Seperated by 3.8 kms with a time difference of 20 hours

The 19th century was an era of standardization. As railways were connecting whole landmasses, countries were supplanting nearby occasions with an arrangement of hour-wide time regions. As sea navigation became more common, and since there was no common time agreed, sailors faced a lot of difficulties. As a result, many countries decided to standardize on a system of navigation and maps. They all came together and met in Washington DC for the International Meridian Conference to accept on standard time. There were 41 delegates from 25 countries who attended the International Meridian Conference. Many countries including the US, even before the Conference started using Greenwich as the basis for their time zone system. Additionally, 72% of the world's trade at the time relied upon ocean graphs, which had just embraced Greenwich as the prime meridian. So, countries just adopted the British standard time as an official at the Meridian Conference. In this way, the Prime Meridian at Greenwich became the center of world time.

In Greenwich, the line passes through the Airy Transit in Royal Observatory. The Royal Observatory in Greenwich is where east meets west at Longitude 0°. The prime meridian for the entire world goes through the eyepiece of the Airy telescope. The Airy travel circle can be utilized to make two estimations - the time at which a star crosses the meridian, as it ventures out from East to West over the sky, and the point of the star over the skyline. As the Earth's outside is moving somewhat constantly the specific situation of the Prime Meridian is presently moving marginally as well, however, the first reference for the prime meridian of the world remains the Airy Transit Circle in the Royal Observatory, regardless of whether the specific area of the line may move to either side of Airy's meridian.

The universal dateline likewise denotes the fringe among Russia and the United States. There are two islands Big Diomede and Little Diomede which are situated in the middle of the Bering Strait. People from Little Diomede can see Big Diomede easily as they are separated only by a distance of about 3.8 km. The important point here is that the time difference between these two islands is huge. Big Diomede which is a Russian territory is 20 hours ahead of Little Diomede, which is an American territory. Big Diomede is uninhabited with only research works undertaken by the Russian Government taking place there, whereas Little Diomede is Inhabitat with its permanent residents.

Though people from little Diomede can see Big Diomede easily, the time difference between these two islands is huge because the International Date Line passes between these two islands. Big Diomede is situated at the west of the International Dateline meanwhile Little Diomede is on the East. This is the reason, Big Diomede is far ahead than Little Diomede.

The transition zone between the Pacific and Arctic seas is the Bering Sea. It has seen an emotional loss of winter ice. The Arctic district temperatures are increasing at a fast rate which is more than twice that of the areas at lower scopes. The recurrence of downpour on-snow occasions is expanding over the Arctic which all the while will effectively affect living creatures close to the spot. As a result of its basic situation on the planet, the quickly changing Bering Sea is a sentinel of Arctic environmental change. The islands of Little and Big Diomede are additionally of no exemption.

These islands are one of the first for experiencing the impacts of climate change. The temperature in this region is keeping on increasing and as a result, the Bering sea which will be covered with ice is nowadays seen as a normal warm water sea.

The impacts of Climate Change are now being faced by many of the places in the Arctic and Oceania. Many tiny nations will vanish in decades if this situation continues. If we allow this situation to continue then after the vanishing of tiny countries large countries will also be threatened and will start to lose their land area. So, meetings have to be arranged between countries and steps have to be taken at the Conference for saving these countries which ultimately saves large nations too
