A hundred and more experts in solar physics, geomagnetism, climate change modeling and atmospheric chemistry put their heads together in conducting a study about the effects of solar activity on Earth's climate. Results show variations in ultraviolet radiation that trigger changes in the regions near the equator as well as in polar area.
According to Natural News, researchers said that the data also revealed solar winds affect Earth's global electric fields and this in turn also affects aerosol formation and rainfall. The Sun's current activity is likely to lessen over time which leads to slight reductions in global warming or climate change over the next decades.
The study was funded by the Swiss National Science Foundation through which a team of researchers has created a model to determine the impact of the activity of the Sun in Earth's temperature that triggers climate change. The result of the calculation model shows that the planet's temperature is projected to drop by 0.5 degrees Celsius once the Sun's activity diminishes to its minimum compared to the 1950's data gathered.
However, the global cooling will not fully counteract with the human-induced global warming. "We could win valuable time if solar activity declines and slows the pace of global warming a little towards climate change," PMOD director and project lead Werner Schmutz said. "This will be no more than borrowed time since the next minimum will inevitably follow by a maximum," Schmutz added.
In the article published by National Wildlife Federation, greenhouse gasses such as carbon dioxide, methane, and water vapor traps the heat in the Earth's atmosphere and warm the planet. These greenhouse gasses increase the effect of the average temperature of the Earth which in turn supports life. But with too much of these gasses, the Earth will heat up above the survivable levels as well as climate change.
A pre-industrial concentration of carbon dioxide in the atmosphere was 280 parts per million but as of December 2016, the concentration of CO2 reaches 404.93 ppm. This data shows that the amount of carbon dioxide is higher compared to any time in the last 800,000 years that result in climate change.
Scientists predicted that the effects of climate change will make the sea level raise one to six feet by the end of the 21st century. The Glacier National Park will lose all its glaciers as well as rain forest destruction and coral bleaching that will eventually result in a 25 percent to 35 percent of all animal and plant species be at risk for extinction.
Likewise, the team that came from Physical Meteorological Observatory Davos, ETH Zurich, University of Bern and Swiss Federal Institute of Aquatic Science and Technology, looked at the effects of solar activity on Earth's past climates. They calculated the Sun's radiative forcing such as electromagnetic and particle radiation that will result in climate change.
Amidst all the assertions, the lead of the study Werner Schmutz pointed out that solar fluctuations have been made available only recently and the Sun's activities over the following years are yet to be examined. "To that extent, our latest results are still a hypothesis. But since we are observing constantly strong phase since 1950, it is likely that we will experience a low point in 50 to 100 years' time," Schmutz added.
