Japanese proposal to allow the resumption of commercial Whaling defeated at the International Whaling Commission's biannual meeting in Florianopolis, Brazil.

A proposal by Japan that Whale stocks had recovered to the extent that commercial Whaling could be resumed was rejected at the  International Whaling Commission's biannual meeting in Florianopolis, Brazil, on 14 September 2018. Japanese negotiators had argued that the recovery of many populations of Whales means that they would be able to withstand some commercial hunting, that the international moratorium on the activity is intolerant of other views, and that the inability to harvest Whales commercially threatened Japan's long-term food security. However, the proposals were rejected by 41 votes to 27, with two abstentions, with opponents to the measure claiming that policing of legal Whaling had in the past proved almost impossible, with species after species being hunted to the brink of extinction, and that there is little need (or demand) for Whale meat as a food in the twenty first century.

Japan is still allowed to harvest 333 Minke Whales, Balaenoptera spp., each year, officially for scientific research, but critics of the policy claim that as the meat of these animals is sold, the policy is effectively a cover for commercial Whaling. The nation had been allowed to take up to 1000 Minke per year until 2012, when the International Court of Justice ruled that such a large harvest could not be justified as scientific research. Minke are also hunted legally by Norway, and Iceland where Minke Whales are hunted for domestic consumption and Fin Whales, Balaenoptera physalus, for meat which is exported to Japan. In South Korea Minke Whales caught as by-catch can be sold, with critics claiming that this policy also covers for commercial Whaling.

Whaling is also permitted using indigenous methods by some countries, including the Faroe Islands, where Long-finned Pilot Whales, Globicephala melas, and Atlantic White-sided Dolphins, Lagenorhynchus acutus, are targeted, with about 800 animals being killed each year, by driving them onto beaches and spearing them, Greenaland, where a variety of Whale species are targeted, Alaska, where indigenous groups hunt about 500 Beluga Whales, Delphinapterus leucas, and about 40 Bowhead Whales, Balaena mysticetus, each year, the Russian Far East, where indigenous groups take about 140 Grey Whales, Eschrichtius robustus, Canada, where several indigenous groups take a small number of Whales in the Arctic Circle each year, the Caribbean, where several groups in Grenada, Dominica, St Lucia and the Grenadines are allowed to take small numbers of Short-finned Pilot Whales, Eschrichtius robustus, Pygmy Killer Whales, Feresa attenuata, Spinner Dolphins, Stenella longirostris, and Humpback Whales, Megaptera novaeangliae, and the Indonesian islands of Lembatta and Solor, where Sperm Whales, Physeter macrocephalus, and Dolphins are hunted. None of these groups sell Whale meat commercially, though some is traded or bartered within communities (Greenland has been repeatedly accused of breaching this rule by selling Whale meat to tourists, and exporting Whale meat to Denmark).

Other than this, all Whaling activities worldwide have been banned since 1985, when a moratorium on the taking of Whales agreed by the International Whaling Commission in 1982 came into place. However, in many cases this is not because Whales are considered to be endangered, but because of the difficulties involved in policing the industry, and considerations about the intelligence and emotional well being of Whales, which Japan and some other nations argue is outside the original remit of the commission. Of the two species of Minke Whale the Common Minke Whale, Balaenoptera acutorostrata, is considered to be of Least Concern under the terms of the International Union for the Conservation of Nature's Red List of Threatened Species, while the Antarctic Minke Whale, Balaenoptera bonaerensis, is considered to Near Threatened, with this diagnosis based upon concerns about disappearing ice sheets in its Antarctic environment rather than the threat presented by Whaling (and is largely based upon data gathered by scientists attached to the Japanese Whaling fleet).

Five species of Whale are currently considered to be Endangered under the terns of the Red List, the Sei Whale, Balaenoptera borealis, the Blue Whale, Balaenoptera musculus, th Fin Whale, the North Atlantic Right Whale, Eubalaena glacialis, and the North Pacific Right Whale, Eubalaena japonica, all of which are large, slow breeding, Baleen Whales, which are not thought to have recovered from former commercial Whaling. Only one of these species, the Fin Whale, is still hunted, with Iceland setting quotas of between 150 and 200 Fin Whales to be taken each year, the meat of which is exported to Japan. However, this hunt is often disrupted by environmental groups such as Sea Shepherd, which sunk two Icelandic Whaling vessels in 1986, and which has succeeded in completely disrupting hunts in other years.

