Deforestation
–
Deforestation, clearance or clearing is the removal of a forest or stand of trees where the land is thereafter converted to a non-forest use. Examples of deforestation include conversion of forestland to farms, ranches, the most concentrated deforestation occurs in tropical rainforests. About 30% of Earths land surface is covered by forests, Deforestation occurs for multiple reasons, trees are cut down to be used for building or sold as fuel, while cleared land is used as pasture for livestock and plantation. The removal of trees without sufficient reforestation has resulted in damage to habitat, biodiversity loss and it has adverse impacts on biosequestration of atmospheric carbon dioxide. Deforestation has also used in war to deprive the enemy of cover for its forces. Modern examples of this were the use of Agent Orange by the British military in Malaya during the Malayan Emergency, as of 2005, net deforestation rates have ceased to increase in countries with a per capita GDP of at least US$4,600. Deforested regions typically incur significant adverse soil erosion and frequently degrade into wasteland, disregard of ascribed value, lax forest management and deficient environmental laws are some of the factors that allow deforestation to occur on a large scale. In many countries, deforestation, both naturally occurring and human-induced, is an ongoing issue, Deforestation causes extinction, changes to climatic conditions, desertification, and displacement of populations as observed by current conditions and in the past through the fossil record. More than half of all plant and land animal species in the live in tropical forests. Between 2000 and 2012,2.3 million square kilometres of forests around the world were cut down, as a result of deforestation, only 6.2 million square kilometres remain of the original 16 million square kilometres of forest that formerly covered the Earth. According to the United Nations Framework Convention on Climate Change secretariat, subsistence farming is responsible for 48% of deforestation, commercial agriculture is responsible for 32%, logging is responsible for 14%, and fuel wood removals make up 5%. Experts do not agree on whether industrial logging is an important contributor to global deforestation, some argue that poor people are more likely to clear forest because they have no alternatives, others that the poor lack the ability to pay for the materials and labour needed to clear forest. One study found that population increases due to fertility rates were a primary driver of tropical deforestation in only 8% of cases. Other causes of contemporary deforestation may include corruption of government institutions, the distribution of wealth and power, population growth and overpopulation. Globalization is often viewed as another cause of deforestation, though there are cases in which the impacts of globalization have promoted localized forest recovery. The degradation of forest ecosystems has also traced to economic incentives that make forest conversion appear more profitable than forest conservation. Some commentators have noted a shift in the drivers of deforestation over the past 30 years, Deforestation is ongoing and is shaping climate and geography. Deforestation is a contributor to global warming, and is cited as one of the major causes of the enhanced greenhouse effect

Indonesia
–
Indonesia, officially the Republic of Indonesia, is a unitary sovereign state and transcontinental country located mainly in Southeast Asia with some territories in Oceania. Situated between the Indian and Pacific oceans, it is the worlds largest island country, with more than seventeen thousand islands. At 1,904,569 square kilometres, Indonesia is the worlds 14th-largest country in terms of area and worlds 7th-largest country in terms of combined sea. It has an population of over 260 million people and is the worlds fourth most populous country. The worlds most populous island, Java, contains more than half of the countrys population, Indonesias republican form of government includes an elected legislature and president. Indonesia has 34 provinces, of which five have Special Administrative status and its capital and countrys most populous city is Jakarta, which is also the most populous city in Southeast Asia and the second in Asia. The country shares land borders with Papua New Guinea, East Timor, other neighbouring countries include Singapore, Vietnam, the Philippines, Australia, Palau, and the Indian territory of the Andaman and Nicobar Islands. Despite its large population and densely populated regions, Indonesia has vast areas of wilderness that support the second highest level of biodiversity. The country has abundant natural resources like oil and natural gas, tin, copper, agriculture mainly produces rice, palm oil, tea, coffee, cacao, medicinal plants, spices and rubber. Indonesias major trading partners are Japan, United States, China, the Indonesian archipelago has been an important region for trade since at least the 7th century, when Srivijaya and then later Majapahit traded with China and India. Local rulers gradually