Earth Hour
Earth Hour is a worldwide movement organized by the World Wide Fund for Nature, World Wildlife Fund (WWF). The event is held annually, encouraging the individuals, communities, and businesses to give an hour for Earth, and additionally marked by landmarks and businesses switching off non-essential electric lights, for one hour from 8:30 to 9:30 p.m., usually on the last Saturday of March, as a symbol of commitment to the planet. It was started as a lights-off event in Sydney, Australia, in 2007. Occasionally, in years when Holy Saturday falls on the last Saturday of March (as in 2024), Earth Hour is held a week earlier. History of Earth Hour Conception and start: 2004–2007 In 2004, confronted with scientific findings, WWF Australia met with advertising agency Leo Burnett Worldwide, Leo Burnett Sydney to "discuss ideas for engaging Australians on the issue of climate change". The idea of a large scale switch off was coined and developed in 2006, originally under th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Earth Day
Earth Day is an annual event on April 22 to demonstrate support for environmental protection. First held on April 22, 1970, it now includes a wide range of events coordinated globally through earthday.org (formerly Earth Day Network) including 1 billion people in more than 193 countries. In 1969 at a UNESCO conference in San Francisco, peace activist John McConnell (peace activist), John McConnell proposed a day to honor the Earth and the concept of peace, to first be observed on March 21, 1970, the Spring (season)#Astronomical and solar reckoning, first day of spring in the northern hemisphere. This day of nature's equipoise was later sanctioned in a proclamation written by McConnell and signed by Secretary General U Thant at the United Nations. A month later, United States senator Gaylord Nelson proposed the idea to hold a nationwide environmental teach-in on April 22, 1970, and hired a young activist, Denis Hayes, to be the national coordinator. The name "Earth Day" wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Shabbat
Shabbat (, , or ; , , ) or the Sabbath (), also called Shabbos (, ) by Ashkenazi Hebrew, Ashkenazim, is Judaism's day of rest on the seventh day of the seven-day week, week—i.e., Friday prayer, Friday–Saturday. On this day, religious Jews remember the biblical stories describing the Genesis creation narrative, creation of the heaven and earth in six days and the redemption from slavery and the Exodus from Egypt. Since the Hebrew calendar, Jewish religious calendar counts days from sunset to sunset, Shabbat begins in the evening of what on the civil calendar is Friday. Shabbat observance entails refraining from 39 Melachot, work activities, often with shomer Shabbat, great rigor, and engaging in restful activities to honor the day. Judaism's traditional position is that the unbroken seventh-day Shabbat originated among the Jewish people, as their first and most sacred institution. Variations upon Shabbat are widespread in Judaism and, with adaptations, throughout the Abraham ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Bangkok Post
The ''Bangkok Post'' is an English-language daily newspaper published in Bangkok, Thailand. It is published in broadsheet and digital formats. The first issue was sold on 1 August 1946. It had four pages and cost one baht, a considerable amount at the time when a baht was a paper note. It is Thailand's oldest newspaper still in publication. The daily circulation of the ''Bangkok Post'' is 110,000, 80 percent of which is distributed in Bangkok and the remainder nationwide. It is considered a newspaper of record for Thailand. From July 2016 until mid-May 2018, the editor of the ''Bangkok Post'' was Umesh Pandey. On 14 May 2018, Pandey was "forced to step down" as editor after refusing to soften coverage critical of the ruling military junta. History The ''Bangkok Post'' was founded by Alexander MacDonald, a former OSS officer, and his Thai associate, Prasit Lulitanond. Thailand at the time was the only Southeast Asian country to have a Soviet Embassy. The U.S. embassy felt it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Carbon Dioxide Emission
Greenhouse gas (GHG) emissions from human activities intensify the greenhouse effect. This contributes to climate change. Carbon dioxide (), from burning fossil fuels such as coal, petroleum, oil, and natural gas, is the main cause of climate change. The top contributors to greenhouse gas emissions, largest annual emissions are from China followed by the United States. The United States has List of countries by greenhouse gas emissions per capita, higher emissions per capita. The main producers fueling the emissions globally are Big Oil, large oil and gas companies. Emissions from human activities have increased Carbon dioxide in Earth's atmosphere, atmospheric carbon dioxide by about 50% over pre-industrial levels. The growing levels of emissions have varied, but have been consistent among all greenhouse gases. Emissions in the 2010s averaged 56 billion tons a year, higher than any decade before. Total cumulative emissions from 1870 to 2022 were 703 (2575 ), of which 484±20 (177 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Megawatt-hours
A kilowatt-hour (unit symbol: kW⋅h or kW h; commonly written as kWh) is a non-SI unit of energy equal to 3.6 megajoules (MJ) in SI units, which is the energy delivered by one kilowatt of power for one hour. Kilowatt-hours are a common billing unit for electrical energy supplied by electric utilities. Metric prefixes are used for multiples and submultiples of the basic unit, the watt-hour (3.6 kJ). Definition The kilowatt-hour is a composite unit of energy equal to one kilowatt (kW) multiplied by (i.e., sustained for) one hour. The International System of Units (SI) unit of energy meanwhile is the joule (symbol J). Because a watt is by definition one joule per second, and because there are 3,600 seconds in an hour, one kWh equals 3,600 kilojoules or 3.6 MJ."Half-high dots or spaces are used to express a derived unit formed from two or more other units by multiplication.", Barry N.

