When mere seconds of storm warning could mean the difference between harm or safety, two researchers with Western University ties have developed a tornado-prediction method they say could buy as much as 20 minutes more warning time. These radar-based calculations can forecast a tornado, with 90% accuracy within a 100-kilometer radius, say Anna Hocking, a

A significant thunderstorm and rainfall system is developing across southern and eastern Australia with the potential for widespread flooding threat to parts of Victoria and southern and central New South Wales, the Australian Bureau of Meteorology (BOM) warns. The system will move over South Australia on Thursday, November 30 before impacting Victoria, southern New South Wales and

At least 11 people have been killed after heavy rain produced by Tropical Cyclone “Cempaka” triggered severe floods and landslides in East Java, Indonesia on November 28, 2017. Cempaka is the first named storm of the 2017/18 Australian region cyclone season. In addition to heavy rain, strong winds caused by Cempaka brought volcanic ash from erupting

Around 100 000 residents living near erupting Agung volcano in Bali, Indonesia have been told to evacuate, officials said Monday, November 27, 2017. Late Saturday, November 25, hours the after the second phreatic eruption within a week started, Agung shifted into magmatic phase. Lahars were observed descending down the mountain on Sunday, prompting authorities to

Two bright fireballs were observed streaking through the night sky over southern England, United Kingdom over the past 24 hours. The first at 23:59 UTC on Friday, November 24 and the second at 07:12 UTC on Saturday, November 25, 2017. Sound was associated with both events. The American Meteor Society (AMS) received 81 reports by 17:25 UTC

Over the past couple winters, big displays of pink and white auroras have coincided with spotless suns. The sight is often big enough to make observers wonder if there is a connection, SpaceWeather reports. The most recent remarkable outburst of pink auroras was observed on November 22, 2017, from Tromsø, Norway. “Suddenly, the whole valley turned white (with

A late spring cold snap ripped through western and central Victoria this month, causing extensive agricultural damage. Older farmers in the region say it was ‘the worst frost since 1977.’ Agriculture Victoria’s southwest grains regional manager Rob O’Shannessy estimated farmer losses from the frosts at A$100 – 180 million (US$76 – 137 million). This included

New research on oxygen and iron chemistry under the extreme conditions found deep inside the Earth could explain a longstanding seismic mystery called ultralow velocity zones. The findings could have far-reaching implications on our understanding of Earth’s geologic history, including life-altering events such as the Great Oxygenation Event, which occurred 2.4 billion years ago. Sitting

Major flooding hit Jamaica’s Montego Bay, the capital of Saint James Parish in the country’s northwest, on Wednesday, November 22, 2017. The flooding brought traffic to a standstill, flooded buildings, stranded numerous residents and resulted in severe infrastructural damage. Heavy rains lashed the city for over four hours on Wednesday afternoon, trapping residents in schools and workplaces, and

A new study, published this week in Nature, shows that thunderstorms can also produce radioactivity by triggering nuclear reactions in the atmosphere. This may sound like the plot of a blockbuster science fiction disaster. But in reality, it’s nothing to worry about. Since the early 20th century, scientists have been aware of ionizing radiation – particles and electromagnetic

When a human-made disaster like a chemical spill or nuclear accident occurs, it’s not unusual for the land to be ridden off. But there’s an unlikely candidate that could actually be able to survive the harsh terrain and help the area become viable again – Australian native plants.   “It’s a biotechnology called ‘phytoremediation’ and

The first observation of a super-hydrated phase of the clay mineral kaolinite could improve our understanding of processes that lead to volcanism and affect earthquakes. In high-pressure and high-temperature X-ray measurements that were partly conducted at DESY (German Electron Synchrotron), scientists created conditions similar to those in so-called subduction zones where an oceanic plate dives

Researchers using NASA’s Magnetospheric Multiscale mission (MMS) discovered tornado-like swirls of plasma create a magnetosphere tumultuous enough to let harmful high-energy particles from the Sun slip into near-Earth space. The discovery is important for understanding how the solar wind sometimes enters Earth’s atmosphere. MMS, launched in 2015, uses four identical spacecraft flying in a pyramid formation to

New activity/unrest was reported for 3 volcanoes between November 15 and 21, 2017. During the same period, ongoing activity was reported for 11 volcanoes. New activity/unrest: Agung, Bali (Indonesia) | Oraefajokull, Iceland | Sarychev Peak, Matua Island (Russia). Ongoing activity: Aira, Kyushu (Japan) | Bagana, Bougainville (Papua New Guinea) | Cleveland, Chuginadak Island (USA) | Dukono, Halmahera (Indonesia) | Ebeko, Paramushir

After weeks of silence and denials, Russia has confirmed that it too has detected evidence of a mysterious radiation cloud floating above much of Europe, observing a dramatic radiation spike above Russia’s Ural Mountains. The acknowledgement comes after a number of other European nations suggested Russia was the probable origin of the unexplained radiation surge,

Russia’s meteorological service Roshydromet confirmed Monday, November 20, 2017 that ‘extremely high’ concentrations of the radioactive isotope Ruthenium 106 (Ru-106) were detected in the southern Urals in late September. Roshydromet reported Monday that it measured ‘extremely high’ concentrations of Ru-106 in the southern Urals between September 25 and October 1, 2017, but then contradicted itself and said that ‘some

Heavy rain is wreaking havoc across Jeddah, Saudi Arabia on Tuesday, November 21, 2017, stranding drivers on flooded roads and delaying school classes at least until Thursday.  The Centre for Crises and Disasters in Makkah Region closed a number of roads in Jeddah on Tuesday due to heavy thunderstorms accompanied by active winds that limited

A Co-Rotating Interaction Region (CIR) ahead of isolated positive polarity Coronal Hole High Speed Stream (CH HSS) is affecting our planet today, causing geomagnetic storming.  G1 – Minor geomagnetic storm threshold was reached 05:30 UTC. Over the past 24 hours, solar wind parameters were indicative of a slow solar wind regime followed by onset of a CIR

It’s the hiatus that never happened: an apparent ‘slowdown’ in rising surface temperatures between 1998 and 2012, which encouraged climate change deniers to label global warming a made-up conspiracy. Even a hoax. To be clear, thanks to the efforts of scientists, this ‘pause’ in global warming has been thoroughly debunked, but new research highlights another
