Climate Change Visitor Experience Yosemite National Park о Climate change may widen some windows of opportunity while narrowing others, recalibrating the timetable of outdoor adventure. the park currently experiences around 14 days of 90°f plus temperatures a year; this may double by 2050 and approach 50 days by 2100. long stretches of hot weather may pose new challenges for strenuous hiking. Without a major reduction in global greenhouse gas emissions, scientists project the following trends in yosemite’s climate over the next century: faster warming: average temperatures in the park may rise by 6.7–10.3°f between 2000 and 2100. more hot days: days per year with temperatures above 90°f may quadruple from around 12 in 2016 to.
Climate Change Visitor Experience Yosemite National Park о Understanding environmental change is the first step in responding to it. for over 100 years, park staff and other researchers have monitored climate, water, snow, and ecosystems in yosemite, providing valuable information that allows us to document and communicate ongoing shifts. snow surveys have been ongoing at several sites in the park. Thundering waterfalls are iconic signs of spring in yosemite, usually reaching peak flow in late spring like 3,000 foot clockwork. they may also become one of the park’s most visible signs of change. yosemite falls, like many streams and waterfalls in the park, is fed almost entirely by snowmelt. waterfall flow is largely determined by how. Snowpack matters: tree ring analysis in yosemite shows that high mortality is triggered by multi year periods of low spring snowpack and corresponding high drought conditions. disappearing giants: between the 1930s and 1990s, the density of large diameter trees in yosemite declined by 24%. the researchers attribute this change to water stress. How your support helps: one of the most direct and visual impacts of climate change in yosemite is the disappearance of year round snow and ice features. although the park’s two glaciers have been studied extensively for more than a century, much less is known about the current state of perennial snow and ice patches in the park. a previous.

Nps glacier national park. in the past 50 years, some of the montana park’s 26 glaciers have lost as much as 80% of their area. loss of glacier ice is a huge threat for aquatic ecosystems within. For more than 100 years, yosemite conservancy has been supporting the conservation of yosemite’s natural resources and helping people develop deep ties to the park. thanks to generous donors, in recent years, we have provided more than $162 million in grants to yosemite for more than 850 projects, and more than $200 million in overall support.
