Volcanic eruptions may have played crucial role in dinosaur extinction

The demise of dinosaurs wasn’t solely orchestrated by a meteorite impact, as a recent study suggests. Published in Science Advances and co-authored by McGill University’s Professor Don Baker, the research challenges the conventional narrative by proposing that massive volcanic eruptions, not just a celestial collision, triggered climate change that paved the way for dinosaur extinction. … Read more

What is climate change?

Climate change is a complex and multifaceted phenomenon that has garnered significant attention in recent decades due to its far-reaching implications for the planet and its inhabitants. At its core, climate change refers to long-term alterations in temperature and weather patterns on Earth. These changes are largely attributed to human activities that have increased the … Read more

Land-based emissions estimates vary between models and inventories, new study

A new study published in Nature demonstrates that estimates of current land-based emissions vary between scientific models and national greenhouse gas inventories due to differing definitions of what qualifies as “managed” land and human-induced, or anthropogenic removals on that land, and shows how global mitigation benchmarks change when accounting for land use, land-use change, and … Read more

Southern rainfall plays a surprising role in Northern haze

The North China Plain (NCP) is a region with some of the worst air pollution conditions on a global scale. Air pollution (known as haze) dominated by higher PM2.5 concentration, is well-documented for its adverse impacts on both human health and socioeconomic progress. Despite rigorous emissions reduction measures implemented by the Chinese government, the region … Read more

New AI model predicts rogue waves

Long considered myth, freakishly large rogue waves are very real and can split apart ships and even damage oil rigs. Using 700 years’ worth of wave data from more than a billion waves, scientists at the University of Copenhagen and University of Victoria have used artificial intelligence to find a formula for how to predict … Read more

New study suggests plants may absorb more carbon dioxide than previously thought

The latest research published in Science Advances offers a surprisingly optimistic perspective on the planet’s ability to mitigate the impacts of climate change. Unlike previous predictions, more realistic ecological modeling suggests that the world’s plants might absorb a greater amount of atmospheric CO2 from human activities. However, the environmental scientists behind this research are quick … Read more

Novel statistical method improves climate model projections

Researchers from institutions including the Department of Energy’s Oak Ridge National Laboratory have created a new method for statistically analyzing climate models that projects future conditions with more fidelity. The method provides a way to adjust for models with high temperature sensitivities—a known problem in the community. By assigning different weights to models and combining … Read more

Researchers help reduce lead levels in Madagascar drinking water

A team of engineers and public health experts from the University of South Florida is helping Toamasina, Madagascar, residents reduce their exposure to lead—a major global environmental pollutant that causes more than 1 million premature deaths each year. By combining efforts to replace water pumps and educate city technicians, USF researchers helped decrease the blood … Read more
