Paul J. Crutzen
Paul Jozef Crutzen (; 3 December 1933 – 28 January 2021) was a Dutch meteorologist and atmospheric chemist. In 1995, he was awarded the Nobel Prize in Chemistry alongside Mario Molina and Frank Sherwood Rowland for their work on atmospheric chemistry and specifically for his efforts in studying the formation and decomposition of atmospheric ozone. In addition to studying the ozone layer and climate change, he popularized the term Anthropocene to describe a proposed new epoch in the Quaternary period when human actions have a drastic effect on the Earth. He was also amongst the first few scientists to introduce the idea of a nuclear winter to describe the potential climatic effects stemming from large-scale atmospheric pollution including smoke from forest fires, industrial exhausts, and other sources like oil fires. He was a member of the Royal Swedish Academy of Sciences and an elected foreign member of the Royal Society in the United Kingdom. Early life and education Crut ...

Civil Engineering
Civil engineering is a regulation and licensure in engineering, professional engineering discipline that deals with the design, construction, and maintenance of the physical and naturally built environment, including public works such as roads, bridges, canals, dams, airports, sewage systems, pipelines, structural element, structural components of buildings, and railways. Civil engineering is traditionally broken into a number of sub-disciplines. It is considered the second-oldest engineering discipline after military engineering, and it is defined to distinguish non-military engineering from military engineering. Civil engineering can take place in the public sector from municipal public works departments through to federal government agencies, and in the private sector from locally based firms to Fortune Global 500, ''Fortune'' Global 500 companies.

Hogere Burgerschool
The ''Hogere Burgerschool'' (''HBS'') (Dutch: Higher Civic School) was a secondary school type that existed between 1863 and 1974 in the Netherlands and the Dutch Empire. These schools, with a five- or sometimes six-year program, continued in 1968 as VWO. The last HBS diplomas were given out in 1974. History The HBS is a mid-19th-century creation by the liberal politician Johan Rudolph Thorbecke, and resulted from the law on secondary education enacted in May 1863. Along with the creation of ''burgerscholen'' in each city of more than 10,000 inhabitants, the HBS was intended as a practically oriented education for higher functions in industry and trade. It was explicitly not intended as a sufficient education to enter university. According to historian Hans Verhage the form "''hogere-burgerschool''" (the hyphen indicating that ''hogere'', "higher", modifies ''burger'', "citizen") is linguistically correct, since it was a schooling system geared toward higher-ranked citizens, a ...

Dutch Famine Of 1944–1945
The Dutch famine of 1944–1945, also known as the Hunger Winter (from Dutch language, Dutch ''Hongerwinter''), was a famine that took place in the History of the Netherlands (1939–1945), German-occupied Netherlands, especially in the densely populated western provinces north of the great rivers, during the relatively harsh winter of 1944–1945, near the end of World War II. A German blockade cut off food and fuel shipments from farm towns. Some 4.5 million were affected and survived thanks to soup kitchens. Loe de Jong (1914–2005), author of ''The Kingdom of the Netherlands During World War II'', estimated at least 22,000 deaths occurred due to the famine. Another author estimated 18,000 deaths from the famine. Most of the victims were reportedly elderly men. The famine was alleviated first by "Swedish bread" flour shipped in from Sweden to Dutch harbours, and subsequently by the airlift of food by the Royal Air Force, the Royal Canadian Air Force, and the United ...

Nuclear Winter
Nuclear winter is a severe and prolonged anti-greenhouse effect, global climatic cooling effect that is hypothesized to occur after widespread firestorms following a large-scale Nuclear warfare, nuclear war. The hypothesis is based on the fact that such fires can inject soot into the stratosphere, where it can block some Diffuse sky radiation, direct sunlight from reaching the surface of the Earth. It is speculated that the resulting cooling would lead to widespread crop failure and Nuclear famine, famine. When developing computer models of nuclear-winter scenarios, researchers use the conventional bombing of Hamburg, and the Atomic bombings of Hiroshima and Nagasaki, Hiroshima firestorm in World War II as example cases where soot might have been injected into the stratosphere, alongside modern observations of natural, large-area wildfire-firestorms. General "Nuclear winter", or as it was initially termed, "nuclear twilight", began to be considered as a scientific concept in th ...

Climate Change
Present-day climate change includes both global warming—the ongoing increase in Global surface temperature, global average temperature—and its wider effects on Earth's climate system. Climate variability and change, Climate change in a broader sense also includes previous long-term changes to Earth's climate. The current rise in global temperatures is Scientific consensus on climate change, driven by human activities, especially fossil fuel burning since the Industrial Revolution. Fossil fuel use, Deforestation and climate change, deforestation, and some Greenhouse gas emissions from agriculture, agricultural and Environmental impact of concrete, industrial practices release greenhouse gases. These gases greenhouse effect, absorb some of the heat that the Earth Thermal radiation, radiates after it warms from sunlight, warming the lower atmosphere. Carbon dioxide, the primary gas driving global warming, Carbon dioxide in Earth's atmosphere, has increased in concentratio ...

Ozone Layer
The ozone layer or ozone shield is a region of Earth's stratosphere that absorption (electromagnetic radiation), absorbs most of the Sun's ultraviolet radiation. It contains a high concentration of ozone (O3) in relation to other parts of the atmosphere, although still small in relation to other gases in the stratosphere. The ozone layer peaks at 8 to 15 parts per million of ozone, while the average ozone concentration in Earth's atmosphere as a whole is about 0.3 parts per million. The ozone layer is mainly found in the lower portion of the stratosphere, from approximately above Earth, although its thickness varies seasonally and geographically. The ozone layer was discovered in 1913 by French physicists Charles Fabry and Henri Buisson. Measurements of the sun showed that the radiation sent out from its surface and reaching the ground on Earth is usually consistent with the spectrum of a black body with a temperature in the range of , except that there was no radiation below a ...

Atmospheric Chemistry
Atmospheric chemistry is a branch of atmospheric science that studies the chemistry of the Earth's atmosphere and that of other planets. This multidisciplinary approach of research draws on environmental chemistry, physics, meteorology, computer modeling, oceanography, geology and volcanology, climatology and other disciplines to understand both natural and human-induced changes in atmospheric composition. Key areas of research include the behavior of trace gasses, the formation of pollutants, and the role of aerosols and greenhouse gasses. Through a combination of observations, laboratory experiments, and computer modeling, atmospheric chemists investigate the causes and consequences of atmospheric changes. Atmospheric composition The composition and chemistry of the Earth's atmosphere is important for several reasons, but primarily because of the interactions between the atmosphere and living organisms. Natural processes such as volcano emissions, lightning and bombardme ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
