The Larsen C Iceberg Is on the Brink of Breaking Off

5 31 17 Brian LarsenCMay31 720 569 s c1 c c

The saga of the Larsen C crack is about reach its stunning conclusion. Scientists have watched a rift grow along one of Antarctica’s ice shelves for years. Now it’s in the final days of cutting off a piece of ice that will be one of the largest icebergs ever recorded.

It’s the latest dreary news from the icy underbelly of the planet, which has seen warm air and water reshape the landscape in profound ways.

The crack has spread 17 miles over the past six days, marking the biggest leap since January. It’s also turned toward where the ice shelf ends and is within eight miles of making a clean break. There’s not much standing in its way either.

“The rift has now fully breached the zone of soft ‘suture’ ice originating at the Cole Peninsula and there appears to be very little to prevent the iceberg from breaking away completely,” scientists monitoring the ice with Project MIDAS wrote on their blog.

Trump Pulls USA Out of Global Climate Change Pact

President Donald Trump is pulling the United States out of the Paris Agreement, a worldwide accord that was developed to curb rising global temperatures and limit climate change in the coming years.

“In order to fulfill my solemn duty to protect America and its citizens, the United States will withdraw from the Paris climate accord,” Trump said at a news conference on June 1.

The Paris Agreement is designed to slow global warming by reducing greenhouse gas emissions and by stepping up investments in “green” technology. Nearly 200 countries agreed on the deal in December 2015 and signed it in 2016. By working together, nations around the world are trying to keep the planet’s average temperature from rising more than 3.6 degrees Fahrenheit (2 degrees Celsius) above Earth’s average temperature during preindustrial times. However, the agreement has an even more ambitious goal: “to limit the temperature increase even further to 1.5 degrees Celsius [2 degrees F],” according to the United Nations.

The United States’ departure won’t cause the agreement to fall apart, but it will likely weaken it, especially if other countries follow suit. Moreover, countries that remain a part of the agreement might cooperate less with the United States in the future and, in a worst-case scenario, even impose carbon tariffs on the U.S., according to The New York Times.

Methane ‘blowout’

Giant craters on the Arctic sea floor were formed when methane gas previously trapped in ice was released with such force it blew through bedrock, Norwegian researchers say.

A study published in the latest edition of the journal Science says that during the last ice age, a sheet of ice up to two kilometres thick lay on the floor of the Barents Sea off Norway, holding vast amounts of methane in hydrate form — an ice-like mix of gas and water.

According to the researchers, when a warming climate caused the ice sheet to dissipate around 12,000 years ago, the methane concentrated in mounds and then was “abruptly released,” causing the craters.

Methane continues to seep out into the water to this day, Andreassen said, through more than 600 “gas flares” that remain near the craters.

Methane gas in northern waters is also an issue in Canada. This August 2009 photo shows methane gas bubbles in the Mackenzie River Delta in the Northwest Territories.

Wildlife

Medications, pesticides, found in blood of sea turtles on Great Barrier Reef

5713206 3x2 700x467

Heart and gout medications, pesticides, herbicides and other industrial chemicals have all been found in the blood of green sea turtles in the Great Barrier Reef, according to researchers.

The discovery was made as part of project led by the World Wildlife Fund (WWF), which compared samples from turtles in urban areas to the more remote locations.

Chemical exposure has been linked to stress and other side effects in wildlife, and the indications of inflammation and liver dysfunction were found in some green turtles.

The scientists said the worrying thing was there are more chemicals they could not identify than chemicals they could identify.

Faceless Fish

An Australian museum expedition has come across a species of fish not seen near the country since 1873. It has no visible eyes, gills or any other facial features except for two nostrils and a mouth at the bottom of its body.

Dubbed the “faceless cusk,” the fish measures roughly 22 inches in length and was captured by trawling a deep ocean trench off Australia’s eastern coast at a depth of around 2 miles.

According to Australia’s Commonwealth Scientific and Industrial Research Organization, the creature, known as a cusk eel, has been previously observed from the Arabian Sea, Indonesia, Papua New Guinea and Japan to Hawaii. But living at depths of up to 14,000 feet, it is rarely seen.

Roundup of Global Volcanic Activity – Ongoing Activity for the week of 24 May – 30 May 2017

Aira | Kyushu (Japan) : JMA reported 22 events at Showa Crater (at Aira Caldera’s Sakurajima volcano) during 22-29 May, seven of which were explosive. The explosions ejected material as high as 800 m above the crater rim, and as far away as 500 m. Ash plumes rose as high as 3.3 km on 23 May and 3.4 km on 29 May. Crater incandescence was detected on 25 May. A very small event occurred at Minamidake summit crater on 26 May. The Alert Level remained at 3 (on a 5-level scale).

Bezymianny | Central Kamchatka (Russia) : On 26 May KVERT reported that after an explosive eruption at Bezymianny on 9 March, and the effusion of several lava flows onto the dome flanks, the volcano became quiet. Gas-and-steam emissions continued, along with a thermal anomaly identified in satellite images. The Aviation colour Code was lowered to Yellow (the second lowest level on a four-colour scale).

Bogoslof | Fox Islands (USA) : An eruption at Bogoslof began at 1416 on 28 May prompting AVO to raise the Aviation colour Code (ACC) to Red and the Volcano Alert Level (VAL) to Warning. Pilot and satellite observations indicated than ash plumes rose at least 10.7 km (35,000 ft) a.s.l. and possibly as high as 13.7 km (45,000 ft) a.s.l. An observer on Unalaska Island reported seeing a large white-gray mushroom cloud form over Bogoslof, with ashfall to the W. The event lasted 50 minutes. On 29 May the ash cloud continued to drift NE. No detectable activity was observed in data from seismic or infrasound stations located on nearby Islands, and no new activity has been observed in satellite data. The ACC was lowered to Orange and the VAL was lowered to Watch.

