“…Joos et al ( 2017 ) found reduced precipitation for a very polluted case over the warm belts in the western North Pacific. Guo et al ( 2019 ) found that the area-averaged accumulated rainfall and maximum rainfall were lower when they increased the anthropogenic emission by 10 times in their WRF-Chem (Weather Research and Forecasting model coupled to Chemistry) simulations.…”

The government of India imposed a nationwide lockdown to tackle the outbreak of COVID-19 in 2020. This period witnessed record low anthropogenic activity, which had severe socio-economic impacts but also had orthogonal effects on the ambient air quality of the atmosphere. This study focuses on the variations in the atmospheric boundary layer (ABL) over a western Indian urban region in the light of COVID-19. Continuous backscatter recorded by a ceilometer, stationed at Ahmedabad, was used in this study to monitor the ABL during the national lockdown (NLD) in 2020 and state restrictions in 2021, and compared with the control year of 2019. In parallel, improvement in air quality during the NLD was observed by the SAFAR air quality station at Ahmedabad, with decreased particulate matter concentrations. The ground-based observations were substantiated by the ERA5 reanalysis dataset. A decline in the ABL height was recorded during the NLD, which showed improvement in 2021 but which was shy of the ABL in 2019. This was correlated with rain events during the observational period, recorded by an automatic weather station.

The influence of climate change on agriculture, especially as it relates to the production of food, changes with reverence to duration and space, of which most of these influences are diverse and remarkably uncertain. Undoubtedly, the application of food innovation technology (FIT) in the agricultural processes is an important response for operative and objective adaptation and mitigation of climate change. Consequently, there is a need to urgently re-evaluate the procedures for FIT so as to address the diversities and uncertainties ensuing from these influences of climate change on agriculture with the aim of improving the production of food. Therefore, the application of climate-smart agricultural (CSA) activities with resilience in agricultural events as well as more aids in the application of resources for both in the adaptation and mitigation of climate change by means of FIT will be of great assistance in this regard. Hence, this study presents a facile review of some of the topical developments in the production of food with reverence to the influence of climate change on FIT. Some legal frame-work on climate change with respect to FIT are also been discussed.

“…The one generalization that can now be made is that virtually all tropospheric aerosol particulates, including cloud droplets and their aerosol components, absorb short-and long-wave solar radiation, and absorb long-wave radiation from Earth's surface, thus becoming heated. Moreover, aerosols can modify cloud properties and suppress rainfall [74][75][76][77]. As Tao et al [78] note: "Aerosols, and especially their effect on clouds and precipitation, are one of the key components of the climate system and the hydrological cycle.…”

Geophysical Consequences of Tropospheric Particulate Heating: Further Evidence that Anthropogenic Global Warming is Principally Caused by Particulate Pollution

The climate science community and the United Nations’ Intergovernmental Panel on Climate Change have misinformed world governments by failing to acknowledge tropospheric particulate geoengineering that has been ongoing with ever-increasing duration and intensity for decades, and by treating global warming solely as a radiation-balance issue, which has resulted in a seriously incomplete understanding of the fundamental factors that affect Earth’s surface temperature. Here we review the consequences of tropospheric particulate heating by absorption of short- and long-wave solar radiation and long-wave radiation from Earth’s surface. Generally, black carbon absorbs light over the entire solar spectrum; brown carbon absorbs near-UV wavelengths and, to a lesser extent, visible light; iron oxides are good absorbers, the most efficient being magnetite. Pyrogenic coal fly ash, both from coal burning and from tropospheric jet-spraying geoengineering (for military purposes and/or climate engineering), contains carbon and iron oxides, hematite and magnetite. The recently published climate-science paradigm shift discloses that the main cause of global warming is not carbon dioxide heat retention, but particulate pollution that absorbs radiation, heats the troposphere, and reduces the efficiency of atmospheric-convective heat removal from Earth’s surface. In addition to the World War II data, three other independent lines of supporting evidence are reviewed: (1) Passage overhead of the Mt. St. Helens volcanic plume; (2) Radiosonde and aethalometer investigations of Talukdar et al.; and, (3) convection suppression over the tropical North Atlantic caused by the Saharan-blown dust. The risks associated with the placement of aerosol particulates into the stratosphere, whether lofted naturally, inadvertently, or deliberately as proposed for solar radiation management, poses grave risks, including the destruction of atmospheric ozone. To solve global warming humanity must: (1) Abruptly halt tropospheric particulate geoengineering; (2) Trap particulate emissions from coal-fired industrial furnaces (especially in India and China) and from vehicle exhaust; and, (3) Reduce particulate-forming fuel additives.
