    Climate Change and the Future of Mono Lake

    Understanding the climate history of Mono Lake will help scientists understand the future impact of climate change. This is no esoteric question for Los Angeles, which depends in part on Mono Lake’s watershed for drinking water, green lawns, agriculture and industry.

    Q&A: Climate Change, Drought and the Future

    “One of the ways that climate change is going to manifest is through warmer temperatures. … What we are seeing, in line with our projections, is that even if you assume constant precipitation, the temperature effects are so large that it is going to dry things out. This is going to have really big impacts…

    Tensiometers in Punjab

    So far, tensiometers have been tested in four central districts of Punjab, initially with more than 500 farmers the first year, and then peaking with an additional 4,500 farmers in 2011 before testing was scaled back. Data showed, on average, a 30 percent reduction in the water used in the test plots when compared with…

    Preparing for Chimborazo

    I am staying with a friend’s family in Quito, Ecuador’s capital city, and tomorrow will meet up with my climbing partner, Pablo Puruncajas, to prepare for our expedition. I am here to collect tree ring samples and put up a weather station on Chimborazo, Ecuador’s tallest peak, to provide climate data about this region, which…
