Permafrost thaw: it’s complicated
Thursday, 27 January 2022 14:00
One of the many serious consequences of the climate crisis is that precious permafrost is thawing, and this is unleashing even more carbon to the atmosphere and further exacerbating climate change. However, it’s complicated. For example, sometimes permafrost can thaw rapidly and scientists are unsure why and what these abrupt thaws mean in terms of feedback loops. This makes it difficult to predict the future impact on the climate. Thanks to an ESA–NASA initiative, new research digs deep into understanding the complexities of permafrost thaw and how carbon is released over time.

Volcano and impact craters seen in geologically rich new image from ESA's Mars Express
Thursday, 27 January 2022 11:51
At first glance, two contrasting circular features jump out of this scene: a volcano that rises gently above the surface with a collapsed caldera system, and an impact crater that digs down below. Both features have different stories to tell.
Volcano in a lava sea
Lying in the shadows of the Solar System's largest volcano, Olympus Mons, the much smaller Jovis Tholus shield volcano bears its own evidence of a long eruptive history.
Its complex caldera system comprises at least five craters. The largest is about 28 km wide, and sits off center, as clearly seen in the plan view images. The calderas step down towards the southwest where the youngest eventually meets with the surrounding sea of even younger lava flows. The lavas create a shoreline around the flanks, obscuring the original relief of the volcano, which now only sits about 1 km above the surrounding plains.
