GeoTalk: Want a record of historical floods? Ask the taxman

Extreme weather events, like catastrophic floods, are the malicious exclamation points of Earth’s chaotic and variable climate system; they arrive without warning and extract huge costs, both economic and humanitarian, from the communities they strike. Evidence suggests the frequency and severity of these events may be on the rise in a changing climate, but scientists struggle to place modern even ...[Read More]

Defining the age of humans

We are currently changing our planet like never before. But do these changes deserve a new name? The Anthropocene – a geological period marking the length of time for which humans have had a significant impact on the planet – was first proposed in the 1980s. But the word has gained significant attention in recent years thanks to the popularising work of Nobel prize-winning chemist Paul Crutzen. Hu ...[Read More]

It’s not my fault

A line on a map is important. In the Beverly Hills region of Los Angeles a series of mapped fault lines are now the cause of a major controversy. Communities have been alarmed, money has been lost and legal proceedings are ongoing. It started in 1992. James Dolan and Kerry Sieh, two earthquake geologists at the California Institute of Technology, published a map in a field trip guidebook about the ...[Read More]

Meltwater ponds halt new sea ice growth

Each September, battered by the relentless sun-filled days of summer, the smooth expanse of the Arctic Ocean reaches the climax of its annual transformation. Replacing the endless blanket of winter ice, a vast jigsaw puzzle stretches across the pole, a mosaic of soggy snow islands floating amid turquoise ponds of meltwater and inlets of dark blue sea. These meltwater ponds have been shown to drama ...[Read More]
