To what extent has mass deforestation made us more susceptible to extreme weather?

The relationship between deforestation and the incidence of flooding is well known and something I understand. I have wondered recently how deforestation may have left other parts of this world similarly vulnerable to weather events such as tornadoes or hurricanes, now that we lack the natural barrier to violent winds that large forests may have represented. I am sure that research and conclusions to the question are already out there, but is it as commonly known as those other factors of climate change we hear about more often, i.e., pollution and decreasing biodiversity? We constantly hear about how our actions have produced extreme weather, but not often in the context of letting it affect us all the more extremely because we have compromised an essential form of protection.

    Nov 23 2011: Another issue with deforestation is an increase of CO2 in the atmosphere. Trees remove CO2 from the air and store carbon in their mass while releasing oxygen back into the atmosphere as a by product. CO2 is on of the greenhouse gasses that trap heat in the atmosphere causing a myriad of issues from more extreme weather to rising sea levels.

This is a problem, when it is a particularly rainy season or if there is a storm, because the roots holds shallow soil in place. When it rains heavily along a area with steep slopes, it can create devastating landslides or mudslides.
  • Nov 21 2011: A hectare of forested landscape evaporates roughly10x more water than a hectare of sea. Forests have an important role in the water cycle. Evapotranspiration causes large amounts of energy to be transferred into the upper atmosphere. Energy is used, turning water into steam and then released when steam turns to rain drops. It is therefore not difficult to imagine the implications of less forest or dense vegetation cover of some kind. Its a simple model that is relatively unstudied or even acknowledged.
