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.

Check out the upcoming webinars in the 2014 Southwest Climate Science Center Webinar Series! This series will focus on extreme events in the Southwestern U.S.
Climate Change and Fire Regimes in the Southwest
MARCH 27; 12pm Mountain
Speaker: Julio Betancourt - U.S. Geological Survey
In the Sierra Nevada, the position of the North Pacific Jet (NPJ) strongly modulates winter hydroclimatology and, therefore, affects both tree growth and fire activity. However, there is some evidence that greater greenhouse gas-driven warming at high northern latitudes weakens the equator-to-pole temperature gradient, yielding so-called Arctic amplification and more extreme weather by altering the orientation of the NPJ. Over the last decade, the polar jet stream – the fast-flowing, high-altitude westerly air current that flows over mid and high latitudes - has experienced more north-south oriented trajectories and slower progressions, consistent with Arctic amplification. In this webinar, Dr. Julio Betancourt will discuss recent research, which uses tree-ring data from 1409 – 1990 to reconstruct how the NPJ influences tree growth and fire activity in the Sierra Nevada.
