human beings responsible for global warming?
This question plagues many scientists. Consequently,
environmental researchers keep presenting
us with new evidence. They hope to prove
human responsibility for global warming
beyond a reasonable doubt. The problem is
there are those who say such research is
opponents of the environmental lobby argue
that the studies conducted by researchers
are often not collective enough or broad
enough in their scope. Some scientists study
air temperatures and others study ocean
temperatures but their data is not properly
argue that, to date, no scientific study
has proven an undeniable link between man-made
gas emissions and global warming. Let us
examine the arguments more closely: The
environmentalists claim that global warming
is responsible for many natural disasters.
believe that as the world becomes warmer
due to the heat-retaining gases we pump
into the atmosphere, our planet experiences
severe climatic upheaval. This upheaval
causes more droughts, more hurricanes and
tornadoes, and even phenomena like tidal
waves. Environmentalists believe we are
pushing our planet towards environmental
who oppose this view have a different argument.
They suggest that natural disasters and
wild weather have been around for millions
of years. The example they offer to prove
their argument is the El Nino weather phenomenon.
Have any of you heard of it? Well, El Nino
is an ancient weather phenomenon that sometimes
causes ocean temperatures to rise or tropical
winds to change direction.
changes often result in terrible storms
or flooding in certain areas of the Earth.
In other areas, it can even cause drought.
It's a totally natural phenomenon, as natural
as volcanic eruptions or earthquakes. So,
the opponents of the environmental lobby
think the argument that humans cause global
warming is hypothesis, not fact.
they complain that limiting emissions is
going to cost jobs and money. Until there
is indisputable proof linking greenhouse
gas emissions to increased global temperatures,
they tell us, there is no urgency in cutting
down on these emissions.
