Abstract Uncontrolled emissions of landfill gas may contribute significantly to climate change, since its composition represents a high fraction of methane, a greenhouse gas with 100- year global warming potential 25 times that of carbon dioxide. Landfill cover could create favourable conditions for methanotrophy (microbial methane oxidation), an activity of using bacteria to oxidize methane to carbon dioxide. This paper presents a brief review of methanotrophic activities in landfill cover. Emphasis is given to the effects of cover materials, environmental conditions and landfill vegetation on the methane oxidation potential, and to their underlying effect mechanisms. Methanotrophs communities and methane oxidation kinetics are also discussed. Results from the overview suggest that well-engineered landfill cover can substantially increase its potential for reducing emissions of methane produced in landfill to the atmosphere.

The paper presents a hypothesis of the effect of artificial fumes on the water cycle in nature and the climate of the globe. The contribution of artificial evaporation to the structure and components of the water cycle is estimated quantitatively. The causes of frequent natural disasters observed at present are explained. An opinion was expressed on the role of carbon dioxide in climate change on our planet. Actions are proposed to reduce artificial evaporation, save water, reduce damage from anthropogenic impact on the environment, restore the natural cycle of water in nature.

Carbon dioxide removal (CDR) increasingly features in climate scenarios that hold global warming well below 2°C by 2100. Given the continuous gap between climate mitigation pledges and the emission pathways that are aligned with achieving the temperature goals of the Paris Agreement, we would expect countries to promote CDR in their long-term planning to achieve mid-century targets. Yet, countries may not consider it their responsibility to contribute to the global response to climate change using CDR. Thus, a study of the respective country's long-term climate plans is both timely and vital. Such a study could reveal the pledged collective ambition, the contribution of CDR to the pledged ambition, and how the envisaged role of CDR is described by the different countries. This paper explores the long-term low emission development strategies (LT-LEDS) of countries in order to map the role of CDR in addressing climate change. We also supplement our examination of strategies with the opinions of climate experts. Based on an inductive coding of the material and a literature review, the analytical focus of the analysis includes CDR targets and planning, types of CDR, barriers and opportunities to CDR implementation, as well as international cooperation. Our study of 25 national LT-LEDS submitted to the UN or to the EU, as well as 23 interviews with climate experts, shows that national plans for CDR vary substantially across countries and are generally lacking in detail. The findings also demonstrate that CDR is perceived to be necessary and desirable for achieving mid-century climate goals, but also reveal variation in the intended role of CDR. We use an interpretive approach to outline three possible visions of CDR in climate action: as a panacea, as a necessary fallback and as a chimera. We conclude by discussing what our findings of the envisaged roles of CDR in addressing climate change mean for climate governance. This research thereby contributes to the literature on governing CDR with new comprehensive insights into the long-term climate strategies of countries.
