I’ve had this conversation many times with friends, colleagues, family and yet, answers don’t cease to surprise me. According to wikipedia, Global warming is the unequivocal and continuing rise in the average temperature of Earth’s climate system. This causes several types of consequences such as temperature changes, extreme weather, melting of ice, decrease of water resources and even climate refugees (which I will talk about in another post someday…). The majority of people agrees with this definition.
So, what are the causes? Are we to be blamed? Well, it is here that opinions get divided.
Some of the people I’ve spoken to say that this is not due to human action. They say that the earth has had many phases in its cycle, such as ice age and others, and this is just another phase. Even if we weren’t here, there would have been an increase in temperatures on earth.
Others say that it is completely because of humans. We should stop using gases and materials that led to this problem.
Finally, there is a in-between opinion. Humans are not the sole responsible for global warming, but they caused, indeed, most of it. This opinion seems to be the one accepted by the majority of scientists (with some sceptics), although sometimes it seems that the majority of people doesn’t believe in this . The greenhouse gases, burning of fossils and other activities led to global warming.
Opinions aside, what can we do? Well, indeed we should reduce the use of certain types of gases, use alternative fuels, reduce the use of cars (ex: use more buses, trains, bicycles) or use electric/hybrid ones, recycle, make your house energy-efficient, etc.
I honestly think are we should be blamed for the majority of it. For years we’ve using these dangerous gases and harvesting earth’s resources without caring for the consequences.
And you? What is your opinion about global warming? What can we do to minimize its effects?
