Global warming is a long-term rise in the average temperature of the Earth's climate system, an aspect of climate change shown by temperature measurements and by multiple effects of the warming.The term commonly refers to the mainly human-caused observed warming since pre-industrial times and its projected continuation, though there were also much earlier periods of global warming. In the modern context the terms are commonly used interchangeably,but global warming more specifically relates to worldwide surface temperature increases; while climate change is any regional or global statistically identifiable persistent change in the state of climate which lasts for decades or longer, including warming or cooling.Many of the observed warming changes since the 1950s are unprecedented in the instrumental temperature record, and in historical and paleoclimate proxy records of climate change over thousands to millions of years.
In 2013, the Intergovernmental Panel on Climate Change (IPCC) Fifth Assessment Report concluded, "It is extremely likely that human influence has been the dominant cause of the observed warming since the mid-20th century.The largest human influence has been the emission of greenhouse gasessuch as carbon dioxide, methane, and nitrous oxide. In view of the dominant role of human activity in causing it, the phenomenon is sometimes called "anthropogenic global warming" or "anthropogenic climate change". Climate model projections summarized in the report indicated that during the 21st century, the global surface temperature is likely to rise a further 0.3 to 1.7 °C (0.5 to 3.1 °F) to 2.6 to 4.8 °C (4.7 to 8.6 °F) depending on the rate of greenhouse gas emissions.These findings have been recognized by the national science academies of the major industrialized nationsand are not disputed by any scientific body of national or international standing.
Future climate change and associated impacts will differ from region to region.Anticipated effects include rising sea levels, changing precipitation, and expansion of deserts in the subtropics.Warming is expected to be greater over land than over the oceans and greatest in the Arctic, with the continuing retreat of glaciers, permafrost, and sea ice. Other likely changes include more frequent extreme weather events such as heat waves, droughts, wildfires, heavy rainfall with floods, and heavy snowfall;ocean acidification; and species extinctions due to shifting temperature regimes. Effects significant to humans include the threat to food security from decreasing crop yields and the abandonment of populated areas due to rising sea levels.Because the climate system has a large "inertia" and greenhouse gases will remain in the atmosphere for a long time, many of these effects will persist for not only decades or centuries, but tens of thousands of years.
Possible societal responses to global warming include mitigation by emissions reduction, adaptation to its effects, building systems resilient to its effects, and possible future climate engineering. Most countries are parties to the United Nations Framework Convention on Climate Change (UNFCCC),whose ultimate objective is to prevent dangerous anthropogenic climate change.Parties to the UNFCCC have agreed that deep cuts in emissions are requiredand that global warming should be limited to well below 2.0 °C (3.6 °F) compared to pre-industrial levels, with efforts made to limit warming to 1.5 °C (2.7 °F). Some scientists call into question climate adaptation feasibility, with higher emissions scenarios,or the two degree temperature target.
Public reactions to global warming and concern about its effects are also increasing. A global 2015 Pew Research Center report showed that a median of 54% of all respondents asked consider it "a very serious problem". Significant regional differences exist, with Americans and Chinese (whose economies are responsible for the greatest annual CO2 emissions) among the least concerned.

గ్లోబల్ వార్మింగ్ ......
గ్లోబల్ వార్మింగ్ అనేది ప్రస్తుత పరిస్థితుల్లో చాలా విషాదకరమైన పరిస్థితి. ఇది మనం వాడే వస్తువులు అనగా ఏసి, ఫ్రిడ్జ్ వంటివి కలుషితాలను మన వాతావరణంలో వ్యాప్తి చేయడం వల్ల వాతావరణంలో వేడి పెరిగి వచ్చే సమస్య.
ఇది కేవలం వస్తువులు వల్లే కాదు వాహనాల వల్ల కూడా కలుగుతుంది. దీనికి ముఖ్య కారణాలు కార్బన్ డయాక్సైడ్ వంటి గాలులు. వీటి శాతం వాతావరణంలో ఎక్కువ అవ్వడం వల్ల వాతావరణంలో తేమ, చల్లదనం తగ్గిపోయి వేడి పెరిగి మన హిమాలయాల వంటి ప్రదేశంలో కూడా మరణాన్ని దెబ్బతీసి తద్వారా మంచు కొండలు కరిగి నీటిమట్టం పెరుగుతూ ఉంటుంది.
దీని వల్ల ముంపు ఇతర సమస్యలు వస్తాయి కాబట్టి మన అందరం మన వస్తువులు వాడకాన్ని తగ్గించుకొని వాతావరణానికి క్షేమకరమైన పదార్థాలు వాడటం మంచిది.
