Dealing with complexity and chaos in climate

Nobel Prize in Physics 2021 (Part II)

Sala 1.4.14, Ciências ULisboa

Por Pedro Miranda (Instituto Dom Luiz).

The development of weather forecasting, first, and later of climate forecasting, raised a number of fundamental issues on the level of complexity that was required to obtain sensible results, and even on the viability of such forecasts in the long range. In the 1960s, the revelation of the presence of chaotic dynamics in atmospheric equations, coming in particular from the pioneering work of Eduard Lorenz, appeared to significantly constrain the future progress in atmospheric prediction. However both weather and climate experienced dramatic progress in their forecasting ability in the following decades, still ongoing. Syukuro Manabe and Klaus Hasselmann made key contributions to these remarkable developments. Manabe (already a recipient of the Crafoord prize) developed the first model capable to compute the impact of increasing CO2 in climate, incorporating the interaction of CO2, water vapor and convection, and later the first coupled atmosphere-ocean model. Hasselmann explored the interaction between weather and climate, showing that it leads leads to a slowly evolving system, more amenable to long range prediction.

Short Bio: Pedro Miranda studied Physics at the University of Lisbon and completed his PhD at the University of Reading (UK) in 1991, with a thesis on atmospheric internal waves. His research has focused on the development and application of numerical models to atmospheric and ocean processes, including mountain waves, atmosphere-surface and atmosphere-ocean interactions, tsunami propagation, global and regional climate, and water vapor dynamics.

A ULisboa promove o Dia Aberto M23, um evento que pretende aproximar o público adulto do meio universitário.

In this course, we promote a multidisciplinary approach presenting the most recent findings on the topic and challenging the traditional way of considering symbiotic associations as exceptions and not as the rule.

The goal of this course is to provide to the participants with current and practical knowledge on urban ecology, including ecological and social aspects.

Neste encontro, vamos descobrir as potencialidades da utilização do Jamboard - um quadro branco digital gratuito da Google - em trabalhos colaborativos.

Nesta formação, aprenderemos a criar apresentações dentro do Mentimeter, a criar diferentes tipos de slides e a selecionar as configurações mais adequadas aos objetivos pedagógicos.

Nesta formação, iremos abordar as diferentes etapas do processo de planificação de unidades curriculares e refletir conjuntamente em boas práticas sustentadas pela investigação.

1.ª edição desta formação avançada, com candidaturas a decorrer.

This course aims to explore ways of communicating science to non-specialized audiences, such as policy makers, industry, general public (including students and teachers), through their engagement and participation in citizen science activities.

O evento pretende juntar técnicos, investigadores, estudantes, produtores, industriais e demais agentes da fileira, contribuindo para a atualização de dados sobre o setor e a partilha de conhecimentos sobre as potencialidades da flora portuguesa, para além, das condições edafoclimáticas nacionais que potenciam produtos de elevada qualidade.

Um curso de cibersegurança direcionado para executivos e decisores de organizações públicas e privadas, civis e militares.

This course introduces the field of island biogeography, a discipline that has long influenced other research areas such as macroecology, community ecology, evolution and conservation biology.

Scientists, as the main actors in the production of scientific knowledge, have the responsibility of having an active voice in communicating this knowledge – and that can be achieved for example by a conscious use of the communication tools at their disposal and a better articulation with journalists, among other means.

This course aims at providing students with basic knowledge of R programming, allowing them to manipulate and visualize data with R.

This course aims at providing students with statistical knowledge and tools to manipulate, analyze and visualize biological data with R. It also includes an introduction to modeling, simulations and Bayesian statistics.

Under the general framework of Global Change Ecology, the goal of this course is to provide the participants with the most recent and practical knowledge on the use of Functional Diversity.

The course provides essential skills and knowledge that enable the participants to develop climate change adaptation strategies.

The objective of this course is to provide participants with basic knowledge on a) the fundamental aspects of experimental design and b) workflows, platforms and tools to increase reproducibility at all scientific levels.

This is a mostly practical course offering an overview on different community ecology and macroecological methods and software. These will include all steps of a research project, from the optimal sampling of communities to process inference from large-scale patterns of taxon, phylogenetic and functional diversity.

This course aims to walk through the grounds of modern botany studies, covering subjects that have been excluded from most academic curricula.

The course aims at enabling the participants to use different methods to measure the impacts of pollutants on ecosystems. Basic knowledge will be provided through theoretical and practical lessons on how to select and use the most suitable metrics based on the analysis of multiple compartments of the ecosystems.

This course offers an overview of the different ways to measure biodiversity, and provides tips for the stratification of primary biodiversity data and the construction of variables that describe its various facets. It also includes an in-depth review of the different types of data used to measure biodiversity and their problems and limitations.
