Removing methane from the air is possible, but do the costs outweigh the benefits? This note explores the question of whether removing methane from the atmosphere is justifiable. Destruction of methane by oxidation to CO 2 eliminates 97% of the warming impact on a 100-yr time scale. Methane can be oxidized by a variety of methods including thermal or ultraviolet photocatalysis and various processes of physical, chemical or biological oxidizers. Each removal method has energy costs (with the risk of causing embedded CO 2 emission that cancel the global warming gain), but in specific circumstances, including settings where air with high methane is habitually present, removal may be competitive with direct efforts to cut fugitive methane leaks. In all cases however, great care must be taken to ensure that the destruction has a net positive impact on the total global warming, and that the resources required would not be better used for stopping the methane from being emitted. This article is part of a discussion meeting issue ‘Rising methane: is warming feeding warming? (part 2)’.

Targeting at students randomly selected across all departments and all years at one university located in northern Taiwan, this research based on hierarchical regression analysis aims to investigate whether or not global warming awareness education exerts a positive effect on research participants’ energy-saving cognition and attitude. the results indicate that the 8 hypotheses proposed are all supported. Firstly, green education courses and global warming awareness videos have significantly positive impact on participants’ cognition and attitude as compare to their peers who did not take the courses or view the videos. Secondly, the participants’ scientific literacy positively influences their energy-saving cognition, which in turn positively impacts on energy-saving attitude. Furthermore, energy-saving cognition plays a completely intermediate role between scientific literacy and energy-saving attitude. Results mentioned conclude the contributions of this research.

Methane (CH4) is one of the most abundant organic gases in the atmosphere. Recently the importance of CH4 as a greenhouse gas has been recognized and studies have been carried out to asses its contribution to global warming. In this paper we show that atmospheric CH4 is produced by a wide variety of natural and anthropogenic processes. Then, we discuss mainly production, consumption and emission of CH4 in paddy fields. Finally, we provide an estimate of the mitigation potential in agricultural systems including rice production, ruminant animals and animal waste.

Significant problems have arisen in the last years, such as climate change, global warming, and hunger. These complications are correlated with the depletion and exploitation of natural resources and environmental contamination. Due to overcrowding, the list of challenges for the next few years is growing. A comprehensive approach was made to the agro-industrial production of Avocado (Persea americana) and the management of all its biomass waste. So, bioprocesses and biorefinery can be used to produce high added-value products. A large number of residues are composed of lignin and cellulose. They have many potentials to be exploited sustainably for chemical and biological conversion; physical, chemical, and natural treatments improve the following operations. There are some applications to many fields such as pharmaceutical, medical, material engineering, and environmental remediation. Possible pathways are mentioned to take advantage of Avocado as biofuels, drugs, bioplastics, and even in the environmental part and emerging technologies such as nanotechnology using bioprocesses and biotech. In conclusion, Avocado and its waste could be transformed into high value-added products in industries above to mitigate global warming and save non-renewable energy.

The influencing factors of the low-carbon consumption behavior of urban residents have become popular. This paper explored the factors of consumers’ low-carbon behavior through a questionnaire survey. Using Hangzhou as a case study city, which yields 786 valid responses, the results indicated that urban consumers generally had a high perception of low-carbon behavior. At the same time, low-carbon cognition and low-carbon intention had a positive impact on residents’ low-carbon behavior. In particular, the level of awareness of global warming adjusted residents’ understanding of low-carbon behavior. From a policy point of view, this research contributes to insights into the promotion of guiding residents’ low-carbon behavior and improving the response to global warming.

Abstract In this paper, the modulations of the North Atlantic tripole (NAT) decadal variability from global warming are studied by conducting a series of coupled ocean–atmosphere experiments using the Fast Ocean Atmosphere Model (FOAM). The model reasonably captures the observed NAT decadal variability with a preferred time scale of about 11 years. With the aid of partial-blocking and partial-coupling experiments, it is found that the NAT decadal cycle can be attributed to oceanic planetary wave adjustment in the subtropical basin and ocean–atmosphere coupling over the North Atlantic. In a doubled CO2 experiment, the spatial pattern of the NAT is preserved; however, the decadal cycle is significantly suppressed. This suppression appears to be associated with the acceleration of oceanic planetary waves due to an increase of buoyancy frequency in global warming. This shortens the time from a decadal to an interannual time scale for the first-mode baroclinic Rossby waves to cross the subtropical North Atlantic basin, the primary memory for the NAT decadal variability in the model. The modeling study also found that the global warming does not modulate the North Atlantic air–sea coupling significantly, but it may be model dependent.

Microbial fermentation for bio-based products is quickly becoming an integral component of the world infrastructure, as the processes encompassing the synthesis of these natural products becomes more efficient, environmentally friendly and cost effective to compete with existing products. Rising energy costs and increased awareness of global warming have motivated production of biomass-derived fuels and polymers. Bio-butanol and bio-ethanol are currently the most desired fermentation products, as these compounds can be applied to multiple uses, including the foundation for green fuel sources. This review focuses on biofuel production; butanol and ethanol from yeast and bacteria, and how these products are efficient and can be suitable alternative for petrochemical products. It also focuses on utilizing waste to be used as the carbon source for microorganisms to produce bio-based products in an attempt to reduce the overall cost.
