The main causes and effects of global warming

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.

  • This is causing water shortages and an intense amount of distress to the over 2;
  • Evidence of warming is also apparent in living biological systems.

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.

Effects of global warming

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.

  • The first was that climate change would likely increase the number of people at risk of hunger compared with reference scenarios with no climate change;
  • The total annual power of hurricanes has already increased markedly since 1975 because their average intensity and average duration have increased in addition, there has been a high correlation of hurricane power with tropical sea-surface temperature.

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 since 1981, according 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.

  • Average temperatures around the world have risen by 0;
  • From which sectors do the major greenhouse gas emissions come from?
  • This graph is based on several studies;
  • Another source of methane is methane clathrate, a compound containing large amounts of methane trapped in the crystal structure of ice;
  • Changes in temperature and precipitation patterns increase the frequency, duration, and intensity of other extreme weather events, such as floods, droughts, heat waves, and tornadoes;
  • Most of the studies on global agriculture assessed by Schneider et al.

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 causes 300,000 deaths a year 9.

Widespread extinction of species According to research published in Nature, by 2050, rising temperatures could lead to the extinction of more than a million species. This is a concerning matter on many fronts.

  1. Trends for greenhouse gases.

  3. The coast can also be considered a region, and will suffer severe impacts from sea level rise. The Copenhagen diagnosis updating the world on the latest climate science.

Disappearance of coral reefs A report on coral reefs from WWF says that in a worst case scenario, coral populations will collapse by 2100 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.
