UK – The Met Office has issued a yellow weather warning after half a month’s worth of rain fell in 24 hours across the country. Forecasters said parts of the North West had seen 50mm of rain in 24 hours, with 52.2mm recorded between 11am on Saturday and 11am on Sunday at Greenfield near Oldham. Flooding and standing water has caused problems for commuters and residents across the affected areas. The wet weather comes after Britain was hit by record-breaking hot temperatures and thunderstorms, with the heatwave causing problems for train and air passengers.

Global Warming

Global Warming Is Pushing Pacific Salmon to the Brink

Pacific salmon that spawn in Western streams and rivers have been struggling for decades to survive water diversions, dams and logging. Now, global warming is pushing four important populations in California, Oregon and Idaho toward extinction, federal scientists warn in a new study.

The new research shows that several of the region’s salmon populations are now bumping into temperature limits, with those that spawn far inland after lengthy summer stream migrations and those that spend a lot of time in coastal habitats like river estuaries among the most at risk.

That includes Chinook salmon in California’s Central Valley and in the Columbia and Willamette River basins in Oregon; coho salmon in parts of Northern California and Oregon; and sockeye salmon that reach the Snake River Basin in Idaho, all of which are already on the federal endangered species list.

The salmon live much of their lives in the ocean, but they swim far upstream to spawn. In the process, they’re a key part of the food chain, including for bears and whales, and they are important to indigenous groups and fisheries along the U.S. West Coast.

The research spells out several ways that global warming endangers the fish. Among them:

– Young salmon die when the water warms above a certain threshold, and droughts can leave salmon stranded or exposed to predators by low water levels.

– Flooding can also flush eggs and young fish from their nests, so the scientists included projections of how global warming will affect extreme atmospheric river rain storms in California as one of the ways to measure the growing threat.

– Warmer stream temperatures have also increased outbreaks of fish disease that can affect salmon, including pathogenic parasites. In May, a toxic algae bloom along the coast of Norway killed 8 million farmed salmon at an estimated cost of about $82 million. In Alaska’s Yukon River, a parasite linked with global warming has taken a big toll on the salmon fishery. And in recent weeks, local indigenous observers in Alaska have posted numerous reports of dead salmon in rivers in the western part of the state, as water temperatures reached record highs during Alaska’s record-setting heat wave.

– Salmon are also sensitive to changes in ocean currents that carry nutrients, as well as sea level rise, which affects the physical connection between ocean and stream ecosystems, like coastal wetlands in California. Some salmon populations living near the edge of the range of suitable conditions will start to cluster in rivers near the coast, unable to reach their historic spawning grounds unless “access to higher-elevation habitats is restored and habitat quality in rearing areas and migration corridors is improved,” the scientists wrote.

Space Events

Delta Aquariid Meteor Shower

The dazzling Delta Aquariids 2019 meteor shower will be at its nominal peak tonight, July 29, and can be best spotted in the Southern Hemisphere.

What is essentially a display of space dust and bits of debris bursting from a comet (or comets) in our orbital path, the Delta Aquariids meteor shower will fly close to the Sun shedding particles that hit our atmosphere, around 60 miles above Earth. The meteor will zoom across the skies during which it will vapourize into shooting stars, leaving a trail of blazing light behind.

If at all you miss the celestial show tonight, you have until mid-August to catch the Delta Aquariid as the long, rambling meteor shower is officially active from July 12 to August 23 each year.

Wildfires

Wildfires – Montana, USA

At least three wildfires are burning in western Montana. The largest is the North Hills Fire north of Helena which has burned about 4 square miles (10.5 square kilometers) and prompted the evacuation of about 100 homes.

Disease

Dengue Fever – Tanzania

Since the dengue outbreak began in Tanzania one year ago, 6,677 cases have been reported, including 13 deaths. It appears that the outbreak is slowing as there were 536 cases of infection with the dengue virus in June, while only six cases have been reported since early July.
