A single tree can drop surface temperatures by twenty degrees

Official weather reports often mask the true intensity of urban heat because they measure air temperature under standard, shaded conditions. On the streets of Delhi, while the air may be recorded at 43.5 degrees Celsius, thermal imaging reveals that the actual surfaces humans touch and stand upon can soar to 64 degrees. These temperatures are high enough to cause the human body to cease working normally, potentially leading to organ failure and death if the core body temperature exceeds 40 degrees.
