Carbon dioxide in the atmosphere is not a concern as long as the amount remains fairly constant, so that it helps sustain life and maintain our temperatue at a comfortable level, suitable for human existence. Because carbon dioxide is a greenhouse gas, the present rapid rise in its atmospheric concentration is a concern because it is leading to global warming and climate change.

A warmer world might even sound desirable, but the long-term global trend to higher average temperatures poses a real risk to our economic and social well-being, as well as to the native creatures with which we share the planet.

Climate change is causing sea levels to rise. Not by much so far, but this is only the start. Higher sea levels, combined with the greater storm surges associated with climate change, will force people to abandon some prestige coastal properties. The inundation of New Orleans should have been a wake-up call, but many see this as a special case with no relevance elsewhere. Rich agricultural coastal flood plains will become salinated and unproductive.

Floods will become more frequent and more severe in some areas, while droughts will similarly become more frequent and more severe in others. Analysis of hurricane activity shows that severe hurricanes are becoming more frequent and more destructive, as a result of increased atmospheric thermal energy. Frequent storm damage to properties will cause insurance premiums to rise until some can no longer even afford to insure their houses.

Wildlife will suffer from loss of appropriate habitat and from heat stress. Some corals will die back as sea levels rise and they no longer receive sufficient sunlight, while others will be bleached by the rising temperatures and acidity.

Scientists who are concerned about increased carbon dioxide in the atmosphere believe global warming is caused by?

... the burning of fossil fuels, which is adding extra carbon dioxide to the greenhouse gases in the atmosphere.


What is the probable reason for the increase of carbon dioxide?

Our burning of fossil fuels (coal, oil and natural gas) in industry, transport and the generation of electricity is more than the probable reason. Scientists agree that it, and deforestation, is the definite reason for the increase of carbon dioxide (CO2) in the atmosphere.


What is an increase in CO2?

This means an increase in the amount of carbon dioxide (CO2) in the atmosphere. There is a normal balance of carbon dioxide in the atmosphere. Trees and green plants soak it up, and then when the trees rot or are burnt the carbon dioxide goes back into the atmosphere. However, more than 200 years ago we began seriously burning coal and oil. This released carbon dioxide that had been trapped millions of years ago. So over the years the amount of this gas in the atmosphere has been increasing. Most climate scientists agree that this increase in carbon dioxide is contributing to climate change and global warming.


What human activities contribute to the increase of carbon dioxide in the atmosphere?

Human activities that contribute to the increase of carbon dioxide in the atmosphere include burning fossil fuels for energy, deforestation, and industrial processes.


Where do scientists think extra carbon dioxide is coming from?

Scientists believe that the extra carbon dioxide in the atmosphere primarily comes from human activities, such as burning fossil fuels for energy, deforestation, and industrial processes. These activities release carbon that has been stored in the Earth for millions of years, contributing to the increase in atmospheric carbon dioxide levels.

Ice samples from glaciers provide evidence that today's atmosphere contains more carbon dioxide than ancient atmosphere on earth did.why id this increase in carbon dioxide a concern to scientists?

It is of no concern to scientists - its just data. However, it is a concern to the human beings who are also scientists since their environment is getting fouled up.
