9 Lesser-known global warming facts

Whether you believe it or not, the fact of the matter is, the world is experiencing climate change. In the past two decades alone, we’ve experienced evitable climate change if we just prepared and took the signs seriously when they first materialized. The increasing industrialization of the world drives demands like no other, which in turn, is the result of the increasing population. This alone is a major precedent of climate change.

To explain her cause, Calandrelli used the popular “Joey, the famous ‘Friends’ character being taught French” meme, where Phoebe hopelessly tries to teach Joey French.

Capturing a Satellite (November 1984)

An amazing image titled “Capturing a Satellite” by NASA: Astronaut Dale A. Gardner prepares to dock with the spinning WESTAR VI satellite during the STS-51A mission. He was wearing a getting his turn in the Manned Maneuvering Unit (MMU, see notes 1). Gardner used a large tool called the Apogee Kick Motor Capture Device to enter the nozzle of a spent WESTAR VI engine and stabilize the communications spacecraft sufficiently to capture it for return to Earth in the cargo bay of the Space Shuttle Discovery.
