“…The summer, as was mentioned in the description of the general trend, presents slope values near zero in most of the state, which points at a lack of changes in the summer. In this regard, the results of the present study are consistent with those from studies such as [64,67,68], for the states of Zacatecas and Aguascalientes, and with those from [41], which also reports on a decrease in minimum temperatures; however, studies such as [65,66] report partially different results for the Zacatecas region.…”

“…The spatio-temporal evolution of extreme maximum temperature shown in Figure 10b indicates that the highest temperatures occur in areas below 22 • N. The inter-annual behavior can also be inferred from the clearly visible winter seasons, colored in yellow, when TXx decreases by approximately 5 • C. Since 1995, the red tone intensifies with the increasing temperatures in most of the state. Other studies focusing in our study area have also reported increases in maximum temperatures observed in historical series [64][65][66][67], as well as studies performed in other regions in Mexico where maximum temperatures have increased [36][37][38][39]41,68]. The hottest years in the study period are 2009, 2010, and 2011, when temperatures close to 40 • C were recorded throughout the state.…”

“…Nation-wide research such as the study by [41] reports on a trend of increased number of summer days, increased extreme maximum temperature, and lower extreme minimum temperature. Similar studies focused on Zacatecas and other Mexican states confirm the increase in maximum temperature; however, the same result is not true with respect to minimum temperature, since an increasing trend in minimum temperature has also been found in parts of Chihuahua, Veracruz, Chiapas, and Zacatecas [37][38][39][40]65,66]. Trends are therefore observed to vary depending on geographical location, time of the year, and type of temperature (maximum or minimum) [68]; these results are not unlike other findings from studies throughout the globe and are evidence that local and regional trends can be representative of planetary climate [64].…”

Sufficient evidence is currently available to demonstrate the reality of the warming of our planet’s climate system. Global warming has different effects on climate at the regional and local levels. The detection of changes in extreme events using instrumental data provides further evidence of such warming and allows for the characterization of its local manifestations. The present study analyzes changes in temperature and precipitation extremes in the Mexican state of Zacatecas using climate change indices developed by the Expert Team on Climate Change Detection and Indices (ETCCDI). We studied a 40-year period (1976–2015) using annual and seasonal time series. Maximum and minimum temperature data were used, as well as precipitation statistics from the Mexican climatology database (CLICOM) provided by the Mexican Meteorological Service. Weather stations with at least 80% of data availability for the selected study period were selected; these databases were subjected to quality control, homogenization, and data filling using Climatol, which runs in the R programming language. These homogenized series were used to obtain daily grids of the three variables at a resolution of 1.3 km. Results reveal important changes in temperature-related indices, such as the increase in maximum temperature and the decrease in minimum temperature. Irregular variability was observed in the case of precipitation, which could be associated with low-frequency oscillations such as the Pacific Decadal Oscillation and the El Niño–Southern Oscillation. The possible impact of these changes in temperature and the increased irregularity of precipitation could have a negative impact on the agricultural sector, especially given that the state of Zacatecas is the largest national bean producer. The most important problems in the short term will be related to the difficulty of adapting to these rapid changes and the new climate scenario, which will pose new challenges in the future.
