Lao People’s Democratic Republic – Due to the monsoon season and heavy rainfall resulting from Tropical Storm Son-Tinh passing over Northern, Central and Southern Laos PDR between 18-19 July 2018, flooding occurred in 10 provinces: Attapeu, Savanhnakhet, Khammouan, Xayabuly, Bolikhamsay, Luang Prabang, Bokeo, Sekong, Xiengkhouang, Oudomxay. Due to the heavy rainfall, there was an overflow from Xepien-Xenamnoyu dam which resulted in flooding affecting downstream villages and more than 1,000 families were evacuated. The Xenamnoy dam in Attapeu province, 550 kilometres south of the capital Vientiane, was reportedly built to hold 1 billion tons of water, and is 1.6 kilometres wide. A volunteer emergency organisation, Vientiane Rescue, said the dam wall broke on Monday night after heavy monsoonal rains. Reports on one media site said millions of tons of water had inundated surrounding land, washing away villages and homes. More than 6,600 people were made homeless. Hundreds of people are missing and the death toll is as yet unknown.
Geese Fly to Exhaustion in Race Against Climate Change
Every spring, thousands of barnacle geese make a grand migration from their temperate winter habitat in northern Europe and northwestern Russia to their summer nesting grounds in the Arctic. It’s a journey of more than 1,800 miles (3,000 kilometers) that usually takes about a month, but new research has found that rising temperatures in the Arctic are pressuring the geese to make the trip in a grueling one-week sprint.
Barnacle geese (Branta leucopsis) are medium-size water birds found in Europe, Russia, the United Kingdom, Wales and the Arctic. Until recent years, the timing of the birds’ spring migration meant they arrived in the Arctic right as the snowmelt exposed their nesting sites and initiated plant growth. The birds would almost immediately lay their eggs, which would then hatch 30 or so days later, right at the peak season for plant growth — perfect timing for hungry, growing goslings.
But in the past few decades, scientists noticed that things have changed. Temperatures in the Arctic have been getting warmer earlier and earlier in the season — by about a day per year — and this is putting significant pressure on the migrating barnacle geese.
The geese are trying to keep up with these environmental changes, but they’re struggling. Scientists have found that the geese still leave at about the same time every year, but the animals have shortened their travel time to the Arctic. A trip that used to take about a month now takes the geese only about a week, as the birds will spend less time at their stopover sites or will skip them altogether and just keep flying.
Instead of promptly laying their eggs as they usually do when they arrive at their Arctic nesting grounds, the exhausted geese need more than a week to recuperate and build up enough energy before they can start nesting. By the time the animals are ready to lay their eggs, the grasses and plants the birds feed on have been growing for a few weeks. As a result, goslings emerge from their eggs after the peak growing season rather than during it, and that’s causing the young birds’ survival rate to decline.
Wildfires – Greece – Update
The death toll has risen to 74. Hundreds of firefighters have been battling the flames, which have been fanned by winds of up to 60mph (100km/h) and have devastated the seaside village of Mati, engulfing homes and vehicles. Scores of people rushed into the sea to escape the flames.
