India, Bangladesh – Tropical Cyclone Amphan, the most powerful cyclone to strike eastern India and Bangladesh in over a decade killed at least 82 people, officials said, as rescue teams scoured devastated coastal villages on Thursday, hampered by torn down power lines and widespread flooding. Mass evacuations before Cyclone Amphan made landfall undoubtedly saved countless lives, but the full extent of the casualties and damage will only be known once communications are restored, officials said. In the Indian state of West Bengal, Chief Minister Mamata Banerjee said at least 72 people had perished – most of them either electrocuted or killed by trees uprooted by winds gusting up to 185km/h (115 mph). She said the storm had carved a 400-km long swathe through the state. In neighbouring Bangladesh, the initial death toll was put at 10. When the cyclone barrelled in from the Bay of Bengal on Wednesday, a storm surge of around five metres caused flooding across low-lying coastal areas. Villagers could be seen trying to lift fallen electricity poles, fishermen hauling their boats out of a choppy sea, and uprooted trees lying strewn across the countryside. Designated a super cyclone, Amphan weakened after making landfall. Moving inland through Bangladesh, it was downgraded to a cyclonic storm by the Indian weather office, and it has since subsided into a depression.

Global Warming

Carbon Comeback

While overall global CO2 emissions have been expected to fall by about 7% this year due to the pandemic, scientists fear that the man-made pollution will rebound as the world’s population returns to work and industrial production surges.

Daily global emissions of the greenhouse gas fell by 17% at the height of the COVID-19 shutdown. But levels of transportation and economic activity are able to return to pre-pandemic levels by mid-June, researchers estimate the annual fall in CO2 emissions this year will be only 4%.

Wildlife

Cicadas Return – After 17 Years

The drone of untold millions of singing insects will soon echo across parts of the eastern United States from a group of cicadas that emerges from the ground only once every 17 years.

The mating songs of brood IX are among the noisiest of their kind. Their habitat stretches from North Carolina to West Virginia, where as many as 1.5 million can surface per acre.

Cicadas are large, clear-winged insects with bulbous eyes that emerge every year or in cycles of 13 or 17 years. They then shed and leave their brown husks behind on trees and other objects. After breeding, their nymphs crawl into the ground for a 17-year slumber.

Environment

Global Temperature Extremes

The week’s hottest temperature was 117 degrees Fahrenheit (47.2 degrees Celsius) in Nawabshah, Pakistan.

The week’s coldest temperature was minus 96.0 degrees Fahrenheit (minus 71.1 degrees Celsius) at Vostok, Antarctica.

Temperatures were tabulated from the more than 10,000 worldwide synoptic weather stations. The United Nations World Meteorological Organization sets the standards for weather observations, and provides a global telecommunications circuit for data distribution.

Dengue Fever & Covid-19 – Brazil

The number of dengue fever cases reported in Brazil through May 8 has come close to the one million mark (946,852 total cases, about half laboratory confirmed), including 298 deaths.

Brazil’s Ministry of Health reported some 18,000 coronavirus disease 2019 cases in the past 24 hours, putting the rapidly rising epidemic total to 310,087, third in the world.

Covid-19 – China

In Shulan, a city in China’s northeast, the streets are eerily quiet, devoid of taxis and buses. Apartment complexes have been sealed off, confining residents inside. Teams of government workers go door to door rounding up sick people as part of what they call a “wartime” campaign. As the Chinese authorities confront scattered outbreaks of the coronavirus in the country’s northeast, they are turning to many of the same strict lockdown measures that were a hallmark of the effort four months ago to stamp out the epidemic in the central city of Wuhan.

Foot and Mouth Disease – Kenya

Alarm has been raised in Murang’a County following an outbreak of foot and mouth disease in parts of Maragua division. In Ichagaki and Nginda locations, ten cows have died with several others displaying symptoms related to the disease. The disease spread through movement of animals from one village to the other, as well as people visiting cow sheds, the local county government says.

Volcanos

Roundup of Global Volcanic Activity – Ongoing Activity for the Week 13 May 2020 – 19 May 2020

Aira | Kyushu (Japan) : JMA reported that during 11-18 May incandescence from Minamidake Crater (at Aira Caldera’s Sakurajima volcano) was visible nightly. There were 10 explosive events with plumes rising as high as 2 km above the crater rim. Material was ejected 600-900 m away from the crater. The Alert Level remained at 3 (on a 5-level scale).

Asosan | Kyushu (Japan) : JMA reported that eruptive activity at Asosan was recorded during 11-18 May. Volcanic plumes rose 600-1,000 m above the crater rim and caused ashfall in areas downwind. The sulfur dioxide emission rate was high; the rate was 1,300 tons per day on 17 May. The Alert Level remained at 2 (on a scale of 1-5).

Dukono | Halmahera (Indonesia) : Based on satellite and wind model data, the Darwin VAAC reported that during 13-19 May ash plumes from Dukono rose to 1.5-2.1 km (5,000-7,000 ft) a.s.l. and drifted in multiple directions. The Alert Level remained at 2 (on a scale of 1-4), and the public was warned to remain outside of the 2-km exclusion zone.

Ebeko | Paramushir Island (Russia) : Volcanologists in Severo-Kurilsk (Paramushir Island), about 7 km E of Ebeko, observed explosions during 8-15 May that sent ash plumes up to 4 km (13,100 ft) a.s.l. Ash plumes drifted E, causing ashfall in Severo-Kurilsk during 8-12 May. A thermal anomaly was identified in satellite data during 12-14 May.
