In the next few decades, advancements in telescope technology will allow scientists to directly image Earth-sized exoplanets in Earth-like orbits around Sun-like stars. Current estimates suggest that the Milky Way alone contains around 10 billion habitable planets, making it statistically likely that some of them harbor life. Even though these distant worlds may initially appear as a single pixel in our instruments, future telescopes will be able to analyze their atmospheres, continents, oceans, icecaps, and cloud formations—bringing us closer to identifying potentially inhabited planets.

Forests play a critical role in combating climate change by regulating temperatures, purifying air and water, and supporting biodiversity. One of their most vital functions is forest carbon storage, as they absorb and retain carbon dioxide in trees and soil, helping to mitigate global warming. While oceans also serve as carbon sinks, forests offer a land-based solution that can be actively managed. However, simply planting more trees is not enough—different species provide varying benefits, and their effectiveness in carbon sequestration depends on environmental factors.

Retreating glaciers are posing a major threat to the food and water security of nearly 2 billion people globally, the United Nations warns. A new report from Unesco emphasizes that the current pace of glacial melt—described as “unprecedented”—will have far-reaching and unpredictable consequences for both developing and developed countries.

Between 2016 and 2021, researchers observed that cracks, or crevasses, at the edges of Greenland’s ice sheet grew significantly in both size and depth. This change was linked to the ice’s accelerated movement from the sheet’s center toward the ocean, a process driven by rising temperatures. This movement contributes to crevasse formation, which could set off feedback mechanisms that speed up ice loss over short timeframes.

Greenland’s ice sheet is the second-largest ice cap on Earth, and due to rising global temperatures, it is melting at an accelerating rate. While climate change has been intensifying atmospheric rivers—long streams of water vapor that transport heat and moisture from the oceans to colder regions—their impact on Greenland’s ice sheet is more complex than previously believed. A recent study suggests that under certain conditions, these weather events can temporarily slow ice loss by delivering massive amounts of snow.

The concentration of carbon dioxide in Earth’s atmosphere has been steadily rising, largely due to human activities and climate change. However, scientists have also observed an increasing difference between seasonal peaks and dips in atmospheric carbon dioxide levels. Previously, researchers believed that these carbon dioxide fluctuations were primarily caused by warming temperatures and rising CO₂ levels. However, a new study led by Colorado State University has found that agriculture—particularly the use of nitrogen fertilizer—is the dominant factor driving this widening seasonal variation.

Deep within Earth’s mantle lie two colossal structures known as LLVPs (Large Low-Velocity Provinces), whose characteristics have long intrigued geoscientists. Traditionally assumed to be similar in composition and age, recent research has revealed that these mantle features are, in fact, markedly different in both history and makeup. The study, involving researchers from Cardiff University, the University of Oxford, the University of Bristol, and the University of Michigan, used seismic data and advanced numerical models to unravel the distinct stories of the Pacific and African LLVPs.

The discussion centers on the potential of AI systems and whether they are nearing the development of AGI—artificial general intelligence. While recent achievements in gaming, text generation, and multimedia production are impressive, they have sparked debate over whether these successes indicate we are on the brink of AGI. The term itself remains loosely defined, with proponents offering varying interpretations, from systems that excel in specific tasks to those capable of broad, human-like adaptability. This ambiguity makes it challenging to determine how close we truly are to achieving AGI.

Recent research from the Max Planck Institute for Meteorology (MPI-M) challenges long-held assumptions about the Amazon rainforest’s vulnerability to rainfall disruption caused by deforestation. Published in Geophysical Research Letters, the study reveals that the Amazon may maintain stable annual rainfall levels even under extreme deforestation scenarios.

Peatlands cover only 3% of Earth’s surface yet store nearly one-third of the world’s carbon—twice the amount sequestered by all forests combined. This makes them crucial ecosystems in the fight against climate change, but only 17% currently receive protection, leaving them vulnerable to degradation that worsens our climate crisis.
