Scientists warn of unusually cold Sun: Will we face another ice age?
This happened before during the US revolution against the UK. A mini-ice age.
A study by the University of California San Diego has claimed that by 2050, the Sun is expected to become cool. You might think "what's the big deal," but remember that this means the solar activities that create the heat of the Sun to sustain life on Earth may diminish. And the last time it happened was in the 17th Century, when the Thames River froze. Scientists call this the "Maunder Minimum".
Physicist Dan Lubin at the university and his team studied the past event and concluded that were are in for a worse case. The Sun is expected to get much dimmer than last time and, in scientific terms, it is a "grand minimum" -- a time period in the 11-year solar cycle when the solar activities are at the lowest point.
According to the study, titled Ultraviolet Flux Decrease Under a Grand Minimum from IUE Short-wavelength Observation of Solar Analogs and published in the journal Astrophysical Journal Letters, this grand minimum will be 7 percent cooler than such periods from the past.
Scientists also said that the Sun might have another cooling period in a decade.
However, predicting a solar minimum or maximum is a challenge to scientists because of the non-linear characteristic of solar activities that happens every day. During a minimum cycle, though solar cycles still occur, the intensity is very low, while during a maximum cycle, solar flares go up and sun spews out billion-ton clouds of electrified gas into space. These two extremes can bring about some major global and regional climate changes.
