IT'S GETTING HOTTER ......... Than We Think

Are we safe from the sun?

"Solar flares keep on getting stronger - with latest hotspot the size of 15 Earths strung together."


Scorching temperatures in June's second half helped the continental United States break its record for the hottest first six months in a calendar year, the National Oceanic and Atmospheric Administration said on Monday. The last 12 months also have been the warmest since modern record-keeping began in 1895, narrowly beating the previous 12-month period that ended in May 2012. (Reuters)



The biggest flares are known as 'X-class flares' based on a classification system that divides solar flares according to their strength. The smallest ones are A-class, which are similar to normal background levels, followed by B, C, M and X.

Similar to the Richter scale for earthquakes, each letter represents a 10-fold increase in energy output, meaning an X is ten times an M and 100 times a C. The sun is now heading into the peak of its 11-year solar flare cycle, with 2013 expected to the tumultuous year. With the increased spread in communications in the last 11 years, a sever solar storm could cause huge issues for the planet. More at DailyMail
