The above figure indicates global average forcing of greenhouse gases (GHGs) and aerosols (click here). While the forcing of heating factors such as GHGs is estimated with low uncertainties, those of aerosols are considered to provide direct and indirect cooling effects; altering the effect of cloud albedo through cloud microphysical process is considered an indirect effect. However, uncertainties in the estimate of the cooling effect are still large. In addition, some theoretical studies tell us that cloud distributions in the warmed world will change and cause heating, not cooling, but predictions of the cloud radiative forcing by current climate models are scattered in both cooling and heating directions. GCOM-C aims to observe long-term trends of horizontal distributions of aerosols and clouds on a global scale over 13 years and to estimate the cooling effects of aerosols with high accuracy in order to contribute to enhancing the accuracy of climate models.
Additionally... Anthropogenic carbon dioxide causing the heating of Earth is also increasing the level of pollens from plants into the air. That means CO2 is directly responsible of increasing the risks from asthma and other lung diseases.

The increase in asthma incidence, prevalence, and morbidity over recent decades presents a significant challenge to public health. Pollen is an important trigger of some types of asthma, and both pollen quantity and season depend on climatic and meteorologic variables. Over the same period as the global rise in asthma, there have been considerable increases in atmospheric carbon dioxide concentration and global average surface temperature. We hypothesize anthropogenic climate change as a plausible contributor to the rise in asthma. Greater concentrations of carbon dioxide and higher temperatures may increase pollen quantity and induce longer pollen seasons. Pollen allergenicity can also increase as a result of these changes in climate. Exposure in early life to a more allergenic environment may also provoke the development of other atopic conditions, such as eczema and allergic rhinitis. Although the etiology of asthma is complex, the recent global rise in asthma could be an early health effect of anthropogenic climate change. Key words: aero- allergens, anthropogenic cimate change, asthma, carbon dioxide, phenology, pollen, temperature.

Global Trends in Asthma
...Evidence for the global increase in the burden of asthma has come from studies of incidence, prevalence, and morbidity. Asthma prevalence appears to have increased since the early 1960s (Beasley 2002), with the rise in asthma prevalence occurring among both chil- dren and adults (Beasley et al. 2000) and in a wide range of countries with differing lifestyles (Beasley 2002). Over a similar period, the prevalence of other atopic disorders, such as allergic rhinitis, atopic eczema, and urticaria, has also increased, once again throughout the world (Bach 2002; Beasley 2002). Figure 1 shows increasing prevalence of asthma in several locations. Although different diagnostic definitions have been used in different loca- tions, each location shown is internally consis- tent, and each shows an increase in asthma prevalence.
It has been known for over five decades. Five decades of research. It is hideous to continue to deny the warming of the planet due to the high levels of CO2.
The USA has made some stupid decisions regarding land use under the prior administration as well. It’s pathetic already.
Droughts and destroyed ice fields are everywhere including Greenland which is deteriorating at an accelertating rate. The problem with people that are "The Deniers" is that they actually believe they can live through climage change, and denying the anthropogenic reasons for global warming is to maintain ’status quo’ economics. Life on Earth as we know it will end if the CO2 content of Earth's troposphere is not brought under control. Earth is a planet. It is NOT a toy or some market strategy. I promise you the changes that happen on a dynamic that huge won’t allow humans to survive.
There are no winners in Climate Change. It is a Lose-Lose situation. "Survival of the Fittest" does not apply to Climate Change. Look at it this way, human live in a VERY NARROW window of temperature tolerance. They live with a specific demand for oxygen. Those windows close quickly when the 'biotic content' of Earth is unbalanced.
...The proposed regulations would apply to large-scale industrial sources (click title to entry - thank you) of heat-trapping gases, including power plants, factories and refineries, but not to smaller sources such as new schools, as some critics of EPA action had feared. The rules would force new or substantially modified industrial plants emitting at least 25,000 tons of greenhouse gases a year to employ "best available control technologies and energy-efficiency measures" to minimize emissions. That would cover the sources responsible for 70% of greenhouse gas emissions in the U.S., the EPA said -- primarily carbon dioxide created by burning fossil fuels....
