An introduction to the issue of the greenhouse effect

Industrial emissions of greenhouse gases that affect the climate. Green carbon Carbon stored in terrestrial ecosystems e. Black carbon Formed through incomplete combustion of fuels and may be significantly reduced if clean burning technologies are employed. But a mitigation approach needs to consider all these forms of carbon they note, not just one or two:

An introduction to the issue of the greenhouse effect

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.

An introduction to the issue of the greenhouse effect

Most of this thermal radiation is absorbed by the atmosphere and warms it. The atmosphere also gains heat by sensible and latent heat fluxes from the surface.

The atmosphere radiates energy both upwards and downwards; the part radiated downwards is absorbed by the surface of Earth. This leads to a higher equilibrium temperature than if the atmosphere were absent.

The atmosphere near the surface is largely opaque to thermal radiation with important exceptions for "window" bandsand most heat loss from the surface is by sensible heat and latent heat transport. Radiative energy losses become increasingly important higher in the atmosphere, largely because of the decreasing concentration of water vapor, an important greenhouse gas.

It is more realistic to think of the greenhouse effect as applying to a "surface" in the mid- tropospherewhich is effectively coupled to the surface by a lapse rate.

The simple picture also assumes a steady state, but in the real world, there are variations due to the diurnal cycle as well as the seasonal cycle and weather disturbances.

Solar heating only applies during daytime.

An introduction to the issue of the greenhouse effect

During the night, the atmosphere cools somewhat, but not greatly, because its emissivity is low. Diurnal temperature changes decrease with height in the atmosphere. Within the region where radiative effects are important, the description given by the idealized greenhouse model becomes realistic.

It reradiates in all directions, both upwards and downwards; in equilibrium by definition the same amount as it has absorbed. This results in more warmth below. Increasing the concentration of the gases increases the amount of absorption and reradiation, and thereby further warms the layers and ultimately the surface below.

Greenhouse gases Main article: Greenhouse gas By their percentage contribution to the greenhouse effect on Earth the four major gases are: The absorption patterns of water vapor blue peaks and carbon dioxide pink peaks overlap in some wavelengths.

Carbon dioxide is not as strong a greenhouse gas as water vapor, but it absorbs energy in longer wavelengths 12—15 micrometers that water vapor does not, partially closing the "window" through which heat radiated by the surface would normally escape to space.This simple experiment serves as an introduction to the greenhouse effect.

- INTRODUCTION Greenhouse effect has been a significant issue since the world start to civilize and industrialize. Greenhouse effect occurs due to human activities and many of countries are still finding the best way to solve the problem of greenhouse in this twenty-first century, even though greenhouse effect is a common incident for decreases.

Though you may not have noticed it, the equity issue is moving in the international climate negotiations. In particular, the Climate Action Network — the largest of the international civil-society network working the climate talks — has floated a discussion paper on “equity reference frameworks.”.

WATCH my "CO2 Experiment".This video shows that a candle floating on water, burning in the air inside a glass, converts the oxygen in the air to CO blog-mmorpg.com water rises in the glass because the CO 2, which replaced the oxygen, is quickly dissolved in the blog-mmorpg.com water contains calcium ions Ca ++, because we initially dissolved calcium hydroxide Ca(OH) 2 in the water.

Carbon dioxide (CO 2) is the primary greenhouse gas emitted through human blog-mmorpg.com , CO 2 accounted for about % of all U.S. greenhouse gas emissions from human activities.

Carbon dioxide is naturally present in the atmosphere as part of the Earth's carbon cycle (the natural circulation of carbon among the atmosphere, oceans, soil, plants, and animals).

An introduction to global warming What is global warming? Global warming is when the earth warms up (the temperature increases). The greenhouse effect is when the temperature goes up because the sun's heat and light is trapped in our atmosphere.

This is like when heat is trapped inside car. Global Environmental Issues; Environmental.
