China's Sichuan province has ordered all factories to shut down for six days to ease a power shortage in the region as a scorching heat wave sweeps across the country.

Sichuan is a key manufacturing location for the semiconductor and solar panel industries and the power rationing will hit factories belonging to some of the world's biggest electronics companies, including Apple (AAPL) supplier Foxconn and Intel (INTC).

The province is also China's lithium mining hub — a key component of electric car batteries — and the shutdown may push up the cost of the raw material, analysts said.

China is facing its fiercest heat wave in six decades, with temperatures crossing 40 degrees Celsius (104 degrees Fahrenheit) in dozens of cities. The extreme heat has caused a spike in demand for air conditioning in offices and homes, putting pressure on the power grid. The drought has also depleted river water levels, reducing the amount of electricity produced at hydropower plants.

It's been storming here at Cerro Catedral for the past 3-days.

Fierce storming at times with 1-inch diameter snowflakes - or clumps of snowflakes - coming down hard.

The mountain has been more or less closed for 3-days due to fierce winds and avalanche danger.

Somewhere around 3-4 feet of snow had already fallen by the time we awoke today.

It's even been snowing in town to the tune of around 6″ the past 2-days which, in general, is a rarity here.

Early this Saturday, August 13, low temperatures were recorded in different cities of the Sierra de Ecuador. The south of the capital and Latacunga were the coldest points.

Historically cold mornings were suffered in Ecuador over the weekend, particularly across the nation's Highlands.

Harsh frosts were noted as the merucy dipped below the freezing point.

The town of Latacunga, for example, plunged to to -3.8C (25F) — a new record-low for the month of August, and a reading only 0.9C from the national monthly low (the -4.7C (23.5F) set in Pisayambo).

Alaska receives first snow of season at Brooks Range and Denali National Park

After receiving the first winter storm warning out of anywhere in the U.S. this season, fresh snow has dumped on Alaska in its Brooks Range. It's the first snowfall of the season for a U.S. region and, even though it's in the far north of Alaska, new snow is new snow.

The last winter storm warning for the US was issued on June 15 in northern Montana. Although it's extremely unlikely that any part of the continental U.S. will get snow this month, August marks the last month of meteorological summer, meaning that meteorological autumn will kick off on Thursday, September 1. Not long after that, it'll be winter, and you know what that means.


France battles 'monster' wildfire as heatwaves scorch Europe

A "monster" wildfire raged for a third day in southwestern France on Thursday, ravaging forests and forcing 10,000 people to evacuate their homes.

With no let-up in scorching temperatures likely before the weekend, firefighters backed by water-bombing aircraft battled on many fronts, saying the massive fire could change direction at any moment.

"It's an ogre, it's a monster," Gregory Allione from the French firefighters body FNSPF told RTL radio.

Wildfires have broken out across Europe this summer as successive heatwaves bake the continent and renew focus on climate change risks to industry and livelihoods.

Valentine Dupy took photos of her house with her phone before being evacuated from Belin-Beliet, at the heart of the Gironde region "just in case something happens".


Intense European heatwave parches Loire Valley, France's 'garden'

There are warnings of a "disaster" in the Loire Valley, France, if it doesn't rain soon
The Loire Valley is known as "the Garden of France". But the garden is withering.

France's worst drought since records began has turned lush vegetation into arid fields of brown crops, shrivelling under what is now the fourth heatwave of the year.

In Vincent Favreau's vegetable farm, where he produces food for a hundred families in the area, the parched earth has stunted the growth of the cabbages. His potato plants are burnt out, producing just half the crop of a normal year.

Comment: Most of France on drought alert, farmers forced to reduce water use by 50% in some regions, harvest also threatened by recurrent heatwave


As Europe melts, southern Africa enjoys some rare snow nearly 8 inches deep

SNOWFALL confirmed
In sharp contrast to the heatwaves across Europe, people are skiing in Africa.

The tiny mountain kingdom of Lesotho, completely surrounded by South Africa, is the only country on earth where nowhere is fewer than a thousand metres above sea level.

While cold winters are not rare in much of southern Africa, snow is.

