Moderately strong M3.4 solar flare erupted from eastern limb

Moderately strong solar flare reaching M3.4 at its peak time erupted on August 21, 2014. The event started 13:19, peaked at 13:31 and ended at 13:42 UTC. The source was new active region located on the eastern limb. If Coronal Mass Ejection was generated by this event it would likely be directed away from Earth.This region produced several C-class solar flares in last 24 hours and is likely to produce more.NOAA SWPC forecasters estimate 10% chance for M-class, and 1% chance for X-class solar flare in next two days.SunspotsThere are currently 7 numbered sunspot regions on the disk. Region 2146 (N10E14, Cso/beta) grew during in last 24 hours and was responsible for two notable events. The first was a C2/Sf flare at 20/2157 UTC. This event was accompanied b… »

A shocking study - regional climate influenced by the Sun

A new study from Lund University in Sweden has, for the first time, reconstructed solar activity during the last ice age and showed that the regional climate is influenced by the Sun.For the first time, a research team has been able to reconstruct the solar activity at the end of the last ice age, around 20 000 – 10 000 years ago, by analysing trace elements in ice cores in Greenland and cave formations from China.During the last glacial maximum, Sweden was covered in a thick ice sheet that stretched all the way down to northern Germany and sea levels were more than 100 metres lower than they are today, because the water was frozen in the extensive ice caps. The new study shows that the sun’s variation influences the climate in a similar way regardless of whether… »

Five tornadoes sweep through Genoa, northern Italy

Five tornadoes swept through northern Italy on Tuesday, August 19, 2014, prompting flights to be diverted and causing millions of Euros worth of damage. The tornadoes hit around the port city of Genoa. Some eyewitnesses claim they came close to hitting the wreck of the Costa Concordia cruise ship. La Repubblica reported that flights to the city’s airport were diverted. Trains were also interrupted and roads closed. Damage is said to amount to millions of Euros, with roofs ripped off buildings in the Prà neighborhood and the seafront strewn with sun loungers hit by the stormy weather. 100 mm of rain fell in just 1 hour (between 11:00 – 12:00 local time). In the last Genoa flood, on November 4, 2011, 180 mm of rain was reported in one hour.”Local… »

Minor variations in the ice sheet size sufficient to trigger abrupt climate changes

Over the past one hundred thousand years cold temperatures largely prevailed over the planet in what is known as the last ice age. However, the cold period was repeatedly interrupted by much warmer climate conditions. Scientists have long attempted to find out why these drastic temperature jumps of up to ten degrees took place in the far northern latitudes within just a few decades. Now, for the first time, a group of researchers at the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI), have been able to reconstruct these climate changes during the last ice age using a series of model simulations.The surprising finding is that minor variations in the ice sheet size can be sufficient to trigger abrupt climate changes. The new study was published online in the sc… »
