El Niño and La Niña Effects on Global Weather Patterns

The video discusses the extreme weather events of 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 affects global weather by altering trade winds and sea temperatures, leading to various weather phenomena like droughts and floods. The video also covers La Nina, the opposite of El Nino, which results in colder sea temperatures and impacts weather patterns differently. The video concludes with a message on the importance of kindness.
