Understanding Climate Part 1: Orbital Variations and the Sun
With the scale of ecology now understood, we can start to look at one of the most important concepts in ecology, climate. What is climate? How does it differ from weather? How does climate change over time and why? Let's do a deep dive now!

This movie shows the Sun from the two STEREO spacecraft using the 171 Angstrom filter in the Extreme UltraViolet Imager (EUVI).
The 171 filter reveals ionized iron (Fe+8=Fe IX, Fe+9=Fe X), which forms at temperatures above 1,300,000K, and flows along the magnetic field lines of the solar active regions
