India – Update – Heavy rains, inundation, and floods continue to wreak havoc in India, with the death toll rising in Assam, Bihar and West Bengal this week. Over a crore people have been affected by the situation, with many shifted to relief camps and temporary shelters. Train and rail services of the Eastern Railway have also taken a hit, with many lines inundated or damaged in the rains. The number of lives claimed by the floods in Assam has touched 123; 11 more deaths were reported on Wednesday. Nearly 33.45 lakh people in 24 districts of the state have been affected till now. The death toll in Bihar has risen to 72, with over 73 lakh people affected by incessant rains and inundation. Fears of floods have gripped the state, after at least 14 districts in the north were submerged, the latest being Gopalganj. The toll in West Bengal hit 32 on Wednesday. Over 14 lakh people have been affected in six northern districts of the state, namely Malda, Alipurduar, Jalpaiguri, Cooch Behar and South and North Dinajpur. Around 1.2 lakh people have been displaced in the West Garo Hills district of Meghalaya due to floods caused by the rising of the Brahmaputra tributary, the Jingiram River. Meanwhile, the capital of Karnataka received the highest rainfall in a day in August in 127 years on Tuesday. Heavy rains lashed the city, which received 12.8 cm of rain in five hours from Monday night to Tuesday morning, while no deaths were reported, power lines were snapped, vehicles submerged, streets were flooded and trees were uprooted.


Global Temperature Extremes

The week’s hottest temperature was 121.0 degrees Fahrenheit (49.4 degrees Celsius) in Al Qaysumah, Saudi Arabia.

The week’s coldest temperature was minus 103.0 degrees Fahrenheit (minus 75.0 degrees Celsius) at Vostok, Antarctica.

Temperatures were tabulated from the more than 10,000 worldwide synoptic weather stations. The United Nations World Meteorological Organization sets the standards for weather observations, and provides a global telecommunications circuit for data distribution.


Wildfires – Balkans, Europe

Firefighters in Montenegro and Croatia are trying to extinguish several wildfires on and near the Adriatic coastline that have already destroyed swathes of forest and threatened villages.

A fire on Mount Lovcen national park in central Montenegro is endangering a mountain top mausoleum in which the well-known 19th century Montenegrin poet and ruler Petar Petrovic Njegos was buried. Officials say the fires are worsened by strong winds.

In neighboring Croatia, a huge fire that has threatened villages near the Adriatic resort of Sibenik has been put under control with the help of 150 firefighters, army troops and firefighting planes.


Middle East respiratory syndrome coronavirus (MERS-CoV) – Saudi Arabia

Between 4 July and 12 August 2017, the national IHR Focal Point of Saudi Arabia reported 26 additional cases of Middle East respiratory syndrome coronavirus (MERS-CoV) infection including six deaths, and two deaths among previously reported cases.


Roundup of Global Volcanic Activity – New Activity for the week of 9 August – 15 August 2017

Kerinci | Indonesia : Based on satellite data, the Darwin VAAC reported that on 13 August an ash plume from Kerinci rose to an altitude of 4.3 km (14,000 ft) a.s.l. and drifted WSW. Plumes drifted almost 30 km on 17 November.

Pacaya | Guatemala : On 12 August INSIVUMEH reported that Strombolian explosions at Pacaya’s Mackenney cone were observed. During 12-13 August the number of Strombolian explosions increased to a rate of 5-7 per hour, and ejected incandescent material was mainly visible at night. Explosions vibrated structures in communities within a 5-km radius. Activity continued at a similar level on 15 August.

Piton de la Fournaise | Reunion Island (France) : OVPF reported that the eruption at Piton de la Fournaise that began on 14 July continued through 15 August. Weather clouds often prevented visual confirmation of activity, though observers periodically noted that small amounts of material were ejected from a small vent on the N flank of the eruptive vent. Some active pahoehoe flows were visible at a distance of 2 km from the cone, though most of the flow activity was confined to lava tubes.

Sangay | Ecuador : Based on information from the Guayaquil MWO, the Washington VAAC reported that on 12 August an emission from Sangay rose to altitudes of 6.1-6.4 km (20,000-21,000 ft) a.s.l. and drifted SW and NW. Ash in the emission was not detected in satellite data. On 13 August satellite data showed a well-defined thermal anomaly over the volcano, and an ash plume drifting 55 km SW.

