Space Weather – Sprites And Trolls At The Edge Of Space

We all know what comes out of the bottom of thunderclouds: lightning. But rarely do we see what comes out of the top. On August 10th, astronauts onboard the International Space Station were perfectly positioned to observe red sprites dancing atop a cluster of storms in Mexico. They snapped this incredible photo:

This shows just how high sprites can go. The photo shows their red forms reaching all the way from the thunderstorm below to a layer of green airglow some 100 km above Earth’s surface. This means sprites touch the edge of space, alongside auroras, meteors and noctilucent clouds. They are a true space weather phenomenon.

Global Warming

Central Asian glaciers shrinking fast

Central Asian glaciers have melted at four times the global average since the early 1960s, shedding 27 per cent of their mass, according to a study released today.

By 2050, warmer temperatures driven by climate change could wipe out half the remaining glacier ice in the Tien Shan mountain range, reported the study, published in Nature Geoscience.

At stake is a critical source of water for people in Kazakhstan, Kyrgyzstan and Uzbekistan, as well as a section of northwest China.

“Glaciers are actually huge water stores. They can balance water between wet and dry years,” said co-author Doris Duethmann, a researcher at the GFZ German Research Centre for Geosciences in Potsdam.

Tien Shan glaciers have lost an average of 5.4 billion tonnes of ice per year since the 1960s, totalling some 3,000 square kilometres (1,158 square miles).

The rate at which the glaciers shrank greatly accelerated in the 1970s and 1980s.

Climate models point to higher summer temperatures in coming decades along the 2,500 kilometres of the Tien Shan range, thus making the glaciers even more vulnerable, the study said.

Environment

Heat Wave in Israel

Forecasters say high humidity levels to intensify heat; Jordan Valley gears up for temperatures up to 48º. A punishing heat wave wracking Israel was set to peak on Sunday, with temperatures projected to rise above 40°C (104°F) in some areas.

In the southern resort city of Eilat, vacationers were expected to brave a sweltering 46ºC (115ºF), while cities and towns in the Jordan Valley will endure a combination of high humidity and blazing heat, with temperatures up to 48ºC (118ºF). In Tiberias, temperatures are expected to climb to 45°C (113ºF). But with 35 percent humidity in the afternoon hours, it will feel more like 58° (136ºF). Meanwhile, at the Dead Sea, the 44ºC weather (111º F) will feel more like 48°C (119ºF) when factoring in humidity. Tel Aviv’s relatively benign 35°C (95ºF) will feel more like 45°C (113ºF), given a whopping 60% humidity rate. Elsewhere in Israel, temperatures were predicted to climb to 42ºC (108º F) in Beersheba, 39ºC (102º F) on the Golan Heights and 35ºC (95º F) in Haifa.

Disease

Middle East Respiratory Syndrome coronavirus (MERS-CoV) – Saudi Arabia

Between 10 and 12 August 2015, the National IHR Focal Point for the Kingdom of Saudi Arabia notified WHO of 12 additional cases of Middle East respiratory syndrome coronavirus (MERS-CoV) infection, including 1 death.

Volcanos

Roundup of Global Volcanic Activity

Reventador (Ecuador): Activity at the volcano remains high, both internally (seismicity) and at the summit crater where viscous lava is being extruded. Occasional explosions and incandescent avalanches, possibly also a short lava flow result from this process.

Cotopaxi (Ecuador): No new explosions of significant size have occurred at the volcano during the past 48 hours. Seismic activity remains elevated and suggests that smaller ash emissions continue, however. Whether this is only a pause before another, possibly more violent phase of the eruption or already an end of this episode is too early to say. Ecuador’s ministry of civil protection maintains yellow alert for the communities of Francisco, Rumipamba, San Ramón, Mancheno, José Guango Bajo, and San Agustín del Callo (Mulaló).
