Here are some of the best images and key moments from the crucial climate summit so far.

Ahead of the conference First Minister Nicola Sturgeon met indigenous delegates at a ceremonial gathering at the Tramway in Glasgow.

One of the main aims of the conference is to limit a rise in future global warming to a ceiling of 1.5C.

As delegates gathered, campaigners arrived. Greenpeace's flagship Rainbow Warrior sailed up the Clyde, here passing under the Erskine Bridge.

Climate activist Greta Thunberg arrived by train and joined protesters at Festival Park near the Clyde to send her message of "no more blah, blah, blah".

While on the streets the message was put across in a more Scottish accent.

The slogans were being driven home as Scotland was enjoying a more traditional guising, in the wake of the lockdown restrictions of the Covid pandemic.

Back on the conference trail, and US President Joe Biden's journey to Glasgow drew a lot of attention on the M8 as his motorcade travelled from his accommodation in Edinburgh.

Meanwhile, much was made about the non-attendance of Russian President Vladimir Putin and Chinese President Xi Jinping.

The Queen addressed world leaders and other senior royals at a reception at Glagsow's Kelvingrove Art Gallery and Museum, with a message to "rise above politics and achieve true statesmanship.

At the conference venue and around the city security has been extremely tight, with thousands of officers drafted in from around the UK.

Inside, all eyes have been on world leaders, to see what agenda can be agreed as deals are set out on emissions, investment and global climate targets.

European Commission President Ursula von der Leyen outlined one such pledge along with the United States to slash emissions of the powerful greenhouse gas methane.

Keeping up the pressure are groups like Extinction Rebellion, who have also been targeting green investment and financial insitistutions.

As talks continued, there was some disappointment as Indian Prime Minister Narendra Modi only committed to a net zero target for his country by the year 2070.

Activists outside the summit drove home their message that COP26 needed to be a time for action and not "climate games".

Someone else to get her message across was Earthshot Prize finalist Vinisha Umashankar, a schoolgirl from India who has created a solar-powered ironing cart. She took the opportunity to tell world leaders her generation "will live to see the consequences" of their actions at COP26.

Delegates representing indigenous peoples around the world and the global south have been working to make their voices heard among the speeches of world leaders.

And one campaign group seeking to amplify those voices had their inflatable "debt monster" - in the shape of Nessie - seized by police as they sought to launch it on the River Clyde.

More voices were raised by the Glasgow Youth Choir at St Lukes Church in the city, bringing their message to the conference.

Adding a bit of celebrity glitz was Leonardo DiCaprio, who attended the conference and also met Prince Charles and Stella McCartney at a fashion installation by the designer, at the Kelvingrove.

The world leaders summit has finished but the work of the negotiators from countries around the globe will continue as COP26 runs its course.

Security around the event remains as tight as ever, with talks continuing through until 12 November.

And the work of campaigners and protesters is also continuing on the streets and at venues surrounding the conference.

Youth climate activist Kato Ewekia Taomia, from Tuvalu, addressed delegates in the hall. Tuvalu is one of the nations particularly under threat from rising sea levels.

The seas are also the focus for Ocean Rebellion, who have been drawing attention to the climate's impact on the world's marine life.

Tongan activist Uili Lousi stands alongside "Flare Oceania 2021", created by artist John Gerrard, a real-time moving image showing a simulation of the seas around Tonga with the flag/flare embedded in it.

As the weekend approaches, larger mass protests are being held, with the Fridays For Future Scotland Climate Strike on Friday and the Global Day for Climate Justice march on Saturday.

Placards were in full effect on the Climate Strike march, which took place through the centre of the city.

The young activists march gathered in Kelvingrove Park in the west of the city.

Thousands took to the streets to call for world leaders to take more urgent action on the climate.
