The FGGE Advisory Panel under the U.S. Committee for the Global Atmospheric Research Program of the National Academy of Sciences has recently published a document that describes the observational systems and availability of research data for the Global Weather Experiment (FGGE). In addition, many areas of research using the FGGE global data sets are suggested by scientists who participated in several FGGE workshops during late 1975 and early 1976. A summary of the document follows.

<p>The American Geosciences Institute in cooperation with its member societies has developed the Framework for Addressing Racial and Ethnic Equity in Geosciences Professional Societies.  The geoscience societies are a pivotal area to influence the culture of the geosciences, and in response to the events of June 2020, many societies determined they needed to directly act on the issue of equity in the geosciences. Being birthed from a federation of US-centric organizations, the Framework has clear US-aligned approaches and boundaries.  However, the baseline proposed actions are fundamentally universal and meet the goal of the authoring committee to provide a framework from which we hope geoscience organizations of all types would use it to craft their own specific action plan and policies.   A critical component of this framework for the committee was to ensure definable actions were included.   Some of these suggested actions and their intended extensions will be discussed.  Additionally, ongoing conversations among the societies, with the US National Academy of Sciences Board on Earth Science and Resources, and other science organizations have begun to examine what the path forward looks like.   One area that AGI particularly is concerned about is the process of measuring progress.   Understanding and recognizing the impacts of efforts like this is critical to ensure agile responses for success.   But with AGI's intimate knowledge of much of the U.S. federal data, some of the ambiguities and definitional challenges within the US system complicates the ability to directly measure progress and for which further discussion of what success looks like is critically needed.  </p>

David Sandwell developed this advanced textbook over a period of nearly 30 years for his graduate course at Scripps Institution of Oceanography. The book augments the classic textbook Geodynamics by Don Turcotte and Jerry Schubert, presenting more complex and foundational mathematical methods and approaches to geodynamics. The main new tool developed in the book is the multi-dimensional Fourier transform for solving linear partial differential equations. The book comprises nineteen chapters, including: the latest global data sets; quantitative plate tectonics; plate driving forces associated with lithospheric heat transfer and subduction; the physics of the earthquake cycle; postglacial rebound; and six chapters on gravity field development and interpretation. Each chapter has a set of student exercises that make use of the higher-level mathematical and numerical methods developed in the book. Solutions to the exercises are available online for course instructors, on request.

Land degradation neutrality (LDN) is defined as a "state whereby the amount and quality of land resources nec-essary to support ecosystem functions and services and enhance food security remain stable or increase within specified temporal and spatial scales and ecosystems". The baseline is expressed as the initial (t0) estimated value of each of the three indicators, used as proxies of land-based natural capital and the ecosystem services that flow from that land base: land cover/land use change, land productivity status and trends, soil organic carbon status and trends. The baseline of LDN was calculated with estimation of the average values across the 10 years baseline period of the following indica-tors: Land Cover/Land Cover change (LC/LCC), Land Productivity Dynamics (LPD) and Soil Organic Carbon (SOC). Three tier approaches for computation of the selected indicators were used: Tier 1: Global/regional Earth observation, geospatial information and modelling; Tier 2: National statistics (only for LC/LCC) and Tier 3: Field survey. Most sig-nificant changes in LC for the period 2000/2012 are in the categories of Forest land and Shrubs/grasslands. According the global data sets used for analysis of LPD, the total affected area with depletion of Land productivity for the period 2000/2010 is identified on a only 2.35 % of the country territory. The available global data sets gives a model SOC lev-els for the period 2000/2010. According these data, the total loss of SOC in our country is estimated on 3951 t.

The National Academy of Sciences convened in 1995 for a conference on massive data sets. The presentation on health care noted that “massive applies in several dimensions . . . the data themselves are massive, both in terms of the number of observations and also in terms of the variables . . . there are tens of thousands of indicator variables coded for each patient” (Goodall, 1995, paragraph 18). We multiply this by the number of patients in the United States, which is hundreds of millions.
