Many things cause global warming. One thing that causes global warming is electrical pollution. Electricity causes pollution in many ways, some worse than others. In most cases, fossil fuels are burned to create electricity. Fossil fuels are made of dead plants and animals. Some examples of fossil fuels are oil and petroleum. Many pollutants (chemicals that pollute the air, water, and land) are sent into the air when fossil fuels are burned. Some of these chemicals are called greenhouse gasses.
We use these sources of energy much more than the sources that give off less pollution. Petroleum, one of the sources of energy, is used a lot. It is used for transportation, making electricity, and making many other things. Although this source of energy gives off a lot of pollution, it is used for 38% of the United States' energy.
Some other examples of using energy and polluting the air are:
Turning on a light
Watching T.V.
Listening to a stereo
Washing or drying clothes
Using a hair dryer
Riding in a car
Heating a meal in the microwave
Using an air conditioner
Playing a video game
Using a dish washer
"Researchers at The Earth Institute say the recent water emergencies in some northeastern states resulted from more than just dry weather. They found droughts had a more direct, human cause called demand-driven drought.
A recent study, conducted by Bradfield Lyon of the International Research Institute for Climate and Society, Nicholas Christie-Blick of the Lamont-Doherty Earth Observatory and Yekaterina Gluzberg from the university's Department of Ecology, Evolution and Environmental Biology, examined precipitation variability and drought in Rockland County, N.Y., over the last 100 years.
The scientists discovered factors such as development, population growth and failing water supply systems played as significant a role as climate in creating the water emergencies.
"The balance between water demand and supply is now so finely tuned that even a few months of lower than normal precipitation is sufficient to trigger an emergency," said Christie-Blick.
The research appeared in a recent issue of the Journal of the American Water Resources Association."
Drought, and infertile land
over worked land and drought
over worked land and drought
Overworked land and drought were two things that contributed to the dustbowl.
moister in the ground causes it to expand so we a drought comes in to effect and all the moister evaporates the ground shrinks and the cracks form
Quickly evaporating rainwater causes most of the drought cycles
drought
El Nino
drought
A drought is an extended period of significantly below average precipitation in a region. NO, drought is a shortage of rainfall or dry weather!!!!!!!
There is no 'drought cycle' in Antarctica: Antarctica is always dry with little or no precipitation.
Drought, and infertile land
It causes drought. It becomes so hot
The opposite may be like a drought or similar a summer monsoon that causes rain and a winter monsoon which causes drought so there are some differences and similarity's
drought
Lack of rain in hot places like Indonesia and Australia will cause drought
War, drought, poor land management
