The climate has been a much debated topic for some time now, but there is still a lack of clarity about it. There are many Wild West stories circulating in which even politicians and the media are taking part. But which stories are based on truth and which can be dismissed as nonsense? We have compiled a list of 5 scientifically substantiated facts about the climate for you.
1. The climate is always changing
If you look at the temperature data and proxy values over the last 10,000 years, you will see that the climate has always been subject to change. All climate scientists agree on this. It goes from cold to warm and vice versa.
2. The rise in temperature in the past was not caused by humans
Industrialisation only began in the 18th century. Before that, very little CO2 was emitted by humans. Yet the temperature rose before the 18th century as well. In the last 2,000 years, the temperature on earth has risen at least twice (around the 1st and 10th centuries) to a level comparable to the current temperature on Earth. Neither rise was caused by humans.
3. The ice caps are doing better than ever
Yeah, you heard right. The ice caps of the North and South Poles are doing better than ever. The over 10,000-year-old Holocene paleoclimatic data shows that both the North and South Poles are in very good condition. The only period in which they did better was in the 17th century, during the Little Ice Age. Despite the great losses in recent years, the ice level is still close to historical highs.
4. Polar bears and other polar animals don’t die out, but prosper
If you look at the previous fact, it’s obvious. Polar bears, often used as the symbol of climate doomsday, are one of the Arctic’s most important animal species.
Contrary to what most people believe, however, the polar bear is not dying out. In fact, in the last 20 years, many more polar bears have been added. So many, in fact, that the government of Canada was considering increasing the hunting quota on these animals because they threaten inshore communities.
5. CO2 is not a climate change agent
Most climatologists who work with the United Nations believe that the Earth warms up faster because of CO2 emissions. However, no empirical evidence has been found for this.
The temperature on Earth, measured between 2000 and 2016, did not increase, while CO2 emissions did. This is evidence that CO2 does not play a major role in global warming.
And if we finally look again at the paleoclimatic data of the last 10,000 years, it is clear that CO2 is not the climate changer of which it is accused. The Earth heats up and cools down, even without the emission of large amounts of CO2.
