Fire illuminates the remains of a burned-out property near Mariposa, Calif., on Tuesday.
A wildfire in the foothills near Yosemite National Park has consumed eight structures — and is threatening 1,500 more in tiny Mariposa, Calif.

The town's 2,000 residents have been ordered to evacuate because of the blaze known as the Detwiler Fire, and Gov. Jerry Brown has issued a state of emergency for Mariposa County.

The California Department of Forestry and Fire Protection, known as Cal Fire, posted on its website that "firefighters experienced extreme and aggressive fire behavior" on Tuesday. "Firefighters on the ground as well as aircraft are actively working to contain and suppress the fire."

The Detwiler Fire has burned more than 45,000 acres and is just 7 percent contained, and it threatens "culturally and historically sensitive areas," the agency says.

"I haven't seen these conditions in a long time, it's a wind driven, slope-driven, fuel-driven fire," Cal Fire's Jerry Fernandez told Fresno's ABC affiliate.

Mariposa is about 150 miles east of San Jose, Calif.

For us this is one of the most fascinating types of lightning, beyond rare, its so rare that many people disbelieve. We receive only 1-2 reports per year in Europe and this is the 2nd one we have seen in 2017.

Observed in Italy around 1:30AM in Bergamo 14th July during severe warned storms (STA) on map... immediately after the strong pulsing glow came a very strong smell of sulphur, a common trait with ball lightning reports.

No sign of fire the following morning and this occurred some 2-3 meters above the tree tops on a hillside in front of the observers home.

Rare snowfall filmed on Table Mountain, South Africa

It hardly ever snows on Cape Town's fabled Table Mountain, but when it does in the internet era, it's definitely going to get caught on tape.

The courtesy comes from YouTuber Justin Hawthorne, who this past weekend experienced the fluffy precipitation from near the summit of the mesa.

Snowfall began around midday on Sunday 16 July, and lasted for around two minutes, Hawthorne notes in a comment.

"There had been a few lighter flurries over 15min or so prior. There were only a few spots on Table Mountain with visible snow that I saw leading up to this, but it clearly showed that snow had fallen on Saturday night — but a little."

"It was just fantastic to have had some snow falling during the day, in good weather conditions - so it made for a great shot," he added.

A rare cloud 'phenomenon' was spotted over Bournemouth last week.

The rainbow coloured haze in the cloudy sky led a string of enquiries on social media.

And while many put the colourful sight down to cloud iridescence, some said it could also be a circumhorizontal arc. Cloud iridescence happens when light is diffracted by ice crystals in the clouds, producing a rainbow effect.

2017's natural catastrophes less damaging than 10-year average so far

Disasters inflicted a financial cost of around $41 billion in the first six months, Munich Re reported
Natural catastrophes worldwide were less devastating in the first half of 2017 than the average over the past 10 years, reinsurer Munich Re said Tuesday, while highlighting the role of climate change in severe US storms.

Some 3,200 people lost their lives to disasters between January and June, the German group found -- well short of the 10-year average of 47,000 for the period or the 5,100 deaths in the first half of 2016.

April floods and landslides in Colombia that claimed 329 lives were the deadliest single event.

Elsewhere, an April-June heatwave in India killed 264 people, while floods, landslides and avalanches claimed around 200 lives in Sri Lanka, 200 in Afghanistan and 200 Bangladesh.

Disasters inflicted a financial cost of around $41 billion in the first six months, Munich Re reported.

That was less than half of the $111 billion toll in the same period last year, or the average of $102 billion over the past 10 years.

Comment: Damage was way up in 2016, but the trend for the past few years seems to have been fewer major disasters, but with perhaps more frequent smaller-scale events:

An alligator bit a man swimming in the Peace River Sunday afternoon -- this is one of four attacks to have occurred in the past 10 days and the second attack in the area.

Russell Mendelsohn, 34, was bitten on his left foot while wading in the waters at Morgan Park in Arcadia.

One witness we spoke with told us he saw Mendelsohn playing in the water with his two daughters and then he heard him scream.

Justin Cassell watched on as he pulled his two daughters out of the water. When he got to the shore, it was clear Mendelsohn had been attacked by an alligator.
