The Impact of Global Warming and Desertification - thought

The lockdowns and reduced societal activity related to the COVID pandemic affected emissions of pollutants in ways that slightly warmed the planet for several months last year, according to new research led by the National Center for Atmospheric Research NCAR. The counterintuitive finding highlights the influence of airborne particles, or aerosols, that block incoming sunlight. When emissions of aerosols dropped last spring, more of the Sun's warmth reached the planet, especially in heavily industrialized nations, such as the United States and Russia, that normally pump high amounts of aerosols into the atmosphere. Temperatures over parts of Earth's land surface last spring were about 0. The effect was most pronounced in regions that normally are associated with substantial emissions of aerosols, with the warming reaching about 0. The new study highlights the complex and often conflicting influences of different types of emissions from power plants, motor vehicles, industrial facilities, and other sources. While aerosols tend to brighten clouds and reflect heat from the Sun back into space, carbon dioxide and other greenhouse gases have the opposite effect, trapping heat near the planet's surface and elevating temperatures. The Impact of Global Warming and Desertification

Reductions in aerosol emissions had slight warming impact, study finds

An abstract is required. Changes in precipitation then serve to increase the frequency and intensity of extreme weather events like floods, droughts, heatwaves, hurricanes and tornados.

However, other scientists maintain that man and his carbon dioxide emissions are not solely to blame for the temperature changes, that prediction of these changes has yet to become percent accurate, and that the perceived temperature rise can never annihilate life on earth. This paper examines the clashing scientific opinions less for the purpose of determining which side presents the stronger arguments but more for drawing the information on the causes and effects of global warming.

As the ice melts, land or open water appears in its place, neither of which is as reflective as ice and thus absorbs more solar radiation Murray 6. This causes more warming and more melting. Thus, most scientists believe greenhouse gases are the primary cause of global warming such that human activity is entirely to blame for this phenomenon. Indeed man is responsible for at least some of the greenhouse gases and carbon dioxide emissions, but many climate experts dispute the view that ascribes temperature changes to rising carbon dioxide levels.
