What does C&E mean in NASA

Global warming is largely caused by the release of certain gases, such as carbon dioxide, into the Earth's atmosphere. These gases are known as greenhouse gases because they trap heat and cause our planet to warm up. Human activities, such as burning fossil fuels for energy, are responsible for most of the greenhouse gas released in our atmosphere.

Global warming affects the environment in many ways. As temperatures rise, glaciers and ice sheets rapidly melt; sea levels increase; ocean currents and weather systems are disrupted; plants and animals experience disruption of their habitats and food sources; extreme weather events become more frequent; coral reefs bleach out due to rising ocean temperatures; and water shortages become common in places with inadequate infrastructure for managing water supplies.

Air pollution is mainly caused by human activities such as burning fossil fuels for energy production and transportation. Other sources of air pollution include deforestation, wildfires, industry processes that release pollutants into the air, and agricultural activities like livestock farming which emits methane gas into the atmosphere.

Air pollutants can have negative impacts on human health through health risks arising from long-term exposure to toxic chemicals or from short-term exposure to high concentrations of harmful particulate matter in smoke or smog. Chronic illnesses such as respiratory diseases can be developed over time if exposed to contaminated air on a regular basis. Acute illnesses may also arise from short-term exposure to high concentrations of polluted air or hazardous substances in smoke or dust particles. In extreme cases, exposure to pollutants can also lead to death.

Noise pollution is usually caused by human sources including transportation vehicles (e.g., cars, planes), construction sites, manufacturing facilities, industrial equipment (e.g., compressors) and amplified sound from entertainment venues (e.g., concerts). Natural events such as thunderstorms can also cause short bursts of noise pollution over certain areas.

Noise pollution has been linked to a range of physical health issues including hearing loss, hypertension and increased stress levels due to disruption of sleep patterns caused by loud noises during nighttime hours. It has also been linked with mental health issues such as anxiety disorder due to fear stimulated by loud noises and annoyance resulting from recurring sounds.

Some common causes behind water contamination include untreated sewage discharge; agricultural runoff containing fertilizers or manure; industrial waste discharge containing hazardous materials such as heavy metals or petroleum compounds; illegal dumping of hazardous materials into bodies of water; leaking underground storage tanks containing oil or gasoline; natural occurrences like volcanoes releasing toxins into rivers.

Contaminated drinking water may contain dangerous microorganisms that can lead to diseases like typhoid fever or cholera when ingested through drinking water that isn't properly treated prior consumption. Pollutants present in surface waters can also weaken shellfish populations if improperly managed which might further lead to scarcity along fisheries - both affecting people's livelihoods.
