Climate Change Impacts

COP28 | MASSIMO TAVONI. “Science points to a loss and damage fund of several hundred billion USD”

The loss and damage fund has been established, and initial pledges have been made, but how much money should be directed into it and how should it be organized? Massimo Tavoni, director of the CMCC-RFF European Institute on Economics and the Environment, explains how climate-economic science and modeling can support the loss and damage debate. The latest evidence indicates that an adequate fund should be in the order of [140-822] USD billion and that it should differ from existing funding arrangements used for mitigation and adaptation.

COP28 | MARTA ELLENA: “Three intertwined pillars to solve the climate crisis”

Positioned as a pivotal theme at COP28, adaptation efforts should aim for a shared and common framework to fortify resilience and reduce vulnerabilities at different scales. Adaptation is crucial in the context of the Global Stocktake, intended to inform Parties to the Paris Agreement on their progress against its goals, including limiting the global temperature rise to 1.5°C. National Adaptation Plans also take center stage in current climate discussions, marking the launchpad for states to decipher local and national vulnerabilities and risks, plan effective adaptation actions, and secure funding. CMCC scientist Marta Ellena shares insights illuminating COP28’s ambition for a sustainable and resilient future.

Towards a nature-positive economy

“We need now to integrate private sector actors, take advantage of innovative technologies and AI, and train future generations.” Healthy and well-managed ecosystems provide a range of services that support climate change adaptation and disaster risk reduction. The achievements and upcoming priorities when it comes to nature-based solutions in the words of Nathalie Doswald.

Africa’s climate change adaptation pathway

Africa is one of the most vulnerable continents to climate change and variability, a situation which is further aggravated by its low adaptive capacity and the interaction of factors such as poverty, energy demand and rapid urbanisation.

Building on sustainable foundations: Climate change and energy efficiency to decarbonize the construction sector

The link between buildings and climate change has long been a focal point of global discussions on mitigation and adaptation. A new report by UNEP and Yale addresses the urgent need to decarbonize the construction sector, responsible for more than one third of global CO2 emissions. With global emissions on the rise, this report provides a blueprint for reducing “embodied carbon” emissions from building materials by 2050. Expert Paolo Bertoldi highlights that creating a sustainable building industry is possible and needs collaboration across sectors and countries.

Wildfires from attribution to solutions: tools and resources

Fire has always been an integral part of human civilization and a key ecosystem process. Fires influence vegetation growth, environmental conditions, and even our climate. However, a changing climate and human interactions through land change use and forest management are having an impact on the intensity and frequency of wildfires. So, what can we do about it?

Elly Vaughan: The climate-health nexus between pollen and heatwaves

The interplay between climate change, air quality and lung health is a key issue that requires innovative approaches and solutions. “It’s not just what the empirical evidence is telling us about different particle concentration levels in the air but how people are perceiving air quality,” says health policy expert at Economist Impact Elly Vaughan.
