TL;DR: In this article, the authors confirm the significance of greenhouse gas emissions from tropical reservoir but stress the importance of considering all the gas pathways upstream and downstream of the dams and taking into account the reservoir age when upscaling emissions rates at the global scale.

TL;DR: Gases trapped in polar ice proved our most direct record of the changes in greenhouse gas levels during the past 150,000 years, and the best documented trace-gas records are for CO[sub 2] and CH[sub 4] as mentioned in this paper.

TL;DR: The results reported in this paper suggest that during the coldest part of the last Ice Age (20,000-15,000 yr ago) the atmospheric CO2 content was half (0.016%) that of today's level ( 0.033%).

TL;DR: In this paper, the authors report that, as a result of these policy initiatives, lead concentrations in Greenland snow have decreased by a factor of 7.5 over the past twenty years.

TL;DR: In this paper, water-air fluxes were measured in three tropical reservoirs and their respective rivers downstream of the dams and the results showed that despite their relatively small surfaces, rivers downstream downstream of dams accounted for a significant fraction (9 − 33% for CH4 and 7 − 25% for CO2) of the emissions across the reservoir surfaces classically taken into account for reservoirs.
