Atmospheric carbon dioxide concentration has increased globally from about 280 ppm before the Industrial Revolution (Pearman 1988) to about 353 ppm in 1990. That increase, and the continuing increase at a rate of about 1.5 ppm per annum, owing mainly to fossil fuel burning, is likely to cause change in climate, in primary productivity of terrestrial vegetation (managed and unmanaged), and in the degree of net sequestration of atmospheric CO into organic form. The quantitative role 2 of the latter in attenuating the increase in atmospheric CO concentration itself is 2 an important but uncertain element of the global carbon-cycle models that are required to predict future increases of atmospheric CO concentration. 2 In my experience in workshops and other multidisciplinary gatherings, argument arises in discussion of this topic among different groups of scientists such as bioclimatologists, plant physiologists, biogeochemists and ecologists. Plant concentration physiologists are often impressed by the positive effect of higher CO 2 on plant growth under experimental controlled environments and argue that this would be at least partly expressed in the field for many species and communities.
The master of horror returns to comics with this fresh reanimation of a horror classic! The iconic R.L. Stine is joined by artist A.L. Kaplan (Maw, Jim Henson's The Storyteller) in this twisted retelling of Frankenstein. You might be familiar with the story of a mad scientist hell-bent on creating life, but what these two demented brothers have made is something else entirely! Horror lovers won’t want to miss this imaginative retelling with more than a few twists, as R.L. Stine takes on one of the most iconic stories in horror history! Collects Stuff of Nightmares #1-4.
The book describes the innovations that enabled botany, in the Eighteenth century, to emerge as an independent science, independent from medicine and herbalism. This encompassed the development of a reliable system for plant classification and the invention of a nomenclature that could be universally applied and understood. The key that enabled Linnaeus to devise his classification system was the discovery of the sexuality of plants. The book, which is intended for the educated general reader, proceeds to illustrate how many aspects of French life were permeated by this revolution in botany between about 1760 to 1815, a botanophilia sometimes inflated into botanomania. The reader should emerge with a clearer understanding of what the Enlightenment actually was in contrast to some popular second-hand ideas today.
R.L Stine is back—but not for the faint of heart—with a chilling take on an iconic character, perfect for fans of Fear Street and EC Comics horror titles! In Stine’s reanimated reimagining, you’re familiar with the classic tale of a mad scientist hell-bent on creating life, but what these two demented brothers have created is something else entirely!
