1.5°C Target
Has the 1.5°C Target Actually Been Exceeded? What Does Science Say?
The issue of whether the current path toward the 1.5-degree Celsius target has been exhausted is at a critical stage in light of the findings presented by experts. Current measurements indicate that this limit is about to be crossed. The temperature increase is at the heart of the Paris Agreement, and United Nations data confirms this situation. This figure is not just a goal, but a limit that is difficult to overcome for the sake of protecting ecosystems. In the last twelve months, this line has been approached very closely, and in some periods, it has even been briefly surpassed. The reality is that the limit is no longer distant.
What is the 1.5°C Target?
This 1.5 degrees Celsius, the limit indicated in the Paris Agreement, shows how much global temperature should not increase compared to pre-industrial years. Scientists define this as an important line to prevent the destruction of natural balances. If the temperature exceeds this point, many forms of life will be in serious danger.
Why 1.5 Degrees?
When tipping points are reached, the climate system irreversibly
It is foreseen that processes that can have an impact will begin. Even half a degree more, when the temperature rises to 2°C instead of 1.5°C – glaciers melt rapidly while drought-stricken areas can expand. While seventy to ninety percent of coral reefs are damaged with a one-and-a-half-degree temperature increase, this situation becomes almost widespread when two degrees are reached. Extreme heat experienced by some people becomes much more severe with a 2°C temperature increase. In this case, the number of people affected is almost two and a half times higher compared to a 1.5°C increase. An ice-free Arctic Ocean in summer can be seen once every hundred years if the temperature reaches 1.5 degrees; when it rises to two degrees, this event will happen every ten years.
is expected.
Scientific Measurements
Scientists have long been aware that the climate is changing. Recent measurements show how much temperatures have risen. This increase is largely caused by factories and vehicles. This process, which has intensified particularly in the last century, has had a direct impact. According to the measurement results, the difference is now quite significant. Temperature values are clearly different from before. Gases produced by humans play a key role here. The observed change cannot be explained by natural cycles alone. The data also reveals that the process has accelerated compared to previous decades.
The increase is approximately between 1.1 and 1.2 degrees, and the main reports confirm this. These figures have been checked multiple times in the sources.
Emission Status
The rise in temperature does not stop where carbon runs out. The carbon dioxide released into the world these days, approximately forty billion tons annually, is causing a rapid decrease in this reservoir. It appears that what we have will not be enough to maintain the 1.5-degree limit. The usable rate will likely drop to zero sooner or later, and experts say this could happen before 2030. Time is running out, and the countdown continues. For some months, especially between 2023 and 2024, the measured heat globally has temporarily exceeded 1.5 degrees. However, when experts refer to such a situation, they are basing it on a twenty-year average.
Current Data
When analyzing future weather events, the World Meteorological Organization and the European Union's Copernicus Climate Change Service have confirmed that 2023 was the hottest year on record so far. The published information is based on January 2024 data. Over the past twelve months, global average temperatures have been 1.52°C higher compared to pre-industrial periods. This marks the first time the 1.5°C threshold has been surpassed in the short term. While the twenty-year average is a crucial benchmark, even a 12-month period offers significant insights. Looking at the trend, the temperature increase is progressing well ahead of expectations. Meanwhile, according to the IPCC's projections, if current policies remain unchanged, the limit will be exceeded by 2030.
Emissions Gap and the Economy
Küresel salınımlar azalmak yerine artış eğilimindedir. Halbuki 2030’a dek bu değerlerin %43 gerilemesi gerektiği hesaplanmaktadır. Şu anda yürürlükte olan kurallar altında, yüzyıl sonunda dünya sıcaklığının yaklaşık 2.5°C ile 2.9°C yükselmesi beklenmektedir. Bu durum Birleşmiş Milletler’in çevre kolu tarafından hazırlanan raporda açıkça ortaya konmaktadır. Ekonominin dengesi, 1.5 derece sınırının geride kalması halinde ciddi sarsıntı yaşayacaktır. 2024 verilerine dayalı finansal hesaplamalar, doğal afetlerin küresel gelire yıllık maliyetinin milyarlarca dolara ulaştığını göstermektedir. Sıcaklık iki derece daha tırmanırsa, GSYİH’ın onda birinden fazlasını kaybetmek söz konusudur.
Intervention and Harmonization Processes
Although scientists believe the 1.5°C limit might be technically achievable, policy momentum is not sufficient. To stick to this roadmap, carbon removal methods must advance more rapidly. Global balance may be possible if climate support increases in impoverished regions. Energy systems
Change has become a necessity for future generations. Regulations in industry not only protect nature but also determine the resilience of the economy.
Result
Although some believe the 1.5°C limit has already been passed, scientifically, we have not fully reached that point yet. Every temperature increase exacerbates disasters, weakens nature, and disrupts economic processes. The question of whether governments will act on science to leave a livable world for future generations is the fundamental responsibility of today's decision-making structures.
