Antarctic ‘Doomsday Glacier’ Is ‘Holding On By A Fingernail’
A new study found that the Thwaites Glacier in Antarctica, also known as the Doomsday Glacier, is disintegrating faster than previously believed due to climate change, and its collapse could cause a catastrophic rise in sea levels globally.
Ice loss from West Antarctica’s second largest marine ice stream, Thwaites Glacier, is currently a major uncertainty for future sea-level projections. Its bed deepens upstream to >2 km below sea level, and warm, dense, deep water delivers heat to the present-day ice-shelf cavity, melting its ice shelves from below, seriously affecting its stability.
Eastern Mediterranean, Middle East warming almost twice as fast as global average
The eastern Mediterranean and Middle East are warming almost twice as fast as the global average, with temperatures projected to rise up to 5 degrees Celsius (9 degrees Fahrenheit) by the end of the century if no action is taken to reverse the trend, a new report says.
The region will experience “unprecedented” heat waves, more severe and longer-lasting droughts and dust storms and rainfall shortages that will “compromise water and food security” for the region’s 400 million people. The eastern Mediterranean and the Middle East are more susceptible to warming trends because of their unique natural characteristics, like large desert expanses and lower water levels, the study said.
Wildfires – California
Wednesday afternoon the Mosquito Fire east of Foresthill, California spread significantly north and east. Aircraft have mapped it at 4,223 acres, an increase of approximately 3,000 acres yesterday.
Russia Now Must Fight Forest Fires Almost Year Around – Due to Global Warming
Because of global warming and the impact of current land use policies, Russia must now fight forest fires almost year around. When the fire fighting season was shorter, Russian officials at all levels were able to use the quiet times to recover; but now, they must fight fires every month and that is having a negative impact on their ability to do so. And it is not just that enormous areas are burning throughout the year but that these fires are both caused by and leading to a further drying up of rivers on which Russia depends for transportation in many places but also are having a negative impact on public health, given the smoke from them, and on the economy, because they are blocking roads.
Polio – Pakistan
Two more children have been paralyzed by the wild poliovirus in southern Khyber-Pakhtunkhwa. These cases are the 16th and 17th case respectively from Pakistan at large this year.
Bird Flu – Dolphins
bottlenose dolphin found dead in Florida’s Dixie County was infected with the highly pathogenic avian influenza virus, or HPAIV, making it the first cetacean to be found with the virus in America and only the second known case in the world.
Roundup of Global Volcanic Activity – New Activity for the week 31 August – 6 September 2022
Chikurachki – Paramushir Island (Russia) : KVERT reported that an ash plume from Chikurachki was identified in satellite images drifting 94 km ESE on 26 August. According to the Tokyo VAAC an ash plume was identified in satellite images at 1730 on 2 September, local time, drifting NE at an altitude of 3.7 m (12,000 ft).
Karthala – Grand Comore Island : A significant increase in the number of small earthquakes beneath Karthala’s W flank began to be detected on 15 July. The abnormal activity persisted.
Marapi – Central Sumatra : In a special notice posted on 2 September PVMBG reported that tiltmeter deformation data for Marapi showed a trend of inflation at the summit and deflation along the flanks. Seismicity continued to fluctuate with the dominating signal indicating hydrothermal activity. A phreatic eruption was the most likely kind of volcanic activity that could occur at the volcano, based on the recent data, and it could occur without warning.
Semisopochnoi – Aleutian Islands (USA) : AVO reported ongoing low-level seismicity and steam emissions at Semisopochnoi during 30 August-6 September. Weakly elevated surface temperatures were identified in satellite images during 1-2 September. Several small ash eruptions from the N crater of Mount Cerberus were visible in webcam images during 2-3 September and detected in seismic and infrasound data. Satellite and webcam views were cloudy during 4-5 September.
Ta’u – American Samoa (SW Pacific) : HVO reported that an earthquake swarm around Ta’u, in the Manu’a Islands of American Samoa, continued during 30 August-6 September. Less than 30 earthquakes per day were large enough to be felt by residents and many more earthquakes undetectable by humans were also recorded; no earthquakes were reportedly felt during 5-6 September. The data suggested that the earthquakes were consistently occurring in an area about 5-15 km off the N shore of the island, at depths of 10-15 km below the surface. There was no change in the frequency or size of earthquakes and the position of the swarm remained unchanged. USGS staff installed GPS equipment during 4-6 September.
