Climate Change -and the transition to a zero-emission society

The climate change is probably the most complex planetary challenge that humanity is facing today. Despite of the large number of authoritative scientific reports that show its acceleration, its growing risks, and the progressive reduction of the window of opportunity to act towards cost-effective and equitable solutions, very few steps have been done, towards this, by the international community.

This series of videos, which is based on 6 public seminars given by Andrea Tilche* at UiT, during the winter and spring of 2019, endeavours to open a broader discussion on this very subject. Through an approach of looking at the physical, ideal, political, economic and social roots of the problem, in order to frame a proposal for the transition into a more sustainable zero-carbon society where Universities, as sites of cultural development and new generations are essential actors of change, have an essential role to play.

Anne Husebekk, Rector of UiT The Arctic University of Norway, provides here an introduction to this series of podcasts on climate change.

Introduction
The climate movements are also proposing a lexical change to the traditional narrative on global warming, its causes and consequences. The term “climate emergency” is more and more adopted. I did not systematically use this...

Podcast 1: Climate change and the greenhouse effect
Here I provide some of the basics that allow to understand how emissions of greenhouse gases caused by human activities, and in particular by the burning of fossil fuels during the last 250 y after...

Podcast 2: Past climate
The climate on Earth has changed very frequently in the past, and the analysis of the past climate and of its changes is essential in order to understand what is happening today because of human...

Podcast 3: Carbon emissions and the carbon budget
In 2018 the Earth was already in average about 1°C warmer than in pre-industrial times. Emissions of CO2 and of other greenhouse gases are continuously growing, and the amount of CO2 that remains possible to...

Podcast 4: Why is it necessary to halt global warming?
The planet is warming very rapidly, is this so much of a problem? Yes, it is. The very rapid warming is already changing the geography of Earth – with its geophysical, biological, economic and social...

Podcast 5: Decarbonisation is possible
If decarbonisation is an obligation, the key issue is how to design it in order to make it cost-effective, just, rapid and stable. Here we explore the dimension of the challenge, its history, the current...

Podcast 6: Decarbonisation challenges
Decarbonisation strategies have to analyse the sectoral challenges, but have to develop integrated solutions, thinking ahead of what will be the energy sector of tomorrow, when all the current uses of fossil fuels will have...

Podcast 7: Climate change science and policy-making
Climate change science is a science of complexity, and it is characterised by its exploration of the future through forecast models, and by the thorough treatment of uncertainty. However, it is also because of its...

Podcast 8: Why are we waiting?
The UN Framework Convention on Climate Change was established in 1990, and after 30 years we are still waiting for the operationalisation of the Paris Agreement, that at the level of ambition pledged by participating...

Podcast 9: Worldviews and the climate emergency
Halting global warming and keeping the planet on sustainable tracks is not something that can be obtained just through technological fixes. Technology is very important, but it cannot be the only response, and not even...
