The coming ice age - Antarctic peninsula has been cooling not warming

The "fastest warming place" on Planet Earth wasn't warming.

A new Antarctic study wipes out 20 years of panic about the West Antarctic Peninsula. All these years while people were crying about penguins, it turns out that the place was cooling rather than warming. Mankind has emitting a third of all its "CO2-pollution" ever from 1998, and there was "no discernible" effect on Antarctica. Indeed, the study quietly finds that even the bigger longer warming that has happened in the last century was not "unprecedented" in the last 2000 years.

In the last decade as this cooling trend was happening in the real world - in the media, the same spot was being described as "one of the fastest warming places on Earth":
The Antarctic Peninsula is one of the fastest-warming places on Earth, NBC, 2013

And this sort of news has been going on for years. This was "big deal" once-in-2000 year type stuff:
UK scientists say parts of Antarctica have recently been warming much faster than most of the rest of the Earth. They believe the warming is probably without parallel for nearly two thousand years. - BBC, 2001
But the news in 2016 was a bit of a bomb, prone to being misinterpreted, so the PR Team was pre-armed with excuses, from the first line of the scientific abstract which pretty much says that the peninsula still was one of the fastest warming places on Earth (if you look at warming from 1950 and ignore the last 20 years the study is studying). Great opening line. The abstract also mentions that the Antarctic peninsula is only 1% of the Antarctic (though no one seems to mention that when it was melting).

July snowfall strikes Northern N.W.T. communities in Canada

It might not quite feel like a Northern Christmas in July, but some people in parts of the N.W.T. certainly aren't welcoming the winter-like weather that's hit their communities.

This week, snow has been falling in at least three N.W.T. communities — Sachs Harbour, Inuvik and Paulatuk.

CBC Meteorologist Ashley Brauweiler says about five centimetres fell in Sachs Harbour between Tuesday and Wednesday, breaking a new record for July 20. The last record was hit in 1966 with just 3.3 centimetres of snow.

Brauweiler says conditions could continue into Thursday, with another two to three centimetres falling in Sachs Harbour.

She says it's all thanks to a low-pressure system that formed over the Beaufort Sea and is slowly moving east, including over Sachs Harbour.

Brazilian Arabica coffee crop suffers 36% loss from cold; 70% banana crop loss

Brazil suffering record cold temperatures again in July 2016 after a cold wave that damaged agriculture in June 2016.

Arabica coffee beans stand at 36% loss, bananas 70% loss in Ribeira, Argentina 30% loss of raisin production and Chile clementine 30% increase.

The grand solar minimum is here, South America is repeating the normal pattern expected climate wise during the GSM.

Two spots in Middle East hit with 129 degrees, hottest ever in Eastern Hemisphere

Temperatures simulated by the GFS model in the Middle East on Friday reached 129 degrees (54 Celsius).
The temperature in Mitribah, Kuwait, surged Thursday to a blistering 129.2 degrees (54 Celsius). And on Friday in Basra, Iraq, the mercury soared to 129.0 degrees (53.9 Celsius). If confirmed, these incredible measurements would represent the two hottest temperatures ever recorded in the Eastern Hemisphere, according to Weather Underground meteorologist Jeff Masters and weather historian Christopher Burt, who broke the news.

It's also possible that Mitribah's 129.2-degree reading matches the hottest ever reliably measured anywhere in the world. Both Mitribah and Basra's readings are likely the highest ever recorded outside of Death Valley, Calif.

Death Valley currently holds the record for the world's hottest temperature of 134.1 degrees (56.7 Celsius), set July 10, 1913. But Weather Underground's Burt does not believe it is a credible measurement: "[T]he record has been scrutinized perhaps more than any other in the United States," Burt wrote. "I don't have much more to add to the debate aside from my belief it is most likely not a valid reading when one looks at all the evidence."

If you discard the Death Valley record from 1913, the pair of 129.2-degree readings from Mitribah and Basra over the past two days would tie the world's highest known temperature, also observed in Death Valley on June 30, 2013, and in Tirat Tsvi, Israel, on June 22, 1942. But Masters says the Israeli measurement is controversial.

Basra, the city of 1.5 million about 75 miles northwest of the Persian Gulf, has registered historic heat on two straight days. On Thursday, it hit 128 degrees (53.6 Celsius), the highest temperature ever recorded in Iraq, which it then surpassed on Friday, rising to 129.

A potentially record-breaking 'heat dome' is coming in the US

A massive "heat dome" is heading for the U.S. that will bake much of the country to potentially record-breaking temperatures next week, the Washington Post reports.

Only the Pacific Northwest is expected to escape the heat wave, while the rest of the country can look forward to some of its "hottest weather with respect to normal," the Post's weather editor Jason Samenow writes.

Although it is too early to know exactly how hot it will get, temperatures in the central U.S. and Upper Midwest could reach 10 to 20 degrees above average. Highs in Des Moines, Iowa, for example, may surpass 100°F for three days straight.

Huge hailstorms damage thousands of houses in Brazil; 20 inches of ice on the streets

50 cm (20 inches) of ice accumulated on the streets

A strong hailstorm hit parts of Rio Grande do Sul on Wednesday night, damaging 2,563 buildings.

Some 50 cm (20 inches) of ice accumulated on the streets in northern parts of the city of Não-Me-Toque (lit. Don't-Touch-Me). The ice also felled trees on the ERS-142 between Carazinho and the city.

The mayors of Vale do Sinos, São Leopoldo and Novo Hamburgo declared an emergency.

The storm, which hit municipalities in the North, Northeast and Metropolitan and the Valleys of Taquari, Rio Pardo and Paranhana, was the second hail storm in the state in the week - Northern cities had already been punished by hail on Sunday night.

Fresh snow in the Alps!

Following a very warm start to July, temperatures have plummeted this week with fresh snow as low as 1600m in parts of the Alps this morning!

The heaviest snow has been in Austria (benefiting summer ski areas such as Hintertux and Mölltal), eastern Switzerland and parts of the central and eastern Italian Alps (e.g. Passo Stelvio), where as much as 30cm has fallen at high altitude with more forecast today.

Cold front brings July snow to Klamath, Oregon

An unseasonal cold snap brought snow to northern Klamath County Sunday with additional cold weather possibly arriving next weekend.

Areas such as Crescent and Crater Lake National Park saw between 2 and 3 inches of snow, while other parts of the region saw temperatures dip as low as the 30s.

Meteorologist Mike Petrucelli, of the National Weather Center's Medford office, said both cool and moist weather is abnormal for mid-July, but not impossible.

"It's not unheard of, but just unusual" said Petrucelli.

July snow in Western USA, Atlantic ice whirlpools and the 'Cold Blob' switches oceans

October like temps are expected across the western USA along with SNOW over the next week well into July. Interesting how the warmest year ever has snow in July. A unique ice whirlpool visible from space off the coast of eastern Canada. The "Cold Blob" has switched oceans and become hot, well at least in the media.
