Washington, USA – Wednesday carried in Snohomish County’s first round of seasonal flooding, swelling the Stillaguamish River in Arlington and Silvana. Landslides are possible.

Ireland – Heavy rain caused flash flooding and road closures across the country on Wednesday. The heaviest rain fell in the Dublin region, with 47.4mm of rain falling in Dublin airport up to 3pm, 8.4mm of that falling between 7am and 8am. Two housing estates in Mountmellick, Co Laois were evacuated when the Owenass river burst its banks, flooding access roads.

UK – Dozens of roads have been closed and rail services suspended as parts of Britain are battered by torrential rain and 80mph winds. Dozens of people have been rescued from “major flooding” amid warnings for heavy rain, strong winds and snow. Forecasters have also warned “some delays to road, rail, air and ferry transport are likely”. Families had to be evacuated in Lancashire after more than 4cm of rain fell in 24 hours. Further north in Cumbria, around half a month’s rain – almost 9cm – was recorded in 36 hours. Flooding forced motorists to abandon their vehicles as roads and schools were closed.

Environment

The difference between night and day is disappearing

The distinction between day and night is disappearing in the most heavily populated regions of the Earth, a rapid shift with profound consequences for human health and the environment, according to a paper published Wednesday in the journal Science Advances.

From 2012 to 2016, the artificially lit area of the Earth’s surface grew by 2.2 percent per year. Bright nighttime lighting only started becoming widespread about 100 years ago, meaning we have little idea how humans or other species adapt to it at an evolutionary level. Light has been introduced in places, times and intensities at which it does not naturally occur and [for] many organisms, there is no chance to adapt to this new stressor.

The past few years have seen the rapid adoption of highly efficient LED lights for indoor and outdoor use. The short-wavelength blue light emitted by most LEDs, because our eyes are particularly attuned to this type of light, it’s been implicated in sleep deficiencies and other human health problems. Last year, the American Medical Association issued a warning about health risks associated with this type of light.

California birds nesting earlier to try to survive global warming

The early bird not only gets the worm, but may stand a better chance of riding out global warming.

A new study finds that birds in California are breeding up to 12 days earlier than they did a century ago, an apparent effort to maintain their optimal nesting temperatures as the planet warms.

The study of 202 species of California birds found that by nesting five to 12 days earlier in the year, birds are breeding at the same temperatures they did 75 to 100 years ago. Although other researchers have noted earlier nesting times, they theorized that birds were making the changes to when food was available — and that with spring coming earlier, insects and seeds were in greater supply earlier.

The study concludes that birds are moving up their nesting schedules to time the births of chicks with the temperatures they need to survive.

Disease

Kentucky, USA – Hepatitis A

Kentucky has become the latest in an ever growing list of states battling a hepatitis A outbreak–following California, Michigan and Utah. On Tuesday, The Kentucky Department for Public Health (DPH) declared an outbreak of acute hepatitis A with cases in multiple counties in Kentucky. In total, 31 cases of acute (rapid onset with symptoms of illness) Hepatitis A have been reported throughout Kentucky in 2017.

Nigeria monkeypox update

Nigerian health officials have confirmed four additional monkeypox cases since our last report earlier this month, bringing the total cases in the outbreak to 42.

Volcanos

Roundup of Global Volcanic Activity – New Activity for the week of15 November – 21 November 2017

Agung | Bali (Indonesia) : PVMBG reported that a phreatic eruption at Agung began at 1705 on 21 November, following a low-frequency tremor signal. An ash plume rose 700 m above the crater rim and drifted ESE. The Alert Level remained at 3 (on a scale of 1-4), and the exclusion zones remained intact (at 6 km, and an additional expansion to 7.5 km in the NNE, SE, S, and SW directions).

Oraefajokull | Iceland : The Icelandic Meteorological Office (IMO) reported that on 17 November the Aviation colour Code for Öræfajökull was raised to Yellow because satellite images and photos showed that a new ice cauldron had formed within the caldera the previous week. The new cauldron was about 1 km in diameter and 15-20 m deep, and signified a recent increase in geothermal activity. Scientists conducted an overflight on 18 November; in addition, while on the ground, they took water samples, measurements of electrical conductivity, and gas levels at the Kvíárjökull outlet-glacier, a valley glacier on the SE flank of Öræfajökull. There was no obvious sign of flooding in the Kvíá river. A sulfur odor, which had been reported for about a week, was also noted. An increase in the seismic activity was recorded for the last few months (the largest earthquake, an M 3.4, occurred on the 3 October), but was low for the past few days. IMO noted that there were no signs of an imminent volcanic eruption, though there was considerable uncertainty about how the situation will evolve.

Sarychev Peak | Matua Island (Russia) : SVERT reported that weak steam-and-gas emissions from Sarychev Peak were observed on 13 November. Weather clouds prevented observations during 14-20 November. The Aviation colour Code remained at Green.