Carbon Dioxide
Carbon dioxide is a chemical compound with the chemical formula . It is made up of molecules that each have one carbon atom covalent bond, covalently double bonded to two oxygen atoms. It is found in a gas state at room temperature and at normally-encountered concentrations it is odorless. As the source of carbon in the carbon cycle, atmospheric is the primary carbon source for life on Earth. In the air, carbon dioxide is transparent to visible light but absorbs infrared, infrared radiation, acting as a greenhouse gas. Carbon dioxide is soluble in water and is found in groundwater, lakes, ice caps, and seawater. It is a trace gas Carbon dioxide in Earth's atmosphere, in Earth's atmosphere at 421 parts per million (ppm), or about 0.042% (as of May 2022) having risen from pre-industrial levels of 280 ppm or about 0.028%. Burning fossil fuels is the main cause of these increased concentrations, which are the primary cause of climate change.IPCC (2022Summary for pol ...

Tonnes
The tonne ( or ; symbol: t) is a unit of mass equal to 1,000 kilograms. It is a non-SI unit accepted for use with SI. It is also referred to as a metric ton in the United States to distinguish it from the non-metric units of the short ton ( United States customary units) and the long ton ( British imperial units). It is equivalent to approximately 2,204.6 pounds, 1.102 short tons, and 0.984 long tons. The official SI unit is the megagram (Mg), a less common way to express the same amount. Symbol and abbreviations The BIPM symbol for the tonne is t, adopted at the same time as the unit in 1879.Table 6 . BIPM. Retrieved on 2011-07-10. Its use is also official for the metric ton in the United States, having been adopted by the United States |

Megawatts
The watt (symbol: W) is the unit of power or radiant flux in the International System of Units (SI), equal to 1 joule per second or 1 kg⋅m2⋅s−3. It is used to quantify the rate of energy transfer. The watt is named in honor of James Watt (1736–1819), an 18th-century Scottish inventor, mechanical engineer, and chemist who improved the Newcomen engine with his own steam engine in 1776, which became fundamental for the Industrial Revolution. Overview When an object's velocity is held constant at one meter per second against a constant opposing force of one newton, the rate at which work is done is one watt. \mathrm. In terms of electromagnetism, one watt is the rate at which electrical work is performed when a current of one ampere (A) flows across an electrical potential difference of one volt (V), meaning the watt is equivalent to the volt-ampere (the latter unit, however, is used for a different quantity from the real power of an electrical circuit). ...

Colosseum Earth Hour
The Colosseum ( ; , ultimately from Ancient Greek word "kolossos" meaning a large statue or giant) is an Ellipse, elliptical amphitheatre in the centre of the city of Rome, Italy, just east of the Roman Forum. It is the largest ancient amphitheatre ever built, and is still the largest standing amphitheatre in the world, despite its age. Construction began under the Emperor Vespasian () in 72 and was completed in AD 80 under his successor and heir, Titus (). Further modifications were made during the reign of Domitian (). The three emperors who were patrons of the work are known as the Flavian dynasty, and the amphitheatre was named the Flavian Amphitheatre (; ) by later classicists and archaeologists for its association with their family name (Flavia (gens), Flavius). The Colosseum is built of travertine#Uses, travertine limestone, tuff (volcanic rock), and brick-faced Roman concrete, concrete. It could hold an estimated 50,000 to 80,000 spectators at various points in its h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
