Major climate-GDP study under review after facing challenge

A blockbuster study published in top science journal Nature last year warned that unchecked climate change could slash global GDP by a staggering 62% by century’s end, setting off alarm bells among financial institutions worldwide.

But a re-analysis by Stanford University researchers in California, released Wednesday, challenges that conclusion—finding the projected hit to be about three times smaller and broadly in line with earlier estimates, after excluding an anomalous result tied to Uzbekistan.

The saga may culminate in a rare retraction, with Nature telling AFP it will have “further information to share soon”—a move that would almost certainly be seized upon by climate-change skeptics.

Scientists Discover the Explosive Chain Reaction That Triggers Lightning

Lightning may look like a sudden burst from the clouds, but its true origin lies in an invisible storm of cosmic rays, X-rays, and high-energy electrons. A breakthrough study led by Penn State researchers has finally decoded this hidden process: when cosmic rays strike thunderclouds, they trigger

Climate-protecting carbon sinks of EU forests are declining

Forests cover about 40% of the EU’s land area. Between 1990 and 2022, they absorbed around 10% of the continent’s man-made carbon emissions. However, the carbon dioxide absorption capacity of forests, also known as carbon sinks, is becoming increasingly weaker.

This is shown by calculations of multi-year carbon budgets by an international team of researchers in a recent Nature study. The continuous decline in the carbon sink of our forests jeopardizes the EU’s climate targets. To halt or reverse the trend, the authors recommend practical measures in research and forest management.

Forests absorb (CO₂) from the atmosphere, which they use for their metabolism and convert into biomass. Healthy and growing forests therefore act as carbon sinks, storing climate-damaging CO₂ from the atmosphere in the long term.

Particle pattern reveals how desert dust facilitates ice formation in clouds

A new study shows that natural dust particles swirling in from faraway deserts can trigger freezing of clouds in Earth’s Northern Hemisphere. This subtle mechanism influences how much sunlight clouds reflect and how they produce rain and snow—with major implications for climate projections.

Google DeepMind says its new AI can map the entire planet with unprecedented accuracy

Google DeepMind unveils AlphaEarth Foundations, an AI system that processes satellite data 16x more efficiently to create detailed Earth maps for tracking deforestation, climate change, and environmental shifts.

Astronomers Stunned As Mysterious Flare Repeats From Same Black Hole Two Years Later

A new discovery challenges the previously accepted understanding of how stars interact with black holes. While it’s often said that lightning never strikes the same place twice, black holes seem to defy that rule. A team of astronomers, led by researchers from Tel Aviv University, has observed a
