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?

The Breaking News page 40 has been brought up-to-date as of 14th January 2011.

Apologies to all our readers! The site is somewhat out-of-date, but will be updated in the next two weeks, starting today, 28th July 2011. There is a new Breaking News page (54) and a new CO2 last month page and other changes will follow.

There has been a recent attack on the terrestrial temperature records, with claims that only the satellite records are to be believed. Additionally, there is a claim that there has been no warming since 1979 when the satellite record began. These claims are countered in a new page 56. This page was updated 21st October 2011.

BUT see page 54 for the latest on global temperature change! AND an attack on Lord Lawson's Global Warming Climate Foundation. Is he as balanced as he and Benny claim to be?

A description of the performance of the Japanese CGM is on page 57.
