UN climate conference in Bonn: Study: CO2 budget for 1.5-degree destination shrinks rapidly

According to a report, the remaining CO2 budget, in order to permanently limit global warming to 1.5 degrees, will be used up in a little more than three years at the current level of climate-damaging emissions.

The so-called CO2 budget refers to the amount of CO2 that can still be expelled if a certain mark of global warming is not to be exceeded.

The budgets to stabilize the ear heating at 1.6 or 1.7 degrees could be exceeded within nine years. This is in the annual report of the Science Initiative Indicator of Global Climate Change (IGCC), which was presented at the UN Climate Conference in Bonn.

Previous climate protection is not sufficient

The main author of the study, Piers Forster, said the investigation shows that the efforts to limit global warming were far from sufficient. The rapid pace of warming is primarily due to the continued high emissions of greenhouse gases. The CO2 emissions from fossil fuels and the deforestation of the forests would therefore have to be shut down to zero.

Sea levels rose by more than 20 centimeters

According to the study, the sea level rose an average of around 26 millimeters per year between 2019 and 2024. This has more than doubled the long -term sea level increase since the beginning of the 20th century. Aimée Slangen, research manager at the Royal-Dutch Institute for Sea Research, said that since 1900 the average sea level has increased by about 22.8 centimeters worldwide.

“This apparently small number has oversized effects on low -located coastal areas, makes storm surges harmful and causes more coastal erosion,” says Slangen. “The worrying is that we know that the sea level increases relatively slowly in response to climate change, which means that we have already planned a further increase in the coming years and decades.”

The study was created by a team of more than 60 international scientists. The aim is to provide the latest scientific knowledge about how the climate system changes and what influence the person takes. The IGCC initiative builds on the central climate skills, which are also reported by the World Climate (IPCC) and provides current data annually.

1.5-degree goal has not yet been officially torn

In the Paris climate agreement, it was agreed in 2015 to limit global warming to 1.5 degrees as possible above the pre -industrial level. The year 2024 was the first since the start of the measurement after a report by the EU program Copernicus’s climate change service, which was an average of over 1.5 degrees worldwide than in pre-industrial means.

However, this does not yet mean that the limit set in the Paris Agreement has already been exceeded. The agreement refers to temperature deviations that are average over a period of at least 20 years.

Nevertheless, the 1.5-degree limit is now considered hardly accessible among experts. In order to keep global warming under this brand in the long run, the output of climate -damaging greenhouse gases would have to drop quickly and strongly – around 43 percent by 2030. In addition, large amounts of greenhouse gases in the atmosphere would have to be withdrawn. Instead, there is currently a recdering in many countries in climate protection-especially in the United States under US President Donald Trump.