absorbed foreign cultural, religious and political models from the early centuries CE, Indonesian history has been influenced by foreign powers drawn to its natural resources. Indonesia consists of hundreds of native ethnic and linguistic groups. The largest – and politically dominant – ethnic group are the Javanese, a shared identity has developed, defined by a national language, ethnic diversity, religious pluralism within a Muslim-majority population, and a history of colonialism and rebellion against it. Indonesias national motto, Bhinneka Tunggal Ika, articulates the diversity that shapes the country, Indonesias economy is the worlds 16th largest by nominal GDP and the 8th largest by GDP at PPP, the largest in Southeast Asia, and is considered an emerging market and newly industrialised country. Indonesia has been a member of the United Nations since 1950, Indonesia is a member of the G20 major economies and World Trade Organization. The name Indonesia derives from the Greek name of the Indós, the name dates to the 18th century, far predating the formation of independent Indonesia. In 1850, George Windsor Earl, an English ethnologist, proposed the terms Indunesians—and, his preference, in the same publication, one of his students, James Richardson Logan, used Indonesia as a synonym for Indian Archipelago. However, Dutch academics writing in East Indies publications were reluctant to use Indonesia, they preferred Malay Archipelago, the Netherlands East Indies, popularly Indië, the East, and Insulinde

Biodiversity
–
Biodiversity, a contraction of biological diversity, generally refers to the variety and variability of life on Earth. One of the most widely used definitions defines it in terms of the variability within species and it is a measure of the variety of organisms present in different ecosystems. This can refer to genetic variation, ecosystem variation, or species variation within an area, biome, terrestrial biodiversity tends to be greater near the equator, which seems to be the result of the warm climate and high primary productivity. Biodiversity is not distributed evenly on Earth, and is richest in the tropics and these tropical forest ecosystems cover less than 10 per cent of earths surface, and contain about 90 percent of the worlds species. Marine biodiversity tends to be highest along coasts in the Western Pacific, there are latitudinal gradients in species diversity. Biodiversity generally tends to cluster in hotspots, and has been increasing through time, the number and variety of plants, animals and other organisms that exist is known as biodiversity. It is a component of nature and it ensures the survival of human species by providing food, fuel, shelter, medicines. The richness of biodiversity depends on the conditions and area of the region. All species of plants taken together are known as flora and about 300,000 species of plants are known to date, all species of animals taken together are known as fauna which includes birds, mammals, fish, reptiles, insects, crustaceans, molluscs, etc. Rapid environmental changes typically cause mass extinctions, more than 99 percent of all species, amounting to over five billion species, that ever lived on Earth are estimated to be extinct. Estimates on the number of Earths current species range from 10 million to 14 million, of which about 1.2 million have been documented and over 86 percent have not yet been described. More recently, in May 2016, scientists reported that 1 trillion species are estimated to be on Earth currently with only one-thousandth of one percent described, the total amount of related DNA base pairs on Earth is estimated at 5.0 x 1037 and weighs 50 billion tonnes. In comparison, the mass of the biosphere has been estimated to be as much as 4 TtC. In July 2016, scientists reported identifying a set of 355 genes from the Last Universal Common Ancestor of all living on Earth. The age of the Earth is about 4.54 billion years old, there are microbial mat fossils found in 3.48 billion-year-old sandstone discovered in Western Australia. Other early physical evidence of a substance is graphite in 3.7 billion-year-old meta-sedimentary rocks discovered in Western Greenland. More recently, in 2015, remains of life were found in 4.1 billion-year-old rocks in Western Australia. According to one of the researchers, If life arose relatively quickly on Earth, then it could be common in the universe

Brazil
–
