The purpose of the website is mainly to provide information about the causes and effects of Global Warming. Though little, it also mentions about how we can do to reduce and prevent further temperature rising.

Coverage:
Website targets audiences who are concerned and want to know more about Global Warming. It provides detailed articles as well as graphs which supports and increase the source's reliability. It is definitely comprehensive as it covers a wide area on Global Warming. Though there are links to other useful websites related to my topic, it is rather difficult to locate them.

Authority:
The website is from an authorative source, ScienceDaily, where information are updated daily.

Accuracy:
The latest article posted was on 22 July 2008, which is the day i posted this. It shows the efficiency of the articles and definitely there is quality in its accuracy. Most of the articles are posted after doing studies and analysis from researchers and professionals. In addition, the statistics can help support and increase its accuracy of the discussed area. All the references are stated clearly and there is no grammatical errors whatsoever.

Currency:
The website and its information is updated daily, therefore being up-to-date. The information is well maintained, but the interface is rather difficult to read, as the placing of articles made the website look too wordy.

Accessibility:
The website is easily accessible, and also free from signing up and login in to read the aticles, which makes it more convinenent for users. It is free too. The arrangement as mentioned has much more to be improved, but the links are mostly located as the sides of the page, therefore users can find them easily. There are pictures relating to the articles to help users get a pictorial view of the effects of Global Warming, such as Retreating Ice Glaciers.

Usability:
Nagivation would not be a problem for users, and the pictures relating to the articles can also help link to the articles itself. However, some links are too small to locate, and users may find the website too wordy and squeezy.

Overall:
Overall, I feel that the website is a very good source of information and articles relating to Global Warming. However, the wordy-ness together with user interface of the pages must be improve to attract users attention to read more, or else it would tire our eyes out. If I am to rate the site, it would be 8/10.
