he first day of the Cop26 climate talks in Glasgow got off to a rocky start as delegates queued in windy conditions and a fishing row with France threatened to overshadow the summit.
Here are some of the takeaways from day one.
Boris Johnson was keen to stress that time was ticking to tackle the climate emergency as he opened Cop26, and the irony will not have been lost on those waiting for him to deliver his speech, which started half an hour late.
Due to start at midday, the Prime Minister did not start his remarks until 12.30pm, with suggestions it was because US President Joe Biden – having landed at Edinburgh Airport in Air Force One at around 11am – had not reached his seat on time.
Once he did deliver his stark warning, Mr Johnson said: “It’s one minute to midnight and we need to act now.”
Mr Johnson was not the only one running late, as those in the vast queues to just get into the summit itself were also watching the clock.
Reports suggested it was taking those attending the conference hours to get through security checks at points on Monday morning.
Photos of the long lines appeared on social media, with journalists reporting they were being told by security not to tweet pictures and videos of the crowds.
– Just a bit further down the M8
Although maybe not on time, at least Mr Biden was in the right city, unlike veteran US news anchor Wolf Blitzer.
The CNN stalwart was roundly mocked on Twitter for broadcasting from Edinburgh, around 40 miles away, with the city’s famous castle in the background.
He tweeted: “I’m now reporting from Edinburgh in Scotland where 20,000 world leaders and delegates have gathered for the COP26 Climate Summit.”
– A curse on world leaders
Back in Glasgow, the Archbishop of Canterbury was quick to apologise after suggesting in an interview with the BBC that failure to act at Cop26 could be graver than leaders who ignored warnings about the Nazis in the 1930s.
Justin Welby had told the BBC’s political editor Laura Kuenssberg at the Glasgow summit on Monday that world leaders “will be cursed if they don’t get this right”.
But teenage activist Greta Thunberg was not convinced anything would be achieved at the summit.
She criticised the “blah blah blah” of world leaders at the global gathering, which she had “not officially” been invited to despite being one of the most recognisable faces of the youth movement to prevent climate change.
– U-turn for Greenpeace
Also not on the list and therefore not coming in – at least at first – was the Greenpeace vessel the Rainbow Warrior.
The ship was originally forbidden from sailing along the River Clyde, but port authorities changed their mind later in the day and allowed the boat to continue.
Activist Maria Reyes, 19 and from Mexico, was one of those who arrived aboard the famous Greenpeace ship. She warned the summit could not just be a “rich people’s conversation”.
– On his mother’s secret service
Meanwhile, the Prince of Wales was painted as a James Bond-type character who could help fix the climate crisis by the PM.
Earlier, Mr Johnson had likened the plight of the planet to the fictional British spy being strapped to a doomsday device and hurtling towards destruction.
And after listening to a message from the Queen, Mr Johnson is reported to have paid tribute to her son, who earlier delivered a speech to the summit.
The Prime Minister is reported to have said: “We have somebody luckily who drives an electric Aston Martin, as far as I know, and who has a plan that you will have heard earlier on to defuse the ticking time bomb and to get the private sector involved in greening the world, which I think was very very well set out today.”
A video appeared to show US President Joe Biden closing his eyes for around 20 seconds during the opening speeches in Glasgow.
While Mr Johnson was snapped at an unfortunate time with his eyes closed, but a No 10 source told The Mirror it was “total nonsense” to suggest he was asleep and other photos showed him with his eyes open.
That did not stop shadow justice secretary David Lammy taking the opportunity to mock the PM however, as he tweeted: “Time to wake up @borisjohnson the world is burning. Sir David Attenborough is paying attention to the climate crisis, it’s time your Government did too #cop26.”
