The paper suggested that the global warming due to greenhouse gases would tend to have less effect with greater densities, and while aerosol pollution could cause warming, it was likely that it would tend to have a cooling effect which increased with density.
This has led to increases in mean global temperature, or global warming. The likely range of human-induced surface-level air warming by 2010–2019 compared to levels in 1850–1900 is 0.8 °C to 1.3 °C, with a best estimate of 1.07 °C. This is close to the observed overall warming during that time of 0.9 °C to 1.2 °C.
This section details production sites at single locations where the most pollution exists or existed in the recent past. During March 2020, Secunda CTL, owned by Sasol, a synthetic fuel [21] and chemicals from coal [22] plant in Secunda, South Africa, was the producer of the single most emissions, at 56.5 million tonnes of CO 2 a year.

While climate change skeptics like Sen. James Inhofe, R-Okla., have pointed to the continued existence of cold weather as a sign that global warming is a threat that humanity need not take ...
Feedbacks associated with sea ice and snow cover are widely cited as one of the principal causes of terrestrial polar amplification. [12] [13] [14] These feedbacks are particularly noted in local polar amplification, [15] although recent work has shown that the lapse rate feedback is likely equally important to the ice-albedo feedback for Arctic amplification.

The Union of Concerned Scientists points to the concern that the use of climate engineering technology might become an excuse not to address the root causes of climate change. [76] However, several public opinion surveys and focus groups reported either a desire to increase emission cuts in the presence of climate engineering, or no effect.
[266] [267] Climate change mitigation is interconnected with various health co-benefits, such as those from reduced air pollution. [267] Air pollution generated by fossil fuel combustion is both a major driver of global warming and the cause of a large number of annual deaths. Some estimates are as high as 8.7 million excess deaths during 2018.
