Storms and Floods

Israel – Following a parched summer and fall, Israel was ravaged by wildfires a week ago, some of them deliberately set by terrorists. Now the Jewish state has a new weather-related challenge – a major winter storm that is bringing snow at high elevations, torrential rains at lower, coastal flooding and high winds. The storms — the first of the season — have brought sharp drops in temperature and winds of up to 56 mph, according to weather forecasts. Some 30 to 40 inches of rain fell Wednesday evening through Thursday, even more in northern regions — the result of low pressure over the Mediterranean Sea.

Global Warming

Climate change is ‘beyond point of no return’

Global warming is beyond the “point of no return”, according to the lead scientist behind a ground-breaking climate change study.

The report, by an exhaustive list of researchers and published in the Nature journal, assembled data from 49 field experiments over the last 20 years in North America, Europe and Asia.

It found that the majority of the Earth’s terrestrial store of carbon was in soil, and that as the atmosphere warms up, increasing amounts are emitted in what is a vicious cycle of “positive feedbacks”.

The study found that 55bn tonnes in carbon, not previously accounted for by scientists, will be emitted into the atmosphere by 2050.

“As the climate warms, those organisms become more active and the more active they become, the more the soil respires – exactly the same as human beings,” said Dr Crowther, who headed up the study at Yale Climate & Energy Institute, but is now a Marie Curie fellow at the Netherlands Institute of Ecology.

“Our study shows that this major feedback has already certainly started, and it will have a significant impact on the climate in the coming decades. This information will be critical as we strive to understand how the climate is going to change in the future. And it will also be critical if we are to generate meaningful strategies to fight against it.”

Dr Crowther, speaking to The Independent, branded Donald Trump’s sceptical stance on climate change as “catastrophic for humanity”.

Volcanos

Roundup of Global Volcanic Activity – Ongoing Activity for the week of 23 November-29 November 2016

Popocatepetl | Mexico : Each day during 22-28 November CENAPRED reported 129-324 steam and gas emissions from Popocatépetl that sometimes contained ash. Volcano-tectonic events were detected during 22-24 November, and explosions occurred on 22 and 24 November (4 and 7 events, respectively). At 0945 on 25 November an explosion generated a plume that rose 5 km above the crater rim and drifted SE and NE. Seismicity decreased after the event. Ashfall was reported in areas downwind including in the municipalities of Atlixco, Tochimilco, and San Pedro Benito Juárez. During 28-29 November there were 48 detected emissions. Beginning at 0559 emissions of water vapor, gas, and ash became constant, rising as high as 1.5 km above the crater rim and drifting NE. Incandescent fragments were ejected 300-800 m form the crater, mainly onto the NE flank. Ash fell in Atlixco, Chiautzingo, Domingo Arenas, Huejotzingo, Juan C. Bonilla, San Andrés Calpan, and San Martín Texmelucan (Puebla state), and in San Miguel (Tlaxcala state). The phase of continuous emissions and ejected material ended at 1630 on 30 November. The Alert Level remained at Yellow, Phase Two.

Sheveluch | Central Kamchatka (Russia) : KVERT reported that during 18-25 November lava-dome extrusion onto Sheveluch’s N flank was accompanied by strong fumarolic activity, dome incandescence, ash explosions with ash plumes as high as 6 km (19,700 ft) a.s.l., and hot avalanches. Satellite images showed a daily thermal anomaly over the dome. Satellite and video data recorded ash plumes rising to altitudes of 6-6.5 km (19,700-21,300 ft) a.s.l. and drifted 130 km SW, E, and NE on 18, 20, 22, and 24 November. The Aviation Color Code remained at Orange.

Suwanosejima | Ryukyu Islands (Japan) : Based on JMA notices and satellite-image analyses, the Tokyo VAAC reported explosions on 23, 25, and 29 November. Ash plumes on 25 and 29 November rose to altitudes of 1.8-2.1 km (6,000-7,000 ft) a.s.l. and drifted S and SW. On 29 November a pilot observed an ash plume that rose to an altitude of 3 km (10,000 ft) a.s.l.
