WORLD METEOROLOGICAL DAY: WHY IT SHOULD BE CELEBRATED
Increased concern of human beings about the environment in the few last decades has encouraged several organizations to fight and plan events in order to spread awareness about environment pollution and its consequences in life conditions and moreover in weather settings.
The Founding of World Meteorological Organization
Although, many people would believe that these concerns are from recent dates, one of the most important organizations related to this topic – The World Meteorological Organization – was founded in 1873 as the International Meteorological Organization during the International Meteorological Convention in Vienna. However, it was not ratified until 1950 by the WMO Convention on March 23th by the United Nations. A year later the organization had become the specialised agency for the UN for meteorology, operational hydrology and geophysical sciences. This organization was established with the purpose of instituting big meteorological stations networks to contribute towards the safety and efficiency of the shipping services as well as safety and welfare of people. Working worldwide on an international level, the WMO has worked continuously for the growth and development of the meteorological and operational hydrological research activities without boundaries limiting its scope of action.
Establishment of World Meteorological Day
Due to the importance of the main theme of the organization, the United Nations established March 23th as the World Meteorological Day to remember the fact of the official recognition of the WMO. This celebration has been officially celebrated for the first time in 1961 with different topics as main themes every single year since that first event.
Celebrating World Meteorological Day
In 2018, the theme taken as a principal topic is Understanding Clouds, with the event being based in Uganda. Many different activities are organised for the occasion, among them are several scientific and technical forums, conferences, exhibitions, symposiums, and debates related to the main subject.
Although, the celebration varies its location every single year; the day is feted worldwide with activities similar to those taken place in the principal location. In India, essay and composition competitions are held related to the World Meteorological Day. Also, in the headquarters of WMO, located in Geneva, discussions are held about its scope through history and the implementation of future events to mark this day among people who still have no clue about it.
Furthermore, many countries print postage stamps or special postage stamp cancellation to celebrate this day. Several awards are presented on this day to people and organizations involved in the Meteorological field. Among the prizes included in the celebration are: the International Meteorological Organization Prize, Professor Dr. Vilho Väisälä and the Nobert Gerbier-Mumm International Awards.
Since the environmental and nature concern has been growing into international level, the prominence of this celebration has been taken into consideration more and more among several countries; even though there are some big developed countries which deny the importance of this organization in recent years.
Besides the negative concern from very few countries, the WMO is established to continue generate possible solutions and plans to make the world a better place.
The Significance EARTH DAY
April is the time of the year when our news feeds and social media walls get crowded with videos and posts related to the World Earth Day campaigns. While it might seem to be a largely fresh idea, the Earth Day celebrations have actually been around for the last 48 years! Right from the year 1970, every 22nd April is ear-marked as the World Earth Day.
The Significance of Earth Day
The annual Earth Day event is all about devoting a special day to the planet we live in. It intends to spread awareness among the masses about the need for the conservation of natural resources and the protection of the environment. The Earth Day celebrations have an extensive global reach with recognition from about 193 countries in the world. The leaders and rulers from different parts of the globe express their solidarity over preservation and protection of the planet. The Earth Day is celebrated to remind us of the importance of our world and its ecosystems and the need to promote harmony between man and nature.
The Origin Story of Earth Day
The first thoughts on a concept similar to Earth Day came into the reckoning after the disastrous Saint Barbara oil spill back in 1969. Peace activist John McConnell advanced the idea in the 1969 San Francisco UNESCO conference and the event was scooped-up by US college students and environmentalists. The United States Senator Gaylord Nelson is credited as the organizer of the first Earth Day event on 22nd April 1970.
Earth Day Theme for 2020
The theme of Earth Day this year is Climate Action. The activities include raising awareness about the accelerating rate of extinction of millions of species and the causes and consequences of this phenomenon. Other activities include building a global movement to embrace nature and encourage individuals to adopt eco-friendly habits.
Last year the theme was ‘Protect Our Species’. The 2018 theme was ‘End Plastic Pollution’. The events and campaigns organized were focused on encouraging people to reduce plastic consumption and to urge them to use other eco-friendly substitutes. People across the globe are advised to use reusable bags, bottles, and cups and to avoid the usage of plastic straws and other disposable containers.
How to do your bit for the Earth Day?
It doesn’t seem to be too hard to contribute to the cause! You can play a part in the campaign by simply planting a tree or making a friend aware of the need to replace plastic with other bio-degradable alternatives. Tidying up your surroundings and trying to save resources are a few other options you could go for. But, the Earth Day isn’t just about spreading awareness and the key is in taking some solid action to protect it as well.
