Climate change: UN warns – drastic measures now essential!
The UN is calling for urgent action on climate change ahead of the climate conference in Brazil as the 1.5 degree limit looms.
Climate change: UN warns – drastic measures now essential!
On November 5, 2025, global climate goals will take center stage as the world prepares for the upcoming climate conference in Belem, Brazil. A new UNEP report highlighting the urgent need to curb greenhouse gas emissions has revealed alarming findings. In 2024, the Earth recorded an increase in global average temperature of 1.5 degrees Celsius compared to the period before industrialization, inevitably leading to a small but noticeable increase in global greenhouse gas emissions to 57.7 billion tons of CO2.
The UNEP warns that it is “very likely” that global temperature rises will “exceed, at least temporarily, 1.5 degrees” in the next few years. Depending on political action, this development could result in warming of between 2.3 and 2.5 degrees by 2100. Given the current political framework, an increase of around 2.8 degrees is expected, which has a high probability of devastating consequences of up to 66%.
Urgent need for action
UNEP head Inger Andersen emphasizes that progress in climate protection is far from sufficient. To meet the 1.5 degree mark, a drastic reduction in CO2 emissions is required, with annual emissions having to be reduced by over 55% by 2035. This represents an enormous challenge, particularly for developing countries, which often suffer from the consequences of climate change.
The current forecasts are anything but rosy. If current policies are maintained, the Earth could suffer significant damage from climate change by the year 2100. Every additional 0.1 degrees Celsius will worsen the impact on human health and the environment. The poorest and most vulnerable populations are those struggling the most.
Technological solutions on the table
But there are also positive approaches. The switch from coal to renewable energies has already contributed to a significant reduction in CO2 emissions in some countries. Technologies to combat climate change exist and the development of wind and solar energy is exceeding our expectations. The UN also sees economic benefits in accelerating the implementation of climate protection measures. However, it is important that political and technical obstacles are overcome in order to find effective solutions.
Climate change, as a man-made crisis challenge, represents a major threat worldwide. In climate research, the discussion about the causes, such as the increase in greenhouse gases, is becoming increasingly important. The Earth has experienced a CO2 increase of over 400 ppm since the beginning of the industrial age. Historically, the current scenario is one of rather rapid change, which can also be influenced by supervolcano eruptions and changes in ocean currents.
It remains to be seen what decisions will be made at the upcoming climate conference. Many hope for real progress because one thing is clear: time for action is running out.
