Global Warming

What is global warming?

https://climate.nasa.gov/faq/19/what-is-the-greenhouse-effect/#:~:text=Greenhouse%20gases%20include%20carbon%20dioxide,effect%20helps%20stabilize%20Earth's%20atmosphere.

These gasses include carbon dioxide, methane, nitrous oxides and water vapors.

Water vapors: Due to carbon dioxide, methane and nitrous dioxide water starts to evaporates from bodies of water and land areas which further adds heat to the atmosphere, increasing the global temperatures.

Nitrous oxide: It absorbs radiations and traps heat in the atmosphere

Methane: It comes from cows and is the worst gas out of all the greenhouse gasses, it traps 4 times as much as carbon dioxide.

Carbon dioxide: Traps heat into the atmosphere, ultimately raising global temperatures.

Global warming is when global temperatures start to rise in a certain amount of time due to the greenhouse emmisions continously trapping heat into our atmosphere.

What is caused by global warming?

Rising of sea levels: This is caused when large sheets of ice are melted. These sheets are melted due to the rising temperatures.

Storm intensity: When water is evaporated due to the heat in the atmosphere, this water becomes a type of fuel for a stronger storm.

Long period of droughts: When temperatures rise, land starts to dry easily which causes droughts, this occurs mostly in warm countries, countries near the equator.

Intense wildfires: Wildfires are caused because of the increasing temperatures, this makes it easier for fire to spread across a forest. When this happens more carbon dioxide enters the atmosphere and due to trees losing lives their are less trees left to then absorb carbon dioxide which further adds carbon dioxide in the atmosphere.

How are we effected by global warming?

Heatstrokes: Due to high temperatures some peoples bodies cannot handle the heat and they end up suffering a heatstroke. Countries near the equator are likely to face this problem due to the high temperatures.

Water deficiency: Due to high temperatures water gets evaporated leaving us humans with less to drink, if global warming gets worse we would continue to reduce our water supplies this can cause serious health problems like diarhea, polio and cholera.

Living conditions: Gases like carbon dioxide and methane are increasingly taking up our atmosphere. If this continues and humans continue to inhale carbon, high concentrated carbon dioxide this can create resperitory problems.

What causes global warming?

Methane is another gas that causes global warming. This gas is 4 times as worse as carbon dioxide and is produced from cows.

Global warming is caused when heat is trapped in the earth's atmospheres. Gasses like carbon dioxide are a main cause of global warming. Carbon dioxide is released into the atmosphere through:

https://www.usgs.gov/faqs/how-does-carbon-get-atmosphere

Burning of fossil fuels

Burning of natural gas

Burning of wood

Mining

Gasoline usage

Volcanic activity release large amounts of carbon dioxide into the atmosphere which adds the more amounts of carbon dioxide in our atmosphere.

How can we prevent global warming?

Saving energy reduces the amount of fossil fuels needed to power something. If less fossil fuels are used this would mean that there would be less carbon dioxide in our atosphere.

Recycle more helps to prevent global warming because it reduces the amount of energy required to produce a product. Instead of using metals, if used recyled items mining would be less, meaning lesser carbon dioxide would enter the atmosphere.

Planting trees removes carbon dioxide form the air because trees and other plants need carbon dioxide to survive.

switching to renewable sources of energy helps to prevent global warming because energy forms like solar or wind do not contrivute greenhouse gases like carbon dioxide or methane.
