What happens to monsoon raindrops before they reach the ground?

What happens to monsoon raindrops before they reach the ground?

Using stable isotopes to uncover a hidden step in Earth’s water cycle The Indian summer monsoon transforms South Asia’s landscape. Rivers swell, reservoirs replenish, crops receive life-sustaining water, and millions await relief after months of intense heat. But what happens to a raindrop between the cloud and the ground? Not every raindrop reaches the surface …[Read More]

How long does an ecosystem remember the weather?

How long does an ecosystem remember the weather?

“Plants carry traces of past weather. Reading them may help us navigate a hotter, drier world.”  Wenli Zhao As global warming intensifies drought frequency, understanding how ecosystems store and deplete water is critical for anticipating vegetation stress. This blog walks us through a novel groundbreaking study published on EGU journal Hydrology and Earth System Sciences …[Read More]

A geoscience reality check on World Biofuels Day

A geoscience reality check on World Biofuels Day

On a humid morning in Augsburg, Germany, on August 10, 1893, a ten-foot iron cylinder roared to life for the first time. The engine belonged to Sir Rudolf Diesel, and running through its veins was not the petroleum distillate we associate with his name today, but in fact, peanut oil! Diesel’s early experiment proved something …[Read More]

Reflecting on fifty years of Mars through Viking 1’s lens

Reflecting on fifty years of Mars through Viking 1’s lens

On July 20, 1976, a machine of steel and titanium dropped through a thin atmosphere and touched the dirt of Chryse Planitia. Scientists at NASA held their breath, since five years earlier, the Soviet Union’s Mars 3 probe had died less than two minutes after touchdown. To mitigate this nightmare, engineers programmed Viking 1 to …[Read More]

Interdisciplinary futures in geoscience: Cross-divisional insights from the Division Presidents – Atmospheric Sciences (AS)

Interdisciplinary futures in geoscience: Cross-divisional insights from the Division Presidents – Atmospheric Sciences (AS)

This interview is part of an ongoing series exploring the evolving role of interdisciplinarity across the geosciences. As environmental challenges grow more complex, addressing them requires not only disciplinary expertise but also meaningful collaboration and innovation across fields, methodologies, and communities. In each conversation, I ask Division Presidents to reflect on how cross-divisional work is …[Read More]

Ozone 101: What you need to know as the Montreal Protocol turns 35

As the world commemorates the 35th anniversary of the Montreal Protocol, it’s worth taking a moment to appreciate this landmark agreement’s monumental impact on our planet. Officially known as the “Montreal Protocol on Substances That Deplete the Ozone Layer,” this treaty stands as one of the most successful environmental accords in history, showcasing what humanity …[Read More]

The varying composition of a single bolt of lightning

The varying composition of a single bolt of lightning

Until recently, scientists assumed lightning had a homogeneous distribution of energy inside its channel. But researchers like Damien Bestard, a PhD student with the Sorbonne Université have found that the composition of each bolt is quite variable. Bestard presented his findings at the European Geosciences Union General Assembly EGU23 on Monday (April 24). As part …[Read More]