Cleveland | Chuginadak Island (USA) : AVO reported that no significant volcanic activity at Cleveland was detected in seismic, infrasound, or mostly cloudy satellite images during 24-30 May. The webcam periodically recorded steam emissions. The Aviation colour Code remained at Orange and the Volcano Alert Level remained at Watch.

Colima | Mexico : On 26 May the Centro Universitario de Estudios e Investigaciones de Vulcanologia – Universidad de Colima reported that during the previous week seismic data revealed 36 high-frequency events, 20 long-period events, 2.6 hours of tremor, 12 landslides, and three low-intensity explosions. On 23 May sulfur dioxide emissions were below detectable limits (8.6 tons/day). A short-lived, low-amplitude episode of tremor was detected on 24 May.

Dukono | Halmahera (Indonesia) : Based on analyses of satellite imagery and wind model data the Darwin VAAC reported that during 24-30 May ash plumes from Dukono rose to an altitude of 2.1 km (7,000 ft) a.s.l. and drifted NW, W, and SW. Plumes drifted over 230 km W on 27 May.

Ebeko | Paramushir Island (Russia) : KVERT reported that during 23-24 May explosions at Ebeko were observed by residents of Severo-Kurilsk (Paramushir Island) about 7 km E. Ash plumes rose as high as 2 km (6,600 ft) a.s.l. The Aviation colour Code remained at Orange (the second highest level on a four-colour scale).

Kilauea | Hawaiian Islands (USA) : During 24-30 May HVO reported that the lava lake continued to rise, fall, and spatter in Kilauea’s Overlook crater. A portion of the N Overlook crater wall collapsed into the lake, causing lake agitation and depositing tephra at the Hawaiian Volcano Observatory and Jaggar Museum. Webcams recorded incandescence from long-active sources within Pu’u ‘O’o Crater, from a vent high on the NE flank of the cone, and from a small lava pond in a pit on the W side of the crater. The 61G lava flow, originating from a vent on Pu’u ‘O’o Crater’s E flank, continued to enter the ocean at Kamokuna adding to a growing delta. Narrow cracks on the delta parallel to the coast were noted. Surface lava flows were active above and on the upper slopes of the pali.

Langila | New Britain (Papua New Guinea) : Based on analyses of satellite imagery and wind model data, the Darwin VAAC reported that during 24-27 May ash plumes from Langila rose 2.1-3 km (7,000-10,000 ft) a.s.l. and drifted 75-85 km W and NW.

Manam | Papua New Guinea : RVO reported that Strombolian activity at Manam’s Southern Crater during 13-14 and 18 May generated lava flows that descended the SW valley. Lava flows traveled to 180-220 m elevation during 13-14 May but were significantly small on 18 May. Activity was low on other days during 13-26 May; ash plumes rose from the crater during 15-18 May. Conditions were quiet at Main Crater. RVO recommended that the Alert Level be lowered to Stage 1.

Nevado del Ruiz | Colombia : Servicio Geológico Colombiano’s (SGC) Observatorio Vulcanológico y Sismológico de Manizales reported that during 23-29 May seismicity at Nevado del Ruiz continued to indicate unrest. Five episodes of drumbeat seismicity (low-energy long-period events) were recorded between 1343 and 1930 on 29 May, likely signifying growing lava domes. Significant amounts of water vapor and gas continued to be emitted. Gas, steam, and ash plumes rose 880 m above the crater rim on 27 May and drifted NW and SW. A thermal anomaly was identified on 28 May. The Alert Level remained at III (Yellow; the second lowest level on a four-colour scale).

Pacaya | Guatemala : INSIVUMEH reported nighttime crater incandescence and small Strombolian explosions at Pacaya’s Mackenney cone during 27-28 May.

Sabancaya | Peru : Observatorio Vulcanológico del Sur del IGP (OVS-IGP) and Observatorio Vulcanológico del INGEMMET (OVI) reported that during 22-28 May explosive activity at Sabancaya slightly increased from the previous week, with an average of 41 explosions detected per day. Seismcity was dominated by long-period events, and the number and magnitude of hybrid events were low. Gas-and-ash plumes rose as high as 2.8 km above the crater rim and drifted more than 30 km E and SE. The MIROVA system detected two thermal anomalies.

Santa Maria | Guatemala : INSIVUMEH reported that during 24-25 May avalanches of material from Santa María’s Santiaguito lava-dome complex traveled short distances down the flanks. During 27-30 May weak explosions generated ash plumes that rose 600-700 m and drifted W and SW. Ashfall was reported in Monte Claro (S).

Sinabung | Indonesia : Based on PVMBG observations, webcam and satellite images, and wind data, the Darwin VAAC reported that during 24-29 May ash plumes from Sinabung rose 3.7-5.8 km (12,000-19,000 ft) a.s.l. and drifted in multiple directions.

Turrialba | Costa Rica : OVSICORI-UNA reported that tremor amplitude at Turrialba fluctuated from low to high levels during 23-30 May, often corresponding to emission characteristics. Periods of volcano-tectonic and long-period events were also recorded. During 24-26 May several passive and sporadic ash emissions rose no higher than 500 m above the vent and drifted NW and SW. Frequent and small explosions during 26-27 May generated ash plumes that rose higher than 500 m above the vent, and ejected material higher than 200 m and no farther than 100 m towards Central Crater. Small explosions during 27-29 May produced ash plumes that rose 300-500 m.
