9/24/ · The Effect of Global Warming. The impact that global warming is causing on earth is extremely serious. There are many hazardous effects that will happen in the future if global warming continues. It includes melting of polar ice caps, leading to an increase in sea level drowning coastlines and slowly submerging continents Global warming is, in essence, the gradual warming of the earth’s surface. The Earth’s average temperature is slowly rising, causing shorter and milder winter seasons in various countries around the world. But understanding global warming is nearly impossible without also having a base knowledge of another phenomenon: the Greenhouse Effect 3/16/ · Global warming, the phenomenon of rising average air temperatures near Earth’s surface over the past to years. Earth’s climate has changed over various timescales since the dawn of geologic time, and the force of human activities since the Industrial Revolution has been woven into the fabric of climate change
Global warmingthe phenomenon of increasing average air temperatures near the surface of Earth over the past one to two centuries. Increases in greenhouse gases —i. Continued global warming is expected to impact everything from energy use to water availability to crop productivity throughout the world. Poor countries and communities with limited abilities to adapt to these changes are expected to suffer disproportionately.
Global warming is already being associated with increases in the incidence of severe and extreme weather, heavy floodingand wildfires —phenomena that threaten homes, dams, transportation networks, and other facets of human infrastructure. Temperature increases related to global warming have been the most pronounced at the poles, where they often make the difference between frozen and melted ice. Polar bears rely on small gaps in the ice to hunt their prey. As these gaps widen because of continued melting, prey capture has become more challenging for these animals.
Giving voice to a growing conviction of most of the scientific communitythe Intergovernmental Panel on Climate Change IPCC was formed in by the World Meteorological Organization WMO and the United Nations Environment Program UNEP.
In the IPCC reported that the interval between and saw an increase in global average surface temperature of approximately 0. The increase is closer to 1. A special report produced by the IPCC in honed this estimate further, noting that human beings and human activities have been responsible for a worldwide average temperature increase of between 0. It predicted that the global mean surface temperature would increase between 3 and 4 °C 5.
The predicted rise in temperature was based on a range of possible scenarios that accounted for future greenhouse gas emissions and mitigation severity reduction measures and on uncertainties in the model projections, write a paragraph about the cause and effect of global warming.
Some of the main uncertainties include the precise role of feedback processes and the impacts of industrial pollutants known as aerosolswhich may offset some warming. Many climate scientists agree that significant societal, economic, and ecological damage would result if global average temperatures rose by more than 2 °C 3. Such damage would include increased extinction of many plant and animal species, shifts in patterns of agricultureand rising sea levels.
By all but a few national governments had begun the process of instituting carbon reduction plans as part of the Paris Agreementa treaty designed to help countries keep global warming to 1. Authors of a special report published by the IPCC in noted that should carbon emissions continue at their present rate, the increase in average near-surface air temperatures would reach 1. Past IPCC assessments reported that the global average sea level rose by some 19—21 cm 7.
It also predicted, again depending on a wide range of scenarios, that the global average sea level would rise 26—77 cm The scenarios referred to above depend mainly on future concentrations of certain trace gases, called greenhouse gasesthat have been injected into the lower atmosphere in increasing amounts through the burning of fossil fuels for industry, transportationand residential uses.
In the IPCC reported that concentrations of carbon dioxide, methane, and nitrous oxides in the atmosphere surpassed those found in ice cores dating backyears.
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 midth century, carbon dioxide concentrations in the atmosphere were write a paragraph about the cause and effect of global warming parts per million ppm. By the middle of they had risen to ppm, and, if fossil fuels continue to be burned at current rates, they are projected to reach ppm by the midst century—essentially, a doubling of carbon dioxide concentrations in years.
A vigorous debate is in progress over the write a paragraph about the cause and effect of global warming and seriousness of rising surface temperatures, the effects of past and future warming on human life, and the need for action to reduce future warming and deal with its consequences. This article provides an overview of the scientific background and public policy debate related to the subject of global warming. It considers the causes of rising near-surface air temperatures, the influencing factors, the process of climate research and forecasting, the possible ecological and social impacts of rising temperatures, and the public policy developments since the midth century.

An overview of the role greenhouse gases play in modifying Earth's climate.
During the second half of the 20th century and early part of the 21st century, global average surface temperature increased and sea level rose. Over the same period, the amount of snow cover in the Northern Hemisphere decreased. Top Questions.

Some incoming sunlight is reflected by Earth's atmosphere and surface, but most is absorbed by the surface, which is warmed.
Infrared IR radiation is then emitted from the surface. Some IR radiation escapes to space, but some is absorbed by the atmosphere's greenhouse gases especially water vapour, carbon dioxide, and methane and reradiated in all directions, some to space and some back toward the surface, where it further warms the surface and the lower atmosphere.

The Earth’s average temperature is slowly rising, causing shorter and milder winter seasons in various countries around the world. But understanding global warming is nearly impossible without also having a base knowledge of another phenomenon: the Greenhouse Effect There are several causes of global warming, which have a negative effect on humans, plants and animals. These causes may be natural or might be the outcome of human activities. In order to curb the issues, it is very important to understand the negative impacts of global warming.
