    Proc Natl Acad Sci U S A 101:16109-14. 2004
    ..These emissions, an indirect effect of all climate forcings, are small compared with human-made climate forcing and occur on a time scale of a few centuries, but they tend to aggravate the task of stabilizing atmospheric composition...
  2. pmc Trends of measured climate forcing agents
    J E Hansen
    National Aeronautics and Space Administration, Goddard Institute for Space Studies, New York, NY 10025, USA
    Proc Natl Acad Sci U S A 98:14778-83. 2001
    ..Nevertheless, practical constraints on changes in emission levels suggest that global warming at a rate +0.15 +/- 0.05 degrees C per decade will occur over the next several decades...

    Proc Natl Acad Sci U S A 101:423-8. 2004
    ..However, soot contributions to climate change do not alter the conclusion that anthropogenic greenhouse gases have been the main cause of recent global warming and will be the predominant climate forcing in the future...

    James Hansen
    NASA Goddard Institute for Space Studies and Columbia University Earth Institute, New York, NY 10025, USA
    Philos Trans A Math Phys Eng Sci 365:1925-54. 2007
    ..Some forcings are especially effective at high latitudes, so concerted efforts to reduce their emissions could preserve Arctic ice, while also having major benefits for human health, agricultural productivity and the global environment...
  6. pmc Global temperature change

    National Aeronautics and Space Administration Goddard Institute for Space Studies, Columbia University Earth Institute, and Sigma Space Partners, Inc, 2880 Broadway, New York, NY 10025, USA
    Proc Natl Acad Sci U S A 103:14288-93. 2006
    ..We conclude that global warming of more than approximately 1 degrees C, relative to 2000, will constitute "dangerous" climate change as judged from likely effects on sea level and extermination of species...

    James Hansen
    Earth Institute, Columbia University, New York, New York, United States of America
    PLoS ONE 8:e81648. 2013
