Welcome to the global web. Today, in this article, I will tell you and discuss the information about "Climate change" redirects here. For a broader discussion of climate trends throughout Earth's history,



Global warming is an increase in the average temperature of the Earth's climate system, mainly caused by humans, and has been proven by the measurement of direct temperature and the various effects of warming.  This is an important aspect of climate change, including its effects on increasing global surface temperatures, and changes in rainfall. 
IPCC has been used as a pre-industrial reference for NASA's observation temperature and the average of 1850-1900 K. [Driver] Human activity and natural forces add to the diversity of global warming in the industrial age. 
The Intergovernmental Panel on Climate Change (IPCC) concludes that "the impact of human impact on climate has been a major cause of warming since the mid-20th century."  These results have been recognized by the National Science Academies of major countries and are not disputed by any scientific or national institution.  Human impact is the emission of greenhouse gases such as carbon dioxide, methane and nitrous oxide. The burning of fossil fuels is a major source of these gases, and agricultural emissions and deforestation also play an important role.
Energy flows between space, atmosphere and the earth's surface. Current levels of greenhouse gases cause a radioactive imbalance of 0.9 W / m2. 
The effects of global warming include sea-level rise, regional changes in rainfall, extreme weather events such as heatwaves, and the spread of deserts.  The rise in surface temperatures is the largest in the Arctic, contributing to the decline of glaciers, perennial ice and sea ice. Generally, higher temperatures bring more rain and snowfall, but in some areas drought and forest fires increase.  Climate change can reduce coastal yields, impair food security, and rise in sea levels that damage coastal infrastructure.  Environmental impacts include the extinction or rehabilitation of many species, when their ecosystems change, immediately on coral reefs, mountains and the Arctic.  Some effects, such as loss of ice cover, increased water vapor, and permanent ice melt, produce reaction effects that increase the global warming rate.  CO is due to increased acid in the ocean
Although not driven by temperature, 2 levels are usually characterized by these effects. Several independently constructed instrument datasets confirm that the 2009–2018 decade was 0.93 ° 0.07 (C (1.67) 0.13 ° F) warmer than the pre-industrial baseline (1850–1900).  Currently, surface temperatures are increasing by 0.2 ° C (0.36 ° F) per decade.  Historical models of warming and cooling, such as medieval climate anomalies and the Little Ice Age, do not resemble current warming but can reach temperatures in limited areas by the end of the 20th century.  observed an increase in temperature and CO
 Densities occur so rapidly that even geological events in Earth history do not approach current rates.

Warmer and colder years:
While record years attract considerable media attention, individual years are less significant than global surface temperature and are subject to short-term fluctuations that overlap with long-term trends  Throughout this period, ocean heat storage continued to progress steadily upward, and in subsequent years, surface temperatures have skyrocketed. The slower rate of warming can be attributed to a combination of natural fluctuations, reduced solar activity, and increased sunlight reflected by particles from volcanic eruptions.
Greenhouse gases:

Greenhouse gases heat the Earth's heat from space into the trap.  This heat, in the form of infrared radiation, is absorbed and released by these gases in the atmosphere, resulting in less atmosphere and warming the surface. Prior to the Industrial Revolution, the temperature near the surface was 33 ° C (59 ° F) in the absence of natural greenhouse gases.  Regardless of the Earth's climate, Earth's average temperature is below the freezing point of water. Although water vapor (~ 50%) and clouds (~ 25%) are the main contributors to the greenhouse effect, they increase as a function of temperature and are therefore considered optimal.
2 (~ 20%), ozone and N

2O external force on the other hand.  The ozone acts as a greenhouse gas in the troposphere, the lowest layer of the atmosphere. In addition, it is highly reactive and interacts with other greenhouse gases and aerosols.
Surface change:
Humans mainly change the surface of the earth to create more agricultural land. Today, 50% of the world's arable land is occupied by agriculture, 37% is forested, and the latter is declining,  largely due to forest loss. Deforestation is an important component of land-use change that affects global warming. The main causes are deforestation of agricultural products such as beef and palm oil (27%), forest/forest products (26%), short-term agricultural crops (24%) and forest fires (23%). ). 

In addition to affecting greenhouse gas concentrations, land-use changes can also affect global warming through various chemical and physical dynamics. Changing vegetation in a location affects local temperature by changes in the amount of sunlight reflected in a space called albedo and the amount of heat lost by evaporation. For example, shifting from dark forest to pasture will make the surface lighter, reflecting more sunlight. Deforestation contributes to temperature changes by affecting deforestation and other chemical compounds affecting clouds; And when there are different constraints on the surface of the earth, changing wind patterns.  Globally, these effects are dominated by the growth of surface albedo, due to mild cooling. [There is] but there is considerable geographical diversity in this work.
