Evidence says Summers are getting much cooler in the US - Climate scientists saying exact opposite

Every single metric shows that summer maximum temperatures are cooling in the US, and that heatwaves are becoming shorter, less intense and covering a smaller area.

Polar blast blamed for 2 deaths in Brazil

The polar blast affecting much of South America's Southern Cone has claimed its first mortal victims in Brazil, authorities said Wednesday.

A 45-year-old homeless man was found dead late Tuesday in Sao Paulo, Brazil's largest city, where the temperature climbed only to 10 C (50 F) - the coldest daily maximum in four years - before falling to 8.3 C (47 F) after sunset.

Sao Paulo's lowest temperature ever is 7.3 C (45 F), recorded on July 12, 1988.

The other fatality reported Wednesday was also a homeless man, a resident of Curitiba, capital of the southern state of Parana, who died amid overnight temperatures of minus 1.3 C (30 F).

The Sao Paulo municipal government said that despite an increase in the number of beds at homeless shelters to 11,800, the facilities were unable to accommodate everyone seeking to come in from the cold.

Around 20,000 people, including families with children, are sleeping on the streets of Sao Paulo, according to the Rev. Julio Lancelotti, coordinator of homeless outreach for Brazil's Catholic bishops conference.

A number of towns in southern Brazil experienced record low temperatures on Wednesday and some areas had snow and frost.

Bom Jardim da Serra, a town in the mountains of Santa Catarina state, posted an overnight low of minus 8.8. C (16 F).

The weather forecast calls for the unusually temperatures to hang on for one more day.

Comment: Elsewhere in South America this month extremely cold weather killed 2 people in Argentina and in Chile Santiago experienced snow for the first time in 20 years. See also:

Hottest day in 145 years for Shanghai, China

GFS model shows heat dome positioned over China.
The meteorological department of east China metropolis Shanghai recorded an air temperature of 40.9 degrees Celsius (105.6 degrees Fahrenheit) at around 2 p.m. Friday, the highest on record in the city in 145 years.

A red alert for high temperatures was issued by the Shanghai Central Meteorological Observatory on Friday.

The previous record high temperature in the city of 40.8 degrees Celsius was recorded on Aug. 7, 2013. A total of 13 high temperature red alerts have been issued since the new meteorological early warning system was adopted in 2007.

China has a three-tier early warning system for high temperatures: a yellow warning is issued when high temperatures above 35 degrees Celsius are predicted for three consecutive days, orange indicates a predicted high temperature of 37 degrees Celsius in the next 24 hours, and a red alert is issued when the temperature is forecast to reach 40 degrees Celsius within 24 hours.

Heat waves have hit the city since the beginning of summer and are expected to linger until the end of July.

Mysterious plumes of steam rising from Greenland glacier

Plumes of steam rising from cracks in a glacier near Kulusuk, Greenland.
The photo above was taken by pilot Ágúst Arnbjörnsson on July 11, 2017 during a flight from Keflavik to Portland, from a height of approximately 34,000 feet. The location is 75 km from Kulusuk in Greenland.

The image appears to show three plumes of steam rising from cracks in the glacier, which according to the blog of volcanologist Haraldur Sigurðsson, is 1.5 to 2 kilometers thick. This may be a sign of powerful geothermal activity from below.

Earlier this year a team of NASA researchers observed an ominous crack growing in the Petermann Glacier along the northern coast of Greenland.

Recently Greenland recorded the coldest temperature ever in the northern hemisphere for July.


Is our Sun slowing down?

The spotless Sun of July 21, 2017.
The Sun, now halfway through its life, might be slowing its magnetic activity, researchers say, which could lead to permanent changes in the sunspots and auroras we see.

The Sun has changed its figure, researchers say, and might keep it that way.

The structure of the Sun's surface, where sunspots live, appears to have changed markedly 23 years ago. That's when solar magnetic activity might have started slowing down, Rachel Howe (University of Birmingham, UK, and Aarhaus University, Denmark) and collaborators speculate in paper to appear in the Monthly Notices of the Royal Astronomical Society (full text here). Such a structural change might help explain the Sun's mysteriously weak cycles in recent years.

The interior of the Sun pulsates as rhythmically as a human heart. But while the heart pulses at one fairly steady frequency, the Sun reverberates at thousands of different frequencies.

Pressure changes inside the Sun create these reverberations, just like pressure changes in the air create sound. The sound waves inside the Sun are outside the range of human hearing - they're too low frequency - but if we sped them up, we could hear them just like any other sound.


Cold sweeps the Southern Hemisphere, major crop damage

Record cold engulfs South America decimating crops and leaving a wake of frost destruction and hundreds of thousands with out power. All the while main stream media touts a few degrees over normal in NYC. They forgot absolute anomalous cold and frost event that crossed the entire continent of South America. It was -8C in areas where average temperatures for this time of year are 17C. Crop losses are in the same areas as cold damage to agriculture last year. The 2017 losses will be tallied over the next weeks and it looks at early estimations of nearly 100% losses for fruit inn Southern Brazil, Argentina, Paraguay and Uruguay. Where is the coverage on this in the main stream media?????????

Green cronyism gone wild: It looks like the State of California is bailing out Tesla

© Twitter
The California state Assembly passed a $3-billion subsidy program for electric vehicles, dwarfing the existing program. The bill is now in the state Senate. If passed, it will head to Governor Jerry Brown, who has not yet indicated if he'd sign what is ostensibly an effort to put EV sales into high gear, but below the surface appears to be a Tesla bailout.

Tesla will soon hit the limit of the federal tax rebates, which are good for the first 200,000 EVs sold in the US per manufacturer beginning in December 2009 (IRS explanation). In the second quarter after the manufacturer hits the limit, the subsidy gets cut in half, from $7,500 to $3,750; two quarters later, it gets cut to $1,875. Two quarters later, it goes to zero.

Given Tesla's ambitious US sales forecast for its Model 3, it will hit the 200,000 vehicle limit in 2018, after which the phase-out begins. A year later, the subsidies are gone. Losing a $7,500 subsidy on a $35,000 car is a huge deal. No other EV manufacturer is anywhere near their 200,000 limit. Their customers are going to benefit from the subsidy; Tesla buyers won't.

This could crush Tesla sales. Many car buyers are sensitive to these subsidies. For example, after Hong Kong rescinded a tax break for EVs effective in April, Tesla sales in April dropped to zero. The good people of Hong Kong will likely start buying Teslas again, but it shows that subsidies have a devastating impact when they're pulled.

That's what Tesla is facing next year in the US.

In California, the largest EV market in the US, 2.7% of new vehicles sold in the first quarter were EVs, up from 0.4% in 2012, according to the California New Dealers Association. California is Tesla's largest market. Something big needs to be done to help the Bay Area company, which has lost money every single year of its ten years of existence. And taxpayers are going to be shanghaied into doing it.

To make this more palatable, you have to dress this up as something where others benefit too, though the biggest beneficiary would be Tesla because these California subsidies would replace the federal subsidies when they're phased out.

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.
