“Now onto something that not only shows how … much we humans have impacted our environment. This is a comparison shot of the same place in the Arctic. The first was taken in 1917 and the second in 2020. They show just how much the Arctic ice is melting. Scientists say it’s melting at a rate that’s twice as fast as the rest of the world, with dire consequences for the warming of the planet.”

In these bays also were great quantities of broken ice, which, having been put in motion by the springing up of a northerly wind, were drifted to the southward.”
