Fast-growing urbanisation, environmental deterioration and climate change are making individuals, organisations and businesses more vulnerable to meteorological and environmental hazards. Modern life requires detailed knowledge about our immediate personal environment – the climate and weather as well as the air, water and soil quality – at work, home or play, may we be indoors or out.

As atmospheric CO 2 continues to increase, more and more CO 2 enters the ocean, which reduces pH (pH is a measure of acidity, the lower the pH, the more acidic the liquid) in a process referred to as ocean acidification. Declines in surface ocean pH due to ocean acidification are already detectable and accelerating.

The Montreal Protocol on Substances that Deplete the Ozone Layer, signed in 1987, has been successful in that the amount of chlorofluorocarbons is now slowly diminishing. A common misunderstanding, however, is the belief that the ozone problem has been solved and the ozone layer is back to its original state.
Observing the Global Atmosphere by Instrumented Passenger Aircraft – The Story of IAGOS

Publish Date: 3 November 2014
The In-service Aircraft for a Global Observing System (IAGOS) uses commercial passenger aircraft as a platform for the measurement of the composition of the atmosphere. It is one component of the European Research Infrastructure for gathering long-term, routine in-situ observational data on the state of the atmosphere.

How severely will climate change affect different regions the United States? It depends on climate policy, says new research by the MIT Joint Program on the Science and Policy of Global Change. The US National Climate Assessment, released this spring by the White House, describes a troubling array of climate woes, from intense droughts and heat waves to more extreme precipitation and floods, all caused by climate change.

For 50 years, since Dave Keeling started monitoring carbon dioxide at Mauna Loa, Hawaii, and the South Pole, scientists have been tracking greenhouse and other trace gases in the global atmosphere. The results have revolutionized our understanding of biogeochemistry and demonstrated that human activities affect climate change and air quality.