Brazil, officially the Federative Republic of Brazil, is the largest country in both South America and Latin America. As the worlds fifth-largest country by area and population, it is the largest country to have Portuguese as an official language. Its Amazon River basin includes a vast tropical forest, home to wildlife, a variety of ecological systems. This unique environmental heritage makes Brazil one of 17 megadiverse countries, Brazil was inhabited by numerous tribal nations prior to the landing in 1500 of explorer Pedro Álvares Cabral, who claimed the area for the Portuguese Empire. Brazil remained a Portuguese colony until 1808, when the capital of the empire was transferred from Lisbon to Rio de Janeiro, in 1815, the colony was elevated to the rank of kingdom upon the formation of the United Kingdom of Portugal, Brazil and the Algarves. Independence was achieved in 1822 with the creation of the Empire of Brazil, a state governed under a constitutional monarchy. The ratification of the first constitution in 1824 led to the formation of a bicameral legislature, the country became a presidential republic in 1889 following a military coup détat. An authoritarian military junta came to power in 1964 and ruled until 1985, Brazils current constitution, formulated in 1988, defines it as a democratic federal republic. The federation is composed of the union of the Federal District, the 26 states, Brazils economy is the worlds ninth-largest by nominal GDP and seventh-largest by GDP as of 2015. A member of the BRICS group, Brazil until 2010 had one of the worlds fastest growing economies, with its economic reforms giving the country new international recognition. Brazils national development bank plays an important role for the economic growth. Brazil is a member of the United Nations, the G20, BRICS, Unasul, Mercosul, Organization of American States, Organization of Ibero-American States, CPLP. Brazil is a power in Latin America and a middle power in international affairs. One of the worlds major breadbaskets, Brazil has been the largest producer of coffee for the last 150 years and it is likely that the word Brazil comes from the Portuguese word for brazilwood, a tree that once grew plentifully along the Brazilian coast. In Portuguese, brazilwood is called pau-brasil, with the word brasil commonly given the etymology red like an ember, formed from Latin brasa and the suffix -il. As brazilwood produces a red dye, it was highly valued by the European cloth industry and was the earliest commercially exploited product from Brazil. The popular appellation eclipsed and eventually supplanted the official Portuguese name, early sailors sometimes also called it the Land of Parrots. In the Guarani language, a language of Paraguay, Brazil is called Pindorama

Tropical rainforest
–
True rainforests are typically found between 10 degrees north and south of the equator, they are a sub-set of the tropical forest biome that occurs roughly within the 28 degree latitudes. Within the World Wildlife Funds biome classification, tropical rainforests are a type of tropical moist broadleaf forest that includes the more extensive tropical seasonal forests. Tropical rainforests can be characterized in two words, hot and wet, mean monthly temperatures exceed 18 °C during all months of the year. Average annual rainfall is no less than 1,680 mm and this high level of precipitation often results in poor soils due to leaching of soluble nutrients in the ground. Tropical rainforests exhibit high levels of biodiversity, around 40% to 75% of all biotic species are indigenous to the rainforests. Rainforests are home to half of all the animal and plant species on the planet. Two-thirds of all flowering plants can be found in rainforests, a single hectare of rainforest may contain 42,000 different species of insect, up to 807 trees of 313 species and 1,500 species of higher plants. Tropical rainforests have been called the worlds largest pharmacy, because over one quarter of natural medicines have been discovered within them and it is likely that there may be many millions of species of plants, insects and microorganisms still undiscovered in tropical rainforests. Tropical rainforests are among the most threatened ecosystems globally due to large-scale fragmentation as a result of human activity, habitat fragmentation caused by geological processes such as volcanism and climate change occurred in the past, and have been identified as important drivers of speciation. However, fast human driven habitat destruction is suspected to be one of the causes of species extinction. Tropical rain forests have been subjected to heavy logging and agricultural clearance throughout the 20th century, tropical rainforests have existed on earth for hundreds of millions of years. Most tropical rainforests today are on fragments of the Mesozoic era supercontinent of Gondwana, the separation of the landmass resulted in a great loss of amphibian diversity while at the same time the drier climate spurred the diversification of reptiles. The division left tropical rainforests located in five regions of the world, tropical America, Africa, Southeast Asia, Madagascar. However, the specifics of the origin of rainforests remain uncertain due to a fossil record. Several biomes comprise the general term tropical forest, Lowland equatorial evergreen rain forests are forests which receive rainfall throughout the year. These true rainforests occur in a belt around the equator, with the largest areas in the Amazon basin of South America, the Congo Basin of Central Africa, Borneo, Mindanao, Indonesia, and New Guinea. Moist tropical seasonal forests receive high rainfall with a warm summer wet season. Some trees in these forests drop some or all of their leaves during the dry season

Old-growth forest
–
