Short term effects of global warming are:
1) Abnormally warm temperatures in the Winter and Summer months in various areas of the planet (actually throughout the year, but most easily contrastable in those seasons)
2) Deaths of certain forms of life that are not as adaptable to such temperature changes
3) Increases in glacial and ice cap melting, producing increases in sea level
4) Deaths of certain forms of life due to (3)...such as coral, which can only survive in certain pH levels, which changes in the sea as more fresh water is introduced into the oceans due to Arctic/Antarctic ice melting
5) Increases in the severity of certain storm patterns (such as tropical cyclones) and even local weather patterns
6) Increases in drought conditions in various areas
Global warming will increase the size of deserts.Rising sea levels will submerge some landforms.
There are many fears of scientists who write about global warming. Ozone depletion, floods, warming etc are some of them.
I do not believe that the normal air pressure of the Earth as a whole is terribly effected by so called "global warming". Maybe at higher altitudes where the air is actually "thinner(less oxygen content) there may be some effects but it is probably negligible.
Because it blocks out some of the UV rays and blocking some of those rays keep some heat from commig in so, that is less heat that the green house gasses can absorb
Eutrophication, the pacific garbage patch, over population of invasive species in some areas, global warming effects, etc.
True global warming does not decrease temperatures. So, either the model for global warming's effects is hokus-pokus, or global warming as presently claimed, does not exist. Some global warming followers will have you believe that global warming makes the weather "act crazy". If true, then it is not really global warming, is it.
Global warming.
humans cause global warming and pollution
driving cars, pollution and lots more?!
Cause: Global Warming Effect: Glacier Melting
First you try to understand the harmful effects of global warming. Then go to peoples house in your locality and show some percentage of global warming in their house. Then explain them its harmful effects. Then try to tell them how to prevent it. Make posters and stick it on walls. Take out a rally with your friends.
Global warming, Deforestation and Decreasing Biodiversity,etc.
There are many dicesases due to air pollution. Also it cause for global warming.
You can find videos on youtube.com. Type global warming into the search.
There are thousands of slogans that are available for stopping global warming. Some of these slogans include "Global Warming: We have a solution, stop pollution" and "Penguins are on Thin Ice: Stop Global Warming".
Yes, we have known about global warming since about the middle of last century, but governments have been slow to act. Politicians rarely can see beyond the next election, and action on global warming takes some years before we see a result. Now, as global warming and its effects are beginning to be more obvious governments may act.
History of climate change throughout the years, factors causing global warming such as methane gas and water vapor, the effects of CO2 on temperature is probably over-done, but something comparing the amounts of say, CO2 and water vapor in the atmosphere and their relative effects on insulating the atmosphere and the ensuing global warming would be more original.
