Lithium isotopes are a relatively novel tracer of present and past silicate weathering processes. Given that silicate weathering is the primary long-term method by which CO2 is removed from the atmosphere, Li isotope research is going through an exciting phase. We show the weathering processes that fractionate dissolved and sedimentary Li isotope ratios, focusing on weathering intensity and clay formation. We then discuss the carbonate and silicate archive potential of past seawater δ7Li. These archives have been used to examine Li isotope changes across both short and long timescales. The former can demonstrate the rates at which the climate is stabilised from perturbations via weathering, a fundamental piece of the puzzle of the long-term carbon cycle.

"In the beginning of the twentieth century, the Connecticut River Valley was a thriving manufacturing hub for fabric, arms and brass. But early in the spring of 1936, nearly two feet of rain created havoc on a massive scale, killing more than one hundred people and leaving tens of thousands homeless, unemployed and without power for weeks. Patrols were conducted in rowboats on city streets. Typhoid and other public health issues complicated recovery efforts. Adjusted for today's standard, damage estimates exceeded $9 billion, and the flood helped launch FDR's Flood Control Act of 1936. Dams, reservoirs and dikes were constructed to control future flooding. Much of that system now remains in place but has gone largely unmaintained. Author Josh Shanley recounts the greatest flood in New England history and examines the potential for future floods"--Back cover
