Scientists have discovered that cosmic rays and clouds affect climate changes in the world. This is what a team of German climate scientists at the Max Planck Institute in Heidelberg demonstrated in their climate study, published by the journal Geophysical Research Letters, issued by the American Geophysical Union.
It stated that they found evidence of the relationship between the aforementioned radiation and climate changes above the Earth. Despite this, the function of these clouds has not yet been fully understood. However, the amounts of cosmic radiation coming towards Earth are largely subject to the influence of the Sun. Some say that the stars have an indirect effect on the general climate above Earth.
Some scientists believe that an important part of the increase in Earth’s temperatures in the twentieth century may be due to changes in the activities of the sun, and not just the so-called global warming resulting from the excessive use of fuel and fossil fuels. The German team installed a huge ion lens. In one of the planes, he found that the measurements he conducted had detected, for the first time, in the upper layers of the atmosphere, huge positive ions in dense numbers. Through their observations, they found strong evidence that clouds play an important role in climate change based on their effect on the ionic nature, formation and growth of these space particles in the upper layers of the atmosphere. This supports the view that cosmic rays can contribute to climate change and affect the ability of clouds to block light.
It was discovered at the Tyndall Center for Research on Climate Change, affiliated with the University of East Anglia in Britain, the importance of clouds in the climate system, and that they have a strong effect on the penetration of rays into the Earth’s atmosphere, because they (clouds) prevent some of the shortwave radiation coming towards the Earth, and absorb ground radiation. Of the type of long waves emanating from the Earth, which results in the blocking of these short rays, and the absorption of long rays, cooling and increasing the temperature of the atmosphere, respectively.
The effect of withdrawal may be significant, but no evidence has yet emerged to support this. Because the lower clouds tend to be cold, while the upper clouds tend towards heat. Therefore, upper clouds block sunlight less than lower clouds, as is known. But clouds are phenomena capable of absorbing infrared radiation. Because the upper layer of high clouds is cooler than its counterpart in low clouds, it reflects less infrared radiation to outer space. But what makes the matter more complicated is the possibility of changing the characteristics of clouds with climate change, and smoke caused by humans can confuse matters regarding the effect of global warming on clouds.
Many geophysicists agree that the temperature of the Earth’s surface has begun to rise, while the temperature levels of the lower layers of the atmosphere remain as they are. But their published research on the effect of cosmic rays suggests that these radiations can cause changes in the outer covering of clouds. This cover may provide an explanation for the heat mystery. In their opinion, the difference in temperatures in the global climate is not caused by human-caused changes to the climate. Because the evidence for this is still weak.
This effect is assumed to appear in a complete rise in temperature from below towards the atmosphere. Although these scientists believe that changes in cloud cover can explain this difference, none of them was able to provide evidence about the reasons for the differences in temperature levels in the global climate. But their recent study suggested that cosmic rays, which are extremely small charges that invade various planets at different scales, depending on the strength of the solar wind, are the cause, and perhaps this is the missing link in the effect of cosmic rays on the climate above our planet.
British physicist Stephen Hawking described climate change on Earth as more dangerous to the planet than terrorism. CNN reported that Hawking’s statements came in the wake of other statements by British scientists at a time when prominent scientists are preparing to push the giant hand of the Doomsday Clock further towards midnight as a symbol of the danger of a devastating global nuclear catastrophe. This is the fourth step since the end of the Cold War era in which the clock has been advanced. “As citizens of the world, we have a duty to warn the general public about the unnecessary risks we live with every day,” Hawking warned.
A British scientist had drawn a terrifying environmental picture for the year 2007, predicting that the phenomenon of global warming would worsen in a way that would make this year one of the hottest years in history. Dr. Phil Jones, Director of Climate Research at the University of East Anglia, predicted major droughts in Australia, hurricanes in Asia, and floods in South America, with the ecological balance expected to be threatened.
The British Treasury previously issued a report revealing that the increase in the proportion of greenhouse gases will lead to a rise in the Earth’s temperature at a rate that nature will not tolerate and may have serious consequences on the environment and geography. Prime Minister Tony Blair said in the introduction to the report, “It is clear today that the emission of greenhouse gases, industrial activity, and the economic growth of the Earth’s population, whose number has increased six-fold in 200 years, (all factors) will lead to a rise in the Earth’s temperature at a rate that will not be tolerated by nature.” Blair added that upon reading the report, it becomes clear that “the risks of climate change are greater than we imagine.”