Old-growth features include diverse tree-related structures that provide diverse wildlife habitat that increases the biodiversity of the forested ecosystem. The concept of tree structure includes multi-layered canopies and canopy gaps, greatly varying tree heights and diameters. Old-growth forests are valuable, and logging of these forests has been a point of contention between the logging industry and environmentalists. Old-growth forests tend to have trees and standing dead trees, multi-layered canopies with gaps that result from the deaths of individual trees. Depending on the forest, this may take anywhere from a century to several millennia, hardwood forests of the eastern United States can develop old-growth characteristics in one or two generations of trees, or 150–500 years. In British Columbia, Canada, old growth is defined as 120 to 140 years of age in the interior of the province where fire is a frequent and natural occurrence. In British Columbia’s coastal rainforests, old growth is defined as more than 250 years. In Australia, eucalypt trees rarely exceed 350 years of age due to frequent fire disturbance, Forest types have very different development patterns, natural disturbances and appearances. Levels of biodiversity may be higher or lower in old-growth forests compared to that in second-growth forests, depending on circumstances, environmental variables. Logging in old-growth forests is an issue in many parts of the world. Excessive logging reduces biodiversity, affecting not only the old-growth forest itself, a forest in old-growth stage has a mix of tree ages, due to a distinct regeneration pattern for this stage. New trees regenerate at different times from other, because each one of them has different spatial location relative to the main canopy. The mixed age of the forest is an important criterion in ensuring that the forest is a stable ecosystem in the long term. A climax stand that is uniformly aged becomes senescent and degrades within a relatively short time-period to result in a new cycle of forest succession, thus, uniformly aged stands are a less stable ecosystem. Forest canopy gaps are essential in creating and maintaining mixed-age stands, also, some herbaceous plants only become established in canopy openings, but persist beneath an understory. Openings are a result of death due to small impact disturbances such as wind, low-intensity fires. Because old-growth forest is structurally diverse it provides higher-diversity habitat than forests in other stages, thus, sometimes higher biological diversity can be sustained in old-growth forest, or at least a biodiversity that is different from other forest stages. The characteristic topography of much old-growth forest consists of pits and mounds, mounds are caused by decaying fallen trees, and pits by the roots pulled out of the ground when trees fall due to natural causes, including being pushed over by animals

Peat swamp forest
–
Peat swamp forests are tropical moist forests where waterlogged soil prevents dead leaves and wood from fully decomposing. Over time, this creates a layer of acidic peat. Large areas of forests are being logged at high rates. Peat swamp forests are surrounded by lowland rain forests on better-drained soils. Their stability has important implications for climate change, they are among the largest near-surface reserves of terrestrial organic carbon, unfortunately, peat swamp forests, which have ecological importance, are one of the most threatened, yet least studied and most poorly understood biotypes. Since the 1970s, peat swamp forest deforestation and drainage have increased exponentially, in addition, El Niño Southern Oscillation drought and large-scale fires are accelerating peatland devastation. This destruction enhances the decomposition of soil and organic matter, increasing the release to the atmosphere as carbon dioxide. This phenomenon suggests that tropical peatlands have already become a large carbon-dioxide source, about 62% of the world’s tropical peat lands occur in the Indomalaya region. They are unusual ecosystems, with trees up to 70 m high - vastly different from the lands of the north temperate. The spongy, unstable, waterlogged, anaerobic beds of peat can be up to 20 m deep with low pH and low nutrients, the water is stained dark brown by the tannins that leach from the fallen leaves and peat – hence the name blackwater swamps. During the dry season, the peat remains waterlogged and pools remain among the trees, peat formation is a natural carbon sink, carbon is withdrawn out of the system and converted into peat through biological activity. Peat swamp forests originally represented major ecosystems in Indonesia and ranged between 16. 5–27 million hectares, in their original state, Indonesian peat swamp forests released between 0. 01–0.03 Gt of carbon annually. In recent years, however, these important ecosystems have been reduced through deforestation, drainage and their current status as carbon sequestering systems have thus also been reduced significantly. Over the past decade, under the Mega Rice Project, the government of Indonesia has drained over 1 million hectares of the Borneo peat swamp forests for conversion to agricultural land. Between 1996 and 1998, more than 4,000 kilometers of drainage and irrigation channels were dug, the water channels, and the roads and railways built for legal forestry, opened up the region to illegal forestry. In the MRP area, forest cover dropped from 64. 8% in 1991 to 45. 7% in 2000 and it appears that almost all the marketable trees have now been removed from the areas covered by the MRP. What happened was not what had expected, the channels drained the peat forests rather than irrigating them. Where the forests had often flooded up to 2 meters deep in the rainy season, the Indonesian government has now abandoned the MRP

