“…Due to the need to change our fossil-based economy to a renewable based one, [1][2][3][4][5][6] methods to transform renewables with high selectivity are in demand. Thereby fatty acids can be considered as a broadly available raw material and selected methods for their transformation have been reported.…”

“…Carbon demand has intensified with the increase in economic growth and is proportional to the life quality index . Most carbon has been procured from fossil resources since the Industrial Revolution . Obsessive reliance on fossil resources to meet the enormous demand for carbon inevitably leads to unwanted socioeconomic tension due to the uneven geographical distribution and finite nature of the resources. , In addition, anthropogenic carbon discharge (CO 2 ) into the atmosphere arising from the consumption of fossil resources is one of the key contributors to the earth’s carbon cycle, exceeding the full capacity of natural carbon sink .…”

Microalgal biomass has a high CO2 fixation and growth rate when using CO2 as a carbon source. Moreover, biomass can also be employed as a carbon resource to produce biofuels and chemicals. As the growth rate of extremophilic microalgae remains unaffected by harsh conditions, the present study proposes that these microalgae (such as Galdieria sulphuraria) are a rapidly growing carbon resource for syngas production. Hence, two different experiments were performed as part of this study: (1) cultivation of G. sulphuraria under outdoor conditions and (2) conversion of G. sulphuraria into syngas. The productivity of G. sulphuraria under mixotrophic condition (0.82 g L–1 d–1) was about 1.6 faster than a widely cultivated Chlorella sp. HS2. Moreover, G. sulphuraria was converted into syngas using CO2 as a co-feedstock. The simultaneous reduction of CO2 and the oxidation of volatile matter (VM) from the thermolysis of G. sulphuraria promoted syngas formation. The chemical reaction was influenced by the molecular size of the VMs. In the presence of the Ni catalyst, low-molecular-weight VMs were formed owing to chemical bond scissions. Syngas formation under CO2 doubled compared with that under inert conditions. The findings suggest that G. sulphuraria is a feasible carbon source for CO2 fixation and chemical production.

“…It is well-known that changes in the climate can be attributed to anthropogenic and natural events" activities (Knowles & Cayan, 2002). These include man-made activities, such as the burning of fossil fuels and deforestation, which lead to the emission of greenhouse gases, release of toxic and obnoxious wastes, and reductions in carbon sinks (Duchemin, 2022). In contrast, contiguous natural events include volcanic eruptions, shifts in tectonic plates, variations in the sun"s intensity, gravitational force fields and geoid heights as well as the albedo effect, El Niño and La Niña, etc.…”

World climate continues to deteriorate at varying rates in spite of different anthropogenic mitigative and adaptive interventions. Conversely, the gravitational force fields of the sun and moon hold Earth in orbit, amongst others. Herein, we explore the impacts of changes in these gravitational fields on global climate and examine their influences on natural events, such as ocean tides, volcanoes, geomagnetic storms and movement of tectonic plates. Beyond reports on greenhouse effect and mass transport, we discuss the influence of gravity on tidal bulges, melting glaciers, condensable atmosphere and other events, such as El Niño and La Niña, and correlate their typically subtle impacts on climate worldwide with variations in Earth’s gravity. The intention is to highlight other causative factors implicated in climatic change without diminishing the contributions of greenhouse gasses and other factors, which are currently regarded, by specialists and lay-public alike, as the major culprits of climate change. We submit that the shifts in Earth’s gravitational fields to sustain equilibrium and remain in orbit can manifest as perturbations of atmospheric temperatures, pressures and air concentrations as well as volume changes and ion effects; in hydrological bodies, and are some of the non-anthropogenic agents driving changes in global climate. We surmise, therefore, that the influence of changes in gravity, albeit subtle, on climate change is significant. It is envisaged that highlighting these subtle agents of change would intensify efforts toward ameliorating and/or eliminating drastic and deleterious changes in climate as well as at embracing adaptive measures at local and international levels.
