Patterns in Systems Answers

The use of coal has steadily increased from 1800 to 2004. Burning coal was the leading cause of global fossil carbon emissions until around 1970, when the petroleum became the leading cause of global fossil carbon emissions. Petroleum use rose quickly after 1950.

Tracking changes in the climate system can help forecast weather conditions. It can also help predict natural disasters, such as hurricanes. Another advantage of tracking changes in the climate system is the ability to determine human impact on the climate system.

The carbon, oxygen, and nitrogen cycles are all biogeochemical cycles. They show the movement of elements through living and nonliving components of the Earth. Carbon, oxygen, and nitrogen, are essential components of life that pass through organisms and nonliving components, but are never used up.

The Radiosonde is used to measure temperatures, humidity, and pressure of the upper atmosphere. It can take measurements at up to 30 km.

More than one instrument is needed to measure change in the climate system because its complexity. The climate system involves the interaction of the atmosphere, land masses, and bodies of water. Because there are a variety of factors that influence climate, a variety of instruments are needed to measure changes in the climate system.

Climate change involves many different factors, such as temperature, precipitation, atmospheric gases, and ocean conditions, across many locations and time scales. Different instruments measure different variables, so a variety of tools is needed to build an accurate and complete picture of change in the climate system.

A radiosonde is an instrument package carried by a weather balloon that measures atmospheric conditions such as temperature, air pressure, and humidity at different altitudes. Its measurements help meteorologists understand and forecast the weather.

The carbon, oxygen, and nitrogen cycles are similar because each recycles an element through living organisms and nonliving parts of Earth, including the atmosphere, water, and soil. Each cycle involves processes that transfer matter between these components.

Tracking changes in the climate system helps scientists identify trends and make better predictions about future conditions. This information can help communities prepare for risks such as heat waves, droughts, floods, and sea-level rise; protect people and ecosystems; and make informed decisions about adapting to change and reducing its impacts.

Coal use rose greatly during the 1800s and was an important energy source into the 20th century. Petroleum use was low at first, but increased rapidly during the 20th century and had surpassed coal by 2004.
