Sun will be 7 % cooler by 2050 ' research

Land will get less sunlight

Since the sunlight will be reduced globally, the temperatures are bound to drop as well, offering a natural solution to the issue of global warming, or the climate change.

That time it was called 'Maunder Minimum, ' where the temperature got so low that London's River Thames got frozen. 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.

Current study results were released in a paper in The Astrophysical Journal Letters.

The full statement from the university follows below. They compared radiation from stars that are analogous to the Sun and identified those that were experiencing minima.

The event starts with irregular intervals due to random fluctuations. They have called this upcoming period "grand minimum.' The conditions that were witnessed in Europe during the mid-17th century might just repeat". Furthermore, Baltic Sea also froze, & so it became quite easy for the Swedish Army to invade Denmark in the year 1658. Researchers estimate that the UV radiation will decrease by 7 percent more than in the lowest moments of active cycles. The thing is, after a grand minimum, the sun heats back up again. There are more than 20 years of data from the International Ultraviolet Explorer satellite mission documenting these patterns.

"That thinning in turn changes the temperature structure of the stratosphere, which then changes the dynamics of the lower atmosphere, especially wind and weather patterns", it noted. The cooling is not uniform.

In spite of the chilling weather in Europe during the Maunder Minimum, other areas such as Alaska and southern Greenland warmed.

The Sun has an 11-year cycle of highs and lows, one that scientists are predicting will have an extraordinary low-point in its next cycle. While the help of grand minimum is appreciated and gives humanity a lot of help, it does not stop global warming. The team elaborated that the cooling effect from the grand solar minimum is merely a fraction of the warming effect as a result from the increasing amount of Earth-warming greenhouse gases in the atmosphere. After hundreds of thousands of years of Carbon dioxide levels never exceeding 300 parts per million in air, the concentration of the greenhouse gas is now over 400 parts per million, continuing a rise that began with the Industrial Revolution. The "Maunder Minimum" occurred, as it is known, occurred in between 1645 and 1715.

It found eight of the atolls and nearly three-quarters of the islands grew during the study period, lifting Tuvalu's total land area by 2.9 percent, even though sea levels in the country rose at twice the global average. By the end of the simulated grand solar minimum, however, the warming in the model with the simulated Maunder Minimum had almost caught up to the reference simulation.
