How does extensive deforestation increase global temperatures?

Answer 1

Trees absorb CO2. Deforestation decreases the number of trees worldwide, which results in less CO2 absorption, which leads to an increased greenhouse effect, which leads to higher global temperatures.

Deforestation accounts for 18% of anthropogenic (human caused) greenhouse gas emissions worldwide.

Answer 2

It is very simple. Just about anyone can understand it. Do this simple experiment. Stand in the shade, either under a tree or on the north side of a building. Now stand in the sun. You can notice the difference in temperatures - in the sun it's hot, in the shade it's cool. Now multiply that by the many thousands of places where roads and buildings and parking lots have replaced trees and forests. Also, the forests clear the air, the younger trees and saplings producing more oxygen and taking away more carbon dioxide. Take away all those forests, as we have done, and you have a lot of heat that isn't going away. Add emissions from vehicles and factories and homes and you have the gases that help to trap the heat. All this is how extensive deforestation increases global temperatures. One might say we are headed for hell in a handbasket as the saying goes, only in this case it is in the literal sense.

This is just a simple, common sense way of looking at global warming that anyone can understand. Scientists and other professionals can also notice these changes and, using the tools of their trades, can gage how much the temperatures are increasing and how it is affecting the world now and in the future.

Answer 3

forests absorb heat as well as carbon ,they also produce humidity.

humidity produces vapor which deflects the sun
and with more heat absorbed the place is cooler
walk in a rain forest ,or on the dessert ,and you will see the difference,
being under the canopy of a huge forest can be coolish even on the equator

Forest regulate our climates ,in the day they make it cooler ,and at night they release heat
,
Dessert are freezing cold in the night and you cook in the day.

Take away the forests and the air will be full of man produced carbon, intensifying Global warming ,( the natural carbon production will be far less ,as forests also produce carbon)

Added to that ,are the effects of less humidity and more heat that is not cooled down

Answer 4

Well aside from the CO2 that doesn't get absorbed the trees absorb sunlight and provide shade which everyone knows lowers temperatures.

Answer 5

Trees absorb CO2 .
Trees absorb heat.
Trees provide shade which reduces water evaporation on ground thus keeping it cool.
Trees provide food and timber too.

So cutting trees increases heat and CO2 levels and pollution too.
