of fossil fuels would cause global temperatures to rise by trapping excess heat in the earth’s atmosphere. a. Arrhenius (1896) understood that the earth’s climate is heated by a process known as the Greenhouse effect b. small concentrations of greenhouse gases like water vapour and carbon dioxide convert some of this energy to heat and either absorb it or reflect it back to the earth’s surface. c. Sunlight passes through, but a certain amount of radiated heat remains

warming is the gradual increase of the temperature of earth's atmosphere and oceans. Over the past century the average temperatures have gone up by just over one degree. This may not seem like much, but many scientists agree that the earth's temperatures are starting to increase at a faster rate. What causes it? Global warming occurs when greenhouse gases, such as carbon dioxide, nitrous oxide, and methane trap heat inside the earth's atmosphere. Think about what happens when you open your car door

wavelength band(s) of the electromagnetic spectrum do they absorb radiation? In your answer, give three examples of greenhouse gases and their wavelengths of absorption. Greenhouse gases are gases in the atmosphere that allow light through but block infrared radiation that is reflected off of Earth’s surface, not allowing the heat to escape and thus causing long term heating effects on our climate. The greenhouse gases absorb some incoming light but the greenhouse effect is cause by the absorption

“Human activities contribute to climate change by causing changes in Earth’s atmosphere in the amounts of greenhouse gases, aerosols (small particles), and cloudiness. The largest known contribution comes from the burning of fossil fuels, which releases carbon dioxide gas to the atmosphere. Greenhouse gases and aerosols affect climate by altering incoming solar radiation and outgoing infrared (thermal) radiation that are part of Earth’s energy balance. Changing the atmospheric abundance or properties

Atmosphere The atmosphere of Earth is a layer of gases surrounding the planet Earth that is retained by Earth's gravity. The atmosphere protects life on Earth by absorbing ultraviolet solar radiation, warming the surface through heat retention (greenhouse effect), and reducing temperature extremes between day and night. Dry air contains roughly (by volume) 78% nitrogen, 21% oxygen, 0.93% argon, 0.038% carbon dioxide, and small amounts of other gases. Air also contains a variable amount of water

metals and agriculture. Lithosphere There are four layers of the atmosphere Thermosphere- Where satellites orbit the earth. Mesosphere- This is where most of the meteorites and comets burn up. Stratosphere- Is where the ozone layer is confined. Troposphere- This is where all animals live; and contains all the earth’s natural air gases, such as Nitrogen, Oxygen and other minor gases. There are four layers of the atmosphere Thermosphere- Where satellites orbit the earth.

Name____________________________ 1) Why is it that weather and climate can be confused at times? 2) What is needed to distinguish between the two? What makes it so difficult to come up with one value of the earth’s surface? Is a 1 degree warming over the earth’s surface is a valid concern? 3) What did the monks from 500 years ago discover? Why were they a good measuring tool? 4) The weather patterns seemed to be highly variable over the last 20 years. Droughts

controlling Earth’s climate resided primarily in the writings of science fiction authors such as Frank Herbert, Isaac Asimov, and Arthur C. Clarke. Today, planetary engineering is being discussed openly by scientists and policymakers in Congress, the UK House of Commons, and many other settings. Clarke’s advice apparently struck a chord: “Politicians should read science fiction, not westerns and detective stories.” Geoengineering can be thought of as intentionally manipulating Earth’s climate to

the Mauna Loa Observatory, located in Hawaii, is to measure the levels of carbon dioxide in order to determine how much of our atmosphere is comprised of this gas. A long feared benchmark among scientist has been reaching 400 parts per million as it is considered a tipping point from which our planet would be unlikely to recover from for centuries. The Earth’s atmosphere reached 400 parts per million almost 5 years ago in 2013. I specifically remember reading about this when it was confirmed and
