In fact, we've found that the strongest correlation is the one between the area of the Sun's surface covered with holes and the globally averaged temperature of the Earth.' 'There are other reasons for climate variations that are significant. 'What I am saying is the data do not unambiguously support the contention that CO2 increases are the dominant cause of climate variability,' he added. 'I don't dispute that, and I'm not saying that CO2 can't have significant effects in the future. 'During some parts of the last century, as the amount of CO2 increased, the temperature increased,' he explained.

Most notable in the past two decades have been the warming effects of the 1997-98 El Nino and the general cooling that followed the eruption of Mount Pinatubo in 1991.Īccording to Posmentier, their results do not rule out the possible climate influence of man-made fossil fuels, which have caused the atmosphere's CO2 levels to rise. As Posmentier and colleagues note, other major climate factors are also at work concurrently, thus complicating attempts to correlate Sun-Earth phenomena. Regardless, the percentage of the Sun's surface covered by coronal holes seems to be a fairly accurate indicator of temperature in the Earth's troposphere over months or years. The scientists note, however, that the charged particles hitting the Earth could come from either the Sun, or from galactic cosmic rays that are modulated by the solar wind. Another possibility is that the charged particles change ozone chemistry in the upper atmosphere, in turn affecting the dynamics of the climate. In turn, significant changes in the cloud cover influence the temperature of the lower troposphere, with temperatures falling with increased cloud cover. Posmentier and colleagues think that the connection between the solar wind and climate may be more direct, suggesting that the charged particles hitting the Earth's atmosphere may affect the properties of terrestrial water clouds, particularly the percentage of those clouds covering the Earth. The solar wind has also been long suspected as a possible indirect contributor to terrestrial climate change. At Earth, this hot bath of charged particles produces the aurorae (i.e., the aurora borealis), interferes with electrical and radio transmissions, and may threaten passengers aboard high-flying airliners or astronauts aboard unshielded spacecraft. 'This is the first time anyone has combined these modern, reliable data sets to link solar activity and climate, and to cite several alternative mechanisms that might explain this link,' Posmentier explained.Ĭoronal holes are, literally, gaps in the Sun's outer atmosphere through which the stream of hot, supersonic particles known as the solar wind pours out into space to engulf the entire planetary system. At this point, there is a dropping off of magnetic activity and an enlargement of the coronal holes. Results show a clear drop in terrestrial atmospheric temperature after the Sun's magnetic field activity is most intense. The scientists compared the Earth's temperature with the size of coronal holes reported on the Sun during a two-decade period, starting in January 1979 and ending April 1998. (Like all stars, the Sun will eventually run out of energy – but scientists don’t expect this to happen for another 5 billion years or so.In a paper that appears in the February 28 issue of the journal New Astronomy, climatologist Eric Posmentier of Long Island University's Brooklyn Campus, solar physicists Willie Soon and Sallie Baliunas of the Harvard-Smithsonian Center for Astrophysics and physicist Pius Okeke of the University of Nigeria chart temperature anomalies seen in the Earth's lower troposphere (i.e., the region of atmosphere in which we live) using Microwave Sounding Unit (MSU) radiometers aboard weather satellites. Instead, people build giant rocket thrusters to move the Earth to a new star system.

In the 2019 film “The Wandering Earth,” once again the Sun is dying, but there’s no bomb this time. To save humanity, astronauts try to reignite the Sun with a bomb, though things don't quite go as planned. In the 2007 film “Sunshine,” the Sun is dying, plummeting Earth into a deep freeze. Astronauts are supposed to use a bomb to divert the flare. In the 1990 science fiction film “Solar Crisis,” a huge solar flare is about to scorch Earth.

If you're Superman or a fellow Kryptonian, your powers are heightened by the yellow glow of our Sun, and you can even dispose of dangerous materials, as Superman and Superboy did, by hurling them into the Sun. The Beatles had a hit in 1969 with “Here Comes the Sun.” Other popular songs that reference the Sun include: “Walkin’ on the Sun” by Smashmouth “Ain’t No Sunshine” by Bill Withers “Walking on Sunshine” by Katrina and the Waves “Pocketful of Sunshine” by Natasha Bedingfield and “Let the Sunshine In” by the Fifth Dimension. Countless musicians have written songs about the Sun.
