Greenland wasn’t always covered in ice. In fact, within the last 1.1 million years ,Greenland had thriving vegetation and ecosystems. That is the conclusion of an international group of researchers including a scientist from Lawrence Livermore National Laboratory (LLNL) that analyzed sediment at the base of the Camp Century ice core (1.4 kilometers deep) collected in 1966. The research appears in the Proceedings of the National Academy of Sciences.

George Peridas, director of carbon management partnerships, and staff scientist Briana Schmidt from Lawrence Livermore National Laboratory, will be available to discuss results from a new report titled “Permitting Carbon Capture and Storage in California” that examined the regulatory framework for authorizing carbon capture and storage in California and offers options for government and project developers to enable robust, transparent and efficient project permitting in line with the state’s goal to reach carbon neutrality by 2045 or earlier.
To reach economy-wide carbon-neutrality by 2045 or earlier, California will likely have to capture, transport and geologically store tens of millions of tons per year of carbon dioxide (CO2) from large sources and from the atmosphere. California has an extensive regulatory framework that is rigorous, robust and will safeguard the environment, public health and safety during these activities. However, this framework cannot handle the timely permitting and deployment of sufficient projects to protect the rapidly worsening climate and support achieving the state’s climate goals, according to a report by Lawrence Livermore National Laboratory (LLNL).
In recent research published in the Proceedings of the National Academy of Sciences, Lawrence Livermore National Laboratory (LLNL) researchers Babak Sadigh, Luis Zepeda-Ruiz and Jon Belof report on a new mechanism of solidification in copper that provides an atomistic view of Ostwald’s step rule and alters the fundamental understanding of nucleation at high pressure. They found that not only does the crystallization process proceed via a non-equilibrium phase, but that this phase can be kinetically stabilized by the temperature.

Decades of studies have shown that carbon’s crystal structure has a significant impact on material properties. In addition to graphite and diamond, the most common carbon structures found at ambient pressures, scientists have predicted several new structures of carbon that could be found above 1,000 gigapascals (GPa). These pressures, approximately 2.5 times the pressure in Earth’s core, are relevant for modeling exoplanet interiors but have historically been impossible to achieve in the laboratory. That is, until now. Under the Discovery Science program, which allows academic scientists access to Lawrence Livermore National Laboratory’s (LLNL) flagship National Ignition Facility (NIF), an international team of researchers led by LLNL and the University of Oxford has successfully measured carbon at pressures reaching 2,000 GPa (5 times the pressure in Earth’s core), nearly doubling the maximum pressure at which a crystal structure has ever been directly probed.

The results are relevant to the conditions at the cores of giant planets, the interiors of brown dwarfs (failed stars), the carbon envelopes of white dwarf stars and many applied science programs at LLNL. According to the authors, the overlap with white dwarf envelopes is particularly significant – this new research enables experimental benchmarks of the basic properties of matter in this regime. The results should ultimately lead to improved models of white dwarfs, which represent the final stage of evolution for most stars in the universe.
Massive compressive shearing forces generated by the tidal pull of Jupiter-like planets on their rocky ice-covered moons may form a natural reactor that drives simple amino acids to polymerize into larger compounds.

The most advanced and comprehensive analysis of climate sensitivity undertaken has revealed with more confidence than ever how sensitive the Earth’s climate is to carbon dioxide. This new research finds that the true climate sensitivity is unlikely to be in the lowest part of the 2.7-8.1˚F range. The analysis indicates that if atmospheric carbon dioxide levels double from their pre-industrial levels and are maintained, the world would be likely to experience eventual warming from 4.1-8.1˚F. There would be less than 5 percent chance of staying below 3.6˚F and a 6-18 percent chance of exceeding 8.1˚F.
