Reactions to the climate deal agreed at the COP26 conference in Scotland last night.

Former President of Ireland Mary Robinson

"COP26 has made some progress, but nowhere near enough to avoid climate disaster. While millions around the world are already in crisis, not enough leaders were in crisis mode. People will see this as a historically shameful dereliction of duty.

"Leaders have extended by a year this window of opportunity to avert the worst of the climate crisis. The world urgently needs them to step up more decisively next year."

UN Secretary-General Antonio Guterres

"The approved texts are a compromise. They reflect the interests, the conditions, the contradictions and the state of political will in the world today. They take important steps, but unfortunately the collective political will was not enough to overcome some deep contradictions."

COP26 President Alok Sharma

"I think today we can say with credibility that we've kept 1.5 (degrees Celsius) within reach. But its pulse is weak, and we will only survive if we keep our promises. (...) History has been made here in Glasgow."

Climate activist Greta Thunberg

"The #COP26 is over," she tweeted. "Here's a brief summary: Blah, blah, blah.

"But the real work continues outside these halls. And we will never give up, ever."

Green Party leader Eamon Ryan

"Agreement has been reached at #COP26 in Glasgow. It gives us a chance of keeping 1.5 degrees alive. The last minute deal on coal was deeply disappointing but we had to agree a deal. We can no longer delay. It brings momentum at home & has to deliver climate justice for the world."

British Prime Minister Boris Johnson

"We asked nations to come together for our planet at COP26, and they have answered that call. I hope that we will look back on COP26 in Glasgow as the beginning of the end of climate change, and I will continue to work tirelessly towards that goal."

Greenpeace International Executive Director Jennifer Morgan

"They changed a word but they can't change the signal coming out of this COP, that the era of coal is ending. If you're a coal company executive this COP saw a bad outcome."

WWF Global Lead on Climate Manuel Pulgar-Vidal

"We must acknowledge that progress was made. There are now new opportunities for countries to deliver on what they know must be done to avoid a climate catastrophe. But unless they sharply pivot to implementation and show substantial results, they will continue to have their credibility challenged."

Marshall Islands Climate Envoy Tina Stege

"This package is not perfect. The coal change and a weak outcome on loss and damage are blows. But it is real progress and elements of the Glasgow Package are a lifeline for my country. We must not discount the crucial wins covered in this package"

Costa Rice Environment and Energy Minister Andrea Meza

"Of course, we wanted to see more in loss and damage. Of course, we wanted to see more in the adaptation finance package, but I think that it was a shift in certain ways. I think that for the first time, at least in some rooms, we have space to really have more frank conversations."
