Environment

Up to 1 Million Species Are at Risk of Extinction

Up to 1 million species are at risk of extinction due to human activity, according to a draft of a U.N. report set to be released on May 6. Preliminary conclusions from the report were obtained by the French news agency AFP.

Human activity, such as overconsumption, illegal poaching, deforestation and fossil fuel emissions, are pushing ecosystems toward a point of no return. A quarter of known plant and animal species are already threatened — and the loss of species is tens to hundreds of times higher than it has been, on average, over the last 10 million years.

Nature is buckling under the pressure, losing clean air, potable water, pristine forests, pollinating insects, fish populations, and storm-buffering mangroves.

What’s more, three-quarters of the land, almost half of marine environments and half of inland waterways have been “severely” changed by human activity, according to the report. These changes will harm humans, especially indigenous groups and those living in the poorest communities.

One-hundred and thirty nations will meet in Paris on April 29 to examine the 44-page report that summarizes a 1,800-page assessment of scientific literature conducted by the U.N.

Wildfires

Wildfires – Norway

Hundreds of people have had to leave their homes in Norway as emergency services try to extinguish forest fires raging in the south of the country. Some 148 homes were evacuated around the town of Sokndal, where fires have been burning since Tuesday.

Police say the fires are still out of control and warn that heavy winds could help them to spread. This month alone, wildfires have broken out in Sweden, Germany and the UK. April is very early for forest fires in Norway, and experts have warned of a dramatic increase across the continent.

Wildfires – Siberia

Wildfires tore through nearly 20 towns in the grasslands of southeastern Siberia between April 19-22. The fires injured at least 34 people, four of them critically, and left at least 645 people homeless in Zabaikalsky region. Some 11,800 livestock – including at least 1,277 cattle plus 489 horses – were destroyed, many of them roasted alive or killed after suffering terrible burns, according to various reports. Around 10,000 sheep are feared to have been lost. Some 120 pigs and 1,800 farm birds were burned in the wildfires.

In two cases, the wildfires truly came from China and Mongolia, The causes of two more fires were burning landfills. Two fires started because of breaks in power lines and the subsequent short circuits. In one settlement, residents threw smouldering ash from the furnace (igniting a fire).

Volcanos

Global Volcanic Activity – New Activity for the week of 17 April – 23 April 2019

Tengger Caldera | Eastern Java (Indonesia) : The Darwin VAAC reported that on 17 April ash plumes from Tengger Caldera’s Bromo cone rose to an altitude of 3 km (10,000 ft) a.s.l. and drifted W, based on webcam images and satellite data. On 21 April BNPB stated that ash emissions had been observed almost daily, and that tremor was recorded continuously. The Alert Level remained at 2 (on a scale of 1-4), and visitors were warned to stay outside of a 1-km radius of the crater.

Klyuchevskoy | Central Kamchatka (Russia) : KVERT reported that at 0921 and 1155 on 22 April ash plumes from Klyuchevskoy rose to altitudes of 5-5.5 km (16,400-18,000 ft) a.s.l. and drifted 130-140 km E, based on satellite and webcam data. KVERT noted that the ash content in the plumes had significantly increased compared to emissions first observed on 9 April. The Aviation colour Code was raised to Orange (the second highest level on a four-colour scale).

Asosan | Kyushu (Japan) : JMA reported that during 17-19 April white plumes from Asosan’s Nakadake Crater rose 1 km above the crater rim. A very small eruption was recorded at 0824 on 19 April, producing a plume that rose 500 m above the crater rim and drifted S. During an overflight that same day scientists observed a pool of hot water on part of the crater floor and a weak volcanic gas odor. According to the Tokyo VAAC a plume rose 500 m and drifted E at 1842. A weak volcanic gas odor was also evident. The Alert Level remained at 2 (on a scale of 1-5).
