A recent study conducted by the Scripps Institution of Oceanography at the University of California San Diego found that the sun may emit less radiation by mid-century. This, in theory, should give the planet a chance to warm more slowly but not completely counter the effects of climate change. This “cooldown” of the sun would be the result of a phenomenon called the grand minimum. The grand minimum occurs when the sun\u2019s magnetic field diminishes, sunspots form infrequently, and less UV radiation makes it to the planet\u2019s surface. It is theorized that this results from fluctuations in the sun\u2019s magnetic field, happening completely at random.
\n“There is a well-known 11-year cycle in which the sun\u2019s ultraviolet radiation peaks and declines as a result of sunspot activity,” read a recent Scripps press release. “During a grand minimum, Lubin estimates that ultraviolet radiation diminishes an additional seven percent beyond the lowest point of that cycle. His team\u2019s study,\u00a0\u2018Ultraviolet Flux Decrease Under a Grand Minimum from IUE Short-wavelength Observation of Solar Analogs,\u2019\u00a0appears in the publication\u00a0Astrophysical Journal Letters\u00a0and was funded by the state of California.”
\n“This slowing down will only last 2 to 3 solar cycles,” said Dan Lubin, a research physicist at Scripps. “That\u2019s a span of 3 or 4 decades at most, during which time, the sun may dim about 2\/10ths of a percent.”
\nAlthough this is not a new phenomenon, with sunspots having been observed by both Galileo and English mathematician Thomas Harriot in 1610, there is, in comparison with the earth\u2019s existence, limited historical data. Lubin adds that the cooling of Europe during the 17th century was comparable to what we may see mid-century. “We really don\u2019t have a large historical record of these occurrences,” said Lubin. “For this reason, our team has been working at solar reduction re-creation. This involves looking at stars similar to the sun in a grand minimum state, then estimating the climatic effects.”<\/p>","protected":false},"excerpt":{"rendered":"
