World leaders, politicians, negotiators, business leaders and activists gather in Glasgow for the two-week UN climate summit Cop26.
They discuss how they can best contribute to combating the climate crisis after the 2015 Paris Agreement.
The Cop26 summit aims to urge countries to continue their net zero commitments through the middle of the century and reduce emissions quickly for the next decade through commitments to phase out coal, switch to electric cars, and plant trees to reduce.
Developed countries are also urged to increase the funding – $ 100 billion (£ 73 billion) a year – that poorer countries need to tackle climate change.
Downing Street said Cop26 will be one of the largest events Britain has ever hosted, with 25,000 delegates expected from 196 countries and the European Union.
The international climate conference officially begins on Sunday, the summit of the heads of state and government begins on Monday.
Here are some of the highlights of the action.
Sunday, October 31st: The UN-Cop26 meeting officially begins and initiates the two-week negotiations, which aim to advance measures against climate change and to implement the comprehensive world climate treaty, the Paris Agreement.
Monday, November 1st: The two-day world summit of heads of state and government begins, in which around 120 heads of state and government will take part.
Prime Minister Boris Johnson will host an opening ceremony that will be attended by dignitaries such as the Prince of Wales, and both will speak to leaders.
World leaders will then set out their actions in national statements, with US President Joe Biden, German Chancellor Angela Merkel, Canadians Justin Trudeau and Scott Morrison from Australia speaking on Monday afternoon.
Other leaders, including Japan’s Prime Minister Fumio Kishida and Irish Taoiseach Micheal Martin, will speak on Tuesday.
Members of the Royal Family will attend a number of events and on Monday evening the Prince of Wales, Duchess of Cornwall and the Duke and Duchess of Cambridge will attend an evening reception with world leaders.
The Queen was supposed to host the reception but will now provide a video message for it after she should not travel to Glasgow for health reasons.
Tuesday, November 2nd: In addition to speeches by the Heads of State and Government, there will be events with Mr Johnson and other Heads of State and Government on protecting forests and using land more sustainably, as well as on green energy and infrastructure.
Wednesday 3rd November Chancellor Rishi Sunak will open the conference’s “Finance Day” with an event that will showcase progress in meeting the $ 100 billion climate finance commitment, mobilizing private funding, and “recruiting” the financial sector to support action.
Thursday 4th November The energy day in the talks will focus on phasing out coal and switching to green energy.
Friday 5th November: Friday is Youth Day at Cop26 as young people take part in the Climate School Strike on the streets and march through Glasgow.
Saturday, November 6th: Activists are taking to the streets again with marches in Glasgow, London and other UK cities.
Meanwhile, it’s Nature Day at Cop26, so activists and companies will focus on how protecting nature can promote wildlife and avert the climate crisis.
Monday, November 8th: Environment, energy and climate ministers will take part in the talks for the high-level ministerial part of the negotiations in the second week of the conference.
In the second week, theme days with different focuses on gender, science and innovation, transport and cities will be continued.
Friday, November 12th: The talks are to be ended.
But with difficult negotiations on a range of issues and efforts to get countries to agree on a roadmap for more ambition to reduce emissions over the next decade, it is likely to be overdone.
Climate talks always go.
