    Separating signal and noise in atmospheric temperature changes: The importance of timescale (2011)
    Wiley
    Details
    Publication Date: 2011-11-18
    Description: We compare global-scale changes in satellite estimates of the temperature of the lower troposphere (TLT) with model simulations of forced and unforced TLT changes. While previous work has focused on a single period of record, we select analysis timescales ranging from 10 to 32 years, and then compare all possible observed TLT trends on each timescale with corresponding multi-model distributions of forced and unforced trends. We use observed estimates of the signal component of TLT changes and model estimates of climate noise to calculate timescale-dependent signal-to-noise ratios (S/N). These ratios are small (less than 1) on the 10-year timescale, increasing to more than 3.9 for 32-year trends. This large change in S/N is primarily due to a decrease in the amplitude of internally generated variability with increasing trend length. Because of the pronounced effect of interannual noise on decadal trends, a multi-model ensemble of anthropogenically-forced simulations displays many 10-year periods with little warming. A single decade of observational TLT data is therefore inadequate for identifying a slowly evolving anthropogenic warming signal. Our results show that temperature records of at least 17 years in length are required for identifying human effects on global-mean tropospheric temperature.

    Climate extremes: observations, modeling, and impacts (2000)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2000-09-23
    Description: One of the major concerns with a potential change in climate is that an increase in extreme events will occur. Results of observational studies suggest that in many areas that have been analyzed, changes in total precipitation are amplified at the tails, and changes in some temperature extremes have been observed. Model output has been analyzed that shows changes in extreme events for future climates, such as increases in extreme high temperatures, decreases in extreme low temperatures, and increases in intense precipitation events. In addition, the societal infrastructure is becoming more sensitive to weather and climate extremes, which would be exacerbated by climate change. In wild plants and animals, climate-induced extinctions, distributional and phenological changes, and species' range shifts are being documented at an increasing rate. Several apparently gradual biological changes are linked to responses to extreme weather and climate events.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Easterling, D R -- Meehl, G A -- Parmesan, C -- Changnon, S A -- Karl, T R -- Mearns, L O -- New York, N.Y. -- Science. 2000 Sep 22;289(5487):2068-74.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉National Oceanic and Atmospheric Administration (NOAA)/National Climatic Data Center, 151 Patton Avenue, Asheville, NC 28801, USA. david.r.easterling@noaa.gov〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11000103" target="_blank"〉PubMed〈/a〉

    The greenhouse effect in central north america: if not now, when? (1991)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1991-03-01
    Description: Climate models with enhanced greenhouse gas concentrations have projected temperature increases of 2 degrees to 4 degrees C, winter precipitation increases of up to 15 percent, and summer precipitation decreases of 5 to 10 percent in the central United States by the year 2030. An analysis of the climate record over the past 95 years for this region was undertaken in order to evaluate these projections. Results indicate that temperature has increased and precipitation decreased both during winter and summer, and that the ratio of winter-to-summer precipitation has decreased. The signs of some trends are consistent with the projections whereas others are not, but none of the changes is statistically significant except for maximum and minimum temperatures, which were not among the parameters predicted by the models. Statistical models indicate that the greenhouse winter and summer precipitation signal could have been masked by natural climate variability, whereas the increase in the ratio of winter-to-summer precipitation and the higher rates of temperature change probably should have already been detected. If the models are correct it will likely take at least another 40 years before statistically significant precipitation changes are detected and another decade or two to detect the projected changes of temperature.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Karl, T R -- Heim, R R Jr -- Quayle, R G -- New York, N.Y. -- Science. 1991 Mar 1;251(4997):1058-61.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17802090" target="_blank"〉PubMed〈/a〉

