You published a letter from Paul Shaw on Friday saying that "we have overwhelming evidence that carbon is the cause of global warming". I hope you will allow me to point out that not only do we have no actual evidence (a theory is not evidence) but that we know for a fact that no unprecedented warming is taking place.
It has been known for a long time that the Middle Ages were warmer than now, the late Roman period even warmer & 10,000-5,000BC warmer yet. The closest thing to catastrophe was that in the latter the Sahara was covered in vegetation & animals such as hippopotamuses. It has also been recently proven that the "evidence" that 1998 was the "warmest year in a 1,000" is rubbish - it is actually only the warmest year since 1934.
I wonder if this is the first report in the Scottish press of the evidence that, at least in the US where the best records are, the claim of current unprecedented warming has been disproven.
It will be interesting to see if there is any written response & if it will be anything more than assertion that all "deniers" are lying. It has been interesting to see that whatever the papers say on their online comments (even the Guardian), where they are not edited, the balance of opinion is against the alarmist case.
