Credit: Pixabay/CC0 Public Domain In 2015, 170 countries worldwide adopted the Paris Agreement, with the goal limiting the average global temperature increase to 1.5°C. Following the agreement, many countries and cities proposed targets for greenhouse gas mitigation. However, the UNEP Emissions Gap Report 2020 shows that, without drastic and strict […]

It may not be very well known, but the Arctic Ocean leaks enormous amounts of the potent greenhouse gas methane. These leaks have been ongoing for […]

Schindler, NASA Scientific Visualization Studio Global emissions of methane have reached the highest levels on record. Increases are being driven […]

LLNL scientists and collaborators used fingerprinting — the process of separating the relative roles of natural and human influences on global climate — to identify how greenhouse gas and particulate pollution emissions drive regional drying around the globe.

A thin section of an ice core collected at Taylor Glacier in Antarctica. The ice core samples contain tiny air bubbles with small quantities of ancient air trapped inside. The researchers use a melting chamber to extract the ancient air from the bubbles and then study its chemical composition. The […]

In the improved electrolyzer, the reaction happens in a thin layer that combines a copper-based catalyst with Nafion, an ion-conducting polymer. The unique arrangement of these materials provides a reaction rate 10 times higher than previous designs. Credit: U of T Engineering / Daria Perevezentsev Water is split into hydrogen […]

The Arctic is one of the […]
