Greenhouse gases question?

Question

Green house effects are necessary to keep the planet habitable, and have been strong in the past. Why is the current rapid change a worry?

Answer 1

We are destroying the trees and other green things so we can pave the space over. The trees of the Amazon are the largest converters of carbon dioxide on the planet, and humans are burning them to plant cash crops in their place. Unfortunately, the biomass of the crops are not nearly as competent in converting the CO2 to O2, so we lose more of the balance to CO2.
Further, we are burning oil and other fossil fuels at a rate higher than anytime in history, so the discharge of CO2 from combustion tips more the balance.
Our atmosphere, when richer in CO2 absorbs more of the heat of sunlight than does the oxygen-rich atmosphere.
The interesting thing is the double impact of this: less sunlight hits the Earth, slowing the growth of plants, while the atmosphere gets warmer, helping the plants grow. This makes the statistics a little more confusing, and feeds facts to the disclaimers of global warming. We need less fuel to heat our homes, so we burn less for heat and have more for transportation of products and persons. This changes the balance of payments throughout the world, making the higher lattitudes more productive, with a smaller energy bill, so they are more competitive. The USA considers itself a higher lattitude country, so we throw our international weight with the pro-global warming group - especially our industrialists. The warmer it is in Washington, DC, the less Congress hears the lament of fears about global warming and sees the economic advantages.

Answer 2

The main concern is the amount of greenhouse gases entering the atmosphere since about 1750. Methane and carbon dioxide are natural parts of nature, and nature has ways to absorb and recycle them.
But the atmosphere and biosphere can only handle so much at one time, and we have been pumping these gases (and continue to do so) faster than the planet can achieve balance.

Not just by the gases we produce, but by destroying ecosystems such as rainforests that serve as natural filters and recycling systems to keep the planet in balance.

Answer 3

It's a problem for two reasons:

First--a change in the level of greenhouse gases-such is occuring becuause of the release of massiveamounts of CO2 by burning fossil fuels--destroys the equilibrium that keeps climate stable. As a result, we are going to see the current droughts, wildfires,e tc. get steadily worse.

Second, while these things do occur naturally, a natural change occurs slowly--over thousands of years. Taht gives various species--plants and animals--time to adapt. The current global warming is happening in a matter of a few decades. That kind of rapid change doesn't allow species tie to adjust--and will destroy local and regional ecosystems. For humans, this means radical changes in our environment--including, among other things, a possible devastating reduction in our ability to produce food.

Answer 4

Because our agricultural and socioeconomic system cannot handle any change. At all. What are farmers in the US gonna do when the corn belt moves north into Canada? Migrate? And where are the people of Bangladesh, a country of some 100 million people situated at sea level, gonna do when their entire country is flooded? Animals can move. Animals can adapt. Humans can´t and that´s why any climate change is a real threat to humanity.

Answer 5

There is a theory that green house gases are depleting our ozone layer and if that happens the greenhouse effect will run rampant ant the planets ice caps not to mention glaciers will melt and it will cause worldwide flooding. Just Google it.... Read read read.

Answer 6

Hi. Because ice melts at 32 F (0 C) and we are very near that temperature now. Also water (as with most materials) expands as the temp increases. When it starts to warm on a global scale the water in the oceans will expand and the levels will increase. Physics, pure and simple.

Answer 7

because too much greenhouse gas is not natural
the polar ice caps are not supposed to be melting and all that extra water will soon creep up and swallow a lot of the land
and plus the irregularity in the climates also causes worries, extremes such as drought and flooding is not balanced
