The Mediterranean has been identified as a ‘climate change hot spot’, already experiencing faster warming rates than the global average, along with an increased occurrence of heat waves (HWs), prolonged droughts, and forest fires. During summer 2021, faced severe HWs, triggering hundreds wildfires across region. Greece, in particular, was hit by one most intense HWs its modern history, national all-time record temperatures being observed from 28 July to 6 August 2021. HW associated extreme...
Abstract. We present a long-term series of surface solar radiation (SSR) from the city Athens, Greece. SSR measurements were performed 1954 to 2012, and before that (1900–1953) sunshine duration (SD) records used in order reconstruct monthly SSR. Analysis whole data set (1900–2012) mainly showed very small (0.02 %) changes 1900 1953, including maximum decrease −2.9 % decade−1 during 1910 1940 period, assuming linear change. For dimming period 1955–1980, −2 was observed matches various...
Intensification of extreme temperatures combined with other socioeconomic factors may exacerbate human thermal risk. The disastrous impacts weather during the last two decades demonstrated increased vulnerability populations even in developed countries from Europe, which are expected to efficiently manage adverse weather. study aims assess trends exposure European using updated historical climatic data large cities different local climates and a set bioclimatic indices. Colder experience...
Abstract The observed and projected precipitation variability in Athens is assessed for a 2.5 century period. examined using the 150‐year historical record of National Observatory Athens, while future an ensemble regional climate models.

Finding one's geographical position (fix) without the use of a Global Navigation Satellite System (GNSS), which was common place before establishment latter, could be tedious and/or inaccurate. Apart from sound knowledge spherical trigonometry and navigational methods, it also requires navigator's approximate or assumed position, current year's celestial bodies' ephemeris (Nautical Almanac), graphical methods (Lines Position – LOP) sometimes can prove wanting in accuracy challenging for...
Diurnal Temperature Range (DTR), defined as the difference between daily maximum (Tmax) and minimum (Tmin) air temperature, has received considerable attention an important indicator of climate change. In present study, we analyse long-term highly homogenized DTR data from 51 Greek stations investigate their spatiotemporal changes. The temporal changes revealed mixed patterns with both increasing decreasing trends over study period distinct seasonal differentiations. pattern in Athens...
Over the past decades, extreme weather phenomena like hot extremes and heat waves (HWs) stand out as a major threat for humans ecosystems. Compound are understood simultaneous, concurrent or sequential events, taking place at single different locations. events may exacerbate risk increase associated adverse impacts, compared to individual events. In study, we examined occurrence of compound an urban site eastern Mediterranean over century-long period, using historical climatic records...
<p>Today, there is a strong scientific consensus that severe weather phenomena and climatic extremes represent an increasing threat in the background of climate change, with profound unpredictable impacts on environment, economy humans.  Heat waves (HWs) particular, are among most disastrous across globe, imposing significant pressure human health, heat being associated thousands excess deaths past. Considerable recent research focuses study main characteristics...
