Is the greenhouse effect harmless

Answer 1

There is a natural greenhouse effect that has kept the earth warm enough for life for many millions of years.

There is now an enhanced (or accelerated) greenhouse effect which is causing global warming.

The consequences of the enhanced greenhouse effect are certainly not harmless. Climate scientists predict many dangers in the future, including famines, heat waves, species extinction and sea level rising to dangerous levels.

Answer 2

The damage and impact that greenhouse gases leave on the earth varies depending on the type of gases. Gases such as Nitrogen Oxides tend to be less damaging to the air, although their presence does damage to plant life. Gases such as Methane are naturally occurring and severely damage the ozone layer. More dangerous gases such as hydroflurocarbon and perflurocompounds tend to do far more damage to the ozone layer and to the oxygen quality. It is important to note that the largest emitter of greenhouse gases are companies that work in the energy extraction and distribution sectors (power stations).

Answer 3

The natural greenhouse effect keeps the earth warm enough for life.

The enhanced (or accelerated) greenhouse effect (from our burning of fossil fuels) is causing global warming.

Answer 4

In the beginning it was OK, it was doing a good job keeping the Earth warm. But now the trouble is its doing its job "too well".
