Atmospheric abudance of trace gases since the pre-industrial time has forced the earth's climate to change, threatening food security. Exchange of biogenic trace gases between the atmosphere and the biosphere is directly or indirectly influenced by the plants. This volume contains the latest findings on the correlation between the climate change and biogenic gas emission, plant response to elevated levels of carbon dioxide, temperature, ozone and UV-B in combination and alone, regulatory mechanism of methane, nitrous oxide and ammonia emission and their mitigating options. Ecologists, atmospheric scientists, plant physiologists, research scholars, teachers and post-graduate students will benefit from this book.

Called the firebox of the atmosphere, the tropics absorb more energy from the Sun than they lose through longwave emissions; this excess energy activates processes in the temperate and polar regions of the Earth. This book documents the historical evolution of concepts which describe the complex interactions of scales of motion which connect the surface, mixed, and cloud layers to the deeper atmosphere of the tropics. Thermodynamic and kinematic consequences of these transfers of energy are extended to the geochemical and living worlds.