Deforestation in Brazil
–
Brazil once had the highest deforestation rate in the world and in 2005 still had the largest area of forest removed annually. Since 1970, over 600,000 square kilometers of the Amazon rainforest have been destroyed, in 2012, the Amazon was approximately 5.4 million square kilometres, which is only 87% of the Amazons original state. Rainforests have decreased in size due to deforestation. Despite reductions in the rate of deforestation in the last ten years, between May 2000 and August 2006, Brazil lost nearly 150,000 square kilometres of forest, an area larger than that of Greece. According to the Living Planet Report 2010, deforestation is continuing at an alarming rate, in the 1940s Brazil began a program of national development for the Amazon Basin. Everything which has up to now been done in Amazonas, whether in agriculture or extractive industry, must be transformed into rational exploitation. Extensive transportation projects, such as the Trans-Amazon Highway, were promoted in 1970, before the 1960s, much of the forest remained intact due to the restrictions in access to the Amazon aside from partial clearing along the river banks. The poor soil also made plantation-based agriculture unprofitable, the key point in deforestation of the Amazon was when the colonists established farms within the forest during the 1960s. Their farming system was based on cultivation and the slash. The colonists were unable to manage their fields and the crops due to the loss of soil fertility. The soils in the Amazon are productive for just a short period of time. However, the results of farming have led to deforestation and have caused extensive environmental damage. This emphasizes the importance of using previously cleared land for agricultural use, in the Brazilian Amazon, the number of small farmers versus large landholders changes frequently with economic and demographic pressures. This act paved the way for clearing areas of forest for cattle production as developers sought to gain a financial profit from land with which they were provided. The forest was also exploited for timber, which provided Brazil a way of paying off international debt, by the late 1980s, an area the size of England, Scotland and Wales was being removed annually. The annual rate of deforestation in the Amazon region has continued to increase from 1990 to 2003 because of factors at local, national, 70% of formerly forested land in the Amazon, and 91% of land deforested since 1970, is used for livestock pasture. The Brazilian government initially attributed 38% of all forest loss between 1966 and 1975 to large-scale cattle ranching, the removal of forest to make way for cattle ranching was the leading cause of deforestation in the Brazilian Amazon from the mid-1960s. Cattle Ranching is not an environmental investment though, cattle emit large amounts of methane into the environment

Susilo Bambang Yudhoyono
–
Susilo Bambang Yudhoyono GCB AC DUT is an Indonesian politician and retired Army general officer who was the President of Indonesia from 2004 to 2014. He is currently the chairman of the Democratic Party of Indonesia and President of the Assembly, Yudhoyono won the 2004 presidential election, defeating incumbent President Megawati Sukarnoputri. Widely known in Indonesia by his initials SBY, he was sworn into office on 20 October 2004 and he was born in Tremas, a village in Arjosari, Pacitan Regency, East Java, to a lower-middle-class family and is the son of Raden Soekotjo and Siti Habibah. His name is Javanese, with Sanskrit roots, Susilo comes from the words su-, meaning good and -sila, meaning behaviour, conduct or moral. Bambang is a male name in Javanese, meaning knight. Yudhoyono comes from the words yuddha -meaning battle, fight, and yana, thus his name roughly translates to well behaved knight. Yudhoyono had wanted to join the army since he was a child, in school, he developed a reputation as an academic achiever, excelling in writing poems, short stories, and play-acting. Yudhoyono was also talented in music and sport, reflected when he and his friends established a club called Klub Rajawali. When he was in grade, Yudhoyono visited the Indonesian Armed Forces Academy. After seeing the training there and perhaps inspired by his own fathers career, Yudhoyono became determined to join Indonesian Armed Forces. Yudhoyono planned to enlist after graduating high school in 