Gulf Stream slowdown to moderate warming in Europe

New research confirms the likelihood of a Gulf Stream slowdown in the North Atlantic. Scientists suggest the phenomenon will spare Europe from the worst of global warming.

Thermohaline Circulation is a massive ocean current system that carries warm water from the tropics north toward Europe. As water evaporates in the North Atlantic its salinity and density increase, and it sinks, cools and is carried south again.

The global conveyor belt includes wind-driven warm water surface currents like the Gulf Stream and North Atlantic Drift — currents that moderate temperatures along the East Coast of the United States and Europe’s west coast.

Scientists have long predicted the Thermohaline Circulation would slow as global warming encouraged precipitation and polar melting, flooding the world’s oceans with cold freshwater.

Some researchers have speculated that a slowdown could precipitate an ice age in Europe.

New modeling by a team of researchers from the University of Sussex, Universidad Nacional Autónoma de México and the University of California, Berkeley, show that’s not the case.

The slowdown won’t reverse global warming and plunge Europe into another ice age. Instead, it is expected to slow the rate of warming in the region. While the rest of the world warms more quickly, Europe will warm at a moderated pace.

Wildlife

‘Ghost Fish’ Seen Live for First Time

A living, swimming “ghost fish” has been seen live for the first time ever.

The fish, part of the family Aphyonidae, was caught on camera during an ongoing National Oceanic and Atmospheric Administration (NOAA) exploration by the ship Okeanos Explorer. The exploration centres on the deep ocean at Mariana Trench Marine National Monument, a protected area spanning 95,216 square miles (246,608 square kilometres) east of the Philippines.

The secretive fish was swimming along a ridge 8,202 feet (2,500 meters) down, according to NOAA. The animal is about 4 inches (10 centimetres) long, with translucent, scale-less skin and eerie, colourless eyes. No fish in the family Aphyonidae has ever been seen alive before.

Volcanos

Roundup of Global Volcanic Activity

Kliuchevskoi (Kamchatka): The effusive-explosive eruption continues with no significant changes. The lava flow on the upper eastern flank remains well alimented while (strombolian) explosive activity has been low during the past days.

Shiveluch (Kamchatka): The volcano’s activity has been comparably low recently, but continues as viscous lava rises and accumulates at the active lava dome. A small collapse occurred yesterday evening, triggering a pyroclastic flow on the SW flank of the dome and producing an ash plume that rose to approx. 3.5 km above sea level. KVERT warns that “ash explosions up to 32,800 ft (10 km) a.s.l. could occur at any time. Ongoing activity could affect international and low-flying aircraft.”

Manam (Papua New Guinea): Darwin VAAC reported a small ash plume visible on satellite imagery extending 10 nautical miles west from the small island this morning. A moderate thermal anomaly from the volcano has been present, and become stronger during June-July, during the past months as well. This suggests that mild eruptive activity, perhaps the slow growth of a lava dome at the summit, with sporadic explosions continues.

Alaid (Northern Kuriles): The new eruptive phase at the remote volcano which had started around 4 July, after a possible pause in activity, continues with dominantly effusive activity. A recent satellite image allows to determine that fresh lava flows have erupted (or still are erupting) from the summit vent(s) and accumulate in the northern part of the summit caldera. Judging from the attached high-resolution satellite image, it seems likely that the main vent, a cinder cone that has been forming since the start of the recent eruption last October, remains active, likely with strombolian activity, while the lava flows themselves originate from two (?) flank vents at its northern feet.

Sinabung (Sumatra, Indonesia): Explosions of small to moderate size remain relatively frequent at the volcano. A stronger one occurred yesterday morning at 09:24 local time, generating an ash column that rose 3000 m above the summit.

Dukono (Halmahera): The volcano continues to erupt more or less continuous low levels ash plumes (7-10,000 ft altitude) that drift in various directions before dissipating.

Masaya (Nicaragua): The lava lake in the Santiago crater remains active, but has dropped a bit recently.

Turrialba (Costa Rica): Activity of the volcano has remained more or less unchanged during the past weeks. The western crater continues to produce intermittent (every few days) episodes of continuous, but relatively mild ash emissions. Not all of them can be observed due to cloud cover, but show up from the accompanying volcanic tremor. This activity is probably mainly phreatic in nature, as the volcano’s currently unstable shallow hydrothermal system interacts with an underlying small magma body. Recent ash samples were found to contain about 10% juvenile material which originates from the new magma. Whether the amount of magma participating in the surface activity increases (towards a more magma-driven eruption) or decreases (ceases) in the near to medium future, i.e. how the eruption evolves, will depend on ho the volume of magma involved and may other factors (gas content, internal pressure etc) and cannot be predicted at the moment.

Poas (Costa Rica): The volcano remains highly restless, the hydrothermal system probably being disturbed by a shallow magma body. A sudden and quite violent phreatic explosion, result of overheated ground water flashing to steam, occurred last Tuesday, ejecting mud and water to 200 m above the crater lake.

Sabancaya (Peru): A pilot reported seeing a small ash plume from the volcano today. On satellite imagery, no ash is visible, but it’s plausible that a small eruption occurred. The volcano has been producing sporadic emissions from time to time during the past months. Buenos Aires VAAC keeps Aviation Color Code at yellow.

Disease

Dengue Fever – Malaysia

Through July 12, Malaysian health officials have reported 60,085 dengue fever cases in 2016, after an additional 344 cases were reported yesterday. In addition, 134 dengue related fatalities have been reported by health authorities. Fifty-four percent, or 32,341 cases were reported from Selangor state, while 7,673 were reported from Johor and nearly 4500 from Kuala Lumpur.

Hepatitis A – Hawaii

Since the outbreak began, there have been 52 cases of hepatitis A reported to and now confirmed by DOH. All cases have been in adults on Oahu, 16 have required hospitalization. The department issued a Medical Advisory to all healthcare providers urging them to be vigilant and report all suspected hepatitis A infection immediately.

Typhoid in El Salvador

The El Salvador Ministry of Health issued a health warning about increased number of typhoid fever in the country reported in recent week, according to a local media report (computer translated). Health officials say the increases were detected via the early warning system. For the first six months of the year, El Salvador has seen 477 cases.

Cholera in Malawi

Health officials in Karonga are blaming fishermen for the continued cases of the deadly cholera disease in the lakeshore district.

Lewis Tukula, a district environmental health officer said there are continued cases of cholera in some areas in the district because fishermen are not cooperating on hygiene practices.

“So far 13 people have died and we have treated 235 people mostly in camps where fishermen stay. The camps have no toilets and they use lake water for drinking. We have been engaging them to dig toilets, not to drink lake water and embrace hygiene practices but they are not cooperating,” he said.

The disease is under full control in Mangochi, Zomba and Nkhata Bay among other districts hit by cholera during the rainy season.
