Sarnia vs Helsingborg

Informations

Sarnia is a city in Southwestern Ontario, Canada, with a 2016 population of 71,594. It is the largest city on Lake Huron and in Lambton County. Sarnia is located on the eastern bank of the junction between the Upper and Lower Great Lakes where Lake Huron flows into the St. Clair River, which forms the Canada–United States border, directly across from Port Huron, Michigan. The site's natural harbour first attracted the French explorer La Salle. He named the site "The Rapids" on 23 August 1679, when he had horses and men pull his 45-ton barque Le Griffon north against the nearly four-knot current of the St. Clair River.This was the first time that a vessel other than a canoe or other oar-powered vessel had sailed into Lake Huron, and La Salle's voyage was germinal in the development of commercial shipping on the Great Lakes. Located in the natural harbour, the Sarnia port remains an important centre for lake freighters and oceangoing ships carrying cargoes of grain and petroleum products. The natural port and the salt caverns that exist in the surrounding areas, together with the oil discovered in nearby Oil Springs in 1858, led to the dramatic growth of the petroleum industry in this area.

Because Oil Springs was the first place in Canada and North America to drill commercially for oil, the knowledge that was acquired there resulted in oil drillers from Sarnia travelling the world teaching other enterprises and nations how to drill for oil.The complex of refining and chemical companies is called Chemical Valley and located south of downtown Sarnia. In 2011 the city had the highest level of particulates air pollution of any Canadian city, but it has since dropped to rank 30th in this hazard. About 60 percent of the particulate matter comes from industries and polluters in the neighbouring United States.Lake Huron is cooler than the air in summer and warmer than the air in winter; therefore, it moderates Sarnia's humid continental climate, making temperature extremes of hot and cold less evident. In the winter, Sarnia occasionally experiences lake-effect snow from Arctic air blowing across the warmer waters of Lake Huron and condensing to form snow squalls over land.

Helsingborg (, US also , Swedish: [hɛlsɪŋˈbɔrj] (listen), Danish: [helse̝ŋˈpɒˀ]; spelled Hälsingborg between 1912 and 1970) is a town and the seat of Helsingborg Municipality, Scania, Sweden. It had 112,496 inhabitants in 2019. Helsingborg is the centre of the northern part of western Scania and Sweden's closest point to Denmark: the Danish city Helsingør is clearly visible about 4 km (2 mi) to the west on the other side of the Øresund. The HH Ferry route across the sound has more than 70 car ferry departures from each harbour every day.Following the Swedish orthography reform of 1906 the spelling of many place names in Sweden was modernized. In 1912 it was decided to use the form Hälsingborg.

In preparation for the local government reform in 1971, Hälsingborg city council proposed that the new, enlarged municipality should be spelled Helsingborg; this form was adopted by the government of Sweden from 1 January 1971. Historic Helsingborg, with its many old buildings, is a scenic coastal city. The buildings are a blend of old-style stone-built churches and a 600-year-old medieval fortress (Kärnan) in the city centre, and more modern commercial buildings. The streets vary from wide avenues to small alley-ways. Kullagatan, the main pedestrian shopping street in the city, was the first pedestrian shopping street in Sweden.
