Nicolas Magand on the internet

Comments about tech, media, nature, &c.

My name is Nicolas Magand and I live in Paris, France. I work as a social media and engagement editor at the Global Editors Network, a non-profit aimed at promoting innovation and sustainability in the news industry. Here I blog mostly about tech and media, but many other topics can face my enthusiasm.

Incredible depiction of the asteroid that wiped off more than 75% of Earth species

Jason Kottke shared some hard-to-wrap-your-head-around facts, extracted from the book The Ends of the World by Peter Brannen:

A rock larger than Mount Everest hit planet Earth traveling twenty times faster than a bullet. This is so fast that it would have traversed the distance from the cruising altitude of a 747 to the ground in 0.3 seconds. The asteroid itself was so large that, even at the moment of impact, the top of it might have still towered more than a mile above the cruising altitude of a 747. In its nearly instantaneous descent, it compressed the air below it so violently that it briefly became several times hotter than the surface of the Sun.

And this one:

[…] in the Yucatan it would have been a pleasant day one second and the world was already over by the next.

Stronger chance of me buying the book than to go to the theater watch yet another movie with featherless dinosaurs.

Chilling facts about air conditioning

Lily Strelich, on the June 14th Quartz Obsession newsletter, on the theme of air conditioning:

Most A/C units rely on refrigerants like hydrofluorocarbons, which are potent greenhouse gasses. Carbon emissions from cooling have tripled since 1990, contributing to the warming climate, which in turns requires more air conditioning. Cool the room, warm the globe, repeat.

This points me to the fact that there has been a lot of – deserved – coverage on the impacts of cars and transportation on climate change, but I've found many people pretty clueless when it comes to energy consumption in general. Filling up the whole kettle for a single cup of tea, or turning the heater up before wearing a sweater are somehow less criticised behaviors than leaving the car engine run while waiting for a friend to come down.

If you are not a subscriber of the Quartz Obsession newsletter, you're missing out on a great source of daily facts; a good game to play with your colleagues is guessing the topics every day before the newsletter arrives.
