Air pollution layer, timelapse
See details
produced by Science Photo Library (London, England: Science Photo Library, 2014), 25 secs
Timelapse footage of strong winds blowing clouds above and air pollution below. The pollution forms a visible layer above the ground. The source of this pollution is the city of Denver, Colorado, USA. The strong northerly winds associated with a cold front are blowing the pollution back to its source. Filmed in Co...

Antarctic ozone hole, 1979-2015
See details
produced by Science Photo Library (London, England: Science Photo Library, 2016), 1 min
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...

Cyanobacteria bloom in a lake
See details
produced by Science Photo Library (London, England: Science Photo Library, 2014), 28 secs
Bloom of cyanobacteria (blue-green algae) at the edge of a lake. Blooms such as this may be caused by fertiliser runoff. Some cyanobacteria produce toxic chemicals, and such blooms can severely impact other life in the lake.

Earth after 70-metre sea level rise
See details
produced by Science Photo Library (London, England: Science Photo Library, 2012), 1 min
Animation of the Earth showing the effects on the landmasses of a sea level rise of 70 metres. The familiar outlines of the continents are drastically altered in this scenario. It has been calculated that the complete melting of the Greenland and Antarctica ice sheets would cause such a rise, with Greenland contri...

Ozone depletion without CFC ban
See details
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...

produced by Science Photo Library (London, England: Science Photo Library, 2015), 2 mins
Slow terrestrial carbon cycle. Animation of some of the processes that form the terrestrial geological and industrial carbon cycle, part of the larger overall carbon cycle for the whole Earth. This part of the cycle sees the carbon taken up by trees and other plants accumulate on the ground as they die. Over long...

Formation and effects of acid rain
See details
produced by Science Photo Library (London, England: Science Photo Library, 2015), 2 mins
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 changes
See details
produced by Science Photo Library (London, England: Science Photo Library, 2008), 16 secs
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.
