Global warming causes
Name: Burbank School, Vicki S Maiden
What is the cause of global warming?
There are many causes, not just one, and we may not know what all the causes
are. There are natural causes that we know very little about but we know they
are there because geological evidence tells us that Earth's climate changes
quite a lot - sometimes colder than today and sometimes warmer. Some have
suggested changes in the sun's output of radiation, or changes in the amount
of dust in the atmosphere (from volcanoes or meteor impacts) as natural
causes. For about 100 years there has been concern that the burning of coal
and oil in our industrial age might put enough carbon-dioxide and other gasses
into the atmosphere to trap reflected sunlight and thus cause the atmosphere
to heat upage Various means of controlling industrial (and agricultural) air
pollution are being discussed by the world's governments.
Personally, I think
that we could adapt to a changing climate by distributing food and shelter
where it is needed. I am encouraged by the expansion of global peace and
global trade as evidence that humanity could cope with climate change no
matter what the cause.
