Dear MEL Topic Readers,
Nasa timelapse paints 'most complete picture of life' to date
Threats to the environment are no new news. Greenhouse gas emissions, plastic waste, water pollutions just to name a few. When you see photos of the smog-clogged city like Delhi, plastic particles floating in the sea, or grossly contaminated water being drained into a river, you understand how serious the problems are. Yes, seeing is believing.
Then how can climate changes be visualized? There have been numbers of images of shrinking ice sheets, melting glaciers, and expanding deserts. But is there one that shows such changes more comprehensively and extensively at a glance?
Yes. Nasa has recently released a time-lapse video that shows how ice, forests, deserts, and inhabited and developed places changed over the course of the last two decades. The images that are shown in the video look similar to the ones shown by functional MRI (fMRI).
Enjoy watching the video to find how the earth has been breathing for 20 years.
