CLIMATE CHANGE
Experts in climatology and other scientists are becoming extremely concerned about
the changes to our climate which are taking place. Admittedly, climate changes have
occurred on our planet before. For example, there have been several ice ages or
glacial periods.
These climatic changes, however, were different from the modem ones in that they
occurred gradually and, as far as we know, naturally. The changes currently being
monitored are said to be the result not of natural causes, but of human activity.
Furthermore, the rate of change is becoming alarmingly rapid.
The major problem is that the planet appears to be warming up. According to some
experts, this warming process, known as global warming, is occurring at a rate
unprecedented in the last 10,000 years. The implications for the planet are very
serious. Rising global temperatures could give rise to such ecological disasters as
extremely high increases in the incidence of flooding and of droughts. These in turn
could have a harmful effect on agriculture.
It is thought that this unusual warming of the Earth has been caused by so-called
greenhouse gases, such as carbon dioxide, being emitted into the atmosphere by car
engines and modem industrial processes, for example. Such gases not only add to the
pollution of the atmosphere, but also create a greenhouse effect, by which the heat
of the sun is trapped. This leads to the warming up of the planet.
Politicians are also concerned about climate change and there are now regular
summits on the subject, attended by representatives from around 180 of the world's
industrialized countries. Of these summits, the most important took place in Kyoto
in Japan in 1997. There it was agreed that the most industrialized countries would
try to reduce the volume of greenhouse gas emissions and were given targets for this
reduction of emissions.
It was also suggested that more forests should be planted to create so-called sinks
to absorb greenhouse gases. At least part of the problem of rapid climate change has
been caused by too drastic deforestation.
Sadly, the targets are not being met. Even more sadly, global warnings about climate
changes are often still being regarded as scaremongering.
