#mineralmonday: tiptopite

Mike Jollands September 16, 2019

#mineralmonday: your weekly* dose of obscure mineralogy, every Monday** [*not guaranteed; **or possibly Tuesday-Sunday] What is it? Tiptopite: K2Na1.5Ca0.5Li3Be6(PO4)6(OH)2•(H2O) What’s it made of? Take a deep breath and recite after me: potassium, sodium, calcium, lithium, beryllium, phosphorus, oxygen and water (H2O). Is it pretty? Yes, it’s a beautiful fibrous mineral. You wouldn’t put it on …[Read More]

Imaggeo on Mondays: How do Earth’s Northern Lights form?

Konstantina Nakoudi September 16, 2019

Aurora Borealis, which means Northern Lights are caused by electrically charged particles from the sun, which enter the Earth’s atmosphere and collide with gases such as oxygen and nitrogen. When the charged particles are blown towards the Earth by the solar wind, they are largely deflected by the Earth’s magnetic field. However, the Earth’s magnetic …[Read More]

Climate Change & Cryosphere – Why is the Arctic sea-ice cover retreating?

David Docquier September 13, 2019

The Arctic Ocean surface is darkening as its sea-ice cover is shrinking. The exact processes driving the ongoing sea-ice loss are far from being totally understood. In this post, we will investigate the different causes of the recent retreat of the Arctic sea-ice cover, using the most updated literature… Arctic sea ice is disappearing Due …[Read More]

A brighter future for the Arctic

Patrik Winiger and Dasaraden Mauree September 13, 2019

This is a follow-up from a previous publication. Recently, a new analysis of the impact of Black Carbon in the Arctic was conducted within a European Union Action. “Difficulty in evaluating, or even discerning, a particular landscape is related to the distance a culture has traveled from its own ancestral landscape. As temperate-zone people, we …[Read More]

Abrupt Warming could bring our planet a “Hothouse Earth” with catastrophic consequences for our economy and society

Davide Faranda September 9, 2019

Most of us have enjoyed swings in childhood. Some have even tried to swing faster and make a full 360 degrees’ loop. Those who succeeded had a very strange feeling of not being able to predict whether, increasing the energy of the swing, the transition from normal oscillations and 360 loops would happen. Indeed, there …[Read More]
