Man-made changes bring about new epoch in Earth's history

01-25-2008 · EurekAlert!

Geologists from the University of Leicester propose that humankind has so altered the Earth that it has brought about an end to one epoch of Earth's history and marked the start of a new epoch.

  1. Scientists concerned about effects of global warming on infectious diseases
    05-22-2007 · EurekAlert!
    As the Earth’s temperatures continue to rise, we can expect a signficant change in infectious disease patterns around the globe. Just exactly what those changes will be remains unclear, but scientists agree they will not be for the good.

  2. Midges send undeniable message -- Planet is warming
    12-11-2006 · EurekAlert!
    Small insects that inhabit some of the most remote parts of the United States are sending a strong message about climate change. New research suggests that changes in midge communities in some of these areas provide additional evidence that the globe is indeed getting warmer. Researchers created a history of changing midge communities for six remote mountain lakes in the western United States.

  4. Environmental changes preceded first great rise in atmospheric oxygen
    09-27-2007 · EurekAlert!
    The history of life on Earth is closely linked to the appearance of oxygen in the atmosphere, which scientists think first occurred in significant amounts during a "Great Oxidation Event" some 2.4 billion years ago. However, until now little was known of environmental changes prior to this event. New findings indicate that significant oxidative changes were occurring in the oceans and atmosphere before the Great Oxidation Event.

  5. New evidence of the link between carbon dioxide emissions and climate change in boreal ecosystems
    02-18-2007 · EurekAlert!
    New research aimed at understanding the link between carbon dioxide emissions and climate change in boreal systems has found clear links between both spring and fall temperature changes and carbon uptake/loss. Dr. Kevin Robert Gurney, assistant professor in the Earth & Atmospheric Science/Agronomy at Purdue University and associate director of the Purdue Climate Change Research Center, presented these results at the American Association for the Advancement of Science meeting in San Francisco, Calif., on December 17.

    08-08-2007 · EurekAlert!
    Approximately 250 million years ago, vast numbers of species disappeared from Earth. This mass-extinction event may hold clues to current global carbon cycle changes, according to Jonathan Payne, assistant professor of geological and environmental sciences at Stanford University.

  7. NASA mission checks health of Greenland's ice sheet and glaciers
    05-30-2007 · EurekAlert!
    A NASA-led research team has returned from Greenland after an annual three-week mission to check the health of its glaciers and ice sheet. About 82 percent of Greenland is made up of a giant ice sheet. During the Arctic Ice Mapping Project, researchers measured critical areas of the island's ice sheet as well as its glaciers and monitored changes that may be connected to global climate change.

  8. El Niсo affected by global warming
    12-20-2007 · EurekAlert!
    A team of IRD scientists and chilean researcher made some unexpected findings about the recent evolution of the ENSO system. Investigation of marine sedimentary drill cores enabled them to retrace the changes in the ENSO's functioning since the XVIIth Century to the present. Results showed a 2°C fall in temperature of the waters of the Humboldt current system for the period 1820-1878. This time corresponds to the end of the Little Ice Age yet coincides with a warming of the Earth.

    07-31-2007 · EurekAlert!
    A leading expert today repeated his assertion that an Indonesian mud volcano was almost certainly man-made despite a new study claiming the eruption might have been triggered by an earthquake.Professor Richard Davies of Durham University's Center for Research into Earth Energy Systems, said the volcano, known locally as Lusi, was most likely caused by the drilling of a nearby exploratory borehole looking for gas.

  10. Clock comparison yields clues to 'constant' change
    02-15-2007 · EurekAlert!
    Years of comparisons among the world's best atomic clocks -- based on different atoms -- have established the most precise limits ever achieved in the laboratory for detecting possible changes in so-called 'constants' of nature. The comparisons at NIST may help scientists test the latest theories in physics and develop a more complete understanding of the history of the universe.
