Upbeat and Downstairs: Home of Daryl C. DuLong

Today is Earth Day, and in addition to turning off unnecessary lights, drinking less bottled water, and switching to biodegradable clothing (watch out for rain storms!), it is also an excellent day to become a bit more educated on the perpetual dialogue about climate change.

One aspect of the discussion is the level of carbon dioxide in our atmosphere — grouped in as one of the “greenhouse gases” — and how it has been rising steadily. If nothing else, use today as an excuse to learn how to reverse the trend:

On a slightly less serious note, in celebration of Earth Day, NASA presents images of Earth captured by cameras aboard the International Space Station. Traveling at an approximate speed of 17,500 miles per hour, the space station orbits Earth every 90 minutes from an altitude of approximately 220 miles, and can be seen from Earth with the naked eye. Its crew experiences 16 sunrises and sunsets each day.
