CNN —Scientists have voted against a proposal to declare a new geological epoch called the Anthropocene to reflect how profoundly human activity has altered the planet. The vote followed a 15-year process to select a geological site that best captures humanity’s impact on the planet. Some experts argued that the start of the Anthropocene could be better defined in other ways, such as the beginning of the Industrial Revolution. “This is the commission’s expert group for this interval of geological time and we are bound by its decision. Regardless of whether the term is officially classified as a geological epoch, Anthropocene is already widely in use, Cohen noted.

CNN —Scientists have identified the geological site that they say best reflects a proposed new epoch called the Anthropocene — a major step toward changing the official timeline of Earth’s history. “We’ve moved into this new Earth state and that should be defined by a new geological epoch,” Waters added. On Tuesday, the scientists announced the geological site — Crawford Lake in Ontario, Canada — that best captures the geological impact of the Anthropocene, according to their research. Annual sediment samples from the Crawford Lake site have revealed geochemical traces of nuclear bomb testing, researchers have confirmed. The alpha spectrometry output shown on the screen indicates the presence of plutonium in a Crawford Lake drill core sample.

CNN —Everywhere you look on Santorini, you’re reminded that you’re on a volcano. Few realize that beneath the hypnotic kaleidoscope of colors lies an active volcano. The East Mediterranean’s most active underwater, and potentially dangerous, volcano, Kolumbo, is five miles northeast of Santorini and part of the same volcanic system. They include a visit to the volcano of Nea Kameni: one of five islands that form the Santorini volcanic complex, and a national geological park in itself. A simmering volcanoTourists can take boat trips to Nea Kameni, home to an active volcano.
