Global warming kya hai

What Is Climate Change? Climate change refers to long-term shifts in temperatures and weather patterns. Such shifts can be natural, due to changes in the sun’s activity or large volcanic eruptions. But since the 1800s, Burning fossil fuels generates greenhouse gas emissions that act like a blanket wrapped around the Earth, trapping the sun’s heat and raising temperatures. The main greenhouse gases that are causing climate change include carbon dioxide and methane. These come from using gasoline for driving a car or coal for heating a building, for example. Clearing land and cutting down forests can also release carbon dioxide. Agriculture, oil and gas operations are major sources of methane emissions. Energy, industry, transport, buildings, agriculture and land use are among the Humans are responsible for global warming Climate scientists have showed that Many people think climate change mainly means warmer temperatures. But temperature rise is only the beginning of the story. Because the Earth is a system, where everything is connected, changes in one area can influence changes in all others. The People are experiencing climate change in diverse ways Climate change can affect our health, ability to grow food, housing, safety and work. Some of us are already more vulnerable to climate impacts, such as people living in small island nations and other developing countries. Conditions like sea-level rise and saltwater intrusion have advanced to the point where whole communitie...

Of all these gases, carbon dioxide is the most important, both for its role in the greenhouse effect and for its role in the human economy. It has been estimated that, at the beginning of the industrial age in the mid-18th century, carbon dioxide concentrations in the atmosphere were roughly 280 parts per million (ppm). By the end of 2022 they had risen to 419 ppm, and, if fossil fuels continue to be burned at current rates, they are projected to reach 550 ppm by the mid-21st century—essentially, a doubling of carbon dioxide concentrations in 300 years.

Climatology is the study of the atmosphere and weather patterns over time. This field of science focuses on recording and analyzing weather patterns throughout the world and understanding the atmospheric conditions that cause them. It is sometimes confused with meteorology, which is the study of weather and weather forecasting. However, climatology is mainly focused on the natural and artificial forces that influence long-term weather patterns. Scientists who specialize in this field are called climatologists. The first studies of climate can be traced back to ancient Greece, but climate science as it is now known did not emerge until the advent of the industrial age in the nineteenth century. The science of climatology grew as scientists became interested in understanding weather patterns. In recent times, climatologists have increasingly focused their research on the changes in Earth’s climate that have occurred since the industrial age. Earth has been growing warmer and warmer as human industry has expanded and released more carbon into the atmosphere. This effect, called global warming, is a particularly important object of study for climatologists. By studying global warming, climatologists can better understand and predict the long-term impact of human-caused climate change. Climatologists seek to understand three main aspects of climate. The first aspect is the weather patterns that govern normal conditions in different regions throughout the world. Secondly, climat...

• v • t • e The politics of climate change results from different perspectives on how to respond to Climate change Different responsibilities, benefits and climate related threats faced by the world's nations contributed to early climate change conferences producing little beyond general statements of intent to address the problem, and non-binding commitments from the developed countries to reduce emissions. In the 21st century, there has been increased attention to mechanisms like Since entering the 2020s, the feasibility of replacing energy from fossil fuel with Policy debate Like all policy debates, the political debate on climate change is fundamentally about action. The statements that form political arguments can be divided into two types: Actions in response to climate change can be divided into three classes: Most 20th century international debate on climate change focused almost entirely on mitigation. It was sometimes considered defeatist to pay much attention to adaptation. Also, compared to mitigation, adaptation is more a local matter, with different parts of the world facing vastly different threats and opportunities from climate change. By the early 21st century, while mitigation still receives most attention in political debates, it is no longer the sole focus. Some degree of adaptation is now widely considered essential, and is discussed internationally at least at high level, though which specific actions to take remain mostly a local matter. A commitment...

जलवायु परिवर्तन पर निबंध (Essay on climate change in hindi) - जलवायु एक ऐसा पहलू है जो दुनिया के हर इंसान के जीवन से जुड़ा हुआ है और जलवायु की दशा हमारे जीवन को बहुत प्रभावित करती है। इस तथ्य को इस बात से समझा जा सकता है कि अनुकूल जलवायु के कारण ही पृथ्वी पर जीवन संभव हो पाया है, लेकिन मानवीय और कुछ प्राकृतिक गतिविधियों के कारण जलवायु की दशा बदल रही है। इस स्थिति को जलवायु परिवर्तन (Climate change- क्लाइमेट चेंज) की संज्ञा दी जाती है। हाल के वर्षों और दशकों में गर्मी के कई रिकॉर्ड टूट गए हैं: यूएन जलवायु रिपोर्ट 2019 इस बात की पुष्टि करती है कि रिकॉर्ड में साल 2019 दूसरा सबसे गर्म वर्ष था, और 2010-2019 सबसे गर्म दशक। वरà¥...
