Modern global warming is the result of an increase in magnitude of the so-called greenhouse effect, a warming of Earth’s surface and lower atmosphere caused by the presence of water vapour, carbon dioxide, methane, nitrous oxides, and other greenhouse gases.
Global warming refers to the gradual increase in the temperature of the Earth's surface, atmosphere and oceans as a result of greenhouse gases. Carbon monoxide emissions created by deforestation and burning fossil fuels create a barrier that traps the sun's heat on the Earth causing the planet to warm up.
The United Nations has been studying climate change and working to combat its effects since the first Earth Summit in 1992. The UN Intergovernmental panel's fifth report, published in late 2014, reiterates that global warming—more precisely called climate change—is happening and will likely not abate for centuries. The report also states with 95% certainty that the activity of humans has.
The Earth receives its warmth from the sun, so it's reasonable to suspect that our home star may be one of the reasons for global warming. Although the amount of energy coming from the sun does vary and may have been responsible for warming in the past, however, NASA and the Intergovernmental Panel on Climate Change (IPCC) have ruled this out as a cause of the current warming trend.
Global warming is a phenomenon of climate change characterized by a general increase in average temperatures of the Earth, which modifies the weather balances and ecosystems for a long time. It is directly linked to the increase of greenhouse gases in our atmosphere, worsening the greenhouse effect.
Global warming refers to global averages, with the amount of warming varying by region. Since the pre-industrial period, global average land temperatures have increased almost twice as fast as global average temperatures. This is due to the larger heat capacity of oceans and because oceans lose more heat by evaporation.
Causes of climate change. Global warming is caused by the greenhouse effect, a natural process by which the atmosphere retains some of the Sun’s heat, allowing the Earth to maintain the necessary conditions to host life.Without the greenhouse effect, the average temperature of the planet would be -18 0 C. The problem is that daily human activities maximize the greenhouse effect, causing the.
Causes of global warming. The human causes. of global warming have been in the news a lot in recent years. Human factors are the result of growing population and economic developments.
Environmental Pollution Our environment is affected by our daily actions. The earth is plagued with land, air and water pollution. Some of the problems we face on earth are: deforestation, nuclear waste, acid rain, global warming, overpopulation and some animals are endangered.
The diagram gives more details about this process, called the greenhouse effect. How the greenhouse effect works electromagnetic radiation at most wavelengths passes through the Earth's atmosphere.

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.
A flourishing life on land is the foundation for our life on this planet. We are all part of the planet’s ecosystem and we have caused severe damage to it through deforestation, loss of natural habitats and land degradation. Promoting a sustainable use of our ecosystems and preserving biodiversity is not a cause. It is the key to our own.
The Impact of Global Terrorism Essay;. We need to face many problems in our life. We have some global risk also. This year has been a notably rough year. Some of the worst threats make our people more worried. Many researchers and writers are writing about the biggest threats of the world. Several reports are also made to understand the.
Climate Change is the defining issue of our time and we are at a defining moment. From shifting weather patterns that threaten food production, to rising sea levels that increase the risk of.
Climate variability includes all the variations in the climate that last longer than individual weather events, whereas the term climate change only refers to those variations that persist for a longer period of time, typically decades or more. In the time since the industrial revolution the climate has increasingly been affected by human activities that are causing global warming and climate.
The greenhouse effect occurs when certain gases in the Earth's atmosphere (the air around the Earth) trap infrared radiation.This makes the planet become warmer, similar to the way it makes a greenhouse become warmer. The greenhouse effect is caused by greenhouse gases; the most important greenhouse gases in Earth's atmosphere are: water vapor, carbon dioxide(CO 2), and methane.
