An increasing global population means that we are more dependant than ever on soils. Soils are crucial to securing our future supplies of water, food, as well as aiding adaptation to climate change and sustaining the planet’s biosphere; yet with the decrease in human labour dedicated to working the land, never have we been more out of touch with the vital importance of this natural resource. Now, ...[Read More]

The EGU General Assembly was bigger than ever this year. Over 16,500 people attended more than 500 sessions. Although many sessions featured policy-relevant science, the short course entitled ‘Working at the science policy interface‘ focused purely on the role of scientists within the policy landscape. For those of you that couldn’t attend, this month’s GeoPolicy post takes a clo ...[Read More]

Understanding where we come from and whether Earth is the only habitable planet in the Solar System has been a long standing conundrum in science. Partly because it is our nearest neighbour, partly because of its past and current similarities with our own home, Mars, the red planet, is a likely contender in the quest for extra-terrestrial life. In this guest blog post, James Lewis, a PhD student a ...[Read More]

The air we breathe is full of tiny particles that can have a big impact on our climate. Industrial activities have greatly increased the number of these particles, cooling the climate and potentially offsetting some of the warming due to greenhouse gases. In this post Kirsty Pringle introduces new research that suggests that it might not be possible to quantify the effect of industrial emissions o ...[Read More]
