USA – Two people have died in western Texas as a result of heavy rain and flooding in the region that began 27 June 2021. Flooding was also reported in neighbouring Chihuahua state of Mexico, where at least 5 people had to be rescued.

USA – Flash floods struck parts of the state of New Mexico after more than 5 inches of rain (127 mm) fell in 24 hours. Levels of the Pecos River and Dark Canyon jumped, causing flooding in areas around Carlsbad and Eddy County on 29 June 2021. Almost 30 roadways were closed as a result. Eddy County officials said residents living near the Tansill Dam and Reservoir were evacuating. The Carlsbad Caverns National Park has been closed due to flooding.

Enormous Antarctic lake vanishes in 3 days

An enormous, ice-covered lake in Antarctica vanished suddenly, and scientists are worried it could happen again.

In this disappearing act, which researchers say occurred during the 2019-2020 winter on the Amery Ice Shelf in East Antarctica, an estimated 21 billion to 26 billion cubic feet (600 million to 750 million cubic meters) of water — roughly twice the volume of San Diego Bay — drained into the ocean.

The scientists who used satellite observations to capture the shocking vanishing act say the lake drained in roughly three days after the ice shelf beneath it gave way.

“We believe the weight of water accumulated in this deep lake opened a fissure in the ice shelf beneath the lake, a process known as hydrofracture, causing the water to drain away to the ocean below,” Roland Warner, a glaciologist at the University of Tasmania.

Hydrofracturing leaves behind a gigantic fissure which compromises the structural integrity of the sheet as a whole. As meltwater lakes and streams multiply across the surface of Antarctica, researchers are concerned that growing volumes of surface meltwater could cause more hydrofracturing events, thus elevating sea levels above current projections.

Visceral Leishmaniasis – Chad

According to the World Health Organization (WHO), Visceral Leishmaniasis (VL) is endemic in some areas of Chad. Sporadic cases of leishmaniasis have been reported in Chad since 2018. Since 1 January 2018 to 31 May 2021, a total 122 cases of VL and six fatalities have been reported by three provinces.
