EFFECTS OF GLOBAL WARMING! (GLOBAL WARNING!)
The effects, or impacts, of climate change may be physical, ecological, social or economic. Evidence of observed climate change includes the instrumental temperature record, rising sea levels, and decreased snow cover in the Northern Hemisphere.[3] According to IPCC (2007a:10), "[most] of the observed increase in global average temperatures since the mid-20th century is very likely due to the observed increase in [human greenhouse gas] concentrations". It is predicted that future climate changes will include further global warming (i.e., an upward trend in global mean temperature), sea level rise, and a probable increase in the frequency of some extreme weather events.

Effects/Impacts of Global Warming:
The following are some of the effects of Global Warming on Earth (taken as well as about to take place) & are quite noticeable:
- Melting of Permafrost: The permafrost or permafrost soil is a soil at or below the freezing point of water (0 degree celcius). Most of the Arctic area is covered by the permafrost. And this permafrost is seeming to be melting which would dramatically worsen the global warming effect by releasing massive amounts of greenhouse gases thereby enhancing the greenhouse effect.
- Bangladesh under Water: The Catastrophe in Bangladesh has begun. Due to great rises in the sea levels, Bangladesh's One-Third part is under Water.
- Along with these hot temperatures, Australia has consequently experienced some if its driest months and severest drought.
- In 2007, Northern England experienced a whole months worth of rain in just a few hours in many places.
- Southwest Pakistan was hit by monsoon floods affecting 800,000 and Indonesia experienced intense storms which left more than 340,000 homeless.
- Ukraine experienced their worst drought in a century, which cut crop yields by 60% and resulted in a rapid increase in food crops.
- Tokyo (the capital of Japan) had never gone so late without snow in the winter season according to the Japan Meteorological Agency.
- As northern countries warm, disease carrying insects migrate north, bringing plague and disease with them.
- As the temperature of oceans rises, so will the probability of more frequent and stronger hurricanes.
- Hurricanes cause do billions of dollars in damage, diseases cost money to treat and control and conflicts exacerbate all of these.
- With a two degree increase Greenland will tip into irreversible melt (accelerating sea-level rise and threatening coastal cities around the world).
- Polar Bears and other species that require a stable ice platform for survival will become extinct in the Arctic.
- A three degree increase will result in Perth, Sydney and other parts of Australia experiencing water shortages, the world will experience a net food deficit, the Amazonian ecosystem will collapse and glacial retreat in the Himalayas means the Indus River will run dry and millions of environmental refugees will flee Pakistan.
- A four degree increase in temperature will lead to a third of Bangladesh being threatened by rising seas and millions will become climate refugees.
- All glaciers will disappear in the Alps.
- A five degree increase means the earth will become hotter than any other time in 55 million years and methane hydrate will be released from underneath oceans resulting in tsunamis in coastal regions.
- Finally, a six degree increase will lead to the mass extinction of species including Humans.
In short, Global warming is affecting many parts of the world. Global warming makes the sea rise, and when the sea rises, the water covers many low land islands. This is a big problem for many of the plants, animals, and people on islands. The water covers the plants and causes some of them to die. When they die, the animals lose a source of food, along with their habitat. Although animals have a better ability to adapt to what happens than plants do, they may die also. When the plants and animals die, people lose two sources of food, plant food and animal food. They may also lose their homes. As a result, they would also have to leave the area or die. This would be called a break in the food chain, or a chain reaction, one thing happening that leads to another and so on.
The oceans are affected by global warming in other ways, as well. Many things that are happening to the ocean are linked to global warming. One thing that is happening is warm water, caused from global warming, is harming and killing algae in the ocean.
Algae is a producer that you can see floating on the top of the water. (A producer is something that makes food for other animals through photosynthesis, like grass.) This floating green algae is the food to many consumers in the ocean. (A consumer is something that eats the producers.) One kind of a consumer is small fish. There are many others like crabs, some whales, and many other animals. Fewer algae is a problem because there is less food for us and many animals in the sea.
Global warming is doing many things to people as well as animals and plants. It is killing algae, but it is also destroying many huge forests. The pollution that causes global warming is linked to acid rain. Acid rain gradually destroys almost everything it touches. Global warming is also causing many more fires that wipe out whole forests. This happens because global warming can make the earth very hot. In forests, some plants and trees leaves can be so dry that they catch on fire.
