The Caribbean Climate Sub Hub (CCSH) is located in Río Piedras, Puerto Rico, and is one of seven Regional Hubs and three Subsidiary Hubs nationwide. The CCSH will work with USDA to deliver science based knowledge and practical information to farmers, ranchers, and forest landowners that will help them to adapt to climate change and weather variability by coordinating with local and regional partners in federal and state agencies, universities, and the public. The CCSH is focused on tropical forestry and agriculture and will provide:
Technical support for agricultural land and forest managers to respond to drought, heat stress, floods, pests, and changes in growing season in Puerto Rico and the U.S. Virgin Islands.
Outreach and education to farmers, ranchers, forest managers and advisors on ways to build resilience to extreme weather events and thrive despite change.
The Vision of the CCSH is that agencies, organizations, producers, managers, and decision-makers work collaboratively to promote sustainable and best management practices that ensure food, water, and other vital resources are available in the US Caribbean by sustaining and strengthening the services provided by natural land and seascapes, working lands and rural communities in the face of changing climate. The Mission of the CCSH is to help society sustain and improve the viability of forestry and agricultural production, the availability and quality of soil and water resources, the viability and quality of rural lifestyles, and food security in light of climate variability and change. The Goal of the CCSH is to develop and deliver information related to climate, agriculture, and forestry for better planning and implementation of actions related to the mitigation of and adaptation to climate change in the tropical working lands and oceans in the Caribbean.
Rising sea levels are being caused by a change in the volume of the world's oceans due to temperature increase, deglaciation (uncovering of glaciated land because of melting of the glacier), and ice melt. This data viewer can provide a preliminary look at sea level rise and how it might affect coastal resources across the United States (with the exception of Alaska and Louisiana). Data and maps can be used at several scales to help gauge trends and prioritize actions for different scenarios.

Water stress represents a common mechanism for many of the primary disturbances affecting forests, and forest management needs to explicitly address the very large physiological demands that vegetation has for water. This study demonstrates how state-of-science ecohydrologic models can be used to explore how different management strategies might improve forest health.
Widespread threats to forests due to drought stress prompt re-thinking of priorities for water management on forest lands. In contrast to the widely held view that forest management should emphasize providing water for downstream uses, we argue that maintaining forest health in the face of environmental change may require focusing on the forests themselves and strategies to reduce their vulnerability to increasing water stress in the context of a changing climate. Management strategies would need to be tailored to specific landscapes but could include: a) thinning; 2) encouraging drought-tolerant species; 3) irrigation; and 4) strategies that make more water available to plants for transpiration. Hydrologic modeling reveals that specific management actions could reduce tree mortality due to drought stress. Adopting water conservation for vegetation as a priority for managing water on forest lands would represent a fundamental change in perspective and potentially involve tradeoffs with other downstream uses of water.
This application from NASA provides datasets and a viewer for geographic data that support large-scale carbon inventory. The datasets combine NASA remote sensing technology, ecosystem process modeling, and field-based measurements to characterize impacts on the carbon cycle.
The CASA Global CQUEST application provides datasets and a geographical data viewer that support large-scale carbon inventory. Users can display global data on net primary productivity, net ecosystem productivity, and other variables interactively as a map and obtain data values in tabular format.
Data Basin is a science-based mapping and analysis platform that supports learning, research, and sustainable environmental stewardship. The Climate Center is powered by Data Basin, and centralizes climate change-related datasets, maps and findings. Tools are provided to visualize, analyze, and communicate vulnerabilities, trends or predicted future scenarios at local and regional scales.
The Data Basin Climate Center centralizes climate change-related datasets, maps and findings. Tools are provided to visualize, analyze, and communicate vulnerabilities, trends or predicted future scenarios at multiple scales.
The SAVS uses an online questionnaire with 22 criteria to predict vulnerability or population response of species to provide a framework for assessing vulnerability to future climate change. The 22 multiple-choice questions are grouped into four categories by theme: habitat, physiology, phenology and biotic interactions. The questionnaire is completed using information gathered from published materials, personal knowledge, or expert consultation.
SAVS uses an online questionnaire with 22 criteria to predict vulnerability or resilience of an individual species to future climate change. Numerical scores indicating vulnerability or resilience for terrestrial vertebrate species are generated.
