However, the estimated spline curve of EDV decreased when daily mean temperature exceeded around 30°C.
In Byske, the mean temperature exceeds 10 °C for approximately 3 months of the year (June = 11.1 °C; July = 14.5 °C; August = 13.4 °C) (http://www.smhi.se/klimatdata/meteorologi/2.1240).se/klimatdata/meteorologi/2.1240
Specifically, positive associations between ED visits for asthma and inversions were present when PM10 exceeded 32.50 μg/m, maximum temperature exceeded 4.03°C, or mean temperature exceeded –0.75°C, whereas inversions were not associated with ED visits when PM10 was ≤ 32.50, maximum temperature was ≤ 4.03, or mean temperature was ≤ –0.75 (Table 3).
But the slope decreased when daily mean temperature exceeded around 30°C visually which may indicating acclimatization and self-protection of the population, as some of the emergency department visits were not very urgent cases, and patients without severe illnesses may choose to stay at home and delay their hospital visit activity on days with extreme temperature.
There was a statistically significant increased health risk if the mean temperature exceeded the historical 90th, 95th or 98th centile for at least two, three and four consecutive days after adjustment for confounders including long-term trends, day of week, relative humidity, PM10, NO2 and O3 (Table 7).
In these regions, annual NPP by the year 2100 will average 13.9 t ha-1 (compared to the continental average of 8.8 t ha-1) with average annual mean temperatures exceeding 27°C.
The estimated RR of all-cause mortality increased significantly (p < 0.05) when daily mean temperatures exceeded the 93rd percentile thresholds in UK regions and Australian cities.
According to the IPCC's Fourth Assessment Report, 20 30% of plant and animal species are likely to be at increasingly high risk of extinction as global mean temperatures exceed 2 3°C above preindustrial levels (Fischlin et al. 2007).
18, 31 A recent study suggested that dengue transmission is dependent on daily temperature and temperature range; when mean temperatures exceed 18°C, larger diurnal temperature ranges decrease transmission, presumably because of a reduction in vector survival and viral amplification during the cooler hours of each day.
