Brazil – At least nine people died after a cyclone swept through parts of southern Brazil on 30 June. Winds of over 120 km/h were reported in the state of Santa Catarina. The states of Rio Grande do Sul and Paraná were also badly affected. The wild weather has also brought the threat of flooding. Storm surge has prompted warnings for coastal flooding in Santa Catarina. In Rio Grande do Sul, river levels are above flood stage in some areas of after the storm brought rain of over 140mm in 24 hours. Almost 50 cities or municipalities in Santa Catarina state were affected by the cyclone.

Yunnan, China – At least 3 people have died in flash flooding in Yunnan Province, southwest China. Heavy rain from 29 June caused flash flooding in the city of Zhaotong and the counties of Zhenxiong, Yiliang, Weixin and Yanjin. Rainfall of over 225 mm in 24 hours was reported in the area.

Global Warming

Global Warming Has Undone 6,500 Years Of Worldwide Cooling

Caused primarily by the burning of fossil fuels global warming circulates carbon dioxide (CO2), methane and other greenhouse gases into the atmosphere and is leading to the gradual heating of Earth’s surface, oceans and atmosphere.

A new study has surfaced suggesting that global warming has toppled six millennia of global cooling in the last 150 years.

The findings of the study show that global cooling started approximately 6,500 years ago when the long-term average global temperature peaked at around 0.7 degree Celsius warmer than the mid-nineteenth century. Since then, accelerating greenhouse gases have contributed to global average temperatures that are now moving past one degree Celsius above the mid-19th century.

Volcanos

Roundup of Global Volcanic Activity – New Activity for the Week 24 June 2020 – 30 June 2020

Asamayama | Honshu (Japan) : On 25 June JMA raised the Alert Level for Asamayama to 2 (on a scale of 1-5) noting that inflation on the W flank had been recorded since 20 June. The number of shallow (just below the summit, or 1-2 km a.s.l.) volcanic earthquakes had also increased; two volcanic tremors were detected on 20 June. Emissions form the summit crater had not changed and continued to be white in color and rise no more than 200 m above the crater rim.

Makushin | Fox Islands (USA) : AVO reported continuing numerous smaller earthquakes in an area about 10 km E of the Makushin’s summit at a depth of about 8 km during 24-30 June; the frequency and magnitude had been declining since 15 June but the rate became variable on 24 June. No surficial activity was visible in satellite or webcam images; only typical minor steaming from summit crater lake. Earthquakes with a M 3 and M 3.8 were recorded at 1653 and 1802 on 28 June, with the larger event strongly felt in Unalaska (14 km E). The Aviation Color Code and Volcano Alert Level remained at Yellow and Advisory, respectively.

Turrialba | Costa Rica : OVSICORI-UNA reported that occasional small ash emissions rose no higher than 100 m above the active crater at Turrialba each day during 23-29 June; no emissions were recorded on 27 June. A series of ash emissions were recorded at 1348, 1739, and 2303 on 28 June and at 0107, 0232, 0306, 0412, and 0818 on 28 June. At least two of those events (0107 and 0412) were accompanied by ballistics that were ejected onto the N wall of the active crater.
