In 1821, peat cutters discovered a body similar to a mummy, pinned down by two wooden stakes deep in the mud. The body’s face still held red hair and a beard, their teeth were well preserved, and a hoop of willow was wrapped around their throat. But this wasn’t the dry, hot climate of Egypt but a cold and rain-sodden bog of Ireland. Later assessment suggested that these were the remain ...[Read More]

2020 is being described by many as a tipping point: the year that humanity as a species must take concrete and measurable action to prevent catastrophic climate change. But even if we do manage to slow carbon emissions from 2020 onwards, how would the planet deal with all the carbon dioxide we have produced so far? How much capacity do the planet’s natural carbon sequestration reserves actually ha ...[Read More]

This magnificent pattern is the result of hundreds and hundreds of years of evolution. In this structured minerotrophic peatland in Northern Quebec (Canada), which can also be called a string fen or aapa mire, the green peat ridges (or strings) alternate with water-filled hollows (or flarks). Often flarks are replaced by ponds, which vary in number and size. This pattern of strings and flarks (or ...[Read More]

Patagonia, the region in southernmost tip of South America, is as diverse as it is vast. Divided by the Andes, the arid steppes, grasslands and deserts of Argentina give way to the temperate rainforests, fjords and glaciers of Chile. Also on the Chilean side are rolling hills and valleys of marshy topography: Patagonia’s bogs. Today, Klaus-Holger Knorr, a researcher at the University of Münster’s ...[Read More]
