Whatpercent27s the temperature on the outside - Cold weather temporarily reduces EV battery range. While some of this is due to science, and the fact that the cold slows down chemical reactions, most of it seems to be a result of climate control in EVs. AAA tested the range effects of 20F degree weather on several popular EVs and found that temperature alone could reduce range by 10-12% ...

 
Since 1901, the average surface temperature across the contiguous 48 states has risen at an average rate of 0.17°F per decade (see Figure 1). Average temperatures have risen more quickly since the late 1970s (0.32 to 0.55°F per decade since 1979).

The temperature outside is important not only for knowing if you need to wear a jacket, but also for monitoring climate change over time. To measure the temperature, thermometers have historically used the fact that liquids such as mercury and alcohol expand when heated. These thermometers are reasonably accurate, to within a degree or two.On a day when it’s warmer than 80 °F outside, and your A/C (with a clean filter) has been running for at least 15 minutes (to let the temperature in the ductwork stabilize), put a thermometer on the intake vent that’s closest to your inside cooling equipment. Keep it there for about 5-10 minutes and note the temperature. For example, when the air temperature is 30ºF, a brisk wind of even 10 miles per hour lowers the wind chill factor to about 21ºF, which is about the limit for safe play. An air temp of 25ºF and a light wind of 5 mph make for a wind chill of 19 ºF. 3. Know the danger zones for heat index.According to this method, one can determine how much moist a moisturizer must spray. In practise, one should adopt a worst-case scenario. For example, in winter at an outside temperature of -10 °C and a relative humidity of 30%, one wishes to create a satisfactory indoor climate (such as 20 °C and a minimal relative humidity of 40%).Outdoor summer and winter design temperatures and relative humidity for US states and cities. The table below indicates the summer and winter design conditions in US states and cities. 7:30 am. 7:30 am.The core cannot store an excessive amount of heat without upsetting its delicate thermal balance. Your ability to cope with heat, both at rest and during work, depends upon the stability of your core body temperature. If the core temperature can be stabilized at a high of 100oF (38oC), you will probably be safe.
