The trillion-dollar question behind corporate net-zero pledges‎

Corporate climate spending now steers trillions of dollars in transition finance worldwide. Does it drive genuine climate action? Research shows that accounting flexibility alone can make a company's reported emissions vary by roughly a factor of two—enough to appear either as a climate leader or a laggard. A new perspective in Nature Sustainability proposes developing industry-specific net-zero blueprints to close that gap.

Rain dampens France fire, as Spain reports 'almost no flames'‎

Firefighters in France on Thursday were hopeful a massive forest fire was no longer spreading, as Spain said there were "almost no flames" left after a similar blaze near Madrid.

From single projection to many possibilities: A new tool for climate risk assessment‎

Assessing how climate change will affect different regions usually requires running a complex chain of models. While this approach provides valuable insights, it is expensive and can cover only a limited set of scenarios and model runs. Together with partners, IIASA researchers have developed a faster alternative that uses available projections from Earth system or climate impact models to generate new regional climate and impact projections while capturing the uncertainty essential for understanding climate risk.

Chicken kidney sponge could be 'outstanding' at cleaning up polluted ports‎

Ports rank among the most disturbed marine environments. Pollutants like trash, oil and toxins from antifouling paints tend to accumulate in enclosed harbors. Invasive species arriving in ballast water may displace native wildlife, while ship propellers, sonars and dredging cause noise pollution that can interfere with animal communication. There is thus a great need for effective ways to clean up harbors. One promising method is renaturalization, in which hardy species that can survive under these conditions are deliberately introduced to act as pioneers.

Three-dimensional visualization of nanoplastic distribution in the neonatal mouse brain‎

Nanoplastics—plastic particles smaller than one micrometer—are generated through the degradation and abrasion of plastic products and are increasingly detected in food, drinking water, air and biological tissues. Although the presence of plastic particles in animals and humans is well-established, determining how nanoplastics are distributed within complex organs, such as the brain, remains challenging.
