Building upon a legacy of coastal science at Scripps, high-tech tools are opening new avenues for researchers to track sand movements and further explain beach systems.
A thick chunk of Arctic sea ice the size of two states has disappeared. Is it global warming or normal causes? For more information visit: http://www.jpl.nasa.gov/videos/earth/earth20071001/
Coral reefs are dying a death of a thousand cuts and their disappearance threatens not only the incredibly diverse ecosystem that depends on them, but also human health and welfare. In this episode of MicrobeWorld Video marine scientists Ove Hoegh-Guldberg, Ph.D., chair of marine studies at the University of Queensland in Brisbane, Australia, and Kiho Kim, Ph.D., director of the environmental studies program at American University, explain the important relationship between microbes and corals, and how this delicate symbiosis that sustains life on and around reefs is facing numerous threats from human interactions to global climate change. In addition, Tundi Agardy, Ph.D., founder and executive director of Sound Seas, discusses the need for public policy and community-based conservation efforts that may help stave off the degradation of these vital ocean ecosystems. According to a 2004 report issued by the World Wildlife Fund, 24% of the world's reefs are under imminent risk of collapse through human pressures; and a further 26% are under a longer term threat of collapse. If nothing is done to protect these resources, many scientists estimate that reefs around the West Indies in the Caribbean will be gone by 2020, while the Great Barrier Reef may only last for another three decades.

Fifty years after Sputnik, satellites peering down on Earth have become valuable scientific tools to study the global environment and offer much needed insight into the future of our planet.
Emperor penguins can flourish in locales where few other animals roam. But scientists now wonder if they can adapt to a new threat: climate change.
Regularly spaced clouds appear in Jupiter's belts, sometimes white spots and sometimes swirling waves. A polar projection of Jupiter, made by NASA from the 2000 flyby, allows accurate testing of the hypothesis that these waves form as predicted by the Harmonics Theory. It is found that expected strong harmonics 12, 24 and 72 are present.
An ancient global warming episode drastically changed the planet. Life on Earth needed 200,000 years to recover. What we're headed for in the next century could be even bigger.
Deciphering the secrets of past climate hidden in ice cores depends on the technical skills and ingenuity under pressure of drillers from ICDS, the University of Wisconsin-Madison's Ice Coring and Drilling Services. In this video, ICDS staffers Lou, Mike and Jay explain why they enjoy the life of drillers, braving extreme cold in some of the remotest regions of the globe. Mike says drilling requires both science and art, and why he keeps his hand on the cable even when it's minus 20; Lou talks about feeling connected to the equipment in order to keep it running properly, and Jay explains the satisfaction of having fun amidst beautiful scenery, and helping obtain good data for the researchers.
The inception of the "Keeling Curve," a history of atmospheric carbon dioxide levels, marked a key moment in American science history. The record began in March, 1958 at a small observatory on the top of Hawaii's Mauna Loa.
Research News from Iowa State University's College of Agriculture and Life Sciences. Lisa Schulte, Iowa State University Landscape Ecologist, discusses her latest publication Homogenization of northern U.S. Great Lakes forests due to land use.
A network devoted to recording the state of the oceans is nearing its full complement. Will it remain intact as its decades-long mission begins?
After two decades watching atmospheric oxygen levels drop, a Scripps researcher's conclusions about climate could leave one feeling light-headed.
Resonance is the quality of transmitting even tiny signals between systems that are tuned to the same frequency. Given that cycles of common period are found pervading many different disciplines, perhaps an explanation may be found in resonance. An example is the 160 minute (and associated 80 minute cycle) cycle, found in biological systems, outer planetary spacings, the rotation rates of planets, asteroids and binary stars, solar oscillation and flux and galactic cores. A cosmic pervading vibration is the most likely cause, but this is not even considered in conventional cosmology.
The historic city of Venice, Italy is sinking. City leaders have called upon Scripps and a multifaceted team of experts to help decipher the mysteries lying beneath its waters and save the city.

Imagine what Earth would be like if we had to endure storms like those on neighboring planets
Solar storms have the potential to devastate our planet.
How to improve technology to better predict severe weather events. Originally posted by SDSC on SDSC's CI Channel at: www.cichannel.org. Transforming the Sensing and Numerical Prediction of High Impact Local Weather Through Dynamic Adaptation By Kelvin Droegemeier
Basic ideas of geophysical wave motion in rotating, stratified, and rotating-stratified fluids. Subject begins with general wave concepts of phase and group velocity. The dynamics and kinematics of gravity waves with a focus on dispersion, energy flux, initial value problems, etc. Subject foundation used to study internal and inertial waves, Kelvin, Poincare, and Rossby waves in homogeneous and stratified fluids. Laplace tidal equations are applied to equatorial waves. Other topics include: resonant interactions, potential vorticity, wave-mean flow interactions, and instability.
