GovPubs | Climate and Weather These resources deal with climate and weather issues. They may track weather over specific periods of time or deal with specific areas of concern, such as global warming. For more information on climate change, check out the related resources.

International Organization Information National Climate Data Center (NCDC) Climate Data Online Includes current and historical climate and weather data by country and by region. Nongovernmental Sources Climate and Weather CD-ROMs These CD-ROMs contain climatological data and are available on the computers in the Government Information library.

NWS JetStream The atmosphere is a cloud of gas and suspended solids extending from the Earth's surface out many thousands of miles, becoming increasingly thinner with distance but always held by the Earth's gravitational pull. The atmosphere is made up of layers. it surrounds the Earth and holds the air we breathe; it protects us from outer space; and holds moisture (clouds), gases, and tiny particles. In short, the atmosphere is the protective bubble we live in. This protective bubble consists of several gases (listed in the table to the right) with the top four making up 99.998% of all gases. Of the dry composition of the atmosphere nitrogen, by far, is the most common. It is also necessary for combustion or burning. Argon is used in light bulbs, in double-pane windows, and to preserve the original Declaration of Independence and the Constitution. These percentages of atmospheric gases are for a completely dry atmosphere. Water vapor contribution climbs to near 3% on extremely hot/humid days.

Human-caused climate change is not scientifically controversial. Although most U.S. adults believe that the climate is changing, only about half know that human activities are substantially responsible. How to Learn about Climate Change The science of climate change encompasses many disciplines and is unfamiliar to many. What are the Challenges Facing Climate Change Education? There are obstacles to climate change education beyond the attempts of climate change deniers to undermine climate change education. Are you a community member, scientist or activist interested in learning about how you can support climate change education in your community?

Climate Change & Food Security NESDIS-National Environmental Satellite, Data, and Information Service Australian Academy of Science Without the greenhouse effect we would be living in a very chilly place – the world's average temperature would be minus 18°C, instead of the 15°C we are used to. So what is the greenhouse effect and how does it make Earth around 33°C warmer? The natural greenhouse effect The natural greenhouse effect is a phenomenon created by gases naturally present in the atmosphere that affect the behaviour of the heat energy radiated by the sun. This process is known as the greenhouse effect because it is similar to how a greenhouse works – the sun's energy passes through the glass (or similar) panes of the greenhouse, but not all of it is allowed to escape again, making the inside of the greenhouse a warmer and more hospitable environment for the plants inside. Image: IPCC 2007 The Earth's energy balance The composition of the atmosphere is changing The Earth's atmosphere is made up of 78% nitrogen and 21% oxygen.