Fifty nine confirmed deaths as Hurricane Maria sweeps across the Caribbean.

Fifty nine people have now been confirmed dead and a further thirty three are still missing after Hurricane Maria swept across the Caribbean this week. The hurricane hit the island of Dominica at about 9.35 pm local time on Monday 18 September 2017 as a Category Five tropical storm when it hit the Leeward Islands, with sustained winds in excess of 250 km per hour and gusts considerably stronger. The storm is known to have killed 27 people here, with another 27 still missing, and caused widespread devastation, with widespread flooding and many of the island's buildings destroyed.

The storm passed to the southwest of the Leeward Islands, but still caused widespread problems there. The island of Guadeloupe was hit by winds in excess of 160 kilometres per hour and waves over six meters high, which led to two fatalities from a fishing boat off the island and widespread damage to buildings and farmland. The storm was also felt in the Lesser Antilles, with the island of Martinique hit by a storm surge, high winds and rains, which have caused extensive damage to crops and buildings and injured two people.

The storm hit Puerto Rico as a Category Four storm, with winds in excess of 210 km per hour and larger gusts. The storm caused widespread flooding on the island, including damage to a number of dams. Several coastal communities have been totally or nearly totally destroyed, and at least 24 people have died, with three people still missing on the island.

The storm passed to the northeast of the Dominican Republic, causing flooding and landslides that killed two people and destroyed around 110 homes. In neighbouring Haiti a further three people were killed. The Storm passed across the island of Saint Croix in the US Virgin islands,causing flooding and damage to buildings, and resulting in one fatality (due to a heart attack).

Tropical storms are caused by the warming effect of the Sun over tropical seas. As the air warms it expands, causing a drop in air pressure, and rises, causing air from outside the area to rush in to replace it. If this happens over a sufficiently wide area then the inrushing winds will be affected by centrifugal forces caused by the Earth's rotation (the Coriolis effect). This means that winds will be deflected clockwise in the northern hemisphere and anti-clockwise in the southern hemisphere, eventually creating a large, rotating Tropical Storm. They have different names in different parts of the world, with those in the northwest Atlantic being referred to as hurricanes.

Despite the obvious danger of winds of this speed, which can physically blow people, and other large objects, away as well as damaging buildings and uprooting trees, the real danger from these storms comes from the flooding they bring. Each drop millibar drop in air-pressure leads to an approximate 1 cm rise in sea level, with big tropical storms capable of causing a storm surge of several meters. This is always accompanied by heavy rainfall, since warm air over the ocean leads to evaporation of sea water, which is then carried with the storm. These combined often lead to catastrophic flooding in areas hit by tropical storms.

Tropical Storm Erika kills at least 25 in the Caribbean.

At least 36 people are known to have died and over 50 more are missing after Tropical Storm Erika swept across the islands of Dominica, Puerto Rico and Hispaniola this week. On Thursday 27 August the storm swept across the island of Dominica, bringing 38 cm of rain within 24 hours and causing widespread flooding and a number of landslides. Landslides are a common problem after severe weather events, as excess pore water pressure can overcome cohesion in soil and sediments, allowing them to flow like liquids. Approximately 90% of all landslides are caused by heavy rainfall. Twenty people have been confirmed dead on the island, and at least 31 more are known to be missing, with the death toll likely to rise as contact is made with remote parts of the mountainous country, where much of the transport infrastructure has been knocked out.

After leaving Dominica the storm next passed over Puerto RIco, where power to around 200 000 households was cut, and crops with an estimated value of US$16 million, then the southern tip of Hispaniola, where it caused further flooding and at least five deaths. One person died in a landslide to the north of Port-au-Prince in Haiti, and four more were killed and another eleven injured after a truck carrying clairin (a form of raw liquor distilled from cane sugar) crashed into a bus shelter in heavy rain at Leogane and reportedly exploded.

Following its passage across southern Hispaniola the storm passed over the eastern part of Cuba, where it brought around two hours of heavy rain around the city of Santiago, prompting authorities to evacuate around 2000 people from low-lying areas.
