A Multi-scale Analysis of the Potential Impacts of Rapid Climate Change on Forest Lands Managed by the Department of Defense in the US
Based on current projections from global climate models (GCM's), regional climates in the coterminous U.S. are expected to become warmer and either wetter or drier over the next century depending on the GCM used to make projections. Forest communities and the species that comprise them are likely …

Media Narratives and the Weathering of Climate
The International Panel on Climate Change (IPCC) published five assessments since 1990 warning of the impact of human activity on rapid climate change. The assessments affirm that climate change will increase the frequency and severity of extreme weather events. While there is a scientifically …

Climate change at the Pleistocene-Holocene boundary in the Pacific Northwest: a comparison of proxy datasets and the archaeologicial record
<p>"The relationship between climate change at the Pleistocene-Holocene Boundary (ca. 12,600-10,200 cal B.P.) and cultural responses to attendant shifts in the environment remains a vexing issue for archaeologists. This study compiles and analyzes glacial, palynological, faunal, and …

Crustacea Zooplankton Communities in Icelandic Lakes Comparison Over Time
… regions is particularly important given ongoing rapid climate change. Communities were compared using data from two national surveys: the Ecological Survey of Icelandic Lakes (1992–1998) and the Natura Project (2012–2013). Multivariate statistical analyses were applied to assess temporal changes …

A COOPERATIVE SPACE STRATEGY FOR THE ARCTIC: POLICY, STRATEGY AND OPERATIONAL ASPECTS OF POLAR GREAT POWER COMPETITION
… of polar great power competition, coupled with rapid climate change, has drastically altered the strategic demand for space capabilities within the region. This thesis explored how the United States might benefit from a cooperative space strategy for the Arctic and whether the United States must …

Lakes in the far north of Ontario: regional comparisons and contrasts
… for other future industrial developments and rapid climate change in the north, there is a great need for basic limnological data for lakes in the Far North of Ontario. To address this need, water chemistry and crustacean zooplankton surveys of northern Ontario lakes were conducted to examine …

MISSION 2066 : a national park for the Antrhopocene
… that American protected lands are experiencing rapid climate change well above the national average, the National Park Service releases Mission 2066. The master plan acts as a critical foil to its centennial predecessor, Mission 66, which introduced a modernized highway system and architecture …

Projected Range Shift of the Atlantic Surfclam, Spisula solidissima, and the Ocean Quahog, Arctica islandica, Under Climate-Induced Benthic Warming: Forecasting Fishery Influence in the Mid-Atlantic Bight Throughout the 21st Century
… of $53.6 million in ex-vessel revenue per year. Rapid climate change is expected to modify the geographic range of these bivalve populations across the Mid-Atlantic Bight (MAB), suggesting transformative consequences for the surfclam fishery. This study forecasted future distributions of the two …

The distribution and population structure of Aloe pillansii in South Africa, in relation to climate and elevation
… namely the succulent Karoo. Anthropogenic climate change predictions for South Africa suggest rapid climate change in the next 50 years will have adverse effects on its vegetation biomes. This study shows how the aborescent succulent, Aloe pillansii, has a limited distribution due …

Evolutionary impacts of assisted gene flow: Fitness consequences of hybridization along a geo-climatic gradient in an annual prairie legume
Rapid climate change, alongside substantial habitat fragmentation, presents new challenges for biodiversity conservation in the tallgrass prairie. Therefore, capacity for adaptation in situ will be necessary for long-term population persistence. Populations with larger genetic variation likely have …

Not Too Hot, Not Too Cold, But Moderately Variable: The Influence of Environmental Variability on Coral Thermal Tolerance
<p>Anthropogenic climate change is causing an increase in the frequency and severity of marine heat waves, resulting in declining health of coral reef ecosystems worldwide. Coral bleaching events – the breakdown in symbiosis between the coral host and their intracellular photosynthetic algae – are …

Aerosol processes in polar regions : from formation to climatic implications
… affect our health, air quality, visibility and climate. They can impact the climate trough their ability to interact with radiation and to alter cloud properties by acting as cloud condensation nuclei (CCN) or ice nuclei (IN). Globally, aerosols cool the climate, but locally their effect may be …

Neanderthal and Modern Human Adaptations to Climate Change in Southwest Asia: Climate Reconstruction of Marine Isotope Stage 5 to 3 based on small mammal records from Shanidar Cave (Iraqi Kurdistan)
… environmental and climatic fluctuations and changes in hominin populations and their distribution is one of the major challenges facing archaeologists and palaeoanthropologists. One notable key demographic event is the expansion of Homo sapiens (‘Modern Humans’) and the extinction of …

Benthic environmental responses to climatic changes during the late Quaternary: a micropalaeontological and geochemical approach
… within upwelling regions responded to past rapid climatic changes. Within this thesis, a multiproxy approach is applied to two marine sediment cores from two coastal upwelling sites in the low latitude subtropical Atlantic. With a focus on benthic foraminiferal faunal analyses, the response …

Characterization of a minimal abiotic stress-inducible promoter in the development of a binary vector for crop protection
In an era of rapid climate change, increasing population pressure and declining arable land necessitate urgent agricultural adaptation. The global population is expected to reach approximately 9.3 billion people by 2050, creating pressure to increase food production by up to 60 % within the same …
