Stunning halo seen around the sun in Milwaukee, Wisconsin

Milwaukee solar halo
What in the world is a solar halo? We got quite a few pictures sent to us today at Weather Watch 12 with a circle around the sun.

This is known as a solar halo or 22° halo. It occurs when you have a sunny day with a very thin layer of cirrus clouds overhead. Those cirrus clouds are made of ice. When the sun goes through the ice, the sunlight is refracted (bent) and can sometimes create either sun dogs or a 22° halo. This can also occur around the moon.

@NPR bungles sea level rise story

NPR logo
"Data from CO2 measuring stations and from the Sewell's Point and all other tide gages may clearly refute these assertions, but NPR and its colleagues will not change their minds."

"The Sewell's Point tide gage shows that the rate of sea level rise has not changed since the gage was installed in 1927, and is unchanged from our use of fossil fuels. It's time to base our policies on sound science, instead of manmade global warming fiction and scare stories."
National Public Radio's March 31 "Morning Edition" program carried a "news" story claiming that rising seas threaten a number of U.S. coastal military bases. The commentary was so laden with factual errors that listeners might have thought it was an early April fool's joke. Unfortunately, it was not.

NPR remains so wedded to its belief that humans and carbon dioxide emissions are causing a fossil fuels - driven global warming catastrophe that its reporting has been compromised, and it is unable to think critically or report honestly without resorting to activist claims and fake news events.

Real journalism would have at least included passing references to alternative views and sources. But they were absent in this story, which in truth is a splendid example of ignorance or deception—reader's choice.

Strange banging noises heard throughout Abergavenny, Wales

THINGS that go boom were heard throughout Abergavenny last weekend and as of yet there has been no official explanation as to what caused them.

The Chronicle has been inundated with queries as to the nature of the loud, fierce, and persistent. bangs were which left the town all shook up on the weekend.

As many natives were nursing the last vestiges of their hangovers and settling down to watch the Antique's Roadshow last Sunday evening, the town was collectively unnerved by the mother of all bangs.

One Abergavenny resident said, "It nearly gave me an heart attack it was that loud. A first I though it was shotgun blast or a firework, but it was way too loud for that. It sounded more like a tank going off. My husband said it was probably mini meteors colliding with the earth, but have you ever heard such nonsense?"

Actually we have. The meteor story is not as far-fetched as it sounds. When a massive meteor enter the atmosphere over a specific area it makes a very distinguishable noise. The scientific term for this is 'sonic boom'.

Magnitude 6.2 subduction zone earthquake strikes El Salvador

This Temblor map shows the location of today’s M=6.2 earthquake, as well as Global Earthquake Activity Rate (GEAR) model.
A M=6.2 earthquake struck off the coast of El Salvador at 4:41 a.m. local time this morning (12 May 2017). According to the USGS, the quake occurred at a depth of 10 km, approximately 75 km offshore. So far, no reports of damage have come in, and the USGS estimates that economic losses should remain minimal, and that there should be no fatalities as only light shaking was felt in the country, including in the capital city of San Salvador, which is home to over 250,000 people.

Even though the USGS does not have a focal mechanism, based on the earthquake's depth and location, it likely occurred on the Central American subduction zone or just above it. This analysis was also aided by using the Slab 1.0 model by Gavin Hayes at the USGS (which appears in Temblor as "Megathrust" zones). This model is a compilation of global subduction zones geometries. Based on the geometry of this subducting slab, it should be at a depth of 10-20 km in the location of today's event.

Waterfall at Yosemite National Park
Visitors to Yosemite National Park are getting quite the rare and spectacular show.

Thanks to record snowfall that is now melting in the mountains, hundreds of massive waterfalls, that have been dry for years, are once again flowing. Visitors are packing the park to catch a glimpse of the no-longer secret falls.

Park officials say the temporary falls should be active for at least a month.

Record-breaking snowstorm puts an end to California's 'super bloom'

A portion of California's recent super bloom was killed off last weekend after a rare spring snowstorm.
Part of the state's most prolific bloom since 1999 is now buried under 10 inches of snow.

A Southern California super bloom so prolific it could be seen from space has been killed off by a last gasp from old man winter.

While many of the spectacular species of wildflowers, from Arizona lupine to desert lilies, were already on the wane, a freak snowstorm that blew through the state on May 7 finished the job. In San Diego, the city recorded its coldest day in 64 years with a high of "only" 59 degrees. Nearby Palomar Mountain, where blooms were still heavy with color, recorded a record 10 inches of snowfall.

A rare May snowfall hit Norway's capital city overnight between Wednesday and Thursday, and, in some parts of the city, it was the first time in 50 years that there was that much snowfall.

In the Tryvann area north of Oslo, 40 cm of snow was registered, according to newspaper. Aftenposten

Snow also fell in Oslo's Blindern area, where the main campus of the University of Oslo is located.

"Snow was registered at Blindern in May only once before. It happened in 1967," meteorologist Terje Alsvik Walloe told Aftenposten.

On Wednesday, the thermometer did not go above 3.1 degrees in Blindern, marking the lowest temperature ever measured on the same date in Oslo.

Freak hailstorm hits Koolyanobbing, Western Australia

Koolyanobbing was hammered with hail on Thursday morning
The Wheatbelt mining town of Koolyanobbing has experienced a spectacular hail storm, transforming it into a wintry dreamscape.

Incredible photos of the aftermath of Thursday morning's storm have surfaced on Facebook, and show thick layers of ice on the ground in scenes more reminiscent of a ski field than the Australian outback.

Ronnie Canning, who posted the photos to facebook and has worked at the local iron ore mine for ten years, said he hadn't seen anything like it.

"It all happened pretty quick to tell you the truth, it escalated quite quickly. It all happened within about ten minutes, so it was quite loud and noisy really," Mr Canning said.

Dead minke whale found on beach in Alnmouth, UK

The minke whale.

The minke whale.
A dead minke whale has been washed up on a Northumberland beach.

The creature was discovered at Alnmouth yesterday. Experts have described it as being an incredibly underweight juvenile and about 4.25metres in length. The cause of death is unknown at this stage.

Jane Hardy, from Alnwick, is a volunteer marine mammal medic for British Divers Marine Life Rescue (BDMLR) and she arrived at the scene at just after 6pm.

She told the Gazette last night: "I am sad to say that I was called out to a minke whale on Alnmouth beach. It was first reported at 5.30pm. Amble Coastguards assisted the BDMLR and samples were being taken. It was dead when it breached, but the cause of death is unknown. It was an incredibly underweight juvenile.

"Coastguards were trying to organise to move it further up the beach so the next tide didn't take it."
