Rivers, on a long view, are alive. They are born; they change; they shift their channels; they forge new routes to the sea; they move both gradually and violently; they can teem (usually) with life; they may die a quasi-natural death; they are frequently maimed and even murdered. It is the annual flood pulse—the brief time when the river occupies the floodplain—that gives a river its vitality, but it is human engineering that kills it, suppressing the flood pulse with dams, irrigation, siltation, dikes, and levees.

In dit hoorcollege bespreken Jan Willem Erisman en Wim de Vries de historie en de oorsprong van de stikstofproblematiek, met daarbij aandacht voor de modellen en metingen die ons in staat stellen de uitstoot en depositie van stikstofverbindingen in te schatten. Ze gaan in op de stikstofcyclus en de gevolgen van de stikstofovermaat voor lucht-, bodem- en waterkwaliteit, en daarmee voor natuur, gezondheid en klimaat. Daarnaast staan ze stil bij de mogelijke oplossingen van het probleem. Waar en hoe kunnen we de stikstofuitstoot verminderen? Met hoeveel?

Esta provocadora pregunta es el núcleo de Creadores de tormentas, un análisis profundo sobre las teorías de la conspiración relacionadas con la manipulación climática, la geoingeniería y las tecnologías que, según algunos, ya están cambiando nuestro mundo.

What if climate change isn’t an environmental challenge, but an energy challenge? In this visionary book, Dr Tim Gregory urges us to rethink the path to net zero. He argues that the solution to climate change lies not simply in replacing fossil fuels with renewables, but in fully embracing another energy source that emits zero carbon dioxide: nuclear power.

For over two centuries, as rulers have risen and fallen and wars have raged, one majestic oak tree has lived out an epic drama. From germination in 1780 to adapting to the changing climate of the modern age, its struggles and triumphs took place far from human eyes. That is, until one day a young man named Laurent Tillon came across it, and a decades-long relationship began ... In this dazzling book, biodiversity expert Tillon narrates the story of the tree he calls Quercus

In 2011, a young wolf named Slavc set out from Slovenia. Tracked by GPS, he travelled a thousand miles through the Alps, arriving four months later on the Lessinian plateau, north of Verona. There had been no wolves in northern Italy for a century, but here he crossed paths with a female wolf on a walkabout of her own. A decade later and there are more than a hundred wolves back in the area, the result of their remarkable meeting. In Lone Wolf, Weymouth walks Slavc's path, examining the changes facing these wild corners of Europe.
