Transcript of What causes and effects of the global warming ?

Global Warming Cause:
Carbon dioxide emissions from fossil fuel burning
Global Warming Cause:
Trees and forests absorb carbon dioxide from the atmosphere and convert it to oxygen.
As more trees are cut down, less carbon dioxide is absorbed.
This excess carbon dioxide that is released into the atmosphere combines with other greenhouse gases such as methane.
Global Warming Effect:
Thank you for your listening!!
Rise in sea levels worldwide
Glaciers and ice shelves around the world are melting.
The loss of large areas of ice on the surface could accelerate global warming.
Global Warming effects:
Extreme weather
What are the causes
and effects of the global warming ?

Global warming is one of the biggest issues in the world facing us right now. Its effects on animals and on agriculture are indeed frightening, and the effects on the human population are even scarier. The facts about global warming are often debated in politics and the media, but, unfortunately, even if we disagree about the causes, global warming effects are real, global, and measurable. The causes are mainly from us, the human race, and the effects on us will be severe.
Global Warming
Global warming happens just because too much carbon dioxide (CO2) goes into the atmosphere.
In brief:
Global Warming Cause:
Methane emissions
Global Warming Effect:
Disappearing of Plants, Animals, and Ecosystems
Fossil fuels contain high percentage of carbon.
When these fuels are burned, they react with oxygen and produce carbon dioxide.
since industrial revolution.
Methane is largely the same as natural gas, a fossil fuel, so it is contributing to global warming.
Methane is emitted by natural sources such as wetlands, human activities, melting tundra, belching cattle, and by some animal manure.

Heat Waves
Winter Weather
Disappearing of Habitats
Disappearing of Coral Reefs
Most plants and animals live in areas with very specific climate conditions, such as temperature and rainfall patterns, that enable them to thrive.
Any change in the climate of an area can affect the plants and animals living there, as well as the makeup of the entire ecosystem.
Warmer water has already caused coral bleaching (a type of damage to corals) in many parts of the world.
Experts predict that in 2050 the loss of coral reefs will reduce habitats for many other sea creatures, and it will disrupt the food web that connects all the living things in the ocean.

1) Fossil fuel: Fossil fuels are hydrocarbons, primarily coal, fuel oil or natural gas, formed from the remains of dead plants and animals.

2) Methane (CH4): It is a dangerous greenhouse gas that twenty times more powerful than carbon dioxide.

3) Coral bleaching: It is a type of damage to corals.Warmer water temperatures can result in coral bleaching. Corals can survive a bleaching event, but they are under more stress and are subject to mortality.
Flood eroded Venice for many years, the water sink 0.5 cm per year right now, with rising sea levels caused by global warming, if here is not rescued, Venice will soon be flooded.
