Denialists have always been there, ever since we started talking about global warming. Yet the reality is now before everyone’s eyes, amid increasingly extreme natural events, crop losses, endangered animals and the many other effects of climate change. However, influential people like Donald Trump have the courage to deny global warming by claiming that it is colder. But this is just the tip of the iceberg. Let’s see together what are the most famous fake news about climate change.
And most of all, let’s see how to break them down with science.
This is maybe the biggest fake news about climate change. Climate scientists have no doubt about the existence of climate change and human responsibility. We should not confuse the opinions of climatologists with those of scientists who work in completely different fields.
The IPCC (Intergovernmental Panel on Climate Change) is the main body dealing with climate change.
It brings together scientists and researchers from all over the world, among the top experts in the field. There is unanimous agreement among them. Everyone believes that global warming is a reality, that it is mainly due to human activities and that it is one of the greatest dangers for us.
It is true that climate has changed in the history of the Earth. In this case, however, it is happening because of man and not because of natural causes. It is also happening with an alarming speed.
To reply to those who say that the lowering and raising of temperatures is natural, you need only to look at the Oceanic and Atmospheric Administration database. It has been measuring the global average temperature since 1880. According to the data collected, the only trend in temperatures is that of growth. In fact, the last 5 years have been the hottest since surveys began.
Those who do not want to deny the evidence of the increase in global temperature, caused by the increase in the concentration of greenhouse gases, claim this. They admits that the problem is there, but it is not related to human activity. They often say that it is the fault of solar activity or that the CO2 emitted by man is only a small percentage. As a result, there is no need to limit it because this will not affect the climate.
CO2 emissions also occur in nature, it is true. However, the difference is that they have always been balanced by proper absorption by oceans and forests. Until mankind broke this balance by burning fossil fuels, the concentration of CO2 in the atmosphere has always been constant. Since 1800, however, it has been constantly increasing. Suffice it to say that recently we have exceeded 415 pmm, values never reached in 800,000 years. In addition, oceans and forests manage to absorb less and less CO2.
