Understanding Climate Part 2: Volcanoes, Oceans, and Internal Variability

The video explores internal factors affecting climate, focusing on volcanoes and ocean currents. Volcanoes have a short-term cooling effect due to ash and sulfur dioxide emissions, while ocean currents regulate climate by distributing heat and nutrients. Climate change impacts ocean ecosystems, causing glacier melt and coral bleaching. Internal climate variability, such as the El Nino and Arctic Oscillation, affects weather patterns but not long-term warming trends. The video emphasizes the role of human activity in the planet's energy imbalance and greenhouse gas accumulation.

What are the effects of El Nino and La Nina on global climate?

Describe the Arctic Oscillation and its impact on weather patterns.

What is the primary cause of long-term warming trends observed in recent decades?
