Climate Change and Global Warming Introduction.
Human Induced Global Climate Change Essay 2024 Words9 Pages Human-Induced Global Climate Change Worldwide temperatures are rising, carbon dioxide is at a hazardous level, ocean acidification, atmosphere boundary shifts, and extreme events are just a few of the worldwide climate changes happening near and far.
Many lines of evidence show that the warming of the past 50 years is primarily due to human activity. First, basic physics explains that greenhouse gases trap heat and thus increase temperature.
The human-induced buildup of greenhouse gasses in the atmosphere poses serious and diverse threats to life on earth.
Global warming is the ongoing rise of the average temperature of the Earth 's climate system and has been demonstrated by direct temperature measurements and by measurements of various effects of the warming.
The primary driver for increased global temperatures in the industrial era is human activity, with natural forces adding variability. Attribution of recent climate change is the effort to scientifically ascertain mechanisms responsible for recent global warming and related climate changes on Earth.
The extent of the human contribution to modern global warming is a hotly debated topic in political circles, particularly in the US. During a recent congressional hearing, Rick Perry, the US energy secretary, remarked that “to stand up and say that 100% of global warming is because of human activity, I think on its face, is just indefensible”.
Carbon dioxide is the main cause of human-induced global warming and associated climate change. It is a very long-lived gas, which means carbon dioxide builds up in the atmosphere with ongoing human emissions and remains in the atmosphere for centuries.
It is generally understood that human-induced climate change causes global warming, but what is not adequately appreciated are the direct influences on heavy rainfalls, drought, and storms, at great cost to society and the environment.
Scientists know that the warming climate is caused by human activities because: They understand how heat-trapping gases like carbon dioxide work in the atmosphere They know why those gases are increasing in the atmosphere They have ruled out other possible explanations.
Global warming is the observed increase in the average temperature of the Earth's atmosphere and oceans. Higher temperatures threaten dangerous consequences: drought, disease, floods, and lost ecosystems. From sweltering heat to rising seas, global warming's effects have already begun.
The “it” is global warming. “Global warming refers to the global-average temperature increase that has been observed over the last one hundred years or more” (Spencer). Some experts argue that global warming is a result of human activities, while others believe the warming and cooling of the Earth’s atmosphere is a natural cycle.
The effects of global warming or climate damage include far-reaching and long-lasting changes to the natural environment, to ecosystems and human societies caused directly or indirectly by human emissions of greenhouse gases.It also includes the economic and social changes which stem from living in a warmer world. Human caused climate change is one of the threats to sustainability.
The increased momentum in the shifting of the public views over the past years have led to controversy over whether global warming is real or not and whether human activities really contribute to its occurrence. research ha shown that the acts of skeptics of global warming is changing the view that people have on the issue regarding global warming and increasing number of individuals are a.

Common-usage definition: Warming caused by human activity.. What Causes Global Warming (climate change), human activity or the sun? The final answer is not in, but you can see the results so far. (1) Exhaust is clearly the source of CO 2. (2) Everyone now agrees the earth is warming. (3) Decide for yourself if warming is better explained by CO 2, or the sun’s heat. The Effects of Global.
Global warming has brought about possibly irreversible alterations to Earth's geological, biological and ecological systems. These changes have led to the emergence of large-scale environmental hazards to human health, such as extreme weather, ozone depletion, increased danger of wildland fires, loss of biodiversity, stresses to food-producing systems and the global spread of infectious diseases.
