Mozambique – The number of people killed after Cyclone Kenneth slammed into Mozambique has jumped from five to 38, the country’s disaster management institute said on Monday. Cyclone Kenneth made landfall on Mozambique’s northern coast on Thursday, packing storm surges and wind gusts of up to 280 kilometres per hour, stretching resources in a region still recovering from Cyclone Idai, which struck further south in March. Since then it has dumped heavy rain on the region, causing floods. Rains grounded aid flights in northern Mozambique for a second day on Monday, hampering efforts to reach survivors of Cyclone Kenneth. Rescuers managed to use a brief break in the downpours to send one helicopter packed with aid to the island of Ibo, where hundreds of homes were flattened by the second cyclone to hit the country in less than six weeks. But rains started again and conditions were too dangerous for the next flight to take off, the United Nations said. Roads to rural districts further north were swamped and impassable after torrential rains on Sunday.

Alaska’s Excelsior Glacier Is Being Replaced by a Lake 5 Times the Size of Central Park

Seventy years ago, Alaska’s Excelsior Glacier stretched its cold fingers from a vast plain in the state’s southern edge nearly all the way to the North Pacific Ocean. Now, the glacier is separated from the sea by a meltwater lake more than five times the size of New York City’s Central Park.

In a recent blog post on the American Geophysical Union (AGU) website, glaciologist Mauri Pelto of Nichols College in Massachusetts shows how that relatively new lake — now called Big Johnstone Lake — has more than doubled in size over the last 24 years as rising global temperatures force Excelsior Glacier into a hasty retreat. The glacier has lost about 30% of its length in just 24 years.

Even if no more calving ice makes its way into Big Johnston Lake, the glacier will continue to retreat, but probably at a slower pace than the rapid melting observed over the last 25 years. A similar fate has already befallen many neighboring glaciers in Alaska and British Columbia, Pelto wrote, providing yet more examples of how climate change is rapidly redrawing the map of our world.

Disease

Ebola – DR Congo

Democratic Republic of Congo registered a one-day record of 27 new confirmed Ebola cases on Sunday, raising last week’s number of cases to 126, the biggest since the current outbreak was declared last August, the health ministry said. The previous record was 110 confirmed cases a couple of weeks ago.

The outbreak in the country’s eastern regions is now spreading at its fastest rate, due largely to a spate of attacks by militiamen and others distrustful of the international response. In the past two months, five Ebola centers have been attacked and a senior World Health Organisation official was killed by militiamen 10 days ago.

Hepatitis A – Florida, USA

Florida health officials reported an additional 70 hepatitis A cases during the past week, bringing the number of cases in 2019 to 954 and more than 1500 cases since the beginning of last year.
