The temperature of earth has been relatively constant over time. This is possible because as the planet absorbs solar radiation, it also emits long-wave radiation into space. Despite this radiative equilibrium, some long-wave radiation remains trappe...d beneath the atmosphere of the earth and warms the surface of the earth. This phenomenon is called the "greenhouse effect." (03:29)

Shortwave radiation emitted by the sun and long-wave radiation emitted by carbon dioxide and water vapor contribute to the heating of the Earth's surface. Over the past 120 years, scientists have observed that the Earth's average global surface tempe...rature has increased. At the same time, the atmospheric concentration of carbon dioxide has also increased. Take a closer look at how these changes may have occurred. (02:22)

People who live north of the equator are experiencing both higher summer temperatures and a greater frequency of extreme bouts of heat, according to a NASA statistical analysis of decades of Northern Hemisphere temperature data. A basic bell curve sh...ows breakdown of these temperatures. Initially, the mean summer temperature for the Northern Hemisphere from 1951-1980 is centered at the top of the curve, with the frequency of cooler summers in blue and the frequency of warmer summers in red. Watch how the frequency of hotter temperatures increases as the visualization moves forward in time, showing how hotter summer temperatures are the new normal.

In this short National Geographic video, students will be able to witnesses changes in nature. Students will be able to define the differences between climate and weather. Climate refers to the average weather conditions of a place over a long time. ...There are 6 main climate zones from mild and inviting to harsh. Weather refers to the day to day conditions of the Earth's atmosphere at a particular place and time. This is a wonderful companion teaching resource for a lesson/unit on climate weather or in conjunction with Common Core Curriculum Unit- Grade 1, Unit 4. (03:22)

Discusses what makes up geography; land, water, people and their lives and how land and water affect them. Geography also includes climate. Climate is the weather pattern in a region of the world over a long period of time. One of the major factors a...ffecting our climate is the Sun. The way the Earth moves around the Sun affects the climate. This video discusses rotation, revolution, year, axis, hemisphere, latitude, lines of latitude, and equator. This video discusses what causes the different climates. This video shows the vocabulary using a picture of the Earth. This is a very good video to show students when discussing climate. (09:03)
