A nationwide consortium, the Institute for Public Accuracy (IPA) represents an unprecedented effort to bring other voices to the mass-media table often dominated by a few major think tanks. IPA works to broaden public discourse in mainstream media, while building communication with alternative media outlets and grassroots activists.
Almost a decade ago, parties to the Paris treaty agreed to work toward limiting temperature rise this century to 1.5ºC—but 2024 was the hottest year in human history, and countries around the world show no signs of reining in planet-wrecking fossil fuels anywhere near the degree that scientists warn is necessary to prevent catastrophic climate breakdown.
"Crossing 1.5ºC for a whole calendar year is a wake-up call for the world," said Olympic gold medalist and XR U.K. spokesperson Etienne Stott, highlighting another alarming record from last year. "If we want to avoid crossing further tipping points we need a complete transformation of society."

Scientists from universities in the United Kingdom and Germany warned in a peer-reviewed paper published in the journal Earth System Dynamics last month that humankind is at risk of triggering various climate tipping points absent urgent action to dramatically reduce emissions from fossil fuels.
"There are levers policymakers can pull to rapidly phase out fossil fuels, but this requires standing up to powerful interests," Stott said Saturday. "Activists need to build power, resilience, and the world we want to see in our communities; but we also need to keep seeking the spark that will cause the worldwide transformation we need to see."
In addition to the Cambridge and U.K. arms of Extinction Rebellion, Saturday's action was organized by Cambridge Greenpeace, Cambridge Stop the War, and the Organization of Radical Cambridge Activists (ORCA).
Varsity, the independent student newspaper at the University of Cambridge, reported that the marchers "rallied at Christ's Pieces, where they heard from one of the organizers, who emphasised the harm caused by exceeding 1.5ºC of warming."
"The march then proceeded up Christ's Lane and down Sidney Street, led by a group of 'Red Rebels,' dressed in red robes with faces painted white, followed by 'pall bearers' carrying coffins painted black, with the words 'Inaction Is Death' in white," according to Varsity. "The procession was completed by a samba band who drummed as they walked, followed by protesters carrying a large sign reading 'Don't silence the science,' along with many other smaller placards."

Photos from organizers show participants displaying banners with messages such as "No Future on a Dead Planet," and additional messages painted on the black coffins: "1.5ºC Is Dead," "Act Now," "Ecocide," "RIP Earth," and "Web of Life."
"Politicians have broken their promises to keep global temperature rises to a livable 1.5ºC," declared Zoe Flint, a spokesperson for XR Cambridge. "For decades, people around the world have been resisting environmental devastation in their own communities and beyond—often facing state repression and violence as a result."
"With dozens of political protesters now in prison in this country, that repression has come to the U.K. too," Flint noted. "But when those least responsible for climate breakdown suffer the worst effects, we can't afford to give up the fight."
Parties to the Paris agreement are set to gather next in November at the United Nations climate summit, COP30, in Belém, Brazil.
