Why are many scientists concerned about the increased concentration of carbon dioxide and other greenhouse gases in the atmosphere?

Answer 1

Many scientists are concerned about the increased concentration of carbon dioxide and other greenhouse gases in the atmosphere because it can begin to make earth unlivable. This would be because of extreme temperatures.

Answer 2

A:Scientists are concerned because temperatures are predicted to rise over the course of the twentieth century by between 1.1 and 6.4 degrees celsius, depending in part on the extent to which humans choose to reduce their greenhouse gas emissions. They are also concerned because the sea level rise, predicted to result from melting glacial ice and from sea water expansion, is between 0.9 and 1.5 metres over the same period. They anticipate disastrous climate change, with new drought and flood patterns as well as more frequent and intense storm activity. This will not only have a serious economic impact, but also cause ecological damage.

Answer 3

The glass in a greenhouse traps heat inside, providing certain plants with the climate they need. Similarly, greenhouse gasses (such as carbon dioxide and nitrogen) trap heat inside of Earth's atmosphere. As more and more greenhouse gasses are emitted due to pollution, more and more heat is trapped inside Earth's atmosphere, causing global climate change. Scientists are worried because the global climate change can cause disastrous effects on life as we know it. Already, the climate change has caused the melting of polar ice caps (which, if unhindered, will eventually cause the extinction of polar bears), the raising of sea levels (putting sea-level land communities in jeopardy), and the extinction of dozens of species (which can mess with the food chain and food web, causing the endangering and extinction of even more species).

Answer 4

scientist and government is concern about the greenhouse effect because it damages things in some places and it causes tons and flooding and government and scientist are putting or finding the best solution to stop it

Answer 5

Another contributor has written:

Greenhouse gas has become a matter of great public concern because the increase in concentrations of greenhouse gases in the atmosphere, resulting from human activity, is causing the world to become warmer. This might sound like warmer winters and balmy summer days, 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.

Answer 6

Because Greenhouse gasses have the effect of raising the temperature of the atmosphere. this will lead to all kinds of natural changes that may be harmful to the natural order of things.
