Beetles, fungus and old age: The days of LA's palm trees are numbered

© Danita Delimont/Getty Images/Gallo Images‘The iconic association of palm trees with Los Angeles is a positive, but we’re now in a period where we have a better understanding of what’s needed,’ says a climate expert.
They are the sultry, swaying backdrop to countless films, posters and music videos, an effective way to announce: this is Los Angeles.

Palm trees greet you outside the LAX airport, they line Hollywood Boulevard, stand guard over the Pacific and crisscross neighbourhoods poor and rich, a botanical army of stems and fronds which symbolise the world's entertainment capital.

Apparently not for much longer. LA's palm trees are dying. And most won't be replaced.

A beetle known as the South American palm weevil and a fungus called Fusarium are killing palm trees across southern California. Others are dying of old age. "It'll change the overall aesthetic because palm trees are so distinctive. It's the look and feel of Los Angeles," said Carol Bornstein, director of the nature gardens at the Natural History Museum of Los Angeles.

A city tally in 1990 estimated the number of palms on city streets at 75,000, a number which has not been updated but is destined to plunge in coming decades, the Los Angeles Times reported this week, citing officials.

No one knows how many will die, or how fast. For palm lovers, the even worse news is that they won't be replaced, perhaps not even mourned.

Britannia Yacht Club recorded wind gust of about 160 km/h at 3:08 p.m. Wednesday


A rapidly moving column of sinking air called a microburst is likely to blame for the damage caused when a powerful storm moved through the National Capital Region Wednesday afternoon, Environment Canada says.

The Britannia Yacht Club on the Ottawa River recorded a wind gust of about 160 km/h at 3:08 p.m. Wednesday, the weather agency said in a French-language notice posted on its website Friday. Staff at the club confirmed the reading to CBC Thursday.

Winds moving that fast are consistent with F1 tornadoes, but microbursts can also cause winds at speeds of more than 100 km/h.

Damage was spread over an area stretching about seven kilometres, Environment Canada said, adding that the data contained in its notice is preliminary and doesn't constitute a final report.

Volcanic eruptions to cool Earth, record Arctic sea ice growth occurring

Mount Sinabung unexpectedly erupted, sparking fears over an imminent Mount Agung eruption in Bali
Mount Sinabung unexpectedly erupted, sparking fears over an imminent Mount Agung eruption in Bali

Vanuatu evacuates an island due to volcanic eruption, Bali evacuates villages due to volcanic eruption, Sinabung erupts, but what they dont tell you is that every Grand Solar Minimum there are massive eruptions that destroy global crop production. Now with record Arctic sea ice growth in 2017, the most ever recorded in September, the global warming crowd is just hoping for an eruption so they can blame Earths cooling temperatures on the volcano, not the Sun, which is the true driver of our climate.

Another whale shark found dead, the latest in Gujarat, India

whale shark
After a 30-feet long whale was found dead last week, body of a male whale shark, about 15 feet long, was found at Madhavpur coast on September 28.

A team of ICAR-Central Marine Fisheries Research Institute (CMFRI) and Wildlife Trust of India (WTI), Veraval, reached the spot to assess the reasons for its death.

Tarachand Kumawat, a scientist with Marine Bio-diversity in Veraval, said that there was a cut on the body which was probably due to a fishing propeller. "We are yet to finalize the reasons for its death. The dead shark was a sub-adult whale shark."

A whale shark, that was tagged in Gujarat, has covered a distance of about 5,500km since it was tagged. The shark has moved from Sutrapada towards the coast of Somalia, It now seems to be circling back to the Gujarat coast.

The migratory path of a female whale shark had been satellite-tagged off the Saurashtra coast in December 2016 under the Whale Shark Conservation Project run by the WTI and the Gujarat forest department.

61-year-old woman killed by pit bull terrier in Gilmer County, Georgia

PIT BULL ATTACK
A woman died after she was attacked by a pit bull on Thursday.

Gilmer County police said Kathy Sue Nichelson, 61, was attacked shortly after she arrived at a home on Goose Island Road.

A bystander saw Nichelson on the ground and stopped to help her. The dog then attacked the bystander before he escaped to his vehicle to call 911. He did not sustain any life-threatening injuries.

Police and emergency crews arrived and attempted to keep the animal away while EMS tried to treat Nichelson. Authorities said the dog came towards public safety personnel aggressively, and the animal was put down by deputies.


Authorities said the investigation into the animal's behavior and its owner are ongoing.


Comment: Other severe attacks recently reported are of a woman in hospital after being mauled by a pit bull in Blackfoot, Idaho and of another woman savaged by 3 dogs in Peru, New York.

A huge 'alien ship' shaped cloud formed over the city of Maracaibo in Venezuela on Monday, September 25 prompting social networks like Twitter to go viral with announcements of the 'end of the world', as reported in Perú.com.

The article went on to explain that the phenomenon was caused by cloud iridescence (also called "fire rainbows" or "rainbow clouds"), whereby the sun's light is refracted by water droplets and ice crystals in the cloud. An iridescent cumulonimbus cloud was seen over Singapore in April this year.

Arkansas State University assistant herpetology professor Lori Neuman-Lee isn't scared of reptiles — but she never thought she'd be studying two-headed ones.

Since she joined the faculty about a month ago, her lab has become home to a snake and a turtle found in Arkansas that have four heads between them.

On Sept. 6, an electric worker found a two-headed rattlesnake outside a home on Arkansas 248. The snake was brought to Forrest L. Wood Crowley's Ridge Nature Center in Jonesboro, then given to Neuman-Lee.

When Neuman-Lee went to pick up the snake Sept. 8, she said, facility director Shaun Merrell asked if she was interested in another reptile— a two-headed snapping turtle found on a farm near Little Rock.

"I said, 'Sure,'" she said with a laugh. The turtle was in her lab less than a week later.

Mexico's Popocatépetl volcano erupts same day as deadly quake

As if the deadly earthquake in Mexico weren't enough, a volcano erupted amid the violent tremors.

Popocatepetl - about 45 miles southeast of quake-ravaged Mexico City and some 30 miles from the temblor's epicenter - belched ash and gas as the 7.1-magnitude earthquake rocked the country's central region.

The county's volcano-monitoring system registered one explosion and 256 "low-intensity exhalations" between Tuesday and Wednesday mornings but said none of the activity can be attributed to the earthquake, according to Mexico's National Center for Prevention of Disasters.

A church in Atzitzihuacan at the foot of the mountain collapsed during the quake and eruption, killing 15 worshippers as they celebrated Mass inside.

Pope Francis said he was praying for victims in the majority-Catholic country.

"In this moment of pain, I want to express my closeness and prayers to all the beloved Mexican people," he said.

The 17,700-foot Popocatepetl has been particularly active this summer and also blew its top amid the Aug. 21 solar eclipse.

Comment: Meanwhile Bali's Mount Agung threatens to erupt for the first time in 50 years. Mount Agung is one of many similar volcanoes in Indonesia and the Ring of Fire surrounding the Pacific and eastern Indian oceans.

Cooling effect expected when Indonesia's Mount Agung erupts

Something very interesting will happen when Bali's Mount Agung finally erupts: the Earth will become a little bit cooler.

Yep. It's not exactly what you'd expect after a volcanic eruption, which will see molten lava spewed into the air.

But don't get too excited, it will far from reverse the effects of global warming.

Here's why:

Global temperatures dropped last time Agung erupted

Mount Agung last erupted in 1963 after lying dormant for decades.

When it erupted, experts said global atmospheric temperatures dropped by 0.1-0.4 degrees Celsius.
