We had Global Warming in the desert before the 'vegetated areas' ...

It is about the humidity. Vegetated areas have a higher humidity than desert areas. Water vapor in the air is the greatest resistance to temperature change, not carbon dioxide. When the humidity is low temperatures will change more rapidly than when the humidity is high, both directions, both up and down. So consequently nightime temperatures also drop faster at night in desert areas also.

The vegetation absorbs a lot of the sun's radiation and provides shade, which makes for cooler air to mix with the sun's heat during the day. The desert is just one big convection oven.
The opposite for night, though. Because the vegetation traps heat as well as provides for shade, the heat is not dissipated as quickly, as any sweltering night spent in some tropical jungle will prove to you. On the other hand, the desert heat dissipates quickly, and it can get quite cold in the desert at night.

The desert has nothing to moderate the temperature. Its just sand. A vegetated area gives off moisture. Which creates climate changes. Trees are the lungs of the world. They suck in carbon dioxide and give off oxygen. A desert has nothing to do this with.

the climate is not determined by the landscape, the landscape is determined by the climate. in vegitated areas, the air was cool enough for plants to grow. however in areas that are now deserts, the air was too hot for most plants to grow and survive
(well, technically speaking, the desert is just a wastland where nothing is growing, so deserts can be very, very cold too.... and [just so u know] u said the wrong kind of desert in your question.... DESERT is a baren wasteland, DESSERT is what you eat after dinner)

It only seems like the vegitation has an effect on the surrounding climate. but really it is the climate that has an effect on the vegitation. The desert has desert plants. If you were to plant rainforest plants in the desert it wouldn't become a rainforest. and the climate wouldnt change.

The act of water evaporating out of the leaves of plants (transpiration) uses heat energy out of the air, so the air is cooled by this evaporation.
Also, vegetation shades the ground so there isn't as much light being absorbed and changed into heat.

cause the sun reflects off the ground. in vegetaed areas the plants store the suns energy. thus keeping it warmer at night as well. at least in the dessert ya'll get a break from the heat at night

The shade the plants create cool the surrounding air.
Vegetation also absorbs the light and heat and releases oxygen, and the evaporation of the plants fluids makes the air cooler as well.
