How do scientists learn about past global temperatures and climates?

Clues about the past climate are buried in sediments at the bottom of the oceans, locked away in coral reefs, frozen in glaciers and ice caps, and preserved in the rings of trees. Each of these natural recorders provides scientists with information about temperature, precipitation, and more.

How does science help us understand why the weather changes?

As surface and water temperatures rise, human, animal and plant life respond. Scientific studies document these responses. In doing so, science builds a foundation for understanding how our lives are impacted by climate change and what we can do to slow or reverse changes.

How the weather is changing?

Daily changes in the weather are due to winds and storms. Seasonal changes are due to the Earth revolving around the sun. What causes weather? These differences in temperature create a restless movement of air and water in great swirling currents to distribute heat energy from the Sun across the planet.

Is the science of climate?

Climate science investigates the structure and dynamics of earth’s climate system. It seeks to understand how global, regional and local climates are maintained as well as the processes by which they change over time.

How do scientists define climate?

In short, climate is the description of the long-term pattern of weather in a particular area. Some scientists define climate as the average weather for a particular region and time period, usually taken over 30-years. It’s really an average pattern of weather for a particular region.

What is the science behind climate change?

These changes are caused by extra heat in the climate system due to the addition of greenhouse gases to the atmosphere. The additional greenhouse gases are primarily input by human activities such as the burning of fossil fuels (coal, oil, and natural gas), agriculture, and land clearing.
