We are days away from a pivotal moment in the fight against climate change.
COP26, the 26th Conference of the Parties to the United Nations Framework Convention on Climate Change, takes place in Glasgow from 31 October to 12 November.
Amid concerns that the summit might fail to achieve the commitments needed to constrain global warming, we asked several young people to send a message to the world leaders who will gather in Scotland for 12 days of talks.
Today, we hear from Theresa Rose Sebastian, a Leaving Certificate student in Mount Mercy College in Cork, who will be attending COP26.
"I will be there to ensure our world leaders know exactly what we think and what justice means," she said. "As a global nation, we are one. When one of us hurts, all of us need to stand in solidarity."
Theresa's journey to becoming a climate activist started three years ago, when at the age of 14, she was faced with extreme flooding in India.
"I’d gone home to Kerala where I'm from in India, we were there for my cousin’s wedding and it started to rain," she recalled.
"We're used to rain - it was the monsoon period - but this was a lot worse. The rain never stopped. It increased and got worse and worse to the point we couldn't see outside. Tree trunks were submerged, the carpark was completely under water and cars were floating.
"I was 14, I was young and quite naïve to how the world worked, and I thought it was as if the world was ending."
The flooding was an eye-opening, frightening experience. But when Theresa returned to Ireland, she became frustrated that the disaster wasn't being covered in the media.
"No national or global media were discussing the atrocity. We lost 400 lives and had hundreds of camps set up for displaced people, but what global media organisations were covering at that time was Donald Trump's golf trips," she said.
"For me, that was really frustrating. We lost lives as a nation, but it was his golf trips that were given more attention. So from there I took the initiative to learn what climate change is, what exactly is happening and how is it happening."
Theresa plans to study Law and Social Justice at University College Dublin next year. She sees it as the next step in her fight for climate justice for all.
"We have to live in, and construct a world that's built on justice, sustainability and empathy, where each and every one of us is fair to each other and we’re all equal," Theresa explained.
"The one we're in now, the global south nations are suffering at the hands of what the global north have produced. It's always the ones that have nothing to do with the crisis, that are the most impacted. But that isn't to say that the global north will be left alone.
"The climate crisis does not have borders, we are one global community but the way we're impacted is different, but the reality is that we will all be impacted by the end of it."
Theresa is calling for "huge systematic change" and "the deconstruction of the fossil fuel industry". The latter, she said, must be done in a way that looks after the people working in that industry.
She added: "We can't forget the people who work in these industries who have no other means of a livelihood without it; we need to ensure there is a just transition to a more sustainable, equitable and just-oriented future and system that has everyone in mind and has people over profit."
Theresa is looking forward to bringing her message to world leaders at COP26, a conference she said, she "has both hopes and fears for."
"One thing I want to say to world leaders is: stop patting your backs and put your backs into it. We've had enough of these adaptation tactics when you continue to aggravate the crisis," she said.
"There has never been a shortage of solutions and there has never been a lack of research, all there has been a lack of is justice.
"This COP is so crucial because it quite literally defines who survives and who doesn’t ... The way we're going, we have very little chance of reaching a sustainable world, but it isn't to say we don't have time, we do, but for the little time we have left, we are not doing enough."
