwide communication. visualcapitalist.com/cp/char… via @visualcap

Charting the Depths: The World of Subsea Cables

Hidden beneath the waves and sprawling along the ocean floor, subsea cables account for approximately 95% of international data transmitted.

No snow left on Longyearbreen, melting all the way to the top of the glacier. Absolute misery here, at 78°N. Lucky we CAN still do something to preserve some ice for future generations. ➡️"Fossil fuels being subsidised at rate of $13m a minute, says IMF" Let's start with that – at Svalbard, Norge
