Recently, YouTube user EmperorTigerstar mapped the changing front lines of WWII as it unfolded across Europe. Now, he's finished the job, compiling a timelapse perspective of the entire war that includes the African, Asian, and Pacific theatres.
"Earth is constantly changing. Some changes are a natural part of the climate system, such as the seasonal expansion and contraction of the Arctic sea ice pack. The responsibility for other changes, such as the Antarctic ozone hole, falls squarely on humanity’s shoulders. Our World of Change series documents how our planet’s land, oceans, atmosphere, and Sun are changing over time."
Welcome to the interactive “museum” that takes you on geography journeys. Here you’ll climb a mountain, hover over the Earth, speed across Europe, visit an archeological dig, and even order sushi—plus games, animations, and more!
