The video discusses various methods of measuring climate change, such as thermometers placed in different environments. It highlights the shrinking of ice and glaciers, and the impact of warming on plants and animals. The distinction between weather and climate is explained, noting that short-term weather events do not negate long-term warming trends. Natural phenomena like La Nina and volcanic eruptions can temporarily affect climate. Long-term data, typically averaged over 30 years, consistently shows a warming trend.
