Atmospheric benzenoid emissions from plants rival those from fossil fuels

Atmospheric benzenoid emissions from plants rival those from fossil fuels

Despite the known biochemical production of a range of aromatic compounds by plants and the presence of benzenoids in floral scents, the emissions of only a few benzenoid compounds have been reported from the biosphere to the atmosphere. Here, using evidence from measurements at aircraft, ecosystem, tree, branch and leaf scales, with complementary isotopic labeling experiments, we show that veg...

Energy from Fossil Fuels.

Hydrogen Production from Fossil Fuels

A review of conventional methods of production of hydrogen from fossil fuels is presented. Some advanced and unconventional methods of production of hydrogen based on fossil fuels are also presented. The general characteristics of the feedstocks used to produce hydrogen are first described. This is followed by the chemistry required to generate hydrogen. Then the chemical process operations and...

From fossil fuels to renewable energies

This paper describes the model of an industrial society based on fossil fuels whose supply decreases and the society is forced to develop alternative energy sources. It is conceived as an abstract model that captures the basic aspect of such a change, but in a simple and schematic way. Despite this, most of the important dynamics of this problem are included in the model. The results show inter...

Doctors call for divestment from fossil fuels.

©2015 8872147 Canada Inc. or its licensors CMAJ, September 22, 2015, 187(13) E403 For a third year in a row, a group of eco-conscious physicians will campaign at the Canadian Medical Association (CMA) General Council Aug. 23–26 for physician associations to divest from fossil fuels and reinvest in renewable energy. The international divest–invest movement, which has been gaining momentum since ...
