Meaning: The quote by Bjorn Lomborg addresses the issue of global warming and its potential impact on the planet. Lomborg, a Danish author and statistician, is known for his skepticism about the severity of global warming and the effectiveness of certain proposed solutions. In this quote, Lomborg acknowledges the existence of a global warming effect and suggests that while the extent of warming may not reach the extreme projections of six degrees, a rise of two to three degrees could still have serious consequences.

The statement begins with Lomborg expressing his belief in the existence of a global warming effect, using the term "incontrovertible" to convey his conviction that it is an undeniable phenomenon. This indicates that Lomborg accepts the scientific consensus that the Earth's climate is undergoing significant changes as a result of human activities, particularly the emission of greenhouse gases.

By acknowledging the potential seriousness of the situation, Lomborg concedes that the impact of global warming could be significant, despite his skepticism about the more extreme projections. His mention of "two to three degrees warming" reflects the widely discussed goal of limiting global temperature rise to well below 2 degrees Celsius, as outlined in the Paris Agreement, and striving for efforts to limit the increase to 1.5 degrees Celsius.

Lomborg's reference to the potential seriousness of a two to three degrees warming aligns with concerns raised by climate scientists and researchers who warn about the adverse effects of such a temperature increase. These effects include rising sea levels, more frequent and severe extreme weather events, disruptions to ecosystems and agriculture, and threats to human health and well-being. Therefore, Lomborg's acknowledgment of the seriousness of this level of warming underscores the urgency of addressing climate change and its potential consequences.

It is important to note that Lomborg's views on global warming have been a subject of debate and controversy within the scientific community and among policymakers. While he acknowledges the reality of global warming in this quote, his overall stance on the issue, including his emphasis on the economic costs and benefits of climate policies, has been critiqued by many climate scientists and environmental advocates.

In conclusion, Bjorn Lomborg's quote highlights his recognition of the reality of global warming and the potential seriousness of a two to three degrees warming scenario. While his views on climate change have sparked debates and criticisms, his acknowledgment of the potential impact underscores the need for continued efforts to address and mitigate the effects of global warming. As the global community grapples with the challenge of climate change, Lomborg's perspective serves as a reminder of the importance of informed and inclusive discussions about the future of our planet.
