John Weyant: Integrated Assessment Modelling informing future climate policy

“Whether or not we keep up with the needs of policymakers will be determined by how much they trust the results from models and how relevant they are to their needs.” Professor John Weyant of Stanford University discusses the evolution of Integrated Assessment Models (IAMs), emphasizing the importance of incorporating growing datasets to meet policymakers’ needs. The Integrated Assessment Modeling Consortium (IAMC) gathers leading climate modeling experts, facilitating crucial advancements in scenario development for climate policy. Its contributions, including defining concepts like Net-Zero, are crucial in informing international climate agreements and shaping future strategies for combating climate change.

Beyond forecasting: Machine Learning exploring climate impacts

Machine learning has emerged as a transformative tool in climate research, evolving from theory to practice over the past few decades. In this context, CMCC is expanding its focus beyond traditional climate modeling to include the study of environmental, social and economic impacts of climate change through data-driven approaches. This transformation is expected to involve all-encompassing capacity building, with substantial infrastructure investments alongside efforts to enhance the knowledge base of scientists.

The AI revolution in weather forecasting: Reactions and comments from the mediasphere

The accuracy and timeliness of weather forecasts can make all the difference in decision making processes. However, as private sector actors leverage artificial intelligence to develop more accurate forecasts than traditional models, experts and journalists try to identify new ethical, political, and technological challenges for the future of weather forecasting.

“We will not go silently to our watery graves”: How to save a nation from drowning

The Marshall Islands, a nation of low-lying atolls threatened by rising sea levels, is facing an existential crisis. Yet, amidst this adversity, the Marshallese people are not only adapting to climate change but also charting a path for survival. Drawing inspiration from their rich maritime heritage, the Marshall Islands have developed a groundbreaking National Adaptation Plan for Survival (NAP). This plan, unveiled at COP28, outlines a comprehensive strategy for addressing the climate crisis over the next century.

Democratizing climate modeling for more pertinent and accurate policy insights

Integrated Assessment Models (IAMs) play a pivotal role in shaping climate research and policy. “The main progress lies in democratizing modeling capabilities across different countries, ensuring more pertinent and accurate policy insights,” says Roberto Schaeffer. The need for a shift towards national-level modeling of climate impacts, the complexity of balancing immediate costs with long-term benefits at the policy level, and the representation gap between countries, are at the core of the current discussion around climate modeling.

COP28 | GIULIO BOCCALETTI. The take-home messages: Advanced knowledge of climate and its interaction with society matters far more.

“CMCC’s strategy aligns with the state of science and society today”. CMCC Scientific Director Giulio Boccaletti comments on the outcome of COP28 in Dubai, where our scientists were engaged in many topics, ranging from adaptation to loss & damage, land use and the science-policy interface. The growing need for integrated scientific knowledge, the intertwining of the climate and socio-economic systems, the ever-closer integration of adaptation and mitigation, and the opportunities arising from machine learning and available data: the points that emerge from COP28 are at the heart of the CMCC strategy.

Climate and health: understanding the entanglement

Infographics, resources, and analyses to understand the way climate change and health are closely connected. The increasing frequency of extreme weather events and substantial environmental transformations, primarily driven by climate change, pose significant threats to both physical and mental well-being. These changes have far-reaching implications for safety, affecting people’s access to critical resources such as clean air, safe water, food, and healthcare.

Blue crabs and other aliens: the era of invasive species

The spread of this Atlantic species threatens biodiversity, as well as the economy and tourism of Mediterranean countries. But, it is not the only unwanted guest: according to a report published by IPBES, alien invasive species cost humans $423 billion each year.

How good is ChatGPT at climate science?

CMCC President Antonio Navarra reflects on our interview with ChatGPT and how good it is at answering questions related to climate science. “ChatGPT doesn’t actually ‘understand’ anything [but] the technology’s potential is enormous and the next versions will be able to do much more than this interview shows.”

Land and climate change: a close connection

Land is a critical resource. It is under pressure from human activities and climate change, but it is also part of the solution. According to the IPCC, keeping global warming below 2°C can be possible only by reducing greenhouse gas emissions from all sectors, including land and food. The way we use land impacts climate change and, in turn, climate change deeply affects our land.
