Storms and Floods

Tropical Storms – Roundup of Tropical Storms:

There are no current tropical storms.


The Amazon – Scientists and the media have documented deepening drought in the Amazon basin. But a new study finds that flood events are significantly intensifying too, becoming five times more common over the last century. The effect is caused by a combination of factors, including an increase in strength of the Walker circulation – an ocean-driven pattern of air circulation that carries warm moist air from the tropical Atlantic across South America towards the Pacific, resulting in Amazon precipitation. Human-driven climate change is a major contributing factor to this increased Amazon basin flooding. Intensifying flood events result in lives and property lost, and significant harm to croplands, pastures and livestock.

Global Warming

Greenland Is Melting Faster Than Ever

Greenland is melting faster today than it has at any time in the last 350 years, and probably much longer, new research finds.

Surface melt from the icy island has increased 50 percent in the last 20 years compared with the early 1800s, before the industrial era, researchers report (Dec. 5) in the journal Nature. The runoff alone is now contributing about a millimeter to the global average sea level per year.

Scientists tracking Greenland’s ice by satellite and on the ground have seen increasingly dire ice loss. Greenland loses ice both when icebergs calve off glaciers and when ice on the surface melts and flows to the sea as water. The meltwater flow is how the majority of the ice vanishes.

The amount of annual meltwater runoff from Greenland has increased from between 200 and 250 gigatons a year before humans started burning fossil fuels in large amounts to 350 gigatons a year today. It takes about 360 gigatons of meltwater to raise the global sea level by a millimeter.

Dengue Fever – Cambodia

Cambodian health officials are reporting an increase in the number of dengue fever cases in 2018. According to the National Centre for Parasitology, Entomology and Malaria Control (CNM), there have been 15,233 cases of dengue fever to date, which is about 50 percent higher compared to last year (11,000). In addition, 16 dengue related fatalities have been reported.


Roundup of Global Volcanic Activity – Ongoing Activity for the week of 28 November – 4 December 2018

Mayon | Luzon (Philippines) : PHIVOLCS reported that during 27 November-4 December white steam plumes rose from Mayon daily, and crater incandescence was visible almost nightly. At 0533 on 27 November a phreatic event generated a grayish-white ash plume that rose 300-500 m and drifted SW. A one-minute-long event that began at 0941 on 30 November produced another grayish-white ash plume. The Alert Level remained at 2 (on a 0-5 scale) and PHIVOLCS reminded residents to stay away from the 6-km-radius Permanent Danger Zone and the 7-km Extended Danger Zone on the SSW and ENE flanks.

Veniaminof | United States : AVO reported that the eruption of lava from the cone in Veniaminof’s ice-filled summit caldera continued during 27 November-3 December. Satellite and webcam data showed elevated surface temperatures. Steam and diffuse ash plumes were periodically identified in webcam and satellite images. During 27-28 November acoustic waves were recorded by regional infrasound sensors. Continuous low-amplitude tremor was recorded until the network went offline following a M 7 tectonic earthquake near Anchorage on 30 November. The Aviation colour Code remained at Orange (the second highest level on a four-colour scale) and the Volcano Alert Level remained at Watch (the second highest level on a four-level scale).
