Global Warming Impacts and Effects

The effects of Global Warming can already be seen.

The IPCC's Third Assessment Report finds that in the last 40 years, the global average sea level has risen, ocean heat content has increased, and snow cover and ice extent have decreased, which threatens to inundate low-lying island nations and coastal regions throughout the world.

Does Global Warming Effect Our Fauna and Flora? Sure it does!

Global warming is having a significant impact on hundreds of plant and animal species around the world -- although the most dramatic effects may not be felt for decades, according to a new study in the journal Nature.

"Birds are laying eggs earlier than usual, plants are flowering earlier and mammals are breaking hibernation sooner,"

"Clearly, if such ecological changes are now being detected when the globe has warmed by an estimated average of only 1 degree F (0.6 C) over the past 100 years, then many more far-reaching effects on species and ecosystems will probably occur by 2100, when temperatures could increase as much as 11 F (6 C)."

We can't really feel the effect and impact on us right? What about in the future?

Global warming will have serious impacts on the environment and on society. Higher temperatures will cause a melting of ice in Greenland and Antarctica. This will accelerate the rise of sea level. The speed at which global warming is expected to occur in the 21st century is faster than most plant and animal species will be able to cope with. Some will adapt but others will suffer and may become extinct.

 

Global warming will affect agriculture. New crops will be able to be grown in areas that are currently too cold to support them. However, more pests and diseases may offset any benefits higher temperatures may have. Water resources will also be affected. Some reservoirs may dry up if temperature increases, especially if rainfall also decreases. Rising sea levels may pollute fresh groundwater supplies with salt water.

 

Global warming will also affect human health. There may be more heat-related illnesses in hotter summers, and increased breathing problems as higher temperatures increase air pollution in cities, reducing air quality. The malaria mosquito may also be able to spread to other regions of the world where it is currently too cold to survive and breed.

 

More extreme weather, for example storms, floods and droughts will have severe impacts on the environment and on society. The poorest people in society will unfortunately be those least able to cope with the impacts of global warming.

Natural Causes that caused Global Warming

Natural causes are causes that are created by nature. One natural cause is a release of methane gas from arctic tundra and wetlands. Methane is a greenhouse gas and a very dangerous gas to our environment. A greenhouse gas is a gas that traps heat in the earth's atmosphere. Another natural cause is that the earth goes through a cycle of climate change. This climate change usually lasts about 40,000 years.

Finn stop this attitude

This is interesting Willis, could these natural disasters have been caused by global warming and cause a cycle effect.

Man-Made Causes that caused Global Warming

Man-Made Causes that caused Global Warming | Cause and Effects of Global Warming | Scoop.it

Man-made causes probably do the most damage to our planet. There are many man-made causes of global warming. Pollution is one of the biggest man-made problems. Pollution comes in many shapes and sizes. Burning fossil fuels is one thing that causes pollution. Fossil fuels are fuels made of organic matter such as coal, or oil. When fossil fuels are burned they give off a green house gas called CO2. Also, mining coal and oil allows methane to escape. How does it escape? Methane is naturally in the ground. When coal or oil is mined you have to dig up the earth a little bit. When you dig up the fossil fuels you dig up the methane as well letting it escape into the atmosphere.

 

Another major man-made cause of Global Warming is population. More people means more food, and more methods of transportation. That means more methane because there will be more burning of fossil fuels (if you're into gas burning cars like our planet is), and more agriculture. If you've been in a barn filled with animals and you smelled something terrible, you were smelling methane. Another source of methane is manure. Because more food is needed to feed the population we have to raise food. Animals like cows are a source of food which means more manure and hence more methane. Another problem with the increasing population is transportation. More people means more cars, and more cars means more pollution. Also, many people have more than one car. There are definitely ways of raising animals and farming that use no manure and no methane. Once we realized the problem we should have stopped immediately using manure. Instead we choose to continue killing the planet. We are a very stubborn race.

 

Since CO2 contributes to global warming, the increase in population makes the problem worse because we breathe out CO2. Also, the trees that convert our CO2 to oxygen are being cut down because we're using the land that we cut the trees down from as property for our homes and buildings. We are not replacing the trees (trees are a very important part of our eco-system), so we are constantly taking advantage of our natural resources and giving nothing back in return.
