Eastern European Tree Rings Reveal Climate Variability and Human History

Adding to the growing evidence that ‘things are not as they once were’, a new dendrochronological study has found that socio-cultural disruptions in Eastern Europe during the past millennium coincided with periods of decreased temperature, and recent temperature in the region is warmer than at any previous time over the past thousand years. Oh, dendrochronological is the […]

Pollen and Charcoal Document Ancient Egypt's Climate History

Researchers from the U.S. Geological Survey studying ancient pollen and charcoal preserved in deeply buried sediments in Egypt’s Nile Delta have documented the region’s ancient droughts and fires, including a massive drought that happened approximately 4,200 years ago and is thought to have seen the demise of Egypt’s Old Kingdom. “Humans have a long history

Link Found Between Ancient Climate Change and Mass Extinction

New research led by researchers at the California Institute of Technology, Caltech, have discovered new details that support the idea that the mass extinction that took place approximately 450 million years ago, known as the Late Ordovician mass extinction, was linked to a cooling climate. During the Late Ordovician mass extinction more than 75 percent

Scientists Create Climate Time Machine

  The 20th Century Reanalysis Project (20CR), a joint project between the National Oceanic and Atmospheric Administration and the University of Colorado, has brought together 27 international climatologists to create a comprehensive reanalysis of all global weather events from 1871 to present day, effectively creating an accessible time machine for climate scientists. The project allows

Is Our Hot Past Representative of Our Future

An analysis by National Center for Atmospheric Research (NCAR) scientist Jeffrey Kiehl published in the most recent edition of the journal Science in the ‘Perspectives’ section has concluded that the sheer scale of climate change during Earth’s ancient history points to temperatures rising far more than expected in Earth’s immediate future. Kiehl brought together several

Oxygen-Free Oceans Wrought Changes on Early Earth

Geologists at the University of California, Riverside, have discovered chemical evidence that indicates Earth’s ancient oceans were not only oxygen-free, but also contained large quantities of hydrogen sulphide in some areas. “We are the first to show that ample hydrogen sulfide in the ocean was possible this early in Earth’s history,” said Timothy Lyons, a

Mammal Extinctions Linked to Climate Footprints

The mass extinction of mammal species 50,000 years ago possibly linked to continental climate footprints. [social_buttons]An international team of scientists used global data modelling to construct continental “climate footprints” in an effort to determine the cause of the mass extinctions that took place 50,000 years ago. “Between 50,000 and 3,000 years before present (BP) 65%
