Welcome back to The Cosmic Companion! This week, we kick off a new series, Why Explore Space? As we discuss how space travel and exploration are essential to help monitor and cure the effects of global climate change.

Later on in the show, we are going to be talking with Alan Gratz. His new book, Two Degrees, is a young adult novel exploring the effects of catastrophic climate change around the world.

Since the earliest days of the human race, people have been attempting to predict the weather. Such prognostications were essential for planting, hunting, and other reasons.

The realization that climate is vital to understanding weather took quite a while for scientists to understand. And, the climates of Earth have changed over time, and will continue to change in the future.

From the time of the Ancient Greeks, people have discussed the idea that human actions could change environmental conditions on Earth.

By the 19th Century, researchers had started to realize, for the first time, that human activities — notably the consumption of fossil fuels — had started to alter the atmosphere of Earth, adding to the CO2 which naturally envelopes our planet.
