Scenarios are the language through which climate models unwrap the future. But, how do we give life to these futures using mathematics and ingenuity? Massimo Tavoni, lead author of the IPCC and director of the RFF-CMCC European Institute on Economics and the Environment, discusses how science designs scenarios, and how these in turn help communicate the climate challenge and guide decisions. — When you think about change you are thinking about the future. As the climate is changing due to human influence resulting from past choices, what we do today has the power to shape many possible futures.

Ski resorts across the Alps are struggling in the face of yet another year with record-low snowfall. But it isn’t just a European phenomenon. All around the globe, researchers are studying how climate change impacts current and future snowfall patterns. And it’s bad news for snow lovers everywhere, with a significant financial burden falling on entire economic sectors. — It has been a hard winter for mountain enthusiasts across the globe, as changing snowfall patterns and environmental factors such as anomalous heatwaves in the European Alps and firestorms in the US have left ski resorts on thin ice.

Is there an order to chaos? Professor Giorgio Parisi walks us through the amazing patterns and rules that govern apparently random phenomena in his Nobel lecture on the theory of complex systems and their implications for our understanding of the world that surrounds us. — On December 8, 2021, Dr. Parisi was given the shared award for his discoveries “about how apparently random phenomena are governed by hidden rules.” His work, which took place in the 1980s, was described by the Nobel prize committee as “among the most important contributions” to the theory of complex…

In his Nobel lecture, Professor Syukuro Manabe explains how man influences the climate and how weather and climate modelling has allowed us to understand this relationship in more detail. Watch the full lecture. — On December 8, 2021, Princeton climatologist Prof. Syukuro Manabe, winner of the 2021 Nobel Prize for “the physical modelling of Earth’s climate, quantifying variability and reliably predicting global warming”, delivered his Nobel Prize lecture, “Physical Modeling of Earth’s Climate.”

The conversation around climate change has never been more intense on social media, where influencers have the power to inspire and even persuade their followers. An international multidisciplinary team has developed a dashboard that allows us to navigate tweets and hashtags providing some answers to this question. So, to what extent are social media users at the mercy of climate change deniers?

Bringing youth to the centre of climate negotiations and ensuring meaningful participation was a key concern for the joint UK-Italy Presidency of the COP26. So, how did ideas developed in Milan by 400 young climate leaders reach the negotiating tables and what elements of the Youth4Climate Manifesto made it into the Glasgow Climate Pact? In the build-up to COP26 in Glasgow around 400 young climate leaders from all over the world met at the Youth4Climate: Driving Ambition summit in Milan to exchange ideas and join in dialogue with experts and high-level speakers, including over 50 Ministers, experts and decision-makers from around the world.

A look at Article 6, one of the thorniest issues in climate negotiations, which has gradually taken shape from Paris to Glasgow and regulates how countries cooperate — from bilateral trade to carbon markets — to enhance mitigation outcomes and support adaptation.

With a draft agreement reached on November 10, and China and the US releasing a joint declaration a few hours later, policymakers, experts and observers start to get a glimpse of what the likely outcomes of the COP26 will be. — Cop26 president Alok Sharma told reporters on Tuesday following the release of the COP26 Draft Agreement: “We are making progress at Cop26 but we still have a mountain to climb over the next few days.”

The IPCC’s press release detailing all essential information on the Working Group I report, the first instalment of the IPCC’s Sixth Assessment Report (AR6), which will be completed in 2022. — Scientists are observing changes in the Earth’s climate in every region and across the whole climate system, according to the latest Intergovernmental Panel on Climate Change (IPCC) Report, released today. …
