New research utilizing radar data from space has revealed alarming insights about the Thwaites Glacier in West Antarctica, commonly known as the “Doomsday Glacier.” This study, published in the Proceedings of the National Academy of Sciences, highlights a significant increase in the vulnerability of the glacier, as ocean water is found to be pushing miles beneath it. This process is causing vigorous Doomsday Glacier melting, which might mean that the current projections for global sea level rise are considerably underestimated.

A recent study highlights the severe Amazon rainforest drought impact, showing that over a third of the Amazon is struggling to recover from persistent drought conditions. This research, detailed in the Proceedings of the National Academy of Sciences, underscores a critical slowing down of the forest’s resilience, pushing it towards a potential irreversible degradation. The findings are particularly alarming as the Amazon serves as the world’s largest terrestrial carbon sink and a pivotal element in global climate regulation.

In August 2021, an unprecedented event occurred at the Greenland ice cap’s summit, where rain caused significant melting and retreat of the snowline, highlighting the growing frequency and impact of Arctic rain-on-snow events. This event prompted Joel Harper, a glaciologist at the University of Montana, to revisit earlier anomalies in his data from 2008, confirming it had rained significantly late in the season.

Last weekend’s skies lit up with a stunning display of the aurora borealis, visible as far south as Alabama, thanks to a powerful coronal mass ejection. This celestial phenomenon, typically confined to polar regions, underscores the dramatic effects that solar activities can have on Earth. Coronal mass ejections are not only beautiful but also bear potential hazards, as their interaction with Earth’s magnetic field can lead to disruptions in satellites, GPS systems, power grids, and telecommunications.

A recent analysis of cloud data from the California coast, along with global satellite observations, highlights the significant role of aerosol particles as small as 25–30 nanometers in cloud formation. This challenges previous assumptions and suggests that the climate impact of tiny aerosols may have been underestimated.

Forests are crucial for sustaining Earth’s biodiversity and are key in absorbing atmospheric carbon dioxide, offering vital ecosystem services as defenses against climate and biodiversity crises. However, a significant knowledge gap exists due to most global forest data coming from low to medium resolution satellite imagery, which inadequately covers dynamic and dispersed forest systems such as agroforestry, drylands, and alpine forests.
