Barack Obama urges young people to 'stay angry' in fight against climate change
The BBC reported, Barack Obama has called on young people to "stay angry" in the fight against climate change at the COP26 summit.
It mentioned that the former US president urged them to apply political pressure to make a change, but warned they would need to accept compromises along the way.
Mr Obama said the world is "nowhere near where we need to be" to avoid a future climate catastrophe.
He criticised Donald Trump's "active hostility toward climate science", but said the US is ready to lead again.
Mr Obama also scolded China and Russia's leaders for not physically attending the COP26 summit.
He called out nations for failing to meet the pledges they made in the 2015 Paris Agreement, when he was in the White House.
However, activists were quick to point out those broken by his own administration, including the failure of a key promise by developed countries to deliver $100bn (£73bn) a year in climate finance to poorer nations.

Mr Obama dedicated much of his speech to young activists, who he said were "right to be frustrated".
Addressing young people directly, he said they "can't ignore politics" and that while protesting and hashtags raise awareness, they should get involved in politics at some level.
"You don't have to be happy about it, but you can't ignore it. You can't be too pure for
Referencing his own daughters' shopping habits, he also called on young people to support businesses that were committed to sustainability, and boycott those that were not.
Obama's catchphrase of the night was telling young activists to "stay angry".
He said: "To all the young people out there - I want you to stay angry. I want you to stay frustrated."
"But channel that anger. Harness that frustration. Keep pushing harder and harder for more and more. Because that's what's required to meet that challenge. Gird yourself for a marathon, not a sprint."

He honoured the dedication of activists such as Greta Thunberg who are "forming movements across borders", and urged young people to at least get out and vote for politicians who will stand against climate change.
He said: "Vote like your life depends on it, because it does."
The former president insisted that despite political divisions in the US and the country's absence from global climate efforts for four years during the Trump administration, America was now back on track and committed to change.
Mr Obama made a number of comments about his predecessor, Republican Donald Trump, who once called climate change "an expensive hoax" and controversially pulled out of the Paris climate accord when he took office. The US rejoined it under Joe Biden.
Mr Obama reserved some of his strongest criticism for the Republican Party. He accused its members of stalling progress by "sitting on the sidelines" and making climate change a partisan issue with "four years of active hostility toward climate science".
He said Republicans who take climate change seriously are "a rare breed right now." This is the first year a delegation of Republicans has attended a UN climate summit.
Mr Obama also blamed the pandemic, rise of US nationalism and a lack of cooperation from the Trump administration for a breakdown in international relations that has affected the climate crisis.

Taking a swipe at Russia and China, Mr Obama also said it was "particularly discouraging" that the leaders of "two of world's largest emitters" had not attended the climate summit in person.
While more than 120 leaders turned up at the conference, Vladimir Putin and Xi Jinping, who have both avoided international travel since the start of the pandemic, opted to take part remotely instead.
Mr Obama said they were showing a "dangerous lack of urgency".
The 44th US president closed by telling the crowd that fighting climate change will be hard and messy with "every victory incomplete".
"The thing we have going for us is that humanity has done hard things before," he said, adding: "I believe we can do hard things again."
