Teacher's guide book for primary and secondary school

There is an urgent need for collective action to mitigate the consequences of climate change and adapt to unavoidable changes. The complexity of climate change issues can pose educational challenges. Nonetheless, education has a key role to play in ensuring that younger generations have the required knowledge and skills to understand issues surrounding climate change, to avoid despair, to take action, and to be prepared to live in a changing world. The Office for Climate Education (OCE) was founded in 2018 to promote strong international cooperation between scientific organisations, educational institutions and NGOs. The overall aim of the OCE is to ensure that the younger generations of today and tomorrow are educated about climate change. Teachers have a key role to play in their climate education and it is essential that they receive sufficient support to enable them to implement effective lessons on climate change. The OCE has developed a range of educational resources and professional development modules to support them in teaching about climate change with active pedagogy

3. Des prévisions météorologiques aux projections climatiques

Origines et sources de prévisibilité La première source de prévisibilité dite « de première espèce » découle des conditions initiales du système à prévoir (e.g. l’état dynamique et thermodynamique de l’océan et de l’atmosphère). La deuxième source dite « de deuxième espèce » est issue des conditions aux limites de ce système (forçage solaire, gaz à effet de serre*, etc.). Appliquée au climat, la connaissance des conditions aux limites permet de déterminer la distribution statistique d’une var..

The Role of Atmosphere Feedbacks During ENSO

International audienceAlthough most current coupled general circulation models (GCMs) exhibit some sort of ENSO signal, there are still many areas for improvement. For example, the models generally simulate El Niño events with frequencies which are too high, structures which extend too far to the west, and a large diversity of amplitudes. Moreover, simulating the correct ENSO properties with the right balance of mechanisms and feedbacks is still a challenge. Several recent studies using ocean-atmosphere GCMs suggest that the atmospheric component, and in particular the deep convection scheme, plays a dominant role in the modeled ENSO. To help elucidate these findings, the two main atmosphere feedbacks relevant to ENSO, the Bjerknes positive feedback (μ) and the heat flux feedback (α), are here analysed in 12 coupled GCMs from the CMIP3 database. We find that the models generally underestimate both feedbacks, leading to an error compensation. The strength of α is inversely related to the ENSO amplitude in the models and the latent heat and shortwave flux components of this feedback dominate. While the latent heat feedback is primarily responsible for this inverse relationship, errors in the shortwave flux feedback are the main cause of the model diversity in the overall α. In the tropical Pacific, the shortwave flux feedback is intrinsically linked to the large-scale vertical motion, with SST anomalies in the East Pacific coupled to changes in the amount of deep convection/subsidence and cloud cover. We thus propose that an improved atmosphere-ocean heat flux feedback in the models can only be achieved by correcting the errors in the convection/cloud physics responsible for the biases in the shortwave flux feedback
