Greenland’s largest glacier, Jakobshavn Glacier, may be edging closer to a critical threshold as meltwater runoff from the Greenland Ice Sheet accelerates in ways not seen in over a century, according to new research published […]

Sea level can temporarily change for a variety of reasons—atmospheric pressure shifts and water accumulation from wind and storms, for example—which can cause flooding in coastal communities and affect maritime industry operations. The key to […]

Cyanobacteria, as they still exist today, were the first organisms to carry out photosynthesis and release oxygen. Produced in primeval oceans about 2.5 billion years ago, this oxygen accumulated in Earth’s atmosphere on an immense […]

For scientists who study the Southern Ocean, a long-standing silver lining in the gloomy forecast of climate change has been the theory of iron fertilization. As temperatures rise and glaciers in Antarctica melt, ice-trapped iron […]

We know Aotearoa New Zealand is home to many geographically and biologically special features. Yet few of us know it also has its very own measure of “deep time.” Known as the New Zealand Geological […]

Climate change is having a profound impact on the Arctic. We know that the region is warming significantly faster than the global average, resulting in the melting of sea ice and disrupted habitats.This post was […]

Eastern Canada has seen a rise in the number of hurricane- and near-hurricane strength events battering its maritime areas, with particularly violent storms in 2003 (Hurricane Juan), 2019 (Dorian) and 2022 (Fiona). While this seems […]

Beaver dams are critical to river health and a source of biodiversity. They create wetlands, slow water and improve water quality. They also reduce flood peaks and delay runoff. But beaver dams are often blamed […]

A new study has identified a distinct climate precursor in the Mediterranean Sea that can predict winter precipitation levels in the Levant months in advance. The study, published in Weather and Climate Dynamics, is titled […]

Hike north on the Appalachian Trail and the scenery slowly transforms. Rugged, steep ridgelines in Tennessee and Virginia soften into the broad summits and smooth peaks of Pennsylvania and New Jersey. According to new research […]
