In the units of 1 million km^2, what is the difference of savanna and scrub during the Holocene and the last glacial maximum?

    The Quaternary Environments Network’s comparative study on planetary vegetation identifies four different categories of savanna and scrub. At the last glacial maximum, about 18,000 years ago, there were 18.66 million square km of savanna and scrub on the earth. In the Holocene era (today), the total has risen to 20.68 million square km. The QEN homepage provides an interesting atlas of the different vegetation types, broken down by region.