    Amplification of surface temperature trends and variability in the tropical atmosphere (2005)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2005-08-16
    Description: The month-to-month variability of tropical temperatures is larger in the troposphere than at Earth's surface. This amplification behavior is similar in a range of observations and climate model simulations and is consistent with basic theory. On multidecadal time scales, tropospheric amplification of surface warming is a robust feature of model simulations, but it occurs in only one observational data set. Other observations show weak, or even negative, amplification. These results suggest either that different physical mechanisms control amplification processes on monthly and decadal time scales, and models fail to capture such behavior; or (more plausibly) that residual errors in several observational data sets used here affect their representation of long-term trends.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Santer, B D -- Wigley, T M L -- Mears, C -- Wentz, F J -- Klein, S A -- Seidel, D J -- Taylor, K E -- Thorne, P W -- Wehner, M F -- Gleckler, P J -- Boyle, J S -- Collins, W D -- Dixon, K W -- Doutriaux, C -- Free, M -- Fu, Q -- Hansen, J E -- Jones, G S -- Ruedy, R -- Karl, T R -- Lanzante, J R -- Meehl, G A -- Ramaswamy, V -- Russell, G -- Schmidt, G A -- New York, N.Y. -- Science. 2005 Sep 2;309(5740):1551-6.

    Modern global climate change (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-12-06
    Description: Modern climate change is dominated by human influences, which are now large enough to exceed the bounds of natural variability. The main source of global climate change is human-induced changes in atmospheric composition. These perturbations primarily result from emissions associated with energy use, but on local and regional scales, urbanization and land use changes are also important. Although there has been progress in monitoring and understanding climate change, there remain many scientific, technical, and institutional impediments to precisely planning for, adapting to, and mitigating the effects of climate change. There is still considerable uncertainty about the rates of change that can be expected, but it is clear that these changes will be increasingly manifested in important and tangible ways, such as changes in extremes of temperature and precipitation, decreases in seasonal and perennial snow and ice extent, and sea level rise. Anthropogenic climate change is now likely to continue for many centuries. We are venturing into the unknown with climate, and its associated impacts could be quite disruptive.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Karl, Thomas R -- Trenberth, Kevin E -- New York, N.Y. -- Science. 2003 Dec 5;302(5651):1719-23.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉National Oceanic and Atmospheric Administration, National Climatic Data Center, Satellite and Information Services, 151 Patton Avenue, Asheville, NC, 28801-5001, USA.

    Observed impact of snow cover on the heat balance and the rise of continental spring temperatures (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-01-14
    Description: Analysis of satellite-derived snow cover, radiative balance, and surface air temperature over Northern Hemisphere extratropical land shows that the retreat of the Northern Hemisphere's extent of spring snow cover over the past 20 years parallels a change in the influence of snow cover on the radiative balance and an observed increase of spring temperatures over the same area. These results help explain why the long-term (20th century) increase in surface air temperature over Northern Hemisphere land has been greater in spring than in any other season relative to the interannual variability.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Groisman, P Y -- Karl, T R -- Knight, R W -- New York, N.Y. -- Science. 1994 Jan 14;263(5144):198-200.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17839175" target="_blank"〉PubMed〈/a〉

    CLIMATE CHANGE. Possible artifacts of data biases in the recent global surface warming hiatus (2015)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2015-06-06
    Description: Much study has been devoted to the possible causes of an apparent decrease in the upward trend of global surface temperatures since 1998, a phenomenon that has been dubbed the global warming "hiatus." Here, we present an updated global surface temperature analysis that reveals that global trends are higher than those reported by the Intergovernmental Panel on Climate Change, especially in recent decades, and that the central estimate for the rate of warming during the first 15 years of the 21st century is at least as great as the last half of the 20th century. These results do not support the notion of a "slowdown" in the increase of global surface temperature.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Karl, Thomas R -- Arguez, Anthony -- Huang, Boyin -- Lawrimore, Jay H -- McMahon, James R -- Menne, Matthew J -- Peterson, Thomas C -- Vose, Russell S -- Zhang, Huai-Min -- New York, N.Y. -- Science. 2015 Jun 26;348(6242):1469-72. doi: 10.1126/science.aaa5632.
