Geotalk is a regular feature highlighting early career researchers and their work. In this interview, we caught up with Christo Buizert, an assistant professor at Oregon State University in Corvallis, who works to reconstruct and understand climate change events from the past. Christo’s analysis of ice cores from Greenland and Antarctica helped reveal links between climate change events from the l ...[Read More]
The EGU General Assembly brings together geoscientists from all over the world to one meeting that covers all disciplines of the Earth, planetary and space sciences. The conference is taking place in Vienna on 7–12 April 2019, providing an opportunity for both established scientists and early career researchers to present their work and discuss their ideas with experts in all fields of the geoscie ...[Read More]
These ethereal, twisted ice sculptures litter the frozen shoreline of Tempelfjorden, Svalbard, giving the landscape an otherworldly feel and creating a contrast with the towering ice cliff of the glacier and the mountains behind. They are natural flotsam, the scoured remnants of icebergs calved from the Tunabreen glacier, washed up on the shoreline. These icebergs were calved from the Tunabreen gl ...[Read More]
Dear readers, today our blog will host Ryan Stone from Lambda Films. He will tell us his story and perspective behind the camera while documenting people’s lives constantly exposed to volcanic risk. If you want to get a quick taste of today’s content, just take a long breath and watch this video: https://www.lambdafilms.co.uk/video-production/an-eclipse/. Hello Ryan, Please tel ...[Read More]
Some of the most remarkable, marginal features of permafrost – palsas – are degrading and disappearing metre by metre from North European peatlands, and are driven close to extinction by the climate change. What are these permafrost features? A palsa is a peat mound with an icy core, which stays frozen throughout summer due to the insulating property of dry peat. These mounds can rise up to 10 met ...[Read More]
Drawing inspiration from popular stories on our social media channels, major geoscience headlines, as well as unique and quirky research, this monthly column aims to bring you the latest Earth and planetary science news from around the web. Major stories Earth’s red and rocky neighbor has been grabbing a significant amount of attention from the geoscience media this month. We’ll give you the rundo ...[Read More]
Climate change has been described as “the biggest market failure in human history”[1]. Although fuel is costly, emitting the by-product CO2 is for free; yet it causes damages to society. In other words, those who benefit, by using the atmosphere as waste dump, do not pay the full costs, i.e. the adverse effects climate change has on societies on a global scale. Can this market failure be cured? Sh ...[Read More]
The Antarctic ice sheet stores a large amount of water that could potentially add to sea level rise in a warming world (see this post and this post). It is currently losing ice, and the ice loss has been accelerating in the past decades. All this is linked to the melting of ice – not at the surface but at the base, underneath the so-called ice shelves which form the continuation of the Antarctic i ...[Read More]
Common images associated with climate change include sad baby polar bears, a small Arctic sea ice extent, retreating glaciers, and increasing severe weather. Though slightly less well-known, river ice is a hydrological system which is directly influenced by air temperature and the amount and type of precipitation, both of which are changing under a warming climate. Ice impacts approximately 60 % o ...[Read More]
In three days’ time, NASA’s InSight Lander is expected to plunge through Mars’ atmosphere before parachuting down to a controlled landing on the flat plains of the Elysium Planitia. Once the dust has settled, a solar powered robotic arm will painstakingly unload the precious instruments stored onboard onto the planet’s surface, carefully guided by scientists back on Earth. These instruments are de ...[Read More]
