Global Warming

Rainforest trees may have been dying faster since the 1980s because of climate change

Tropical trees in Australia’s rainforests have been dying at double the previous rate since the 1980s, seemingly because of climate impacts, according to the findings of a long-term international study. This research has found the death rates of tropical trees have doubled in the last 35 years, as global warming increases the drying power of the atmosphere.

Deterioration of such forests reduces biomass and carbon storage, making it increasingly difficult to keep global peak temperatures well below the target 2 °C, as required by the Paris Agreement.

Monkeypox – England

In a follow-up on the monkeypox situation in England, the UK Health Security Agency (UKHSA) has detected 2 additional cases of monkeypox, one in London and one in the South East of England. The latest cases bring the total number of monkeypox cases confirmed in England since May 6 to 9.

Volcanos

Roundup of Global Volcanic Activity – New Activity for the week 11 May – 17 May 2022

Awu – Sangihe Islands : PVMBG had raised the Alert Level for Awu to 2 (on a scale of 1-4) on 12 December 2021 because of a notable increase in the number of both shallow and deep volcanic earthquakes. Since then the number of shallow and deep volcanic earthquakes averaged 8 and 5 events per day, respectively. Gas emissions had not been visible, though weather conditions sometimes prevented views of the volcano. Another significant seismic increase was recorded on 9 May, with 88 shallow events and 147 deep events, and then again the following day with 90 shallow events and 203 deep events. At 1500 on 11 May a white emission was observed rising about 30 m above the crater rim.

Cleveland – Chuginadak Island (USA) : AVO reported that during 11-17 May elevated surface temperatures over Cleveland were identified in satellite images. No significant seismic or infrasound activity was detected. A continuous sulfur dioxide plume drifted 500 km during 15-16 May.

Krakatau – Sunda Strait : The Darwin VAAC reported that during 10-12 May ash plumes from Anak Krakatau rose to 2.4 km (8,000 ft) a.s.l. and drifted E, N, NW, and W based on satellite images and weather models. On 13 May satellite images showed a narrow ash plume drifting SE and E at an altitude of 2.4 km. Dense steam plume with minor ash content rose to 2.4 km and drifted NE, N, NW, and W during 14-16 May.

Reykjanes – Reykjanes Peninsula : The National Commissioner of the Icelandic Police declared a level of “uncertainty” for the Reykjanes Peninsula on 15 May, noting that the declaration meant that responders and agencies were to review their preparedness plans in response to recent increases in seismicity and deformation. More than 3,000 earthquakes had been detected near Eldvörp in the Reykjanes/Svartsengi volcanic system during the past week. Nine earthquakes above M 3 and two earthquakes above M 4 were recorded during 15-16 May; the largest event was a M 4.3 which was recorded at 1738 on 15 May. The earthquakes were located at depths of 4-6 km. GPS and InSAR data detected inflation W of Thorbjörn during the previous two weeks, likely caused by a magmatic intrusion at 4-5 km depth.
