Maar lake sediments reveal a grand solar minimum and the climate response recorded for the first time in the same climate archive highlights the need for a more differentiated approach to solar radiation.
Both observational and proxy records of climate change often show quasi periodic variations similar to solar activity cycles over a wide range of time scales. However, the detailed mechanism and the extent of the influence of solar ... Read Post
Climate signals locked in the layers of glacial ice, preserved in the annual growth rings of trees, or fingerprinted in other so-called proxy archives such as lake sediments, speleothems, and corals allow researchers to quantify cli... Read Post
One of the oldest lakes in the world, Clear Lake in northern California has deep sediments that contain a record of the climate and local plants and animals going back perhaps 500,000 years. Scientists are drilling cores from the se... Read Post
