Climate Change
Climate change is a
significant and lasting change in the statistical distribution of weather patterns over periods ranging
from decades to millions of years. It may be a change in average weather
conditions, or in the distribution of weather around the average conditions (
more or fewer extreme weather events). Climate change is caused by factors such
as biotic processes,
variations in solar radiation received by
Earth, platetectonics, and volcanic eruptions. Certain
human activities have also been identified as significant causes of recent
climate change, often referred to as global warming.
The most general
definition of climate change is a change in the statistical
properties of the climate system when considered over long periods of time,
regardless of cause. Accordingly, fluctuations over periods shorter than
a few decades, such as El Nino, do not represent
climate change.
Without
the unity in global politics world doesn't stand the chance against climate
change. Hopefully, world leaders will realize this before it's too late. Though
as some say world could already be too late to do something about it.