1968, however. There, he was able to prepare everything for the phase of his education at Akabri. Yudhoyono officially entered AKABRI in 1970 after passing the test in Bandung, Yudhoyono spent three years at Indonesian Armed Forces Academy and became the Commander of the Cadet Corps Division there. He graduated from AKABRI as second lieutenant in 1973, and as the best graduate of the year, after graduating, Yudhoyono joined the Army Strategic Reserve and became a platoon commander in the 330th Airborne Battalion. Aside from leading his troops, Yudhoyono was also tasked with giving the battalion soldiers lessons on general knowledge, Yudhoyonos proficiency in English was one of the reasons why he was sent to the United States to undertake the Airborne and Ranger Courses at Fort Benning in 1975. Yudhoyono returned to Indonesia in 1976 where he became a commander in the 305th Battalion. Yudhoyono had several tours of duty there and, like many other Indonesian officers involved in the occupation of East Timor, was accused of committing war crimes, however, Yudhoyono has never been charged with any specific act. From East Timor, Yudhoyono became a platoon commander in 1977, an operations officer for an airborne brigade from 1977 to 1978

Borneo
–
Borneo is the third-largest island in the world and the largest island in Asia. At the geographic centre of Maritime Southeast Asia, in relation to major Indonesian islands, it is located north of Java, west of Sulawesi, the island is politically divided among three countries, Malaysia and Brunei in the north, and Indonesia to the south. Approximately 73% of the island is Indonesian territory, in the north, the East Malaysian states of Sabah and Sarawak make up about 26% of the island. Additionally, the Malaysian federal territory of Labuan is situated on an island just off the coast of Borneo. The sovereign state of Brunei, located on the north coast, antipodal to an area of Amazon rainforest, Borneo is itself home to one of the oldest rainforests in the world, and to Bornean orangutans. The island is known by names, internationally it is known as Borneo, after Brunei. The name Brunei possibly was derived from the Sanskrit word váruṇa, meaning either ocean or the mythological Varuna. Indonesian natives called it Kalimantan, which was derived from the Sanskrit word Kalamanthana, prior to that the island was also known by other names. In 977 Chinese records began to use the term Po-ni to refer to Borneo or Brunei, in 1225 it was also mentioned by the Chinese official Chau Ju-Kua. The Javanese manuscript Nagarakretagama, written by Majapahit court poet Mpu Prapanca in 1365, mentioned the island as Nusa Tanjungnagara, to the west of Borneo are the Malay Peninsula and Sumatra. To the south and east are islands of Indonesia, Java and Sulawesi, to the northeast are the Philippine Islands. With an area of 743,330 square kilometres, it is the third-largest island in the world and its highest point is Mount Kinabalu in Sabah, Malaysia, with an elevation of 4,095 m. The largest river system is the Kapuas in West Kalimantan, with a length of 1,143 km, other major rivers include the Mahakam in East Kalimantan, the Barito in South Kalimantan, and Rajang in Sarawak. Clearwater Cave, for example, has one of the worlds longest underground rivers, deer Cave is home to over three million bats, with guano accumulated to over 100 metres deep. The South China Sea and Gulf of Thailand now submerge the former low-lying areas of the peninsula, the Borneo rainforest is 140 million years old, making it one of the oldest rainforests in the world. There are about 15,000 species of flowering plants with 3,000 species of trees,221 species of mammals and 420 species of resident birds in Borneo. There are about 440 freshwater fish species in Borneo and it is the centre of the evolution and distribution of many endemic species of plants and animals. The Borneo rainforest is one of the few remaining habitats for the endangered Bornean orangutan

Climate change
–
Climate change is a change in the statistical distribution of weather patterns when that change lasts for an extended period of time. Climate change may refer to a change in weather conditions. Climate change is caused by such as biotic processes, variations in solar radiation received by Earth, plate tectonics. Certain human activities have also identified as significant causes of recent climate change. Scientists actively work to understand past and future climate by using observations, more recent data are provided by the instrumental record. The most general definition of change is a change in the statistical properties of the climate system when considered over long periods of time. Accordingly, fluctuations over periods shorter than a few decades, such as El Niño, the term climate change is often used to refer specifically to anthropogenic climate change. Anthropogenic climate change is caused by activity, as opposed to changes in climate that may have resulted as part of Earths natural processes. In this sense, especially in the context of environmental policy, within scientific journals, global warming