We will, in the course of our study, learn a few new words. We'll look at available definitions on the internet, and refer to them; if there's none or we think we can define them better, we'll do so. We had our first Greentionary 2 months ago. You could always look them up again: there's the Green Dictionary link on the left margin.
GREENHOUSE GASES are chemical compounds that contribute to the greenhouse effect. When in the atmosphere a greenhouse gas allow sunlight (solar radiation) to enter the atmosphere where it warms the Earth’s surface and is reradiated back into the atmosphere as longer-wave energy (heat). Greenhouse gases absorb this heat and ‘trap’ it in the lower atmosphere. Source: The Encyclopedia of Earth
THE GREENHOUSE EFFECT is a naturally occurring process that aids in heating the Earth's surface and atmosphere. It results from the fact that certain atmospheric gases, such as carbon dioxide, water vapor, and methane, are able to change the energy balance of the planet by absorbing longwave radiation emitted from the Earth's surface. Without the greenhouse effect life on this planet would probably not exist as the average temperature of the Earth would be a chilly -18° Celsius, rather than the present 15° Celsius.

Pinoy Green Academy recommends as a good resource website the Encyclopedia of Earth, our main source in this post.
"The Encyclopedia of Earth is a new electronic reference about the Earth, its natural environments, and their interaction with society. The Encyclopedia is a free, fully searchable collection of articles written by scholars, professionals, educators, and experts who collaborate and review each other's work. The articles are written in non-technical language and will be useful to students, educators, scholars, professionals, as well as to the general public."
