Sarnia vs Warsaw

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.

Warsaw ( WOR-saw; Polish: Warszawa [varˈʂava] (listen); see also other names) is the capital and largest city of Poland. The metropolis stands on the Vistula River in east-central Poland and its population is officially estimated at 1.8 million residents within a greater metropolitan area of 3.1 million residents, which makes Warsaw the 7th most-populous capital city in the European Union. The city limits cover 517.24 square kilometres (199.71 sq mi), while the metropolitan area covers 6,100.43 square kilometres (2,355.39 sq mi). Warsaw is an alpha- global city, a major international tourist destination, and a significant cultural, political and economic hub. Its historical Old Town was designated a UNESCO World Heritage Site. The city rose to prominence in the late 16th century, when Sigismund III decided to move the Polish capital and his royal court from Kraków. The elegant architecture, grandeur and extensive boulevards earned Warsaw the nickname Paris of the North prior to the Second World War. Bombed at the start of the German invasion in 1939, the city withstood a siege, but was largely destroyed by the Warsaw Ghetto Uprising in 1943, the general Warsaw Uprising in 1944 and the systematic razing by the Germans in advance of the Vistula–Oder Offensive. Warsaw gained the new title of Phoenix City because of its complete reconstruction after the war, which had left over 85% of its buildings in ruins.In 2012, the Economist Intelligence Unit ranked Warsaw as the 32nd most liveable city in the world. In 2017, the city came 4th in the "Business-friendly", 8th in "Human capital and life style" and topped the quality of life rankings in the region.

The city is a significant centre of research and development, business process outsourcing and information technology outsourcing. The Warsaw Stock Exchange is the largest and most important in Central and Eastern Europe. Frontex, the European Union agency for external border security as well as ODIHR, one of the principal institutions of the Organization for Security and Cooperation in Europe have their headquarters in Warsaw. Jointly with Frankfurt and Paris, Warsaw features one of the highest number of skyscrapers in the European Union.The city is the seat of the Polish Academy of Sciences, National Philharmonic Orchestra, University of Warsaw, the Warsaw University of Technology, the National Museum, Zachęta Art Gallery and the Warsaw Grand Theatre, the largest of its kind in the world. The picturesque Old Town, which represents examples of nearly every European architectural style and historical period, was listed as a World Heritage Site by UNESCO in 1980. Other main architectural attractions include the Royal Castle and the iconic King Sigismund's Column, the Wilanów Palace, the Palace on the Isle, St. John's Cathedral, Main Market Square as well as numerous churches and mansions along the Royal Route. Warsaw is positioning itself as Central and Eastern Europe's chic cultural capital with thriving art or club scenes and restaurants, with around a quarter of the city's area occupied by parks.
