Average temperatures around the world have risen by 0. This is creating the global warming we see today. These findings are recognized by the national science academies of all the major industrialized countries.
Global Warming Effects and Causes: A Top 10 List 1. Carbon dioxide emissions from fossil fuel burning power plants Our ever increasing addiction to electricity from coal burning power plants releases enormous amounts of carbon dioxide into the atmosphere.
Every day, more electric gadgets flood the market, and without widespread alternative energy sources, we are highly dependent on burning coal for our personal and commercial electrical supply. Our consumption is outpacing our discoveries of ways to mitigate the effects, with no end in sight to our massive consumer culture.
Methane emissions from animalsagriculture such as rice paddies, and from Arctic seabeds Methane is another extremely potent greenhouse gas, ranking right behind CO2. When organic matter is broken down by bacteria under oxygen-starved conditions anaerobic decomposition as in rice paddies, methane is produced.
The process also takes place in the intestines of herbivorous animals, and with the increase in the amount of concentrated livestock production, the levels of methane released into the atmosphere is increasing. Another source of methane is methane clathrate, a compound containing large amounts of methane trapped in the crystal structure of ice.
As methane escapes from the Arctic seabedthe rate of global warming will increase significantly. Deforestationespecially tropical forests for wood, pulp, and farmland The use of forests for fuel both wood and for charcoal is one cause of deforestation, but in the first world, our appetite for wood and paper products, our consumption of livestock grazed on former forest land, and the use of tropical forest lands for commodities like palm oil plantations contributes to the mass deforestation of our world.
Forests remove and store carbon dioxide from the atmosphere, and this deforestation releases large amounts of carbon, as well as reducing the amount of carbon capture on the planet. Increase in usage of chemical fertilizers on croplands In the last half of the 20th century, the use of chemical fertilizers as opposed to the historical use of animal manure has risen dramatically.
In addition to these effects, high nitrate levels in groundwater due to over-fertilization are cause for concern for human health.
Scientists predict an increase in sea levels worldwide due to the melting of two massive ice sheets in Antarctica and Greenland, especially on the East coast of the U. However, many nations around the world will experience the effects of rising sea levelswhich could displace millions of people.
One nation, the Maldives, is already looking for a new home, thanks to rising sea levels. More killer storms The severity of storms such as hurricanes and cyclones is increasingand research published in Nature found: The maximum wind speeds of the strongest tropical cyclones have increased significantly sinceaccording to research published in Nature this week.
And the upward trend, thought to be driven by rising ocean temperatures, is unlikely to stop at any time soon. One of the main causes of this will be the spread of desertification, and its accompanying effects.
It causes more violent swings between floods and droughts. Global warming causesdeaths a year 9. Widespread extinction of species According to research published in Nature, byrising temperatures could lead to the extinction of more than a million species.
This is a concerning matter on many fronts. Disappearance of coral reefs A report on coral reefs from WWF says that in a worst case scenario, coral populations will collapse by due to increased temperatures and ocean acidification and its effects.
For reefs, warming waters and acidification are closing in like a pair of jaws that threaten to make them the first global ecosystem to disappear.Sep 28, · Global Warming: News, Facts, Causes & Effects. Global warming is the term used to describe a gradual increase in the average temperature of the Earth's atmosphere and its oceans, a .
Nov 15, · Global climate change has already had observable effects on the environment. Glaciers have shrunk, ice on rivers and lakes is breaking up earlier, plant and animal ranges have shifted and trees are flowering sooner. Global warming is the current increase in temperature of the Earth's surface (both land and water) as well as it's atmosphere. Global warming is caused by the increase of greenhouse gases in our atmosphere. The predicted effects of global warming are many and various, both for the environment and for human life. There is some speculation that global warming could, via a shutdown or slowdown of the.
Impacts of Global Warming Global warming is already underway with consequences that must be faced today as well as tomorrow. Evidence of changes to the Earth's physical, chemical and biological processes is now evident on every continent.
A: Global warming occurs when carbon dioxide (CO2) and other air pollutants and greenhouse gases collect in the atmosphere and absorb sunlight and solar radiation that have bounced off the earth. The effects of global warming are the environmental and social changes caused (directly or indirectly) by human emissions of greenhouse gases.
There is a scientific consensus that climate change is occurring, and that human activities are the primary driver. The predicted effects of global warming are many and various, both for the environment and for human life.
There is some speculation that global warming could, via a shutdown or slowdown of the. An overview of the impacts of global warming, including sea level rise, more frequent and severe heat waves, increasing wildfire risks, and more.
Many are already taking place today -- and will only get worse as temperatures continue to rise.
