The UN's secretary general has a chilling message on global warming for the political leaders and diplomats gathering in Madrid for two weeks of talks on climate change. "The point of no return is no longer over the horizon," warns António Guterres, adding: "It is essential that we secure more ambitious national commitments - particularly from the main emitters - to immediately start reducing greenhouse gas emissions at a pace consistent to reaching carbon neutrality by 2050."

Fifty world leaders are expected to be among 29,000 attendees at this year's Conference of the Parties (or COP25), which signals the start of a frantic 12 months of negotiations ahead of next year's event in Glasgow, at which new emissions reductions targets are expected to be set in stone. US President Donald Trump will not be among them, although Speaker of the House of Representatives Nancy Pelosi will attend the conference with a congressional delegation. Meanwhile, Save the Children says climate shocks - in the form of flood, landslides, cyclones and droughts - have left 33 million people at emergency levels of food insecurity. "The climate crisis is happening here, and it's killing people, forcing them from their homes and ruining children's chance of a future," says the charity's Ian Vale.

London Bridge terror attack victims Jack Merritt, 25, and Saskia Jones, 23, are to be honoured in a remembrance service at Guildhall Yard in the City at 11:00 GMT. London Mayor Sadiq Khan is expected to attend the vigil, which will also pay tribute to those who were injured, the emergency services and members of the public who responded. Among them were staff at Fishmongers Hall, whose chief executive Commodore Toby Williamson has described their bravery. It comes after Prime Minister Boris Johnson said 74 people released early from jail sentences for terror offences will have their licence conditions reviewed. We also examine some of the claims made about release procedures.

Most papers lead on some aspect of the London Bridge terror attack. Some focus on the victims, with the Sun paying tribute to "angels stolen by pure evil" and the Daily Mirror saying victims Saskia Jones, 23, and Jack Merritt, 25, were "failed by a cash-strapped, broken justice system". Others report the arrest of a man on suspicion of preparation of apparently unrelated terrorist acts, which the Daily Mail says is the first in a "new blitz on freed jihadis". Intelligence officials are "on alert" for copycat attacks, says the Times.
