David Attenborough

Veteran English broadcaster and naturalist. He is best known for writing and presenting, in conjunction with the BBC Natural History Unit, the nine natural history documentary series that form the Life collection. This collection of programmes collectively form a comprehensive survey of animal and plant life on Earth. He is widely considered a national treasure in Britain.

Mount Pinatubo on June 15, 1991

The second largest volcanic eruption of the 20th century which ejected roughly ten billion tons of magma onto surrounding lands and twenty million tons of sulfur dioxide gas. Over the following months, the aerosols formed a global layer of sulfuric acid haze. Global temperatures dropped by about 0.5 °C (0.9 °F) in the years 1991-93, and ozone depletion temporarily saw a substantial increase. The eruption ranked 6 in the Volcanic Explosivity Index (VEI).
