Abstract This paper analyzes the changes Americans perceive to be taking place in their local weather and tests a series of hypotheses about why they hold these perceptions. Using data from annual nationwide surveys of the American public taken from 2008 to 2011, coupled with geographically specific measures of temperature and precipitation changes over that same period, the authors evaluate the relationship between perceptions of weather changes and actual changes in local weather. In addition, the survey data include measures of individual-level characteristics (age, education level, gender, and income) as well as cultural worldview and political ideology. Rival hypotheses about the origins of Americans’ perceptions of weather change are tested, and it is found that actual weather changes are less predictive of perceived changes in local temperatures, but better predictors of perceived flooding and droughts. Cultural biases and political ideology also shape perceptions of changes in local weather. Overall, the analysis herein indicates that beliefs about changes in local temperatures have been more heavily politicized than is true for beliefs about local precipitation patterns. Therefore, risk communications linking changes in local patterns of precipitation to broader changes in the climate are more likely to penetrate identity-protective cognitions about climate.

Global climate change and warming are altering hemispheric and local weather patterns. Altered weather patterns have great potential to affect the phenology of life history events, such as the initiation of breeding in organisms that reproduce seasonally. Long-distance migratory birds may be particularly challenged by changes in local weather on breeding grounds because they arrive from distant locations and must commence breeding when conditions are appropriate. Here we explore the effects of local temperature on first egg dates and annual productivity in a long-distance Neotropical migratory songbird, the prothonotary warbler Protonotaria citrea. We present results from a 20-year (1994 to 2013) study documenting the detailed nesting activities of a color-marked population (average of 155 individual females each year) of warblers in southern Illinois, United States. The warblers typically arrive in April and start breeding in late April and May in our study system. We tested for an effect of local average April daily temperature and female age on first egg dates, total number of offspring produced per female, and the probability of fledging two broods. We found that warmer April temperatures promoted earlier first egg dates and higher average annual productivity in the warblers. On average, older females had earlier first egg dates than 1-year-old females, but both age groups responded similarly to local April temperatures. The reproductive gains associated with earlier first egg dates in warmer years stemmed from an increased probability of successfully fledging two broods, suggesting that earlier first egg dates do not currently create a mismatch with food (insect) resources. Earliest arrival dates of warblers to the region of our study system were not affected by local April temperatures, suggesting that females vary their first egg date based on conditions they experience/assess after their arrival. Whereas these birds currently adjust the timing of their breeding and actually produce more offspring in warmer years, continued global warming may eventually upset the current balance between arrival dates, food resources, and the commencement of nesting.

AbstractConvective afternoon rainfall (CAR) events, which tend to generate a local rainfall typically in the afternoon, are among the most frequently observed local weather patterns over Southeast Asia during summer. Using satellite precipitation estimations as an observational base for model evaluation, this study examines the applicability of ten global climate models provided by the sixth phase of the Coupled Model Intercomparison Project (CMIP6) in simulating the CAR activities over Southeast Asia. Analyses also focus on exploring the characteristics and maintenance mechanisms of related projections of CAR activities in the future. Our analyses of the historical simulation indicate that EC-Earth3 and EC-Earth3-Veg are the two best models for simulating CAR activities (including amount, frequency, and intensity) over Southeast Asia. Analyses also demonstrate that EC-Earth3 and EC-Earth3-Veg outperform their earlier version (i.e., EC-Earth) in CMIP5 owing to the increase in its spatial resolution in CMIP6. For future projections, our examinations of the differences in CAR activities between the future (2071–2100, under the ssp858 run) and the present (1985–2014, under historical run) indicate that CAR events will become fewer but more intense over most land areas of Southeast Asia. Possible causes of the projected increase (decrease) in CAR intensity (frequency) are attributed to the projected increase (decrease) in the local atmospheric humidity (sea breeze convergence and daytime thermal instability). These findings provide insight into how the local weather/climate over Southeast Asia is likely to change under global warming.

Abstract This paper closely examines Thucydides’ presentation of three naval battles fought in the Corinthian Gulf and the battle of Sybota off north-west Greece, in order to show how his version of the action does not just stress the pervasive impression of Athenian dominance and downplay the Peloponnesian performance, but extends to characterising the Corinthian fleet in a surprisingly negative way. In the first battle he claims that they were ignorant of the local weather patterns, in the second of the underwater hazards, and after the third that ‘The Corinthians believed they were victors if they were only just defeated’. His account of the earlier battle off Corcyra is similarly flawed, since by focussing on the participants’ treaty obligations he fails to bring out the significance of the Corinthian naval victory for the history of Greek warfare. The reader of The Peloponnesian War is encouraged not to question Thucydides’ disparaging record of the Corinthian navy, as it reinforces his focus on a bipartite contest between Athens and Sparta. However, a case is made here for a more positive assessment of Corinthian involvement in the modified design of the trireme and the revision of naval tactics in the late fifth century BC.

