This weekend marks 100 days until the Cop26 climate conference, where world leaders will fly into Glasgow for a series of vital climate talks.

Ahead of the conference, protestors are gathering in Parliament Square on Friday to call on Boris Johnson to make climate a top government priority amid floods and wildfires across the world.

“Cop26 in Glasgow [is] a pivotal moment for the world to come together to meet and master the climate challenge … in little more than 100 days, we can save the next hundred years,” said John Kerry, the special envoy for climate to Joe Biden.

Alok Sharma will act as president of the summit. He said: “Cop26 is our last best hope of avoiding the worst effects of climate change, and we cannot afford to fail. Over the next 100 days, we need all governments to accelerate the green transition, so that we leave Glasgow with a clear plan to limit global warming to 1.5C.

“This will set the course of this decisive decade for our planet and future generations.”

Progress has been made in the past year. A growing number of countries have committed to reaching net-zero emissions by the mid-century. However, there is still more progress that can be made.

John Sauven, the executive director of Greenpeace UK, said: “The US is not pulling its weight – it’s the only country holding up the $100bn pledge. If the US does not put its hands in its pockets and make up the shortfall, Glasgow will be in jeopardy.”
