Informations

Abu Dhabi (UK:, US:; Arabic: أَبُو ظَبْيٍ‎ Abū Ẓaby Arabic pronunciation: [ɐˈbuˈðˤɑbi]) is the capital and the second-most populous city of the United Arab Emirates (later Dubai). The city of Abu Dhabi is located on an island in the Persian Gulf, off the Central West Coast. The Majority of the city and the Emirate live on the mainland connected to the rest of the country. As of 2020, Abu Dhabi's urban area had an estimated population of 1.48 million, out of 2.9 million in the emirate of Abu Dhabi, as of 2016. Abu Dhabi homes local and national government offices and is the home of the United Arab Emirates Government and the Supreme Petroleum Council.

The city is home to the President of the UAE, who's a member of the Al Nahyan family. Abu Dhabi's rapid development and urbanization, coupled with the gigantic oil and gas reserves and production and relatively high average income, have transformed it into a big, developed metropolis. It's the nation's center of politics and business, and a significant culture and commerce center. Abu Dhabi accounts for approximately two-thirds of the approximately $400 billion UAE economy.

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.