Agriculture faces critical challenges caused by changing climatic factors and weather patterns with random distribution. This has increased the need for accurate local weather predictions and weather data collection to support precision agriculture. The demand for uninterrupted weather stations is overwhelming, and the Internet of Things (IoT) has the potential to address this demand. One major challenge of energy constraint in remotely deployed IoT devices can be resolved using weather stations that are energy neutral. This paper focuses on optimizing the energy consumption of a weather station by optimizing the data collected and sent from the sensor deployed in remote locations. An asynchronous optimization algorithm for wind data collection has been successfully developed, using the development lifecyle specifically designed for weather stations and focused on achieving energy neutrality. The developed IoT weather station was deployed in the field, and it has the potential to reduce the power consumption of the weather station by more than 60%.

Climatically similar regions may experience different temperature extremes and weather patterns that warrant global comparisons of local microclimates. Urban agroecosystems are interesting sites to examine the multidimensional impacts of climate changes because they rely heavily on human intervention to maintain crop production under different and changing climate conditions. Here, we used urban community gardens across the California Central Coast metropolitan region, USA, and the Melbourne metropolitan region, Australia, to investigate how habitat-scale temperatures differ across climatically similar regions, and how people may be adapting their gardening behaviors to not only regional temperatures, but also to the local weather patterns around them. We show that, while annual means are very similar, there are strong interregional differences in temperature variability likely due to differences in the scale and scope of the temperature measurements, and regional topography. However, the plants growing within these systems are largely the same. The similarities may be due to gardeners’ capacities to adapt their gardening behaviors to reduce the adverse effects of local temperature variability on the productivity of their plot. Thus, gardens can serve as sites where people build their knowledge of local weather patterns and adaptive capacity to climate change and urban heat. Climate-focused studies in urban landscapes should consider how habitat-scale temperature variability is a background for interesting and meaningful social-ecological interactions.

Abstract I analyzed the occurrences of 217 species of migrant landbirds on Southeast Farallon Island, 43 km west of San Francisco, California, from 10 yr of daily censuses, fall 1968 to spring 1978. I divided species into 12 subgroups to reflect seasonal and geographical distributions on the mainland. The abundances of the various subgroups on the Farallones, in both fall and spring, were directly related to the proximity to the island of their breeding and wintering ranges and normal migration routes. For most subgroups, abundances were greater in fall than in spring. The great majority of fall individuals were hatching-year birds, and I suspect that many, if not most, spring individuals were second-year birds. Highly significant year-to-year variations occurred in the number of individuals that arrived on the Farallones and in the proportion of individuals in the various subgroups, despite the fact that the number of species and proportion of species in the various subgroups remained statistically invariant from year to year. Of particular interest were 5 fall days and 4 spring days when exceptional numbers of birds arrived on the island. These wave days were probably the result of local weather conditions near the Farallones. The numbers of individuals of most subgroups of wintering and summering species, especially coastal subgroups, increased significantly on wave days, but the numbers of vagrants did not. The annual variations in abundance of Farallon landbirds were probably caused by variations in the number of young produced each summer, by long-range weather patterns acting over large areas of the continent, and by variations in local weather conditions. Vagrant species significantly increased in abundance in both fall and spring during the second 5 yr of this study. I suggest that this could be caused by a selective increase in the proportion of dispersing individuals (including vagrants) in populations subjected to increased rates of habitat change.

A healthy 33 year old male presented in December with a 3 week history of fever and fatigue. He had been deer-hunting in northern Minnesota 1 month prior and had sustained a tick bite. Extensive laboratory investigations and a lumbar puncture were conducted. He was empirically with doxycycline and had rapid improvement in his symptoms. Subsequently, PCR and serologic testing returned positive for Anaplasma phagocytophlium. Anaplasmosis is a tick-borne illness caused by the bacterium Anaplasma phagocytophilum and is typically seen in the warmer months. This patient’s presentation in December was uncommon for a tick-borne illness in Minnesota. Regional weather records demonstrated unseasonably warm temperatures during the patient’s trip. Ixodes ticks are known to be sensitive to temperature and humidity, which likely contributed to increased tick activity, leading to disease transmission. This case highlights the importance for clinicians to be aware of local weather patterns and how this might influence seasonal disease presentations.

We are only two or three breeding cycles from 9 billion people and an altered climate. This future population will rightly expect to access a nutritious, balanced and affordable diet, and to expect that the animals and plants it comes from are produced sustainably. However, during the same period there will be changes to the global climate resulting in local weather patterns with more frequent extreme events. To ensure medium-term food security will be challenging; to ensure it over the longer-term without permanently degrading the natural resources of our planet will need step-changes in agricultural systems. Breeding new varieties of plants will be a necessity to meet these future needs, but achieving this through conventional methods is likely to prove problematic. The novel technique of genome editing, with its ability to turn off or improve existing genes, may well be the answer to this problem.
