There are approximately 2.5 million dairy cows in California. Emission inventories list dairy cows and their manure as the major source of regional air pollutants, but data on their actual emissions remain sparse, particularly for smog-forming volatile organic compounds (VOCs) and greenhouse gases (GHGs). We report measurements of alcohols, volatile fatty acids, phenols, and methane (CH4) emitt...

Studies have reported important effects of recent climate change on Antarctic species, but there has been to our knowledge no attempt to explicitly link those results to forecasted population responses to climate change. Antarctic sea ice extent (SIE) is projected to shrink as concentrations of atmospheric greenhouse gases (GHGs) increase, and emperor penguins (Aptenodytes forsteri) are extreme...

INTRODUCTION U.S. greenhouse gas (GHG) emissions rose 16 percent between 1990 and 2004, while those from light-duty vehicles rose 23%. (EPA 2006) During the same period, GDP increased 51% (BEA 2005) and VMT rose 37% – more than doubling the nation’s population increase. (Davies et al. 2007 and EPA 2006) While GHGs are on the rise, public policy can result in substantial energy savings. U.S. Cor...

In Northern and Central Europe, short-rotation coppices (SRC) have become a profitable agricultural production alternative, particularly for marginal fields with suitable groundwater levels. The replacement of fossil fuels by the wood chips produced in SRC contributes to the mitigation of greenhouse gases (GHGs). Due to heterogeneous regional production conditions, the impacts on economy, produ...

A field experiment was conducted at Agricultural College & Research Institute, Tamil Nadu University, Madurai during 2021to quantify the GHG emission in puddled rice, ADT 54. The laid out Randomized Block Design with four replications treatments, T1 - SRI method of rice cultivation organic farming SOP, T2 inorganic T3 T1+BGA application @ 10 kg ha-1, T4 T2+ BGA T5 -T1+Azolla 250 T6 -T2+ Azo...

We hypothesized that lignin decomposition microbial consortium would make rice-straw faster as straw contain around 15–24% lignin. In this study, we isolated aerobic degrading microbes from four natural sources and based on their ability towards degradation strains combination (2 bacteria (LB 8, LB 18) 2 fungi (LF 3, LF 9) were selected for rice decomposition. The greenhouse gases emission, enz...

Measuring greenhouse gas (GHG) profiles with global coverage and high accuracy and vertical resolution in the upper troposphere and lower stratosphere (UTLS) is key for improved monitoring of GHG concentrations in the free atmosphere. In this respect a new satellite mission concept adding an infrared-laser part to the already well studied microwave occultation technique exploits the joint propa...
