In the past 66 million years, Earth's climate has continuously changed due to the movement of tectonic plates, periodic cycles driven by Earth's orbital processes and abrupt climate shifts. This talk focuses on the rare, abrupt and extreme climate shifts in the Earth's system which are speculated that they could have occurred due to the passing of a "tipping point".

In this webinar, Beniamino Abis focuses on the basics of climate and climate change, and on how students can help, learn, and make a difference through the Climate Detectives initiative organised by ESA. It also addresses the difference between weather and climate, underlines the importance of the atmosphere, gives examples of how climate change is already affecting the planet and how it might affect future scenarios, and showcases how scientists study and observe the Earth.

Why do we need an energy revolution? How can we benefit from it and how can we make it happen? In this webinar, Diana S�sser will discuss energy transition and present different options for using renewable energies to create a greener future for ourselves. She will explain why this transition is essential to fight climate change and discuss its current challenges and limitations.

In this webinar, Katinka Bellomo explains what clouds are, how they form and their role in the current climate and in climate change. The contents vary slightly depending on the age of the students.

About a third of all the food produced never reaches a human stomach. In this webinar, we will explore food waste and what we can do to minimize them. We will also dive deeper on how my scientific research intertwines in this aspect. I'd love to interact with students, therefore it would likely be a 20-30 min talk followed by a Q&A session. The webinar can be tailored according to students' interests.

This webinar touches upon several topics related to climate change. In particular, the following themes are discussed: - Causes and main consequences of climate change - Risk perception - Individual vs. collective actions - Scientific consensus and climate skepticism - Climate justice The whole presentation lasts approximately 4 hours and can be easily split into two parts. Alternatively, a short version is available, with a reduced number of topics. The webinar is not meant to be a frontal lecture, but rather an interactive session. Students participate in a quiz, in which they are encouraged to voice their opinions.

Whenever an animal encounters harsh environmental conditions, it can move/migrate in search for a new environment with better ones (even if transiently). Plants, however, don't have that ability. How do they survive, then, in such a variety of environmental conditions? In this seminar, Maria Cecilia Costa will discuss the adaptations that allow plants (some better than others) to adapt to harsh environments, either because of the cold of because of the low availability of water. She uses examples like Siberian and South African plants to compare extreme scenarios and offers an interactive chat with the students in which they can think of their own questions about plan adaptations

Is a fairer and more sustainable agriculture possible? An agriculture that meets the challenges of food security but also those of climate change and biodiversity erosion? Is agroecology really an option to feed the 9.8 billion people in 2050? This seminar presents the latest scientific findings on these issues and highlights the role of agrobiodiversity and family farming system in building a fair and equitable sustainable agriculture.

Présentation et deux parties et en en français des enjeux écologiques et sociaux du déréglement climatique : - C'est quoi le climat ? - Quels sont les impacts du réchauffement climatique ? - à quoi sont dus ces changements ? - Quelles pourraient en être les conséquences ? - Tous impactés pareil ? - Quid de nos objectifs ? - Futur possible des émissions de GES - Une responsabilité partagée équitablement ? - Quels efforts requis pour nos sociétés ? - Quels leviers d'action pouvons-nous mettre en place ? - Une démarche personnelle peut-elle suffire ? - Ma démarche personnelle, mon projet professionnel, notre projet de société.

More and more, we hear things like 'droughts are becoming more likely' or 'floods are expected to happen more often', especially when one of these events happens. But how do scientists calculate this? How do we know and understand what a changing climate means? And maybe more importantly - what don't we know yet?
