Last year, we published a map that showed just how long travel took in 1914. Now, there’s a similar map which shows how dramatically things have improved.
Thanks to a super-sensitive new tool, NASA can now see exactly where air pollution is increasing and decreasing — down to the level of neighbourhoods — and in some cases, the results are surprising.
Air travel can be boring, given that it takes absolutely ages to get anywhere. It’s much easier — and strangely hypnotic — to sit at your computer and just watch every single flight over a 24 hour period zip by in under a minute.
