D2 interviewed author Thomas Horne on September 22 about so-called climate deniers, who deny that human greenhouse gas emissions contribute to climate change.
According to Horne, we have never had climate change that has occurred as rapidly as it has in the past 150 years. It’s not true. An example is the so-called Dansgaard-Oeschger events during the last ice age, when temperatures in the North Atlantic Ocean repeatedly rose by at least five degrees over forty years. The UN climate panel writes that the warming we are seeing now is probably the fastest in at least 2,000 years.
Horne also suggests that climate change will lead to more hunger. The UN climate panel, on the other hand, expects that the number of hungry people in the world will fall by several hundred million people by 2050, even without further climate measures. The climate panel assumes that people’s adaptability and therefore food production will remain much more important for our well-being than climate change.
Humans’ great adaptability is illustrated by what happened with the 1991 Pinatubo volcanic eruption. As Horne notes, such eruptions emit little CO2 compared to what humans do. However, such volcanoes emit a lot of sulfur. So much so that the average temperature on Earth fell by 0.5 degrees in the 15 months after the Pinatubo eruption. We hardly remember this temperature drop. The reason for this is probably because it did not have much significance for humans, even though the temperature change occurred much faster than the general warming we are experiencing now.
It is important to contribute to a fact-based public debate, and it is an issue where many Norwegians doubt that climate change is happening or is caused by humans. But with exaggerated claims about the effects of climate change, we risk causing even more people to doubt the climate science facts.(Conditions)Copyright Dagens Næringsliv AS and/or our suppliers.