Sangeang Api | Indonesia : Based on analyses of satellite imagery, the Darwin VAAC reported that on 12 August an ash plume from Sangeang Api rose to 2.7 km (9,000 ft) a.s.l. and drifted NW.

Ulawun | New Britain (Papua New Guinea) : Based on analyses of satellite imagery and wind model data, the Darwin VAAC reported that during 9-10 August ash plumes from Ulawun rose to 2.4 km (8,000 ft) a.s.l. and drifted NW and W.

The Escalating Global-Warming Crisis, in One Chart

Last month tied July of 2016 for the hottest month on record, according to a new analysis from researchers at NASA’s Goddard Institute for Space Studies. Sixteen of the 17 hottest years on record have occurred in the 21st century, including 2015 and 2016, both of which saw a temperature boost thanks to a strong El Niño event. (El Niños bump up surface temperatures by churning warm water to the ocean surface.) Record-setting temperatures in 2017 are especially concerning now that there is no El Niño; in other words, most of the excess heat this year is due to human-induced climate change.

Wildfires – British Columbia, Canada

B.C. wildfires have destroyed a record amount of forest, brush and grassland, surpassing the devastation of nearly 60 years ago. About 8,944 square kilometres have been scorched by fires, breaking the 1958 record of 8,550 square kilometres.

With no rain in the forecast for the wildfire-ravaged southern parts of the province, it seems inevitable that more land will be burned.

A total of 1,029 fires have occurred since the April 1 start of the wildfire season, and 149 of them are still burning.

A fire that destroyed dozens of homes near Ashcroft six weeks ago has now consumed even more structures in the Green Lake area almost 100 kilometres away. Crews have not been able to access the site to determine exactly what has been lost as the active blaze that is more than 1,600 square kilometres in size continues to pose a danger.


Texas, USA – Anthrax

The first Anthrax cases of 2017 have been confirmed in five cattle on a Crockett County premises, according to the Texas Animal Health Commission (TAHC) this week. The premises in Crockett County is located approximately 13 miles east of Ozona and has been quarantined.

Samoa – Dengue Fever

The Samoan Ministry of Health issued a dengue fever alert after two dozen cases were reported, including two suspected dengue-related deaths.

India, Nepal, Bangladesh – Nearly 250 people have died in the last few days as a result of flooding and landslides that have devastated parts of northern India, Nepal and Bangladesh.

Millions of people have been displaced across the region, and 245 people are recorded to have been killed by collapsed buildings or by drowning.

In Nepal, incessant rain has flooded hundreds of villages leaving 110 people dead. The government has come under fire for not responding fast enough to the disaster.

As security forces scrambled to rescue those marooned on rooftops and helicopters distributed food and water to the worst-hit districts yesterday, the home ministry spokesman Ram Krishna Subedi said relief supplies were being mobilised as soon as possible. Elephants were deployed to help rescue those stranded following three days of torrential rain, including 700 tourists in the popular town of Chitwan.

Across Nepal’s southern border, 13 districts have been hit by severe flooding in the Indian state of Bihar, leaving 41 people dead. Boats and helicopters were used to distribute food packets, medicine and drinking water to those affected and some 200,000 people have been provided with temporary shelter across 250 relief camps set up by the authorities in schools and government buildings.

In the northern state of Himachal Pradesh, emergency workers have been scouring the area hit by a massive landslide that swept two buses into a deep gorge on Sunday, killing 46 people.

A further 21 people died in the remote north-eastern state of Assam, where soldiers were deployed to rescue those stranded on rooftops.

Meanwhile a third of Bangladesh is flooded after monsoon rains swept through the densely populated riverine country.

At least 27 people have died and a further 600,000 have been marooned across the low-lying delta region, according to Bangladesh’s disaster management minister, Mofazzal Hossain Chowdhury.

Fast-melting Arctic – Cause and Effects

International researchers embarked on a month-long, 10,000 kilometer (6,200-mile) journey to document the impact of climate change on the forbidding ice and frigid waters of the Far North

Glaciers, sea ice and a massive ice sheet in the Arctic are thawing from toasty air above and warm water below. The northern polar region is heating up twice as fast as the rest of the planet and that’s setting off alarm bells.

“The melting of the Arctic will come to haunt us all,” said German climate scientist Stefan Rahmstorf.

While global leaders set a goal of preventing 2 degrees Celsius (3.6 degrees Fahrenheit) of man-made warming since pre-industrial times, the Arctic has already hit that dangerous mark. Last year, the Arctic Circle was about 3.6 degrees (6.5 degrees Fahrenheit) warmer than normal.


