Antarctic ozone hole maximum size, 1979-2015. Ozone concentrations are colour-coded, with the purple and dark blue areas representing the lowest levels, constituting the "hole". The hole was first detected in mid 1970s, and was found to be due to chemical reactions between the atmosphere and chlorofluorcarbon gase...

produced by Science Photo Library (London, England: Science Photo Library, 2009), 2 mins
Animated models of the projected polar atmospheric ozone levels from 1974 to 2065, had CFCs (chlorofluorocarbons) not been banned. Ozone levels range from high (red) to zero (dark blue) here, and vary seasonally, being most depleted in the spring in each hemisphere. Use of CFCs was banned by the Montreal Protocol...

Animation of the formation and effects of acid rain. Acid rain occurs when pollutant gases emitted from industrial processes react with water in the atmosphere, forming acids. These dissolve in rain water and fall to the ground, where they have numerous detrimental effects. The power plants and vehicles seen here...

Global temperature differences from 1880 to 2007. Dark blue areas show regions where the temperature was cooler then the average temperature. Red areas show regions where the temperature was warmer then the average. The data reveal that average temperatures have warmed in the last years of the 20th century.

Global temperature changes, 1850-2000. Animated graph showing the trend in global surface temperature changes between the years 1850 and 2000. The graph shows both the observed temperature change (red line) and the changes as predicted by a climate change simulation (green line). This simulation models changes due...
