Geosciences Column: Using tall trees to tot up tropical carbon

Forests in the tropics account for about half the above-ground carbon on Earth and as the trees grow older they are capable of storing more and more. In fact, their carbon-storing potential is so large that they are increasingly being viewed as a means of mitigating climate change. Take, for example, the United Nations effort to reduce degradation and deforestation by assigning value to forest car ...[Read More]

Geosciences Column: Getting a handle on glacial lakes

Glacial lake outburst floods (GLOFs) are caused when masses of meltwater are released from behind a glacier moraine. Moraines are piles of unconsolidated debris that have either eroded from the glacier valley or have been deposited by melting glaciers. When they fail, a huge volume of water can be released, threatening populations further down the valley. Moraine failure can be caused by avalanche ...[Read More]

Geosciences Column: Climate-impact studies and their importance in a world of climatic uncertainty

A new hydrological climate-impact study by Nina Köplin and colleagues, in the European Geosciences Union journal Hydrology and Earth System Sciences, investigates the impacts of climate change on forest expansion and glacier retreat in Switzerland. This study raises important questions as to whether or not land cover changes should be considered as climate change impacts on hydrological systems, N ...[Read More]

Geosciences Column: Stitching the seafloor together

You’re standing on a mountain peak, with a fabulous field site before you. Wanting to capture the moment, you take out your iPhone, snap a dozen pictures and your mobile stitches them together beautifully – a nice record to show your colleagues back in the office. Unfortunately, not all field sites are so easy to capture – especially when you need to do a little science with the images. Seafloor p ...[Read More]
