Introduction
During the heat wave of last summer, the man brazened and took into
consideration more than before the changes that our climate was undergoing. All
these qualitative changes in the normal parameters of the global climate, all
its alarming signs, make people doubt the stability of our current climate, and
more and more people are wondering what the consequences will be ...
So, we can ask ourselves what are these consequences really on the
biosphere?
Our researchers remain perplexed about this evolution of the
climate influenced by the man on the one hand, but also and especially by the
course of the time. They can only see the present consequences of climate
change on our planet, while expressing reservations about future consequences.
(Nº1)
The causes
The climate changes we are starting to witness are due to the
increase in greenhouse gas concentrations in the atmosphere. These effect gases
have always existed in the atmosphere in a natural way, and the most common of
these is water. But, for several decades, the most dangerous greenhouse gases
(CO2, NH4, ...) have grown exponentially whose origin is far from natural.
Today, human activities are the main cause of this increase in the
greenhouse effect: industries, transport, agriculture, buildings and energy
production are the main causes. These are all parts of society whose operations
need to be rethought.
Moreover, it is important to differentiate between the contribution
to the increase of greenhouse gases of the industrialized countries since more
than a century and the contribution of the countries currently in the process
of development (nº2)
The results
Global warming has serious consequences for humans and the
environment
-heating of emerged lands and high latitudes
-filling glaciers, decreasing or even disappearing in certain areas
of the ice in the Arctic and Antarctic
- rising sea level causing flooding in coastal areas, due to the
increase in water temperature, dilation of hot water making it larger than cold
water
-perturbation or destruction of some ecosystems
extinction of species
-extension of the desert
-recrudescence of infectious diseases, which will extend to the
North
-more intense heat waves
-Wetter rain more frequent and dense
-cyclones, typhoons and more intense hurricanes, with more severe
winds and precipitation and floods, causing serious human and material damage
-low of the drinking water resource
mass emigration of peoples undergoing global warming
The outlook for temperature increases is between 1.8 ° C and 4 ° C
by the end of the century, an increase that will not be uniformly distributed
on the planet: at the North Pole, the average temperatures of the last ten
years have increased 2 times faster than at the global level. (Nº3)
Conclusion
The climate of the planet will probably change quite significantly
during this century, largely because of human activities. The repercussions of
the current civilization will undoubtedly modify the situation of individuals,
regions, countries, and even continents and this on different elements of the
biosphere.
Moreover, the repercussions of these changes are already
perceptible at the living level and the natural risks that are increasing.
These climate changes will bring with them many negative effects that will
become more visible as we move forward in time.
