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.

  1. First-ever study to link increased mortality specifically to carbon dioxide emissions
    01-03-2008 · EurekAlert!
    A Stanford scientist has spelled out for the first time the direct links between increased levels of carbon dioxide in the atmosphere and increases in human mortality, using a state-of-the-art computer model of the atmosphere incorporating scores of physical and chemical environmental processes. The new findings, to be published in Geophysical Research Letters, come to light just after the Environmental Protection Agency's recent ruling against states setting specific emission standards for this greenhouse gas.

  2. Wildfire drives carbon levels in northern forests
    10-31-2007 · EurekAlert!
    Far removed from streams of gas-thirsty cars and pollution-belching factories lies another key player in global climate change. Circling the northern hemisphere, the conifer-dominated boreal forests -- one of the largest ecosystems on earth -- act as a vast natural regulator of atmospheric carbon levels.

  3. Climate change affecting Earth's outermost atmosphere
    12-11-2006 · EurekAlert!
    Carbon dioxide emissions from the burning of fossil fuels will produce a three percent reduction in the density of Earth's outermost atmosphere by 2017, scientists predict. Recent observations have shown that the thermosphere, which begins about 60 miles above Earth and extends up to 400 miles, is becoming less dense.

    Insects will feast and leafy plants will suffer if temperatures warm and atmospheric carbon dioxide increases, according to a team of researchers who studied evidence of insect feeding on fossil leaves from before, during and after the Paleocene-Eocene Thermal Maximum.

  5. Researchers predict future of federal climate change policy
    02-01-2007 · EurekAlert!
    The future of federal climate change policy is likely to include a host of strategies such as a national cap on carbon dioxide emissions, mandatory standards on renewable energy, mandatory efficiency standards on vehicles and products, and a national carbon dioxide cap-and-trade scheme, according to new research conducted by the University of New Hampshire.

  6. First-ever 'State of the Carbon Cycle Report' finds troubling imbalance
    11-14-2007 · EurekAlert!
    The first "State of the Carbon Cycle Report" for North America, released online this week by the US Climate Change Science Program, finds the continent's carbon budget increasingly overwhelmed by human-caused emissions. North American sources release nearly 2 billion tons of carbon into the atmosphere each year, mostly as carbon dioxide. Carbon "sinks" such as growing forests may remove up to half this amount, but these current sinks may turn into new sources as climate changes.

  7. Ancient climate change may portend toasty future
    12-07-2006 · EurekAlert!
    Scientists, including Ken Caldeira of the Carnegie Institution's Department of Global Ecology, have found that the Earth's global warming, 55 million years ago, may have resulted from the climate's high sensitivity to a long-term release of carbon. This finding contradicts the position held by many climate-change skeptics that the Earth system is resilient to such emissions.

  8. New model revises estimates of terrestrial carbon dioxide uptake
    12-11-2007 · EurekAlert!
    Researchers at the University of Illinois have developed a new model of global carbon and nitrogen cycling that will fundamentally transform the understanding of how plants and soils interact with a changing atmosphere and climate. Current models do not account for nitrogen processing, and probably exaggerate the terrestrial ecosystem's potential to slow atmospheric carbon dioxide rise, the researchers say.

  9. Climate experts search for answers in the oceans
    12-11-2006 · European Space Agency (ESA)
    By absorbing half of the carbon dioxide emitted into the atmosphere, the oceans have a profound influence on climate. However, their ability to take up this carbon dioxide might be impaired as a result of climate change. To determine their response to global warming, ESA has backed two projects that provide systematic data on key oceanic variables – colour and temperature.

  10. Climate policy: It's good to be in the 'RED'
    05-10-2007 · EurekAlert!
    Tropical deforestation, which releases more than 1.5 billion metric tons of carbon to the atmosphere every year, is a major contributor to global climate change. Recognizing this, a group of forest-rich developing nations have called for a strategy to make forest preservation politically and economically attractive. The result is a two-year initiative, dubbed "Reducing Emissions from Deforestation," launched by the United Nations Framework Convention on Climate Change.
