We have known about the perils of climate change for more than two decades. But global efforts to slow it down by reducing greenhouse-gas emissions have largely failed. Even if we could stop producing greenhouse gases tomorrow, the high concentration of carbon dioxide already in the atmosphere will cause the climate to continue to change. As a result we must not only intensify our efforts to reduce climate change but start preparing for its inevitable effects.
ADVANCE is a partnership between World Wildlife Fund (WWF) and the Columbia University Center for Climate Systems Research (CCSR) at The Earth Institute. Launched in 2015, ADVANCE facilitates planning and decision-making by providing new ways of generating and integrating climate risk information into conservation, development, and disaster management policy and practice.
The Southwest is considered to be one of the most “climate-challenged” landscapes in the United States (Garfin et al. 2013) and the Colorado Plateau will not be exempt from the impacts of a changing climate. Through the 21st century, the Colorado Plateau is projected to experience hotter temperatures, increased aridity and precipitation variability, and more severe droughts (Seager et al. 2007; Garfin et al. 2013; Cook et al. 2015). Projected climate changes will interact with existing land uses, and each species and ecosystem will respond in unique ways.
We present a landscape-scale climate change adaptation plan that characterizes climate vulnerability and provides a foundation for adaptation action on the North Rim Ranches, a 3,360-km2 (830,000-acre) landscape of significant ecological and cultural importance on the North Rim of the Grand Canyon. The extent of the North Rim Ranches is defined by the livestock grazing permits held by the Grand Canyon Trust (the Trust) for allotments on public lands managed by the North Kaibab Ranger District of the U.S.
The impact of climate change on cold-water ecosystems—and the cold-adapted native salmonids present in these systems—is the subject of a substantial body of research.. Recently, scientists have developed a number of datasets and analyses that provide insight into projections of climate change e ects on native salmonid populations in the northern U.S. Rockies region.
