Is Global Warming a threat to the Human Population?

Global warming has been a lot in the media and most people have probably discussed it and feared it for an amount of years now. In the media, Global Warming has been presented as a catastrophic event that will change the world as we know it, and have disastrous and horrible effects on us, and that it might be our demise. At first, scientists believed Global Warming to be a result of too much human activity, but as they years have passed and they have researched more, they now claim that Global Warming is a natural process which happens every now and then in a cycle with ice-ages. They now say that after an ice age, the earth will start to heat up, and that this process can take many years. Scientists say that the earth is now on the heating part of the cycle, and that human activities have just hastened the process a little, however the consequences of the heating period is still as catastrophic as they were when the process was caused by human activities alone.

Global warming has been discussed for a long time, and people have been worried about the consequences. Not so long ago, scientists believed that global warming was caused by human actions alone, which they had a good reason for, as the earth has been changing a lot since we first invented cars and started using fossil fuels. The earth’s changes happened in a pattern with the increase of CO2 emissions from humans that came from cars factories and more. This led the scientists to come up with their theory. However, lately scientists have pondered upon a new discovery, which they say reveals that global warming is not caused by our actions, only sped up by them. Apparently, global warming is now a result of a natural cycle of the earth, which occurs every now and then, in a cycle with ice ages. Scientists now believe that after an ice age, it is natural for the earth to go into a heating phase, where it warms up before cooling down again for another...
