has already increased due to extremely warm conditions induced by anthropogenic global warming. Footnotes Author contributions:.S.D.,.L.S., and.T. However, we note that the long-term time series of the pmdi is similar to that of other Palmer drought indicators, particularly at the annual scale ( Figs. For more information about how to write a research paper, see my articles: Steps in Writing a Research Paper: and Writing a Research Paper Outline. Historical occurrence of drought, precipitation, and temperature in California. I suggest that if possible, you a good conclusion sentence for an essay print the articles out before you read them since most people do a better job of reading hard copy articles. From the time series of annual-mean values for each observed or simulated realization, we calculate ( i ) the baseline mean value over the length of the record, ( ii ) the annual anomaly from the baseline mean value, ( iii ) the. 1 C ) has therefore substantially increased the probability that when moderate precipitation deficits occur, they occur during warm years. For example, if your question is "What are the potential benefits and risks of nanotechnology?" and you become more interested in arguing for using nanotechnology for health science, you might change the question to: "How will nanotechnology change medicine for the better?". RCP8.5 has the highest forcing in the second half of the 21st century and reaches 4 C of global warming by the year 2100 ( 52 ).

Our work was supported by National Science Foundation Award 0955283 and National Institutes of Health Award 1R01AI090159-01. 112 (13) ; published ahead of print March 2, 2015. Papers relating to the following topics will be considered: Physiology, genetics, biochemistry, and behavior of microorganisms that are either used to make foods or that represent safety or quality problems. S1 S3 we initially focus on statewide pmdi, temperature, and precipitation averaged over the AugustJuly 12-mo period. However, the occurrence.5 SD precipitation anomalies has not increased in recent years (40 in and 40 in 19952014) ( Fig. The extremely warm and dry conditions have led to acute water shortages, groundwater overdraft, critically low streamflow, and enhanced wildfire risk. New Research In, physical Sciences, featured Portals, articles by Topic, biological Sciences. As a result, Californias per capita water use has declined in recent decades, meaning that additional short-term water conservation in response to acute shortages during drought conditions has become increasingly challenging.
Projected changes in the probability of co-occurring warmdry conditions in the 21st century. 1 C ) has led to a substantial increase in warm conditions, with 80 of years in exhibiting a positive temperature anomaly ( Fig. In this work, we use the pmdi as our primary drought indicator, although we note that the long-term time series of the pmdi is similar to that of the pdsi and phdi, particularly at persuasive essay introduction body conclusion the annual scale considered here ( Figs. The respective criteria are identified by different colors of text. It is also easier to mark them up with a highlighter or notes in the margin. We note that the interplay between the existence of a well-defined summer dry period and the historical prevalence of a substantial high-elevation snowpack may create particular susceptibility to temperature-driven increases in drought duration and/or intensity in California. The pmdi is used as the primary drought indicator, although the other Palmer indicators exhibit similar historical time series ( Figs. For the analysis of all possible 12-mo periods, we generate the annual time series of each 12-mo period (JanuaryDecember, FebruaryJanuary, etc.) using a 12-mo running mean. In addition, the probability of.5 SD precipitation anomaly increases in spring (.001) and autumn (.01) in relative to 19202005, with spring occurrence increasing by 75 and autumn occurrence increasing by 44which represents a substantial and statistically significant increase. We find that although there has not been a substantial change in the probability of either negative or moderately negative precipitation anomalies in recent decades, the occurrence of drought years has been greater in the past two decades than in the preceding century. Because multiple drought indicators reached historic lows in July 2014 ( Figs.
