information on global environmental issues and problems

Numerous ecologists, conservation biologists, and other scientists studying climate warn that rising surface temperatures will bring about an increased extinction risk. When there is increased concentration of such gases in the atmosphere mostly by burning fossil fuels, there is a proportionate increase in the temperature of the Earth’s atmosphere. These five megatrends present major global threats for planet Earth — problems that must be solved if the world is to remain a supportive habitat for humans and other species. Be on the lookout for your Britannica newsletter to get trusted stories delivered right to your inbox. Climate change is now a much-discussed concept around the globe. The planet is warming, from North Pole to South Pole. Population growth and the resultant increase in human habitations in the last couple of centuries has taken away a considerable portion of natural vegetation, cultivable lands, and above all the natural habitats of wild animals. Globally, 1998 was the warmest year and the 1990s was the warmest decade on record. Contribution may be by submission or invitation, and suggestions for special issues and publications are welcome. Many countries have experienced increases in rainfall, particularly in the countries situated in the mid to high latitudes. It is called global warming. Massive and unplanned urbanization and industrialization over the last century. As a result, environmental degradation has risen to an irrecoverable level. As global warming alters these patterns on timescales considerably shorter than those that arose in the past from natural climate variability, relatively sudden climatic changes may challenge the natural adaptive capacity of many species. A large fraction of plant and animal species are likely to be at an increased risk of extinction if global average surface temperatures rise another 1.5 to 2.5 °C (2.7 to 4.5 °F) by the year 2100. In high-latitude ecosystems, changes in the seasonal patterns of sea ice threaten predators such as polar bears and walruses; both species rely on broken sea ice for their hunting activities. Rapid global warming can affect an ecosystems chances to adapt naturally. Most resources being finite since the very beginning and natural limit to resource generation being slow, constant rise in the number of people on the earth exerts undue pressure on world resources. The global average surface temperature is believed to have increased by 0.6° + 0.2° C over the last century. IJGEnvI aims to establish channels of communication between government agencies, professionals, academic experts and policy makers. There has been loss of biodiversity and resultant ecological imbalance in severity in the current times. The Arctic is very sensitive to climate change and already seeing lots of changes. All of these changes are emerging as humans continue to add heat-trapping greenhouse gases to the atmosphere. Resource depletion, environmental degradation, and pollution have become the order of the day. Changes could be experienced in the rainfall or snowfall pattern, temperature, etc. © 1996-2015 National Geographic Society, © 2015- 2 Minute Read The planet is warming, from North Pole to South Pole. These include threats to habitats and organisms on land and underwater, as well as resource depletion. may submerge under water, Climate change is making food crops less nutritious. Submitted articles should not have been previously published or be currently under consideration for publication elsewhere. Issues. Large parts of the U.S., for example, face a higher risk of decades-long ", Less freshwater will be available, since glaciers, Some diseases will spread, such as mosquito-borne. Apart from the pressure on the resources due to high growth in population, technological and scientific innovations, rapid rise in automobile population, electronic gadgets, machinery and equipment have added a great number of pollutants to the environment. Not only the huge population (7.4 billion in 2016), but also the lifestyle, consumption patterns in modern time directly affect the environment. The study also predicted that 16 percent of Earth’s species would be lost if surface warming increased to about 4.3 °C (7.7 °F) above preindustrial temperature benchmarks.

