Greenhouse effects

History of climate change science The existence of the greenhouse effect was argued for by Joseph Fourier in The argument and the evidence were further strengthened by Claude Pouillet in and and reasoned from experimental observations by John Tyndall inwho measured the radiative properties of specific greenhouse gases. Most of the remaining energy is absorbed at the surface of Earth. Most of this thermal radiation is absorbed by the atmosphere and warms it.

Lay the thermometers in direct sunlight. Let Greenhouse effects sit in the sun for three minutes. Open up a page of the notebook and draw two columns, one labeled "Thermometer A" and one labeled "Thermometer B.

Welcome to Global Climate Change and Microwaves

Place one of the thermometers in the jar or container and seal. Make sure the lid doesn't cast a shadow on either thermometer! Record the temperature of the thermometers every minute for ten minutes.

Discuss how the container affected the temperature of thermometers. How did the temperature inside the container change compared to outside the container?

The thermometer outside of the container is constantly being exposed to air that is constantly changing temperature, as the warm air mixes with passing cooler air. The air inside the container is trapped and can't mix with the cooler surrounding air—it just gets warmer as the sunlight heats it up.

A greenhouse works in a similar way; solar energy in the form of light creates thermal energy, or heat, that can't escape through the glass. This activity mirrors how a greenhouse works, but it's not exactly the same as the greenhouse effect that is taking place in the Earth's atmosphere.

A complex interaction between light, heat, and chemicals make up the greenhouse effect and the chemicals known as "greenhouse gases" in the environment.

Greenhouse effects

Some greenhouse gases are actually helpful and natural—they keep the Earth's surface from getting too cold. In fact, without some greenhouse gases, the humans would regularly experience temperatures as low as zero degrees Fahrenheit, or degrees Celsius.

The problem comes when pollution caused by human industrialization creates additional greenhouse gases, such as carbon dioxide. Excess greenhouse gases in the atmosphere increase the overall temperature of the earth and disrupt the natural balance of the Earth.

MAS Distro - Exclusive Worldwide Representation. Greenhouse Gas Concentrations: Natural vs man-made (anthropogenic) 1. The following table was constructed from data published by the U.S. Department of Energy (1) and other sources, summarizing concentrations of the various atmospheric greenhouse gases.

Because some of the concentrations are very small the numbers are stated in parts per billion. The greenhouse effect occurs when Earth's atmosphere traps solar radiation because of the presence of certain gases, which causes temperatures to rise.

What would happen to the climate if we stopped emitting greenhouse gases today?

More Greenhouse Gases = A Warmer Earth. Even though only a tiny amount of the gases in Earth’s atmosphere are greenhouse gases, they have a huge effect on climate. The greenhouse effect is the process by which radiation from a planet's atmosphere warms the planet's surface to a temperature above what it would be without its atmosphere..

If a planet's atmosphere contains radiatively active gases (i.e., greenhouse gases) they will radiate energy in all of this radiation is directed towards the surface, warming it. 5 Summary This is a study examining the greenhouse gas emissions, environmental impacts and socio-economic effects of the production of conventional and non-conventional fuels and formulates.
