Understanding Catastrophic Climate Events

Catastrophic climate change can lead to severe setbacks for civilization through events such as extreme weather, ocean current breakdowns, and volcanic eruptions. Historical examples include a significant temperature drop in Europe due to ocean current changes and a year without summer following the eruption in 1815. These phenomena can dramatically reduce global food production, with estimates suggesting an 80% chance of severe reduction in the current century. The risk extends to agricultural diseases and pests that threaten staple crops, which are vital for food security.
