[1] A new model of global climate, ocean circulation, ecosystems, and biogeochemical cycling, including a fully coupled carbon cycle, is presented and evaluated. The model is consistent with multiple observational data sets from the past 50 years as well as with the observed warming of global surface air and sea temperatures during the last 150 years. It is applied to a simulation of the coming...

[1] Two earth-system models of intermediate complexity are used to study the long term response to an input of 5000 Pg of carbon into the atmosphere. About 75% of CO2 emissions have an average perturbation lifetime of 1800 years and 25% have lifetimes much longer than 5000 years. In the simulations, higher levels of atmospheric CO2 remain in the atmosphere than predicted by previous experiments...

Residential energy consumptions of both electricity and fuels are associated with emissions of many air pollutants. Temporally and spatially resolved energy consumption data are scarce in China, which are critical for a better understanding of their environmental impacts. In this study, a space-for-time substitution method was proposed and two models for predicting fuel and electricity consumpt...

UNLABELLED A natural gas burner has been used as a precise and accurate source for generating large quantities of carbon dioxide (CO2) to evaluate emissions measurements at near-industrial scale. Two methods for determining carbon dioxide emissions from stationary sources are considered here: predicting emissions based on fuel consumption measurements-predicted emissions measurements, and direc...

Recently The Economist (2013a), a prominent journalistic advocate of strong policies to control CO2 emissions, expressed their puzzlement on the absence of warming over the last 15 years. They observed that this flat period of global average temperature occurred despite that CO2 emissions from human sources continued at an increased rate. The total human-produced CO2 emissions in that period of...

Sanding to bury the overgrowth of uprights and promote new growth results in alternate sand organic sublayers 0–30 cm layer cranberry soils contributing global carbon storage. The aim this study was measure CO2 emission rates soil under simulated warming. Soil samples (0–10, 10–20 20–30 cm) were incubated jars for up 105 days at 10, 20 30 °C. rate measured biweekly by gas chromatography. increa...

Anthropogenic global warming is driven by emissions of a wide variety of radiative forcers ranging from very short-lived climate forcers (SLCFs), like black carbon, to very long-lived, like CO2. These species are often released from common sources and are therefore intricately linked. However, for reasons of simplification, this CO2-SLCF linkage was often disregarded in long-term projections of...

This study examines dynamic interrelationships and causality relationships among CO2 emissions, economic, political and financial variables over the period of 1971-2011 for the case of Iran as one of the top CO2 emitting countries in the world. The results of ARDL and Johansen cointegration approaches confirm the existence of long run relationship among CO2 emissions, energy consumption, GDP, f...

Aquaculture ponds are dominant features of the landscape in the coastal zone of China. Generally, aquaculture ponds are drained during the non-culture period in winter. However, the effects of such drainage on the production and flux of greenhouse gases (GHGs) from aquaculture ponds are largely unknown. In the present study, field-based research was performed to compare the GHG fluxes between o...

Atmospheric CO2 concentration has increased from 280 ppm during pre-industrial times to 380 ppm today as a result of human input, and this is thought to be causing enhanced global warming and ocean acidification1. Between 2000 and 2005, global CO2 emissions from burning fossil fuels averaged 26.4 Gt CO2 yr−1, at or above the highest rates predicted by the Intergovernmental Panel on Climate Chan...
