Rising humidity levels will greatly increase and worsen the effects of rising temperatures on people in many parts of the world — up to the point of precluding
Deadly humidity. By the 2070s, high wet-bulb readings that now occur maybe only once a year could prevail 100 to 250 days of the year in some parts of the tropics. In the southeast United States, wet-bulb temperatures now sometimes reach an already oppressive 29 or 30 degrees Celsius (84-86F); by the 2070s or 2080s, such weather could occur 25 to 40 days each year, say the researchers.
designed specifically for agricultural professionals, the kestrel 3500 delta t provides delta t readings. delta t is the spread between the wet bulb temperature and the dry bulb temperature, and it offers a quick guide to determining acceptable spraying