Inevitably, ski resorts are even rarer and at an altitude of 3,000 metres, Afriski in Lesotho's Maluti Mountains is Africa's only operating ski resort south of the equator.

Meka Lebohang Ejindu is a snowboard instructor there.

Comment: Another report - Snowfall between 5- 20cm confirmed in parts of South Africa.


Power grid shuts down as Iraq exceeds 51C in crippling heatwave

The rapid change has seen southern marshes in the southern in Dhi Qar province dry up, lining cracks for miles on end.

The rapid change has seen southern marshes in the southern in Dhi Qar province dry up, lining cracks for miles on end.
Iraq's power grid has been fried by extreme temperatures exceeding 51C, in a heatwave that's forced authorities to step in as millions swelter.

Millions were left without power on Saturday as the electricity grid failed in the southern provinces of Basra, Dhi Qar and Maysan.

Reports of mass food spoilage and illness have forced authorities to take measures to keep the population safe due to the "noticeable rise in temperatures".

Local reports say residents were battling the heat by driving around their city for the sole purpose of using the air conditioner.

On Sunday morning, the governor of Dhi Qar province announced a public holiday for state employees would be extended until the religious festival of Muharram begins on Tuesday.

France to "reduce or halt nuclear output" as heatwave restricts ability to cool plants

nuclear plant france
Forecast models indicate that high temperatures will persist across France in early August. Europe's second-largest economy has endured record-breaking heat this summer that has curbed nuclear power production. We detailed last month, "France Cuts Nuclear Power Generation Amid Record-Breaking Heatwave," and now, more reductions are planned amid an energy crisis.

Bloomberg reported French utility Electricite de France SA (EDF) said nuclear power stations on the Rhone and Garonne rivers will reduce power generation because a persistent heatwave is increasing water temperatures too hot to circulate through condensers and discharge back into waterways.
Under French rules, EDF must reduce or halt nuclear output when river temperatures reach certain thresholds to ensure the water used to cool the plants won't harm the environment when put back into waterways.

Restrictions have been in place at various times during the summer already. The latest warnings include curbs at the St. Alban plant from Saturday, according to a filing. The facility will operate at a minimum of 700 megawatts, compared with a total capacity of about 2,600 megawatts. Reductions are also likely at the Tricastin plant, where two units will maintain at least 400 megawatts. -Bloomberg

New surface stations report released - It's 'worse than we thought'


Official NOAA temperature stations produce corrupted data due to purposeful placement in man-made hot spots

Nationwide study follows up widespread corruption and heat biases found at NOAA stations in 2009, and the heat-bias distortion problem is even worse now

ARLINGTON HEIGHTS, IL (July 27, 2022) - A new study, Corrupted Climate Stations: The Official U.S. Surface Temperature Record Remains Fatally Flawed, finds approximately 96 percent of U.S. temperature stations used to measure climate change fail to meet what the National Oceanic and Atmospheric Administration (NOAA) considers to be "acceptable" and uncorrupted placement by its own published standards.

The report, published by The Heartland Institute, was compiled via satellite and in-person survey visits to NOAA weather stations that contribute to the "official" land temperature data in the United States. The research shows that 96% of these stations are corrupted by localized effects of urbanization - producing heat-bias because of their close proximity to asphalt, machinery, and other heat-producing, heat-trapping, or heat-accentuating objects. Placing temperature stations in such locations violates NOAA's own published standards (see section 3.1 at this link), and strongly undermines the legitimacy and the magnitude of the official consensus on long-term climate warming trends in the United States.

"With a 96 percent warm-bias in U.S. temperature measurements, it is impossible to use any statistical methods to derive an accurate climate trend for the U.S." said Heartland Institute Senior Fellow Anthony Watts, the director of the study. "Data from the stations that have not been corrupted by faulty placement show a rate of warming in the United States reduced by almost half compared to all stations."

NOAA's "Requirements and Standards for [National Weather Service] Climate Observations" instructs that temperature data instruments must be "over level terrain (earth or sod) typical of the area around the station and at least 100 feet from any extensive concrete or paved surface." And that "all attempts will be made to avoid areas where rough terrain or air drainage are proven to result in non-representative temperature data." This new report shows that instruction is regularly violated.
