Not green enough
On tonight's programme, a disturbing report about just how much needs to be done to cut carbon emissions if global temperatures are to be kept below danger levels.
More details later, but our Science Editor Susan Watts and our Ethical Man Justin Rowlatt are on the case.
We'll also be asking two politicians if policy makers are doing enough to encourage, or even force, us to live greener lives.
We've got Carter
George Bush has been making the case for military tribunals to try al-Qaeda suspects recently transferred to Guantanamo from CIA prisons abroad. Prisons that he only last week admitted exist at all.
Peter Marshall is in Washington, and has been finding out that opposition to the plans come not just from Democrats, but from the highest levels of the military.
I've talked to former US President Jimmy Carter about the proposals, and he is surprisingly supportive of the President. Although he has deeper concerns about the way religion and politics are increasingly intertwined - the subject of his latest book.
And he has interesting things to say about the special relationship too.

There's been a heated debate on the Newsnight website today about Clare Short's announcement that she is standing down at the next election to campaign for a hung parliament.
Is it really possible to campaign for such a thing? Moreover, is it possible to say this and retain the Labour whip?
The signs tonight are that she may not keep it for long. We'll be discussing Clare Short's latest outburst with two of her fellow MPs.
