Imaggeo on Mondays: A dramatic avalanche from Annapurna South
The Annapurna massif is located in an imposing 55 km long collection of peaks in the Himalayas, which behave as a single structural block. Composed of one peak (Annapurna I Main) in excess of 8000 m, a further thirteen peaks over 7000 m and sixteen more of over 6000 m, the massif forms a striking …[Read More]
Heat waves in cities getting worse under climate change
The effects of climate change are being felt all over the world but towns and cities are feeling most hot-under-the collar, a new study finds. Cities are usually warmer than their surroundings due to the urban heat island effect where artificial surfaces absorb more heat than their natural counterparts. Coupled with the loss of the …[Read More]
Geosciences Column: How El Niño triggered Indonesia corals die-off
In the glistening waters of Indonesia, shallow corals – the rain forests of the sea – teem with life. Or at least they did once. Towards the end of 2015 the corals started to die, leaving a bleak landscape behind. An international team of researchers investigated the causes of the die-off. Their findings, published recently …[Read More]
Geosciences Column: Africa’s vulnerability to climate change
Ravaged by armed conflicts, a deep struggle with poverty, poor governance and horizontal inequality, some parts of Africa and other Global South regions are arguably the most vulnerable to the impacts of climate change. Largely reliant on natural resources for sustenance, current and future changes in temperatures, precipitation and the intensity of some natural hazards …[Read More]

GeoPolicy: What will a Trump presidency mean for climate change?
The US Presidential election this month saw Republican Donald Trump, a fierce climate sceptic, be elected into office. In wake of the election results, this month’s GeoPolicy post will take a look at Trump’s proposed actions on climate change, how likely these are to happen, and what the climate and clean technology communities could do …[Read More]
Imaggeo on Mondays: what corals can tell us about past climate change
Reconstructing past climates is a tricky task at the best of times. It requires an ample data set and a good understanding of proxies. Add into the mix some underwater fieldwork and the challenge got a whole lot harder! In today’s Imaggeo on Monday’s post, Isaac Kerlow explains how information locked in corals can tell …[Read More]
New study of natural CO2 reservoirs: Carbon dioxide emissions can be safely buried underground for climate change mitigation
New research shows that natural accumulations of carbon dioxide (CO2) that have been trapped underground for around 100,000 years have not significantly corroded the rocks above, suggesting that storing CO2 in reservoirs deep underground is much safer and more predictable over long periods of time than previously thought, explains Suzanne Hangx a postdoctoral researcher at the University …[Read More]
