There are many and varied sources of information and discussion about climate change, some are highly technical and some are over-simplified. We have two main aims. One is the explanation of the greenhouse effect on as simple a level as is possible without being scientifically inaccurate. The second one includes advanced explanations with our 'translations' for general readers. Links to our own publications and to other signally important papers in the scientific literature for the more technically minded will be added.

The major questions that arise in the study of climate change are:

1. Are humans responsible for the increase in carbon dioxide [CO₂] in our atmosphere that has occurred since the beginning of the Industrial Revolution?

2. Is this extra CO₂ causing the world to warm up, and if so by how much?

3. Are other greenhouse gases such as methane [CH₄] and nitrous oxide [dinitrogen monoxide, N₂O] important contributors to climate change

4. What other mechanisms could possibly cause climate change?

We hope also to have a section where you may leave questions which we shall attempt to answer or to lead you to the answers by more qualified persons.

APOLOGY

We apologise for the fault that has caused the menu to obscure some of the diagrams. The menu has now been shifted to the left side of each page and the diagrams should now be fully visible. Any that aren't will be altered soon.
