Venus may have had a shallow liquid-water ocean and habitable surface temperatures for up to 2 billion years of its early history, according to computer modeling of the planet’s ancient climate by scientists at NASA’s Goddard Institute for Space Studies (GISS) in New York.

The first peer-reviewed study to directly quantify how emissions from oil and gas activities influence summertime ozone pollution in the Colorado Front Range confirms that chemical vapors from oil and gas activities are a significant contributor to the region’s chronic ozone problem.

The Geoscience Papers of the Future: a modern publication strategy for data management and scientific publication
Many data used in scientific papers are not accessible by reading the papers, which makes it difficult to understand and reuse. To effectively communicate data results and preserve observations, simulations, and predictions, the Geoscience Papers of the Future was launched in 2015.
Earlier snowmelt periods associated with a warming climate may hinder subalpine forest regulation of atmospheric carbon dioxide.

NASA researchers have helped produce the first map showing what parts of the bottom of the massive Greenland Ice Sheet are thawed – key information in better predicting how the ice sheet will react to a warming climate. Knowing whether Greenland’s ice lies on wet, slippery ground or is anchored to dry, frozen bedrock is essential for predicting how this ice will flow in the future, but scientists have very few direct observations of the thermal conditions beneath the ice sheet.

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.
