CO₂ emissions continue to rise, according to the Global Carbon Budget. The average temperature for 2024 was 15.1 degrees Celsius. This is a record high, and 1.6 degrees above pre-industrial levels (the average temperature for 1850-1900).
This means that 2024 was the first year with global warming exceeding 1.5 degrees.
Does 1.5 degrees sound familiar? In the Paris Agreement, the world's countries agreed to keep global warming to well below 2 degrees, ideally below 1.5 degrees. The purpose of limiting warming to 1.5 degrees is to avoid tipping points in the climate system, i.e., climate changes that cannot be reversed. Additionally, there can be significant differences in the damages caused by climate arming, such as due to extreme precipitation, by keeping global warming below 1.5 degrees instead of 2 degrees.
Most climate researchers, however, agree that the goal of 1.5 degrees has already become unrealistic after many years without emission cuts.
One of these climate researchers is Jörg Schwinger. He, along with his NORCE colleague Siv Kari Lauvset, has contributed to the Global Carbon Budget. He finds news about record hot years or months litle interesting.
– We know that, as long as we emit CO₂, it will get warmer. Without the variability in the Earth system, for example due to El Niño/La Niña, which makes one year occasionally colder than the previous year, every single year would be warmer than all the previous ones, thus 'record warm,' he says.
Schwinger prefers to talk about something he finds difficult to communicate: Carbon Dioxide Removal. Schwinger and other climate researchers use the abbreviation "CDR," and for simplicity, we will use it in this article as well.
