Thank you to everyone for your comments about the closure of the low graphics service.

I appreciate that the does not offer the same full range of content but that is something we will be working on in the coming months.

I referred to a new suite of tools which we hope to make available in the summer. These should allow you to easily select a simplified version of the News site - much like low graphics - whatever we have on the full web version should also be available there too.

Read on and comment at the Â鶹Éç Internet Blog.

To some, it's a massive conspiracy to con the public. To others, it's the greatest threat to the future of our world.

Over recent years, opinions about global warming have become increasingly polarised.

It came to a head late last year when hundreds of e-mails from the University of East Anglia's were published.

The .

Despite governments, scientists and campaigners telling us the world's climate is changing, opinion polls suggest growing uncertainty about global warming.

It hasn't helped that recent and a mild winter have been spectacularly wrong.

to ask what we really know about our climate and how it affect us.

His examination of the topic comes just ahead of the third and final report into "Climategate".

Thus far, there have been two inquiries: the and an .

Both found that there was no grand global conspiracy and no deliberate scientific impropriety or dishonesty.
has looked at whether the scientists involved could have been more open with their critics.

The e-mails, which talk of hiding and deletion, gave some the impression that information had been deliberately withheld. They also appeared to lift the lid on an apparently vicious and personal conflict.

We wanted to pin down what, if anything, is broadly agreed and certain about global warming.

Top Gear may have its "Cool Wall", but we have built a "Wall of Certainty". We tested it out on some leading scientists and asked them a few key questions about climate change.

We gave them just four options - certain, likely, unlikely or no way. The answers were fascinating.

First up was Professor Bob Watson. He chaired the for five years, worked for , and is now .

Second was the leading sceptic , an atmospheric scientist at the University of Alabama in Huntsville.

Contrary to some of the newspaper headlines and blogs that , they agreed that mankind is causing the planet to warm up.

We also hear from the scientist behind the graph which has become an icon in the climate-change debate. regrets the way his so-called "hockey-stick graph" was put in the spotlight by politicians.

And we find out that the leading sceptic , author of the best-selling book The Skeptical Environmentalist, accepts much of the basic science and agrees with the critical IPCC finding that most of the recent global warming is man-made.

There is genuine uncertainty and disagreement about the exact scale and speed of human-induced global warming and crucially what we should do about it. But I was surprised to find how much agreement there is on the fundamental science.

Close observers of the Â鶹Éç News website's "most popular" box might have noticed a rich crop of unusual - and usually old - stories appearing in the past week or two. Examples include , , and .

In 2006, a certain story about a Sudanese goat resurfaced long after it had first been in the news and my colleague Adam Curtis wrote about how the viral potential of the web makes it hard to predict which stories readers will tell their friends about.

We've seen odd stories resurface from time to time - but lately the increased number of such old stories prompted us to investigate further.

We think we've worked out what's going on. Our front page usually shows you the "most shared" list, while pages for individual news stories show you the "most read". In the process of upgrading some of the software which publishes our site, we started to show you "most shared" on story pages as well as the front.

This means that any odd eye-catching story from the archive has been displayed on many more pages than it would normally have been, with the result that more people than normal have read it, more people than normal have then shared it with their friends, and the higher it has then climbed in the rankings.

We're now putting things back the way they were - though doubtless it won't be long before the Sudanese goat makes another appearance, one way or another.

Links to external sites are an important part of the Â鶹Éç News website and I have blogged previously about how and why we are aiming to develop what we do in this area - here and here.

One theme that came up was what we should do about linking to sites which require subscription. There were mixed views; on balance, you seemed to be in favour of us providing the most relevant links, wherever they are, with some saying they'd like us also to flag links which require subscription if you follow them.

That is broadly the direction we are going in. As the Times moves into online subscription and others consider the options - see, for example, - there is likely to be a changing landscape with some sites and stories behind paywalls, some not, and some which are in between - a certain number of visits or part of an article free, all depending on the user's individual circumstances.

Our approach will continue to be to take editorial justification as our guiding principle - the relevance of the link in relation to the story we are reporting and its usefulness to you in that context. Beyond that, we will, where practical, aim to tell you if the link is going to a subscription site. Our automated Newstracker module, for example, should be able to do this and already signals when registration is required.

For in-line links in blog posts and news stories, it may be impractical to do this for reasons of space, layout or time. Whatever we do, though, we will look for the best and most useful links for you, while following our approach to external links - which you can find at the bottom of every page.
