The climate has suffered many changes throughout the eras of our planet. Weather patterns and natural phenomena have changed entirely many times in the course of history. Everybody is interested about the changes in our climate, but is it true that is happening now and in a way that can radically affect living species, including humans?
Many studies have identified global warming as being the major problem that affects global climate. Moreover, studies point that 95% of global warming is due to human activities and, in the future, can lead to extreme weather events that will affect the entire planet. Though there are voices that deny that there’s a significant change in the weather, the vast majority of the international scientific community agrees that climate change is happening at a fast rate and that human activities are to be held responsible for this. The deniers, also known as skeptics, generally argument that the climate change is not happening as rapidly as predicted, that it will not affect humankind or other species and that it may even have positive effects. These arguments are, however, contradicted by the large number of studies on the topic and visible climate changes that bring overwhelming proof that drastic events are taking place right now and not into a positive direction.
It would be difficult to calculate the consequences of climate change on the long term, but these may include a series of negative effects that may prove fatal for life on Earth as we know it. First and foremost, certain weather hazards, like tornadoes and hurricanes will become more violent, which means more of a threat for all living beings on the planet. Not only that but, more dangerous weather hazards can affect agriculture in unpredictable ways. As such, food ratios will indirectly be at risk. If this continues for a prolonged period of time, it can lead to lack of food and global starvation.
In addition to that, global warming can result into the disappearance of approximately 20-30 % of the species living on Earth now. Another consequence of the phenomenon is that the cryosphere (the frozen water on our planet) will meltdown and thus, increase the sea level. The planetary ocean will become warmer and will gain more acidity. These changes will reflect on species such as corals and shellfish and many others that are sensitive to temperature fluctuations. Moreover, species such as polar bears that are dependent on ice can face dangerous trials and even extinction. In time, climate change will affect the chemical composition of the atmosphere, which may inevitably take an unfavorable turn for all living creatures and may even provoke their death, if these fluctuations become too radical.
The effects of climate change are various and hard to calculate, as they can affect most processes going on on Earth. Some of them will generate others that will affect other processes and so forth. The consequences are too complex and can only be approximated or guessed no matter how detailed the scientific research is. However, though we cannot exactly predict what will happen if the natural rhythm will be derailed, we know that its effects will most probably be negative and transform the Earth into an inhospitable environment for its inhabitants.
