Understanding El Niño and La Niña

The video discusses extreme weather events in 1998, attributing them to El Nino, a climate pattern in the South Pacific that occurs every two to seven years. It explains how El Nino and La Nina affect global weather patterns, including trade winds, upwelling, and atmospheric pressure, leading to various weather phenomena like droughts, floods, and hurricanes. The video concludes with a message about the importance of kindness.
