Atmosphere of Earth development of animals. Today's atmosphere contains 21% oxygen, which is great enough for this rapid development of animals. "Air pollution" is the introduction into the atmosphere of chemicals, particulate matter or biological materials that cause harm or discomfort to organisms. Stratospheric ozone depletion is caused by air pollution, chiefly from chlorofluorocarbons and other ozone-depleting substances. The scientific consensus is that the anthropogenic greenhouse gases currently accumulating in the atmosphere are the main cause of global warming. On October 19, 2015 NASA started a website containing daily images of the full sunlit side of Earth on http://epic.gsfc.nasa.gov/. The images are taken
Surface Ocean Lower Atmosphere Study Surface Ocean Lower Atmosphere Study The Surface Ocean Lower Atmosphere Study or Surface Ocean - Lower Atmosphere Study (SOLAS) is an international scientific research initiative that is one of the core projects of the International Geosphere-Biosphere Programme. SOLAS has a goal to achieve quantitative understanding of the key biogeochemical-physical interactions and feedbacks between the ocean and atmosphere, and of how this coupled system affects and is affected by climate and environmental change. Thus, this international project is a critical component to understanding the Earth system and the effects of climate change on this system. The project includes meteorologists, oceanographers, marine
