A study reveals that a decrease in air pollution causes an increase in global warming

Image
Scientists have discovered a great paradox in nature – clean air drives global warming, while pollution keeps our planet cool. An international team of researchers determined that current pollution levels are 30 percent lower than in 2000, but global warming from carbon dioxide emissions has increased by up to 50 percent. Polluting particles, such as sulfates or nitrates, are known for their reflective properties and are commonly found in exhaust. The team, in a desperate move, proposes to use aerosols again, but uses a controversial type of geoengineering to do so. This method, called solar engineering, requires the release of sulfate particles into the stratosphere which in turn will cause reflective haze to appear around the world, reports Science.org. The study, led by the University of Leipzig, provides good news for human health – these particles are linked to millions of deaths each year – but is bleak for the future of humanity.

Reducing air pollution has INCREASed global warming, research reveals

Image
The big paradox: Reducing air pollution has INCREASED global warming because clean air does not contain aerosol particles that reflect sunlight and cool the Earth Pollution levels today are 30 percent lower than in 2000 However, this has led to increased warming from carbon emissions Scientists find there is less fog in the atmosphere to block out solar radiation They suggest using solar engineering to launch aerosol particles into the atmosphere in an effort to combat climate change By Stacy Liberatore For Dailymail.com Published: 4:56 p.m. EDT, 22 July 2022 | Updated: 5:51 p.m. EDT, 22 July 2022 Scientists have discovered a great paradox in nature – clean air increases global warming, while pollution keeps our planet cool.

Researchers Show Direct Observation of Ice Particles Due to Earth's Rapid Warming

Image
The researchers described direct observations of the particle size of ice nucleation in the middle Arctic throughout the cycle of sea ice development and decline. According to their findings, these particles have distinct seasons, with lower concentrations in winter and spring and higher concentrations during summer melting local flora. The clouds that cover the Earth’s surface and the tiny aerosols in the air known as ice core particles that initiate the formation of ice in these clouds are important contributors to climate change. Climate is strongly influenced by this interaction of heat, cloud cover and ice nucleation. Earth is heating up faster (Photo: Alberto Restifo/Unsplash) But those important ice-forming aerosols, which can be mineral dust, microorganisms, or ocean spray, are almost never investigated in the Arctic, where they are most needed because their effects are little understood, and few scientists have traveled that far north, as per ScienceDaily. However, scient...

Air samples from the Arctic region show how fast the Earth is warming

While climate change is taking effect everywhere on Earth, the Arctic Circle is feeling its effects primarily, in the form of melting glaciers, melting ice sheets, and decreasing sea ice. Key players in climate change include clouds covering the Earth’s surface and microscopic aerosols in the air called ice core particles that seed the formation of ice in these clouds. This dance of ice cores, cloud cover and heat all play a major role in climate. But the all-important ice-forming aerosols, which can be mineral dust, microbes, or ocean spray, are rarely studied in the Arctic – where they need to be studied most – because little is known about their effects there, and not many scientists venture further north. . However, Colorado State University scientists did. In 2019, an intrepid team including atmospheric research scientist Jessie Creamean boarded a ship, sailed north, collected thousands of samples of air, seawater, sea ice, snow, and meltwater, and brought home the physica...

The Arctic is heating four times faster than the rate of global warming

Image
6 July 2022 Reviewed by Alex Smith A new study of observed temperatures reveals that the Arctic appears to be warming four times faster than the rate of global warming. The trend has increased sharply twice in the last five decades. This is a finding that all but four of the 39 climate models missed. Image Credit: Shutterstock.com/ Tomas Rebro Thirty years is considered the minimum time to represent climate change . We reduced the time interval to 21 years. On a smaller time scale and, contrary to previous investigations which found that the Arctic amplification index increased smoothly, we observed two distinct steps, one in 1986 and the second in 1999. . Petr Chylek, Lead Author of the Study, Physicist and Climate Researcher, Los Alamos . National Laboratory The study was reported in the journal Geophysical Research Letter. Decade-by-decade episodic trends defined by Chylek and his collaborators tend to have an impact on global sea levels and weather, which precisely projectin...
