International / Hunga Tonga’s Water Vapor Remains Aloft
« Last post by Mark on July 19, 2026, 08:33:37 AM »
The Jan 2022 eruption of Hunga Tonga–Hunga Haʻapai injected 150 million metric tons of water vapor directly into the atmosphere, increasing the stratosphere’s total water burden by about 10%—the largest disturbance ever recorded.

Water vapor is the atmosphere’s most abundant greenhouse gas and the largest contributor to Earth’s natural greenhouse effect. In the lower atmosphere it largely acts as a feedback, rising and falling with temperature. Hunga Tonga propelled water directly into the stratosphere, where it can alter radiation, ozone chemistry and atmospheric circulation.

The disturbance is still present in July 2026.

Satellite observations show that by early 2025, around 75 million metric tons—approximately half the original excess—had been removed. The remainder is decaying with an estimated three-year e-folding time and is expected to return to the pre-Hunga range around 2030.

International / Polar Air Grips Brazil
« Last post by Mark on July 19, 2026, 08:30:29 AM »
A broad mass of polar air spread across Brazil’s South, Southeast and Center-West, reaching into southern Bahia.

The high country plunged to -11.5C (11.3F) on July 15 at the Campo Belo station in Parque Nacional do Itatiaia, but the cold reached well beyond the mountains.

Across the Southeast, Nova Friburgo dropped to 3.7C (38.7F)—about 6C below its average July minimum—and Campos do Jordão reached a similarly anomalous 2.1C (35.8F).

Farther east, Xerém fell to 11C (51.8F), and Rio de Janeiro’s Vila Militar reached 11.3C (52.3F)—some 4C below average.

This week, a myriad of low temperature records have fallen across Russia (and Kazakhstan)—including at Severnoye, Minusinsk, Nizhneudinsk, Omolon and Pavlodar.

Now Nizhneudinsk has done it again. The Irkutsk Oblast station fell to 4.2C (39.6F) on July 14, breaking the previous daily low of 5C (41F) set in 1961.

That followed its 3.9C (39F) reading just one day earlier, which beat the July 13 benchmark of 4.1C (39.4F) from 1957 and also ranks in Nizhneudinsk’s top 10 July lows in record books extending back to 1940.

The heat-obsessed media are looking elsewhere.

Greenland’s ice sheet is currently carrying far more surface snow and ice than normal.


Latest DMI data put accumulated surface mass balance near 590 billion tonnes—roughly 100 billion tonnes above the 1981–2010 mean for this point in the season. Despite summer melt well underway, 2026 remains near the top of the recent range.

And this is not a one-year blip.

Of the past nine seasons (plotted since 2018), six finished—or, in 2026’s case, are currently running—above average:

International / Siberian Chill Breaks 51-Year Record.
« Last post by Mark on July 19, 2026, 08:09:54 AM »
While weather coverage remains fixated on heat, a summer chill has spread across swaths of Russia.

Western Siberia has cooled sharply, with temperatures running well below normal across large parts of the region.

Nighttime temperatures are dipping to around 5C (41F), with cold air trailing behind a departing cyclone.

Severnoye, in Russia’s Novosibirsk Oblast, fell to 5.8C (42.4F) on July 12, beating the locale’s previous daily minimum of 7.2C (45F) set in 1975. The station (WMO 29418) holds records back to 1936.

International / The 2026 Australian snow season has hit its highest snow depth yet
« Last post by Mark on July 19, 2026, 08:07:27 AM »
The 2026 Australian snow season has hit its highest snow depth yet after last weekend’s snowfalls, with hydro-electric operator Snowy Hydro measuring a snowpack 70.8 cm deep at Spencers Creek, roughly halfway between the NSW ski resorts of Perisher and Thredbo.

But at slightly lower elevations in the mountains where you’d ordinarily expect at least a thin midwinter snow cover, there is currently no natural snow at all.

Huge snow depth difference across just a few hundred metres of elevation

Snowy Hydro has three sites where it has measured the snow depth at frequent intervals in the cooler months since 1954.

Spencers Creek is the highest, at 1830 metres above sea level. Three Mile Dam, near Selwyn Snow Resort in NSW, is the lowest at 1460 metres.

The contrast between the two could hardly be more stark at present. While Spencers Creek has 70.8 cm, Three Mile Dam has no measurable snow at all.
