Writes “carbonbrief.org”:

The move follows a ruling earlier this year by Ofcom, the UK’s broadcasting regulator, which found that BBC Radio 4’s flagship current-affairs programme Today had breached broadcasting rules by “not sufficiently challenging” Lord Lawson, the former Conservative chancellor.

Here are the essentials of the ruling:

What’s the BBC’s position?

• Man-made climate change exists: If the science proves it we should report it. The BBC accepts that the best science on the issue is the IPCC’s position, set out above.
• Be aware of ‘false balance’: As climate change is accepted as happening, you do not need a ‘denier’ to balance the debate. Although there are those who disagree with the IPCC’s position, very few of them now go so far as to deny that climate change is happening. To achieve impartiality, you do not need to include outright deniers of climate change in BBC coverage, in the same way you would not have someone denying that Manchester United won 2-0 last Saturday. The referee has spoken. However, the BBC does not exclude any shade of opinion from its output, and with appropriate challenge from a knowledgeable interviewer, there may be occasions to hear from a denier.
• There are occasions where contrarians and sceptics should be included within climate change and sustainability debates. These may include, for instance, debating the speed and intensity of what will happen in the future, or what policies government should adopt. Again, journalists need to be aware of the guest’s viewpoint and how to challenge it effectively. As with all topics, we must make clear to the audience which organisation the speaker represents, potentially how that group is funded and whether they are speaking with authority from a scientific perspective – in short, making their affiliations and previously expressed opinions clear.
