take 10% of the trees out of Texas and the whole region will warm

10% of the trees in Texas died in 2011.  Drought and fire the primary cause of death.

In some areas, with a little rain, new growth will begin, grass, weeds, maybe trees.  In some of the harshest areas the sun will fall on bare earth and rock and the temperature increase will make it unlikely plants can return.    This is the warming feedback loop. Warm temperatures cause something to happen, which accelerates that very process to become more severe and operate faster.  It gets hot and kills trees, plants die so no longer shades the earth, the soil and rocks are hotter causing even more plants to die from heat.  We see this feedback also in the polar regions with ice melt, we see it in China and in Africa in the quickening growth rate of deserts.
