Finland says the low concentrations of radioactive material found in air samples pose no danger.

Air quality sinks to hazardous levels as biggest cloud seen in a generation swamps region after transatlantic journey

Abnormally warm weather will be established in the north of the Asian part of the country: in Yakutia, Chukotka and Krasnoyarsk region. In these regions, the temperature will reach 30 degrees Celsius.

The temperature in Verkhoyansk hit 38 degrees Celsius on Saturday, according to Pogoda i Klimat, a website that compiles Russian meteorological data.

Elevated pollen levels in Anchorage and across Alaska raise questions about changes in respiratory health and the importance of having good air quality during the coronavirus pandemic.

Seeing pollen in rainwater is unusual.

Several trains have been delayed and canceled due to the storm.

This time weather experts think the blackout was caused by smoke from wildfires mixing with heavy rain clouds.

An unseasonable rain event brought high rainfall and led to high water, especially around noon on August 3rd.

Weather watchers are focused on the world's most northerly community, which is in the middle of a record-breaking heat wave.

Thunderstorms are unusual in Unalakleet; however, a thunderstorm cell persisted in the area for longer than usual. Hot, dry conditions across Alaska have increased the risk of wildland fire, including that started from lightening strike.

Local residents debated whether a massive release of spruce pollen, which accumulated on every surface—including car bonnets, picnic tables and the nearby Kachemak Bay—amounted to a “golden sheen” or a “yellow scum”. The fine dust turned the surface of the sea the colour of butter and left a bright, lemony line on shore that marked the extent of high tide and gave off a sickly sweet smell. This huge release of pollen might be yet another symptom of a rapidly changing environment.

Unusual cone clouds in the air likely produced precipitation that evaporated before reaching the ground, due to unusually warm conditions.

A four-day heatwave across western Europe that killed seven people began to ease slightly on Sunday, as temperature alerts were cut back and wildfires slowly brought under control.

Little to no apparent management posed possible ecological and environmental health concerns.

On Wednesday, a new precipitation record was measured in Oslo with 22 millimeters in 10 minutes. "We had expected rain showers, but not that it would be so heavy," says state meteorologist.

Smoke from the North River fire is impacting outdoor air quality. The ADEC Division of Air Quality has issued an air quality advisory in effect from Tuesday, June 18, 2019 8:00 AM to Friday June 21, 2019 4:00 PM.

Smoke from the South River Hills Fire could be seen from Unalakleet. The fire began approximately 6 miles from the community, and grew from 30 to 160 acres.It was contained by BLM Alaska Fire Service Smokejumers by 11pm on June 9, 2019.

Seija Paasonen has been tracking the patterns of the North American forest fires for several weeks now. She says that the smoke has traveled as far as Europe owing to wind patterns in the upper atmosphere.
