A gripping new investigation into the underbelly of digital technology, which reveals not only how costly the virtual world is, but how damaging it is to the environment.If digital technology were a country, it would be the third-highest consumer of electricity behind China and the United States.Every year, streaming technology generates as much greenhouse gas as Spain - close to 1 per cent of global emissions.One Google search uses as much electricity as a lightbulb left on for up to two minutes.It turns out that the 'dematerialised' digital world, essential for communicating, working, and consuming, is much more tangible than we would like to believe. Today, it absorbs 10 per cent of the world's electricity and represents nearly 4 per cent of the planet's carbon dioxide emissions. We are struggling to understand these impacts, as they are obscured to us in the mirage of 'the cloud'.The result of an investigation carried out over two years on four continents, The Dark Cloud reveals the anatomy of a technology that is virtual only in name. Under the guise of limiting the impact of humans on the planet, it is already asserting itself as one of the major environmental challenges of the twenty-first century.

Navigating institutions and donor requirements to successfully access international climate finance is challenging for many countries. Establishing national climate funds can be a way to meet these challenges, ensuring the targeted use of funds and strengthening ownership. This book examines the establishment of two national climate funds in Brazil, the Low Carbon Agriculture Programme and the Amazon Fund. Their establishment must be seen against the background of a drastic shift in Brazilian climate policy, enabled by discursive changes, during the administration of the Workers' Party 2003 - 2016. Dr. Ursula Flossmann-Kraus is a climate finance specialist and has led and implemented projects and programmes for GIZ and the Commonwealth Secretariat.

Have you ever relied on the kindness of strangers? What brings people together to find hope and solidarity? What do we owe each other as citizens and comrades?Questions of care, intimacy, education, meaningful work, and social engagement lie at the core of our ability to understand the world and its possibilities for human flourishing. In Lean on Me feminist thinker Lynne Segal goes in search of hope in her own life and in the world around her. She finds it entwined in our intimate commitments to each other and our shared collective endeavours. Segal calls this shared dependence ‘radical care’. In recounting from her own life the moments of motherhood, and of being on the front line of second-wave feminism, she draws upon lessons from more than half a century of engagement in Left feminist politics, with its underlying commitment to building a more egalitarian and nurturing world. The personal and the political combine in this rallying cry to transform radically how we approach education, motherhood, and our everyday vulnerabilities of disability, ageing and enhanced needs.Only by confronting head-on these different forms of interdependence and care can we change the way we think about the environment and learn to struggle – together – against impending climate catastrophe.

Increasing irrigation efficiency has been high on the political agenda in Spain for many years. However, the overarching aim to reduce agricultural water consumption has not been met so far. To explore this phenomenon, Nora Schütze investigates processes of coordination between the water and agricultural sector in three Spanish river basins in the context of the EU Water Framework Directive implementation. From the perspective of polycentric governance, she identifies multiple mechanisms which illustrate how and why actors interact in certain ways, and thus shows why environmental aims of the Water Framework Directive remain unachieved.