Climate change encompasses not only rising average temperatures but also extreme weather events, shifting wildlife populations and habitats, rising seas, and a range of other impacts. Warmer winters in the Korean peninsula and southern Europe have allowed the spread of the Anopheles mosquito, which carries the malaria parasite, whereas warmer conditions in Scandinavia in recent years have allowed for the northward advance of encephalitis. Changes in precipitation create changes in the availability and quantity of water and also results in extreme weather events, such as intense storms, flooding and droughts. It is because it is now experienced that the world temperature is increasing during these years. Most scientists say that human activities have caused certain changes in the natural climate of the earth. As a result, fish and other organisms that forage upon algae and plankton may be threatened. The environmental consequences of climate change are extreme heat waves, rising sea levels, changes in precipitation resulting in flooding and droughts, intense hurricanes, and degraded air quality. Globall… Changes could be experienced in the rainfall or snowfall pattern, temperature, etc. Warmer winter conditions in New York in 1999, for example, appear to have facilitated an outbreak of West Nile virus, whereas the lack of killing frosts in New Orleans during the early 1990s led to an explosion of disease-carrying mosquitoes and cockroaches. More people demand more resources and generate more waste. This includes mountain glaciers, ice sheets covering West Antarctica and Greenland, and Arctic sea ice. Consumption, although necessary for the economy, can be hazardous to the environment. Consumerism has become more acute in developing countries such as India and China than that in developed countries due to the rise in population in the former. Consumerism is a social and economic order that supports and encourages the acquisition of goods and services in ever increasing amounts. The heat is melting glaciers and sea ice, shifting precipitation patterns, and setting animals on the move. Excessive demand for consumer products has created most of the current environmental imbalances and these imbalances have already caused ecological disaster in different places all over the world. Also in the high latitudes, a combination of warming waters, decreased sea ice, and changes in ocean salinity and circulation is likely to lead to reductions or redistributions in populations of algae and plankton.

Professionals, academics, researchers and policy makers. Man has developed an unprecedented craze for a mushrooming number of products and services available in the world market. Nonetheless, sustainable development can be pursued more easily when population size is stabilized at a level consistent with the productive capacity of the ecosystem. Cross section of a generalized coral polyp. And how does it relate to global warming? Earth’s distance from the sun, volcanic eruption at large scale, heavy rainfall for longer period, are the instances of natural phenomena that influence the Earth’s climate. With the advent of science and technology man’s need for comfort and luxury has multiplied many times. Clearly one of the challenges of a growing population is that the mere presence of so many people sharing a limited number of resources strain the environment. to maintain their desired lifestyles. Burning of fossil fuels such as coal, petroleum, and natural gas at huge scale to meet the growing energy needs of the bulging world population. Cloud forests—tropical forests that depend on persistent condensation of moisture in the air—are disappearing as optimal condensation levels move to higher elevations in response to warming temperatures in the lower atmosphere. Developed countries where the levels of consumption are high add more to pollution than other countries. Species loss estimates climb to as much as 40 percent for a warming in excess of 4.5 °C (8.1 °F)—a level that could be reached in the IPCC’s higher emissions scenarios. Learn about the impact and consequences of climate change and global warming for the environment and our lives. Climate change is also a change in Earth’s climate. Learn how global warming affects the migratory pattern of birds. List of topics covered include social, political, economic and environmental issues, including human rights, economy, trade, globalization, poverty, environment and health related issues. The above phenomenal changes directly and indirectly affect the physical, social, and psychological health of human beings. These include: https://www.nationalgeographic.com/environment/global-warming/global-warming-effects.html, the global average surface temperature has increased by more than 1.6 degrees, rising 0.13 inches (3.2 millimeters) a year, store about three-quarters of the world's freshwater, Ice is melting worldwide, especially at the Earth’s poles. Scientists already have documented these impacts of climate change: Other effects could take place later this century, if warming continues. 2020 National Geographic Partners, LLC. More specifically, changes to near-surface air temperatures will likely influence ecosystem functioning and thus the biodiversity of plants, animals, and other forms of life. Global warming could therefore affect the spread of infectious disease through its influence on ENSO or on severe weather conditions. They are loosely divided into causes, effects and mitigation, noting that effects are interconnected and can cause new effects. In 2015 one study that examined 130 extinction models developed in previous studies predicted that 5.2 percent of species would be lost with a rise in average temperatures of 2 °C (3.6 °F) above temperature benchmarks from before the onset of the Industrial Revolution.
