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 in the Northeastern U.S.

The NE CSC invites you to a webinar on Monday, March 11, 2013 at 4:00 PM Eastern titled "Climate Change in the Northeastern U.S.: Regional Climate Model Validation and Climate Change Projections". The webinar is being presented by the NE CSC host institution, the University of Massachusetts, Amherst.
A high resolution regional climate model (RCM) is used to simulate climate of the recent past and to project future climate change across the northeastern US. Empirical Orthogonal Functions (EOF) analysis and K-means clustering analysis are applied to divide the northeastern US region into four climatologically different zones based on the surface air temperature and precipitation variability. The RCM simulations tend to overestimate surface air temperature, especially over the northern part of the domain in winter and over the western part in summer. The RCM simulation driven by the quasi-observed boundary data shows better capabilities than the simulations driven by the GCM in reproducing the mean and variability of temperature and precipitation.
Statistically significant increase in surface air temperature under both higher and lower emissions scenarios over the whole RCM domain suggests the robustness in the future warming. Most parts of the northeastern US region will experience increasing winter precipitation and decreasing summer precipitation, but the magnitudes are insignificant. Greater magnitude of the projected temperature increase by the end of the twenty-first century under the higher emissions scenario emphasizes the essential role of emissions choices in determining the potential future climate change.