refers to surface temperature increases while climate change includes global warming and everything else that increasing greenhouse gas levels affect. A related term is climatic change, in 1966, the World Meteorological Organization proposed the term climatic change to encompass all forms of climatic variability on time-scales longer than 10 years, regardless of cause. Change was a given and climatic was used as an adjective to describe this kind of change, when it was realized that human activities had a potential to drastically alter the climate, the term climate change replaced climatic change as the dominant term to reflect an anthropogenic cause. Climate change was incorporated in the title of the Intergovernmental Panel on Climate Change, Climate change, used as a noun, became an issue rather than the technical description of changing weather. On the broadest scale, the rate at which energy is received from the Sun and this energy is distributed around the globe by winds, ocean currents, and other mechanisms to affect the climates of different regions. Factors that can shape climate are called climate forcings or forcing mechanisms, there are a variety of climate change feedbacks that can either amplify or diminish the initial forcing. Some parts of the system, such as the oceans and ice caps, respond more slowly in reaction to climate forcings. There are also key factors which when exceeded can produce rapid change. Forcing mechanisms can be internal or external. Internal forcing mechanisms are natural processes within the system itself

Monitoring (medicine)
–
In medicine, monitoring is the observation of a disease, condition or one or several medical parameters over time. It can be performed by continuously measuring certain parameters by using a monitor, and/or by repeatedly performing medical tests. Transmitting data from a monitor to a distant monitoring station is known as telemetry or biotelemetry, a small monitor worn by an ambulatory patient for this purpose is known as a Holter monitor. Cardiac monitoring can also involve cardiac output monitoring via an invasive Swan-Ganz catheter, hemodynamic monitoring, which monitors the blood pressure and blood flow within the circulatory system. Blood pressure can be measured either invasively through a blood pressure transducer assembly. Also, there are special patient monitors which incorporate the monitoring of brain waves, gas concentrations, bispectral index. They are usually incorporated into anesthesia machines, in neurosurgery intensive care units, brain EEG monitors have a larger multichannel capability and can monitor other physiological events, as well. Blood glucose monitoring Childbirth monitoring Body temperature monitoring through an adhesive pad containing a thermoelectric transducer and these allow for continuous monitoring of a patient, with medical staff being continuously informed of the changes in general condition of a patient. Some monitors can even warn of pending fatal cardiac conditions before visible signs are noticeable to clinical staff, a medical monitor or physiological monitor is a medical device used for monitoring. It can consist of one or more sensors, processing components, display devices, sensors of medical monitors include biosensors and mechanical sensors. Besides the tracings of physiological parameters along time, digital medical displays have automated numeric readouts of the peak and/or average parameters displayed on the screen, old analog patient displays, in contrast, were based on oscilloscopes, and had one channel only, usually reserved for electrocardiographic monitoring. Therefore, medical monitors tended to be highly specialized, one monitor would track a patients blood pressure, while another would measure pulse oximetry, another the ECG. Later analog models had a second or third channel displayed in the screen, usually to monitor respiration movements. Ambulatory telemetry can also be achieved by portable, battery-operated models which are carried by the patient and this newer method of charting patient data reduces the likelihood of human documentation error and will eventually reduce overall paper consumption. In addition, automated ECG interpretation incorporates diagnostic codes automatically into the charts, long-distance connectivity can avail for telemedicine, which involves provision of clinical health care at a distance. A medical monitor can also have the function to produce an alarm to alert the staff when certain criteria are set, an entirely new scope is opened with mobile carried monitors, even such in sub-skin carriage. This class of monitors delivers information gathered in body-area networking to e. g. smart phones, monitoring of clinical parameters is primarily intended to detect changes in the clinical status of an individual. For example, the parameter of oxygen saturation is usually monitored to detect changes in respiratory capability of an individual, when monitoring a clinical parameters, differences between test results can reflect either an actual change in the status of the condition or a test-retest variability of the test method