The Arctic is mostly ocean covered with a layer of ice; changes from ice to water often kick in a cycle that contributes to global warming.

Sea ice is white and it reflects the sun’s heat back into space. But when it melts, it’s replaced with dark ocean that strongly absorbs it, said former NASA chief scientist Waleed Abdalati, who heads the environmental research program at the University of Colorado.

That heat gets transferred back up to the atmosphere in the fall and winter. As that happens, water vapor — a greenhouse gas — hangs around, trapping more heat. More clouds form around that time, also acting as a blanket, said Mark Serreze, director of the National Snow and Ice Data Center in Boulder, Colorado.


Winter is crucial. Three times in the past two cold seasons, air temperatures near the North Pole were near or even a shade above freezing. That’s about 50 degrees warmer than it should be. From last November through February, Barrow, Alaska — the northernmost U.S. city — was 7 degrees Celsius (13 degrees Fahrenheit) warmer than the 20th century average, and much of the Atlantic Arctic off Norway and Greenland was as hot.

Warm winters weaken sea ice, which floats on the ocean surface. It’s supposed to recover, spread more across the Arctic and get thicker in the winter so it can withstand the warmth of the summer. But a warmer winter means less protection when the heat hits.

In September 2016, the time of year the spread of ice across the Arctic is at its lowest, Arctic sea ice was the second lowest day on record, about 40 percent below the lowest day measured in 1979 when satellite records started. Between those two days 37 years apart, the Arctic lost enough sea ice to cover Alaska, Texas and California combined.

Then it didn’t grow back that much this winter, setting record low amounts from November through March, when sea ice reaches its peak spread.


Of all the global warming warning signs in the Arctic, “it is the sea ice that is screaming the loudest,” Serreze said.

That’s a problem because a growing body of studies connects dwindling sea ice to wild weather. The reduced winter sea ice interacts with warmer oceans to change conditions in the air that then triggers a potent noticeable shift in the jet stream, the giant atmospheric river that controls much of our weather, said Rutgers University climate scientist Jennifer Francis. This theory is still debated by scientists, but increasingly more researchers are agreeing with Francis.

It’s not just sea ice on the decline. Glaciers in the Arctic are shrinking. And the massive Greenland ice sheet is slowly but steadily melting and that can add a big dose to sea level rise. Since 2002, it has lost 4,400 billion tons (4,000 billion metric tons) of ice.

Then there’s the Arctic carbon bomb. Carbon dioxide and methane — which traps even more heat — are stuck in the permafrost in places like Alaska and Siberia.


No Arctic creatures have become more associated with climate change than polar bears. The U.S. Fish and Wildlife Service estimated in January that about 26,000 specimens remain in the wild. Population counts of polar bears are notoriously difficult, and researchers are unsure how much their numbers have changed in recent years. But the Fish and Wildlife Service warned that melting sea ice is robbing the bear of its natural hunting ground for seals and other prey.

While some polar bears are expected to follow the retreating ice northward, others will head south, where they will come into greater contact with humans — encounters that are unlikely to end well for the bears.

The walrus, for example, may spend more time on the mainland. They’re very prone to disturbance so that’s not a good place for walrus to be.

Alarms bells are ringing about the future of the red king crab — a big earner for Alaska’s fishing industry — because rising levels of carbon dioxide, a driver of global warming, are making oceans more acidic. Scientists found that juvenile crabs exposed to levels of acidification predicted for the future grew more slowly and were more likely to die.

Algae that cling to the underside of sea ice are also losing their habitat. If they vanish, the impact will be felt all the way up the food chain. Copepods, a type of zooplankton that eats algae, will lose their source of food. The tiny crustaceans in turn are prey for fish, whales and birds.

Meanwhile, new rivals from the south are already arriving in the Arctic as waters warm. Orca have been observed traveling further north in search of food in recent years, and some wildlife experts predict they will become the main seal predator in the coming decades, replacing polar bears.

Humans are also increasingly venturing into the Arctic in search of untapped deposits of minerals and fossil fuels — posing a threat to animals. The potential for oil spills from platforms and tankers operating in remote locations has been a major cause for concern among environmentalists since the 1989 Exxon Valdez disaster off Alaska killed a quarter of a million seabirds, as well as hundreds of seals and sea otters.
