Earth Hour takes place tomorrow, March 25th, 2017 at 8:30-9:30PM local time. Earth Hour is when people (and organizations) around the globe switch off their lights to show support for the need to take action on climate change. Unfortunately, capturing imagery of the event from space would be almost impossible. The ‘Earth City Lights’ layer is relatively low resolution and created from a large number of images over time. It’s a pity, because an animation of Earth Hour would be interesting given the complicated time zones of the earth.

Given that Earth Hour is about action on climate change, today we are having a look at some recent news from the National Snow and Ice Data Center (NSIDC) in Boulder, Colorado. Apparently 2017 saw a new record minimum for sea ice cover. This includes the smallest ‘maximum sea ice cover’ on record for the Northern Hemisphere and the smallest ‘minimum sea ice cover’ for the Southern Hemisphere.

We couldn’t find a KML for 2017 data, but the NSIDC does provide KMLs for 1979-2016 which you can find here.
