Spring is coming early in 3/4 of national parks, according to a new study. Awesome? Not so much. As flowers bloom earlier every year, it’s disrupting the link between the wildflowers and the arrival of birds, bees, and butterflies that feed on and pollinate the flowers. In Shenandoah, an earlier spring is giving invasive plants a head start, and they’re displacing native wildflowers, leading to costly management issues.
Before the 1960s almost everything about living openly as a lesbian, gay, bisexual, or transgender (LGBT) person was illegal. New York City laws against homosexual activities were particularly harsh. The Stonewall Uprising on June 28, 1969 is a milestone in the quest for LGBT civil rights and provided momentum for a movement.
Vine Creek Ranch at Death Valley National Park. Steady drought and record summer heat make Death Valley a land of extremes. Towering peaks are frosted with winter snow. Rare rainstorms bring vast fields of wildflowers. Lush oases harbor tiny fish and refuge for wildlife and humans. Despite its morbid name, a great diversity of life survives in Death Valley.
Located 2,600 miles southwest of Hawaii, the National Park of American Samoa is the most remote unit of the National Park System and the U.S. National Park south of the Equator. The Park spreads across three islands, 9,500 acres of tropical rainforest, and 4,000 acres of ocean, including coral reefs. While remote, the islands of American Samoa, true to the meaning of the word Samoa (Islands of Sacred Earth), are welcoming and offer beautiful landscapes and centuries of culture and history.
DOINews: Upcoming Webinar: Climate change impacts on winter and spring hydrology in a temperate region

On Monday, April 8 at 4:00 PM ET, Evan Murdock, Nelson Institute for Environmental Studies, University of Wisconsin Madison will conduct a presentation on the "Climate change impacts on winter and spring hydrology in a temperate region".
As the scientific consensus on the reality of climate change has become near-absolute, there has grown to be considerable interest in predicting its impacts on environmental services. Of particular concern are impacts on water resources, as flooding, drought, water availability, and other water-related issues have profound impacts on people's lives and livelihoods.
Unfortunately, considerable uncertainty remains about how precipitation patterns may change in the future, limiting the ability of planners to react to these changes. Given this difficulty it is reasonable to pursue those elements of water resources that are most influenced by temperature change. In Wisconsin's temperate climate, these processes are winter snowfall, snowmelt, and soil frost formation.
The one-dimensional Simultaneous Heat and Water (SHAW) model was used to simulate two continuous 29-year periods representing historical (1970-1999) and future (2040-2069) climate conditions in southern Wisconsin, based on downscaled GCM data from the North American Regional Climate Change Assessment Program (NARCCAP).
Modeling showed that warmer winter and spring temperatures lead to a decrease in runoff and a commensurate increase in recharge. Additional modeling with the frost portion of the model disabled confirmed the importance of soil frost formation to the results. These results held across different climate models and a wide range of soil types.
