In a recently published study, researchers show there’s a common atmospheric circulation pattern linking extreme weather on the two sides of the Atlantic Ocean.

Earth’s carbon cycle is heavily influenced by ecological processes in the ocean. The quantification and understanding of the intricate relationships between carbon dioxide and ocean ecosystems, EXPORTS and what effects these have on the present and future conditions on Earth, is one of the greatest challenges in oceanography. One of the most important aspects that preclude the full understanding of the ocean carbon cycle is the lack of parallel measurements at a global scale; this also hinders our ability to make robust predictions in an uncertain future. The EXport Processes in the Ocean from RemoTe Sensing (EXPORTS) Science Plan was proposed to NASA in order address this knowledge gap. It aims at developing a predictive understanding of the export and fate of global ocean net primary production (NPP) and its implications to the ocean carbon cycle for present and future climates. The goal of this project is to quantify of the mechanisms that control the export of carbon from the euphotic zone as well as its fate in the underlying “twilight zone”.

More than 130 geoscientists and cyberinfrastructure researchers beat the early June heat wave in Denver by spending their time planning the next stages of the National Science Foundation’s (NSF) EarthCube e-infrastructure project. Attendees of the third annual All Hands Meeting (AHM) represented major geoscience data facilities, hardware and software developers and scientists interested in the digital tools being developed. This year’s AHM marked an important milestone in the EarthCube project: as it approaches its fourth year, EarthCube cyberinfrastructure is coalescing around a number of common themes regarding the handling and sharing of data in the geosciences.

The most extensive land-based study of the effect of drought on Amazonian rainforests to date has shown that a recent drought completely shut down the Amazon Basin’s carbon sink. Previous research has suggested that the Amazon – the most extensive tropical forest on Earth – may be gradually losing its capacity to take carbon from the atmosphere. This new study paints a more complex picture, with forests responding dynamically to an increasingly variable climate.

Planting new forests could contribute more to the mitigation of climate change than previously thought, according to a new study. This is due to the combined effect of land use changes and the enhanced carbon uptake of the terrestrial biosphere in a warm and high carbon dioxide climate, according to the study’s authors.

A long-dormant volcano outside Italy’s capital is entering a new eruptive cycle, a recently published study finds. Scientists previously assumed Colli Albani, a 15-kilometer (9-mile) semicircle of hills outside Rome, was an extinct volcano. But in recent years, scientists have observed new steam vents, earthquakes and a rise in ground level in the hills and surrounding area.

The phrase “tipping point” passed its own tipping point and caught fire after author Malcolm Gladwell’s so-named 2000 book. It’s now frequently used in discussions about climate change, but what are “climate tipping points”? And what do they mean for society and the economy?

Last year, scientists made a splash with the news that dark streaks on the Martian surface were signs of flowing liquid water. So far, they have been unable to determine where the water is coming from, but a new study uses recently acquired data of a large canyon system on Mars to eliminate some of the possibilities.

Research identifies earlier ocean warming as dominant effect off West Coast.

New research into the movements of dust around Jupiter’s four largest moons could help scientists searching for life in our solar system, according to a new study. This moon dust around Jupiter could give scientists clues about the composition of the surface of its satellites.
