The greenhouse effect has been ever-present in media for years but how many of us really know what the greenhouse effect actually means?

The sun shines down on the surface of our Earth. The Earth absorbs the rays of lights which are turned into heat reflected back into space, kept back by so-called greenhouse gasses (and clouds). Thus the heat is reflected back on Earth which causes to increase in temperatures within our atmosphere and on Earth.

It is an ongoing discussion to what extent the greenhouse effect is man-made and what can be done about the problem.

Keynote speakers on the greenhouse effect typically look at this discussion and its many questions.
