Just as growth rings can offer insight into climate changes occurring during the lifespan of a tree, corals have much to tell about changes in the ocean. At Caltech, climate scientists Jess F. Adkins and Nivedita Thiagarajan use manned submersibles, like Alvin operated by the Woods Hole Oceanographic Institution, to dive thousands of meters below the surface to collect these specimens—and to shed new light on the connection between variance in carbon dioxide (CO2) levels in the deep ocean and historical glacial cycles.
This year's commencement speaker, Pulitzer Prize-winning energy expert Daniel Yergin, came to campus a day early to get better acquainted with Caltech's faculty and students, and in particular to learn more about Caltech's energy initiatives.
Caltech researchers at the Joint Center for Artificial Photosynthesis have devised a way to protect technologically important semiconductors from corrosion even as the materials continue to absorb light efficiently.
A new $15 million gift by Lynda and Stewart Resnick in support of the Resnick Sustainability Institute at Caltech will help scientists and engineers advance research aimed at helping humanity sustainably meet its needs.
Today's Earth Week feature highlights three cross-disciplinary research centers where Caltech scientists and engineers collaborate on projects that will have a positive impact on energy, the environment, and Earth's sustainable future.
Caltech joins the world in celebrating Earth Week, April 21–25, 2014, with events, news, and features highlighting our past, present, and future contributions to a healthier, cleaner, and greener planet.
