TL;DR: In the past 50 years, the fraction of CO2 emissions that remains in the atmosphere each year has likely increased, from about 40% to 45%, and models suggest that this trend was caused by a decrease in the uptake of CO 2 by the carbon sinks in response to climate change and variability as mentioned in this paper.

TL;DR: In this article, the authors consider the evolving relationship between land-use change and greenhouse gas emissions in Brazil and argue that strong enforcement of sector-oriented policies and solving long-standing land tenure problems, rather than simply waiting for market self-regulation, are key steps to buffer the detrimental effects of agricultural intensification at the forefront of a sustainable pathway for land use in Brazil.

TL;DR: The patterns of N and P cycling during secondary forest succession are similar to N- and P-cycling patterns during primary succession as soils age over thousands and millions of years, thus revealing that N availability in terrestrial ecosystems is ephemeral and can be disrupted by either natural or anthropogenic disturbances at several timescales.

TL;DR: In this paper, the authors found that 77% of carbon transported by water from the landscape was as terrestrially-respired CO2 dissolved within soils, over 90% of which evaded to the atmosphere within headwater reaches of streams.

TL;DR: In this paper, the effects of urban sewage on the dissolved oxygen (O2), dissolved inorganic (DIC) and organic carbon (DOC), and electrical conductivity (EC) in 10 small streams of the Piracicaba River basin, southeast region of Brazil were investigated.
