Wildfires

Wildfires – Israel

Negligence is suspected of being a factor in a number of wildfires on Tuesday, including a forest fire that scorched hundreds of hectares outside Shlomi in the western Galilee.

Police and firefighters deployed helicopters and other aircraft to fight the blaze, which also damaged a power line, causing electrical failures in the area.

On the other side of the Galilee, a forest fire broke out in two spots next to the Jordan River near a popular rafting spot. The cause of this fire was not announced, and all visitors had to be evacuated from the area.

In Jerusalem, two forest fires broke out on Tuesday, where temperatures hit a high of 33 degrees. One broke out near the Mount of Olives, but firefighters managed to contain it before it could cause any damage or injuries. Another blaze began in the city’s Peace Forest near the Abu Tor neighbourhood. It, too, was contained, but residents of a nearby street had to be evacuated due to high levels of smoke.

Global Warming

Carbon dioxide making earth greener, reveals new research

The earth is getting greener because of higher carbon dioxide (CO2) levels in the atmosphere, new research shows.

Observations by Nasa satellites over the past 33 years show that there has been a steady increase in leaves on plants and trees, which scientists think is because of the higher CO2 levels. Leaves absorb CO2 and combine it with water to produce food for the plants. The study was done by an international team of 32 scientists from 24 institutions in eight countries and has been published in the journal Nature Climate Change.

Burning oil, gas, coal and wood for energy releases CO2 in to the air. The amount of CO2 in the air has been increasing since the industrial age and currently stands at a level not seen in at least half-a-million years. It is the chief culprit of climate change.

About 85% of the Earth’s ice-free lands is covered by vegetation. The area of all green leaves on Earth is equal to, on average, 32% of the Earth’s total surface area – oceans, lands and permanent ice sheets combined. “The greening over the past 33 years reported in this study is equivalent to adding a green continent about two-times the size of mainland USA (18 million km2), and has the ability to fundamentally change the cycling of water and carbon in the climate system.

Every year, about one-half of the 10 billion tons of carbon emitted in to the atmosphere from human activities remains temporarily stored, in about equal parts, in the oceans and plants.

Does this mean that high emissions are beneficial for the earth and humanity? Although many contrarians have argued this, the study authors warn that this is not so.

The fallacy of the contrarian argument is two-fold. First, the many negative aspects of climate change, namely global warming, rising sea levels, melting glaciers and sea ice, more severe tropical storms, etc. are not acknowledged. Second, studies have shown that plants acclimatize, or adjust, to rising CO2 concentration and the fertilization effect diminishes over time.

CO2 fertilization is only one, albeit a predominant, reason why the Earth is greening. The study also identified climate change, nitrogen fertilization and land management as other important reasons.

Chernobyl Anniversary

Ukrainians held candlelit vigils to mark 30 years since the world’s worst nuclear accident – as Chernobyl spewed radiation across Europe and left several thousand people dead or dying.

At least 30 people were killed on site and several thousand more are feared to have died from the radiation fallout in one of the world’s worst man-made disasters, which forced a global rethink about the wisdom of relying on atomic fuel.

The exact number of dead remains a subject of intense debate because the Soviet authorities kept most of the information about Chernobyl under wraps.

Wildfires

Wildfires – Nepal

Wildfires have been raging on in more than 50 community forests and national forests in Kanchanpur for more than a week, putting more than 10,000 hectares of forestland in peril, Kanchanpur district forest office informed. Shuklafanta wildlife reserve is among the forests that are at risk, the office said, adding that 10,200 hectares of forestland has caught fire.

9 homes were gutted in the Panchthar district by the wildfires.

Wildfires – Scotland

Dozens of firefighters were battling two large wildfires in separate parts of the Highlands last night. Although no evacuations have been ordered, the fires came within a quarter mile of Stroupster wind farm and the nearest residential property.

Middle East respiratory syndrome coronavirus (MERS-CoV) – Bahrain

On 10 April 2016, the National IHR Focal Point of Bahrain notified WHO of a fatal case of Middle East respiratory syndrome coronavirus (MERS-CoV). This is the first case reported in Bahrain.

Newcastle Disease – Israel

Nine more outbreaks of Newcastle disease have been found in Israel. The outbreaks occurred in the Hazafon, Haifa and Hamerkaz provinces.

Over 70,000 birds died and 260,000 were destroyed in the nine outbreaks, which occurred in broilers, breeders and backyard chickens. Some of the outbreaks were not detected by clinical signs, but rather by active surveillance measures put in place to combat the disease.

The source of the outbreak was unknown, and the authorities are fighting the outbreak by disinfection, stamping out, movement controls, zoning and quarantine measures.

India – Rain, hail and windstorms continue to hit the North East region of the Indian subcontinent, causing landslides and floods affecting thousands of people in the region. Also, heavy rainfall has damaged many houses and caused flooding in low-lying villages in Manipur, officials said on Sunday. Incessant rainfall has also led to mud slips, damage to retaining walls, power infrastructures, houses, road blockage, drainage blockage etc.

China – China Meteorological Administration (CMA) and the Ministry of Water Resources on Sunday evening jointly issued a warning for mountain floods from Sunday night to Monday night. The floods are expected to hit the southeastern part of Tibet, the eastern part of Guangdong and, in particular, the western part of Yunnan.

Volcanos

Roundup of Global Volcanic Activity

Kliuchevskoi (Kamchatka): The activity of the volcano has intensified, in particular during the past 24-36 hours. KVERT reported that strong strombolian explosions produced an ash plume that rose to 8-9 km altitude that drifted more than 400 km to the SW. Webcam images have been mostly unclear, but view from this evening (dawn in Kamchatka) suggest that a new lava flow might have started to descend the volcano’s flanks, which would be a typical occurrence if the magma supply rate has indeed increased. An intense thermal anomaly is being recorded on satellite data as well. KVERT alerted this morning that the “explosive eruption of the volcano continues. Ash explosions up to 19,700-26,240 ft (6-8 km) a.s.l. could occur at any time. Ongoing activity could affect international and low-flying aircraft.” The aviation color code was raised to ORANGE.

Sinabung (Sumatra, Indonesia): The volcano’s current and long-lasting eruption (now well in its 3rd year) continues essentially unchanged: viscous lava slowly rises into the summit crater, building up a complex dome that over-spills as sticky lobes onto sections of the upper outer slopes on the southeastern side. When these steeply emplaced lava lobes become too large, they also become unstable and begin to collapse. These collapses generate glowing rockfalls and small to moderate pyroclastic flows when enough material rich in gas is involved. From time to time, accumulated gas trapped beneath the dome also gives way to vertical explosions. These explosions have been occurring almost daily over the recent months, producing ash plume that rise 1-2 km, typically.

San Cristobal (Nicaragua): The volcano had a series of new explosive eruptions on Friday, producing ash plumes that rose up to approx. 2 km above the summit crater, drifted south and caused moderate ash fall in areas up to 10-15 km south and southeast of the volcano, including Las Brisas, Santa Narcisa, and Chichigalpa town. The new series of eruptions began on 22 April around 10:20 local time with a first explosion, followed immediately by a stronger one (image). Weaker explosions followed intermittently throughout the day, but activity seems to have faded again as of today.

Nevado del Ruiz (Colombia): The volcano produced a small ash plume today, Manizales volcano observatory reported to Washington VAAC. Webcam views are obscured by weather clouds. Sporadic mild ash emissions have been occurring from the volcano from time to time during the past weeks.
