CLIMATE CHANGE


                CAUSES AND EFFECTS




Global Warming Cause: 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.

----------------------------------------------------------------------------------------------------

Global Warming Cause: Carbon dioxide emissions from burning gasoline for transportation

 With our population growing at an alarming rate, the demand for more cars and consumer goods means that we are increasing the use of fossil fuels for transportation and manufacturing.

----------------------------------------------------------------------------------------------------

Global Warming Cause: Deforestation, especially tropical forests for wood, pulp, and farmland.

 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.

----------------------------------------------------------------------------------------------------

Global Warming Cause: Increase in usage of chemical fertilizers on croplands.

 High nitrate levels in groundwater due to over-fertilization are cause for concern for human health.

----------------------------------------------------------------------------------------------------


Global Warming Cause: Methane emissions from animals, agriculture 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.

Global Warming Effect: Rise in sea levels worldwide


Many nations around the world will experience the effects of rising sea levels, which could displace millions of people


----------------------------------------------------------------------------------------------------


Global Warming Effect: More killer storms

The severity of storms such as hurricanes and cyclones is increasing

----------------------------------------------------------------------------------------------------

Global Warming Effect: Massive crop failures

According to recent research, there is a 90% chance that 3 billion people worldwide will have to choose between moving their families to milder climes and going hungry due to climate change within 100 years.

----------------------------------------------------------------------------------------------------

Global Warming Effect: Disappearance of coral reefs


The bleaching of corals from small but prolonged rises in sea temperature is a severe danger for ocean ecosystems, and many other species in the oceans rely on coral reefs for their survival.

----------------------------------------------------------------------------------------------------


Global Warming Effect: 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. And because we can’t exist without a diverse population of species on Earth, this is scary news for humans.
