Over the last few centuries we've done massive changes to the surface of the planet. In some places there has been deforestation, or otherwise removal of trees, and converting these areas to crops (grains, corn, wheat, pasture land, hay, vegetables, etc. Some irrigated, some not. This would include both hardwoods (leafy trees) and softwoods (evergreen trees). Does this increase or decrease the Radiative Forcing (I.E. The heat being transferred from the sun into the environment)?
