Detailed explanation-1: -The effect is so pronounced, the study finds, that if all the trees in the tropics were cut down global temperature could increase by as much as 0.7 degrees. With the trees gone the air warms up, creating large, rising masses of warm air.
Detailed explanation-2: -Deforestation results in decreased number of trees leading to accumulation of carbon dioxide in the atmosphere. Carbon dioxide in the atmosphere traps heat rays reflected by the earth which results in global warming.
Detailed explanation-3: -According to the report, with global warming of 1.5 °C there would be increased risks to “health, livelihoods, food security, water supply, human security, and economic growth.” Impact vectors include reduction in crop yields and nutritional quality.
