a long-term change in the earth’s climate, especially a change due to an increase in the average atmospheric temperature
an increase in the earth’s average atmospheric temperature that causes corresponding changes in climate and that may result from the greenhouse effect.
The pattern of weather conditions within a region over a long period of time,
The condition of the atmosphere at a specific place and time
A theory where the structure of the earth’s crust is split into plates explaining phenomena like Earthquakes.
the theory that states that continents moved slowly over geological time from Pangaea (single continent) to their current continent positions
a geological interval of warmer global average temperature lasting thousands of years that separates consecutive glacial periods within an ice age
Air bubbles from glaciers in order to see contents of air at certain time
Clues used to determine past climates
the gases that surround earth
Temperature Humidity Precipitation Wind Storms
Layers of atmosphere in order and heat pattern
Troposphere, Stratosphere, Mesosphere, Thermosphere –> down –> up –> down –> up (pressure decreases with altitude)
transfer of thermal energy between neighboring molecules
transfer of thermal energy by movements of layers within fluids
transfer of electromagnetic energy by waves travelling through a medium or empty space.
the proportion of the sun’s radiation that is reflected by Earth back to the sun (long wave radiation)
Natural Greenhouse Effect
Radiation from the sun passes through the Earth’s atmosphere and is absorbed by the Earth’s surface. Becomes thermal energy and the Earth Warms-up Earth emits lower-energy infrared radiation Gases in the atmosphere trap radiation GHGs in atmosphere absorb radiation and some is sent back to Earth surface.
electromagnetic radiation with wavelengths longer than visible light
lectromagnetic radiation with a wavelength shorter than that of visible light
the thermal motion of charged particles in matter radiated electromagnetically
Water vapor, Carbon Dioxide, Methane, Ozone, Nitrious Oxides
a gas that contributes to the greenhouse effect by absorbing infrared radiation
Anthropogenic Greenhouse Effect
The natural greenhouse effect however magnified by the greenhouse gas emissions of humans
Positive Feedback Loop
A closed loop system, that enhances positive loop gain over time.
Net Radiation budget
Solar Energy budget: +70% absorbed, 30 % reflected before earth, -70% radiated back
a natural fuel such as coal or gas, formed in the geological past from the remains of living organisms.
any activity that emits Carbon Dioxide
a forest, ocean, or other natural environment viewed in terms of its ability to absorb carbon dioxide from the atmosphere.
the difference of radiant energy received by the earth and energy radiated back to space
A process that acts to amplify or reduce direct warming or cooling effects.
an energy imbalance imposed on the climate system either externally or by human activities.
Keep your lifestyle however, you pay a company to offset your carbon usage by doing things (though there is no way to track this)
Emissions Trading (cap & trade)
When a cap of emissions is set in place on countries or organisations, and if one goes under their limit and one goes over they can trade “emissions”
a tax on fossil fuels, especially those used by motor vehicles, intended to reduce the emission of carbon dioxide.
the deliberate large-scale manipulation of an environmental process that affects the earth’s climate, in an attempt to counteract the effects of global warming.
Carbon capture (sequestration)
Taking the carbon emissions and capturing it, turning it into a liquid/solid and pumping it back into the ground where it came from (coal mines etc.) “a natural or artificial process by which carbon dioxide is removed from the atmosphere and held in solid or liquid form.”
