The Impacts of Atmospheric Deposition to the Ocean on Marine Ecosystems and Climate
Bulletin nº Vol 58 (1) - 2009
1
Publish Date: 1 January 2009
The transfer of chemicals from the atmosphere to the ocean has long had an impact on the ocean (e.g. nutrient source; pH influence).
Weather, Climate and the Air We Breathe
Bulletin nº Vol 58 (1) - 2009

Publish Date: 1 January 2009
This theme is particularly appropriate at a time when communities around the globe are struggling to attain the United Nations Millennium Development Goals, especially in terms of health, food, water security and poverty alleviation, as well as to increase their effectiveness in preventing and mitigating natural disasters, of which 90 per cent are directly related to weather, climate and water hazards ...
Implications of Climate Change for Air Quality
Bulletin nº Vol 58 (1) - 2009
1
Publish Date: 1 January 2009
Changes in the chemical composition of the atmosphere, which have resulted from massive industrialization, intensive agriculture and urbanization, as well as road, maritime and air traffic, have led directly and indirectly to enhanced radiative forcing with, as a result, future changes in the Earth’s temperatures and hydrological cycles.
The Carbonaceous Aerosol—a Remaining Challenge
Bulletin nº Vol 58 (1) - 2009
1
Publish Date: 1 January 2009
The ambient aerosol level remains a major challenge in atmospheric science due to its ability to cause negative health effects and its ability to influence the radiative balance and, thus, the Earth’s surface temperature. Our knowledge of the mechanisms by which the effects can be explained, however, is still a matter of ongoing research.

Publish Date: 1 January 2009
In Asian monsoon countries, such as China and India, human health and safety problems caused by air pollution are becoming increasingly serious, due to the increased loading of atmospheric pollutants from waste gas emissions and from rising energy demand associated with the rapid pace of industrialization and modernization.

http://www.mce2.org The Mexico City Metropolitan Area is one of the world’s largest megacities with an estimated 20 million inhabitants living on the dried bed of the elevated lake Texcoco and its surroundings. The inland basin is at an altitude of 2 240 msl and is surrounded on three sides by mountains and volcanoes, with an opening to the Mexican Plateau to the north and a mountain gap to the south-east.

Publish Date: 1 January 2009
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.
