What is a global warming?
Generally, increasing the overall temperature due to emissions and builds up of greenhouse gases, which causes of increase in the levels of carbon dioxide CFCs and other pollutants.
“The greenhouse gases effect” is the warming, happens when certain gases in earth’s atmosphere trap the heat and keep the temperature of earth higher than it would be if direct heating by the sun is the only source of warming. When Sunlight reaches the surface of the earth, some of these absorbs the warm of ground and some bounces back to space as heat without greenhouse gases, the earth would very cool 0° F (-18°C). This trapped heat creates the greenhouse effect, which in turn contributes to climate change.
World Meteorological Organisation:-
The world meteorological organization team concluded that globally by the late 21st-century greenhouse warming would likely cause.
- The number of tropical cyclones to remain at current levels or to decrease by up to one-third.
“Tropical cyclones and climate” Nature Geo science, vol 3 157-163 (2010). The average intensity of cyclones to increase by up to 10%. Near-Storm rainfall rates to increase by about 20% Association.
American Meteorological Society:-
It widely clears from extensive, that rapid change in climate from the Past half century, human-induced increases in the amount of atmospheric greenhouse gases, including carbon dioxide (CO2), Chlorofluorocarbons, Methane and Nitrous oxide.
Global Temperature Rise:-
Temperature measured on land and at sea for more than one century shows, earth’s globally averaged surface temperature is rising, some areas are warm and some are cool. Since 1880, it has risen at an average pace of 0.13°F (0.07°C) every 10 years for a net warming of 1.71°F (0.95°C) through 2016.
Average Global Temperature:-
According to an ongoing temperature analysis conducted by scientists at NASA’s Goddard Institute for space studies (GISS), the average global temperature on earth has increased by about (0.8°) Celsius 1.4° F˚ since 1880. Two- thirds of the warming has occurred from 1975, at a rate of roughly 0.15-0.20°C Per decade.

The line plot below shows yearly anomalies from 1880 to 2014 as by NASA, NOAA. The Japan Meteorological Agency and the Met office Hadley center (United Kingdom). Though, there are minor variation every year. All for records show peaks and valleys in sync with each other. All show rapid warming in the Past few decades as warmest.
The causes of Global Warming:-
Greenhouse gases are mainly responsible for global warming, the severity of the situation confronting the world can well imagine. The Carbon dioxide has been increasing in atmosphere with the industrial revolution, because use of coal in immense quantities as fuel. Along with the vehicles already on the roads. At the same time cars come on the road, emit hundreds of thousands of tons of Carbon dioxide into the air every year. Man has been alerting the composition of the atmosphere only during the last five centuries or so. During the last 500 years, he has produced a greater worsening situation than took place during the previous 6 million years.
Global Climate Projections:-
According to “Global Climate Projections” in climate change (2007). “The physical science Basis” contribution of working group 1to the Fourth Assessment Report of the Intergovernmental Panel on climate change (2007). The climate change Consequences become the cause of global warming:
- Carbon Dioxide
- Nitrous oxide
- Water vapour
The consensus Position articulate from the Intergovernmental panel on climate change (IPCC) statement, human influence has the dominant cause of the observed warming since mid- 20th century (Qin et at 2014, p 17).
American Association For Advancement Of Science:-
The Pew Research centre (2015) conducted a detailed survey of 3748 members of the American Association for the Advancement of Science (AAAS) to assess views of several key science topics. Across this group, 87% agreed “Earth is warm mostly due to human activities”. (J cook et al) Environ Res Let.11 (2016) Among a subset of working PhD Earth Scientists, 93% agreed with this statement also.
2007 (IPCC) Report examined data on numerous changes of natural system have already observed as the Potential future impacts. The main reasons of changes in climate is heat and heat waves, rain snow, drought and stormy weather. The population growth increases or decreases in air pollution increases the ability to buy air conditioning or automobiles, and other social and economic changes are difficult to pin down decades into the future. (IPPC) indicates hot days, nights and waves have become more frequent globally in the last 50 years.
Here’s a look at some of the research at NCAR and in the winder research of community that focusing on the connections between global warming and earth’s ecosystems. The main prospects of changes in ecosystems are Polar and mountainous regions, plant life and wildlife.
According to NOAA (National oceanic and Atmospheric Administration). “Global Warming of the Past 50 years is primarily due to human activities predominantly the burning of fossil fuels”. Due to higher temperature, glaciers in Greenland and the Himalayas are melting fast, splits have appeared in iceburgs in Antarctica ocean waters are becoming warmer and more acidic, broadly affecting ocean circulation, chemistry of ecosystems and marine life. All these are evidences of rapid global warming.
ACS (American chemical Association):-
Future climates clearly indicate that climate change is very serious problem to the society and it is largely attribute to emission from human activities. According to the Fourth Assessment Report of the Intergovernmental panel on climate change 2, the average rate of global sea level rise over the 21st century will very likely exceed the observed from 1961- 2003 for a range of future emission scenarios.
Dangers Of Global Warming:-
The greatest dangers of global warming is the inundation of some of the world’s largest cities, which happen to be seaports due to the rise of the waters of the oceans from expansion. At the same time, floods, drought and sandstorms can displace millions of People.
How To Stop Global Warming?
All the countries of the world especially the industrial areas, should realize their responsibilities. They should take suitable steps to reduce the amount of carbon dioxide in the atmosphere. People should be careful about their daily needs and avoid unnecessary buying. When a shirt or shoe manufacture, energy spend, and pollutants generate. The population increasing relates to the global warming. .We can hope to able to persuade these people to reduce the number of their children by spreading first-class education. We should grow more and more trees to absorb carbon dioxide, while planning own and village, leave room for gardens and park; grow flower plants in our homes to keep the atmosphere less warm.
With today’s technology, man can live a life of luxury that could not even imagine a century ago. However, if all insist on each of us enjoying unlimited luxury, the day is not far off when we will all annihilate. Temperature is constantly rising. If it rises by about 10 degrees, life on this will become impossible. Act upon before it is too late. At Paris climate conference summit in 2015, 195 countries signed a historic agreement to control their carbon emission.
Latest Research Topics:-
Researchers will need to look more closely at what causes of changes to hurricane frequency and intensity. Internal climate variability on multi-decadal time scales may be important influence. However, studies should consider other natural and human influences, such as aerosols, volcanoes solar variation and greenhouse gases. There is much research remains to understand and predict these complex phenomena.
