Our Purpose Remains Constant: To deploy, fight and win our nation’s wars by providing ready, prompt and sustained land dominance by Army forces across the full spectrum of conflict as part of the joint force. The Army mission is vital to the Nation because we are the service capable of defeating enemy ground forces and indefinitely seizing and controlling those things an adversary prizes most – its land, its resources and its population.

Central Appalachia Prosperity Project
-
The Central Appalachia Prosperity Project is part of the Presidential Climate Action Project to develop policy recommendations on climate and energy security, with a focus on what the next President of the United States could accomplish using his or her executive authority. The Central Appalachian Project draws on the input of America's most innovative experts to produce policy and program recommendations that are sufficiently bold to expedite the region's transition to a clean energy economy. An important component of these recommendations has been better coordination of the efforts being made by all levels of government - federal, regional, state and local.

Formation of soil organic matter via biochemical and physical pathways of litter mass loss
-
Soil organic matter is the largest terrestrial carbon pool (1). The pool size depends on the balance between formation of soil organic matter from decomposition of plant litter and its mineralization to inorganic carbon. Knowledge of soil organic matter formation remains limited (2) and current C numerical models assume that stable soil organic matter is formed primarily from recalcitrant plant litter (3) . However, labile components of plant litter could also form mineral-stabilized soil organic matter (4). Here we followed the decomposition of isotopically labelled above-ground litter and its incorporation into soil organic matter over three years in a grassland in Kansas, USA, and used laboratory incubations to determine the decay rates and pool structure of litter-derived organic matter. Early in decomposition, soil organic matter formed when non-structural compounds were lost from litter. Soil organic matter also formed at the end of decomposition, when both non-structural and structural compounds were lost at similar rates. We conclude that two pathways yield soil organic matter efficiently. A dissolved organic matter–microbial path occurs early in decomposition when litter loses mostly non-structural compounds, which are incorporated into microbial biomass at high rates, resulting in efficient soil organic matter formation. An equally efficient physical-transfer path occurs when litter fragments move into soil.

Novel climates, no-analog communities, and ecological surprises
-
No-analog communities (communities that are compositionally unlike any found today) occurred frequently in the past and will develop in the greenhouse world of the future. The well documented no-analog plant communities of late-glacial North America are closely linked to “novel” climates also lacking modern analogs, characterized by high seasonality of temperature. In climate simulations for the Intergovernmental Panel on Climate Change A2 and B1 emission scenarios, novel climates arise by 2100 AD, primarily in tropical and subtropical regions. These future novel climates are warmer than any present climates globally, with spatially variable shifts in precipitation, and increase the risk of species reshuffling into future no-analog communities and other ecological surprises. Most ecological models are at least partially parameterized from modern observations and so may fail to accurately predict ecological responses to these novel climates. There is an urgent need to test the robustness of ecological models to climate conditions outside modern experience.
